The transportation apparatus includes: i) A storage volume (120) for ESD-shielding storage of the component carrier and/or the component carrier preform, ii) a locking element (130) for locking the storage volume, iii) a locking control unit (140) coupled with the locking element and configured to: a) Opening the locking element when the operator (400) is authorized, and b) bringing the locking element to a closed position when the operator is unauthorized; and iv) a wireless communication device (150) configured to communicate with an external device information related to the transportation device.
Description
Technical Field
The present invention relates to a mobile electrostatic discharge (ESD) shielding transport device for component carriers and/or component carrier preforms. The invention may also relate to a mobile ESD shielded transport device loaded with component carriers (preforms), a transport device system comprising a plurality of transport devices, and a transport device organization system. Furthermore, the invention may relate to a method of transporting a component carrier (preform) in an ESD shielded manner and to the use of a wireless communication device.
Background
As the product functions of component carriers equipped with one or more electronic components are growing, and miniaturization of such electronic components, and the number of electronic components mounted on the component carrier (such as a printed circuit board) are increasing, increasingly powerful array-like components or packages having several electronic components are being used, which have a plurality of contacts or connection portions, and the pitches between these contacts are becoming smaller. Removal of heat generated during operation of such electronic components and component carriers themselves is becoming an increasingly important issue. At the same time, the component carrier should have mechanical robustness as well as electrical and magnetic reliability in order to operate even under severe conditions.
In particular, electrostatic discharge (ESD) has a high risk of damage during the component carrier manufacturing process. Conventionally, component carriers (preforms) in production may be safely stored in lockers that are protected from ESD events. However, component carriers in production need to be handled by an operator such as a human worker or robot. According to the ANSI ESD S20.20/IEC61340-5-1 standard for electrostatic control requirements, the operator' S electrostatic voltage should be below ±100V to avoid the risk of causing ESD. However, the electrostatic voltage of the operator is not estimated, and thus ESD sensitive devices are often handled accidentally by an electrostatically charged operator, thereby damaging or even destroying them. In addition, since the environment of the component carrier manufacturing facility is full of chemicals, the lockers themselves may rust and create foreign objects, which may also damage the component carriers in production. Opening the door of a locker in environments where the component carrier is busy in production may further increase the risk of injury to the working human operator. Furthermore, in large component carrier manufacturing facilities, a large number of lockers may be used, and therefore, there may be many lockers lost or the contents of the lockers may not be identifiable without opening the lockers (which increases the risk of ESD damage).

In the context of this document, the term "electrostatic discharge" (ESD) may denote a sudden current flow between two charged objects. When different charged objects are brought close to each other, ESD may occur. In the context of component carrier manufacturing, ESD may be considered an undesirable effect that may damage or destroy the component carrier (in manufacturing). When subjected to the high voltages of ESD, they may be permanently damaged. Thus, component carrier manufacturers can use measures to prevent charging and antistatic equipment to create an electrostatic protection zone (EPA) that is substantially free of electrostatic charges. In particular, sensitive products may be protected by ESD shielding. ESD shielding or "manner of ESD shielding" may refer to devices or measures that reduce, suppress, or otherwise prevent electrostatic discharge. Thus, in the context of this document, the term "ESD-shielded" may refer to any measure that reduces/prevents ESD, for example by applying antistatic materials and antistatic agents. In this document, the terms "ESD-shielded" and "antistatic" may be used synonymously.
In the context of this document, the term "transport device" may denote any device adapted to store a component carrier in an ESD shielded manner (in a cavity). The transport device may include a locking element to securely lock the ESD sensitive product in the ESD shielded cavity. Preferably, the wall surrounding the storage volume and the locking element comprises an ESD shielding/antistatic material. In an embodiment, the transport device is movable, i.e. wheels are used. The component carrier manufacturing facility may include a plurality of such transport devices, each of which stores a different component carrier at a different stage of production.
In the context of this document, the term "wireless communication device" may denote any device adapted to communicate wirelessly (with another wireless communication device). For example, data (information) between a wireless communication device that communicates (transmits/receives) and another wireless communication device may be communicated via 4G, 5G, wifi (802.11 p), radio Frequency (RF), RFID, NFC, or DSRC (dedicated short range communication). The wireless communication device may be configured as a receiver, transmitter or transceiver. The wireless communication device may also be configured to communicate with wireless communication devices (external devices) of other transportation devices. Further, the wireless communication device may be configured to communicate with a control device (external device) of the transportation device organization system. Additionally or alternatively, the wireless communication device may be integrated in a wireless communication network and/or an internet of things (IoT) system.
In the context of this document, the term "wireless communication network" may refer to a computer network that uses wireless data connections between network nodes (e.g., wireless communication devices). In an example, the network may be configured as a Wireless Local Area Network (WLAN) that links two or more devices over a short distance using a wireless distribution method (e.g., via providing a connection through an access point for internet access). In an example, the IEEE 802.11WLAN standard (Wi-Fi) may be used. In the network, information indicative of the transportation device(s) may be stored and retrieved again. For example, the electrostatic test (device) may be connected to a network and the (individual identity related) test results for different operators may be stored in the network or in a network related memory. In addition, the transport device may upload its current location and/or its current load to the network or network-related memory. These data may be stored, for example, in a memory (of the control device). By combining information in the network, the transportation device can be efficiently organized.
The wireless communication device and/or the further wireless communication device comprises 4G and/or 5G functionality. In the context of this document, the term "4G and/or 5G functionality" may refer to known wireless system standards. 4G (or LTE) is an established standard, while 5G is a standardized forthcoming technology and is likely to be fully established in the near future. The wireless communication device may also be suitable for future developments such as 6G.
The wireless communication device may also conform to WiFi standards such as 2.4GHz, 5GHz, and 60GHz. The electronic device may for example comprise a so-called wireless combination (integrated with WiFi, bluetooth, GPS … …), radio Frequency Front End (RFFE) or Low Power Wide Area (LPWA) network module.
The wireless communication device and/or the further wireless communication device may comprise an antenna. In the context of this document, the term "antenna" may particularly denote an element connected to a receiver or a transmitter, for example by a transmission line. Thus, an antenna may be represented as an electrical component that converts electrical energy into radio waves (and vice versa). The antenna may be used with a controller (e.g., a control chip) such as a radio transmitter and/or a radio receiver. In transmission, the radio transmitter may supply an electric current oscillating at radio frequency (i.e., high-frequency alternating current) to the antenna, and the antenna may radiate energy from the electric current as electromagnetic waves (particularly radio waves). In the receive mode, the antenna may intercept some of the electromagnetic wave power to provide a small voltage, which may be applied, for example, to a receiver for amplification. In an embodiment, the antenna may be configured as a receiver antenna, a transmitter antenna, or a transceiver (i.e., transmitter and receiver) antenna. In one example, the antenna may be configured as a single antenna. In another example, the antennas may be configured as an (adhesive, embedded) antenna array.
The wireless communication device and/or the further wireless communication device may comprise a radar. In the context of this document, the term "radar" may refer to object detection that uses electromagnetic waves to determine a distance, angle, or speed of one or more objects. Radar devices may include transmitters that transmit electromagnetic waves (e.g., in the radio or microwave range). Electromagnetic waves from the transmitter are reflected from the object and returned to the receiver. Thus, one antenna structure may be used for transmission and reception. Further, a processor, such as an electronic component, may be used to determine characteristics of objects, such as position and velocity, based on the received electromagnetic waves. According to further embodiments, the described component carrier may be applied in the context of radar applications. Especially for industrial radar applications. Radar applications can be performed in the following frequency ranges: 65GHz and higher, in medium or long distances-today typically from 77GHz to 81GHz, but can be increased to 90GHz and in the long term even further with the increase of technical capabilities. Radar applications may be performed in the millimeter wave range, in particular, for industrial applications (e.g., level indicators). In these examples, the antenna structure and electronic components (e.g., HF components for radar applications) may advantageously be arranged in spatial proximity without undesirable parasitics occurring.
In the context of this document, the term "component carrier" may particularly denote any support structure capable of accommodating one or more components thereon and/or therein to provide mechanical support and/or electrical connection. In other words, the component carrier may be configured as a mechanical and/or electrical carrier for the component. In particular, the component carrier may be one of a printed circuit board, an organic interposer and an IC (integrated circuit) substrate. The component carrier may also be a hybrid plate of a different type in combination with a component carrier of the type described above.
In an embodiment, the component carrier comprises at least one electrically insulating layer structure and at least one (layer) stack of electrically conductive layer structures. For example, the component carrier may be a laminate of the mentioned electrically insulating layer structure(s) and electrically conductive layer structure(s), which is formed in particular by the application of mechanical pressure and/or thermal energy. The mentioned stack may provide a plate-shaped component carrier that is capable of providing a large mounting surface for further components and that is still very thin and compact. The term "layer structure" may particularly denote a continuous layer, a patterned layer or a plurality of discontinuous islands in a common plane.
In the context of this document, the term "component carrier preform" may particularly denote a panel comprising a plurality of semi-finished component carrier products (as described above). For example, the panel may be later separated (singulated) into a plurality of (finished) component carriers. In another example, the component carrier preform may be a single semi-finished component carrier.
According to an exemplary embodiment, the invention can be based on the idea that component carriers and/or component carrier preforms can be stored and transported in an efficient and safe manner in a component carrier manufacturing facility, when an ESD shielding mobile transport device is applied, comprising: i) A storage volume of the ESD shield that can be safely closed by the locking element, and ii) a wireless communication device that communicates information about the transportation device with an external device. Thus, only authorized operators without ESD risk can open the transport device and handle the interior component carriers. The external device may be another transportation device, a control device and/or a network. Thus, the transport device may (automatically) receive relevant information about the authorization status of the operator. Further, the transport device (or devices) may be effectively organized and coordinated during the component carrier manufacturing process using the wireless communication device(s).
Conventionally, it is not possible to verify whether the operator is indeed free of ESD risk. Testing is only possible at a particular test station and carelessly forgets to test that its operator has opened the ESD shielded locker and damaged/destroyed the contents. These drawbacks have been overcome by the transport device which is only turned on when authorization information (from the electrostatic test) is received wirelessly.
Furthermore, conventionally, in large facilities, ESD shielded lockers are often lost or cannot identify any information about their loading without opening them. These drawbacks are also overcome in that the described transport device can be positioned and coordinated by means of a wireless communication device and/or a wireless communication network, in particular using a control device, using information related to the transport device.
Exemplary embodiments
According to an exemplary embodiment, the wireless communication device is coupled with the locking control unit and the wireless communication device is configured to control the locking control unit (or trigger a reaction of the locking control unit) based on information related to the transportation device. This may provide the following advantages: since the opening/closing of the locking element depends on the information received by the wireless communication device, ESD-sensitive contents of the transportation device can be effectively protected.
For example, the information related to the transport device includes information about the authorized status of the operator, particularly if the operator passes the electrostatic test. In this way, the wireless communication device may receive authorization information from the electrostatic test device (over the network) and then the wireless communication device may communicate a command related to the test to the lock control unit to either "on" or "keep off".
According to further exemplary embodiments, the external device is at least one of: at least one additional mobile ESD-shielded transport device, control device, internet of things (IoT) application. This may provide the following advantages: transport equipment is widely connected within component carrier manufacturing facilities so that information can be coordinated efficiently.
The term "IoT" in this context may refer to a network of physical objects (things) as follows: the physical object (thing) includes: sensors, software, and other technologies for connecting and exchanging data with other devices and systems over a network (internet). In other words, the term "IoT application" may refer to a particularly complex wireless communication network. The component carrier manufacturing facility may be at least partially equipped with an IoT application in which a large number of devices are interconnected. The transport device or multiple transport devices may be integrated into such IoT applications. In an example, the static electricity test device and/or the control device may also be integrated in the IoT application.
According to a further exemplary embodiment, the information related to the transport device comprises information about the positioning of the transport device (in particular in a component carrier manufacturing facility). This may provide the following advantages: in particular by retrieving this information from the wireless communication network, the location of the particular transportation device (and its contents) can be easily found. Thus, the known disadvantages of ESD shielded lockers being lost in complex component carrier manufacturing facilities are overcome.
According to a further exemplary embodiment, the transport device-related information comprises information about the component carriers and/or component carrier preforms to be stored in the storage volume. This may provide the following advantages: in particular by retrieving this information from the wireless communication network, the positioning of a specific component carrier (preform) at a specific processing step (or facility level) can be easily found.
Furthermore, it is possible to identify which transport device comprises which component carrier (preform) without having to open the transport device (which would create unnecessary ESD risk). Thus, the known disadvantage that certain component carriers are lost in complex component carrier manufacturing facilities and ESD shielded lockers must be opened to verify their contents can be overcome.
According to a further exemplary embodiment, the information related to the transport device comprises information about the authorization status of the specific operator, in particular the electrostatic test result. This may provide the following advantages: in particular, based on recent static test results, authorization information can be provided to the transport device (and the lock control unit) in a dynamic (periodically updated) manner.
According to further exemplary embodiments, the locking element comprises a locking door, such as a rolling door (roller shutter gate) and/or a telescoping sliding door. Conventional ESD shielded lockers include doors that open in a window-like manner, thereby occupying space in a space-constrained manufacturing environment. This increases the risk of damage to the operator. The locking door, configured as a rolling shutter door and/or a telescoping sliding door, overcomes these problems and provides additional safety advantages for the work environment.
According to further exemplary embodiments, the transportation device comprises at least one of an ESD shielding material, an antistatic material, an ESD shielding agent, an antistatic agent, an ESD or antistatic coating, an anti-rust coating. In particular, the ESD-sensitive contents of the transport device are thereby protected from ESD. Furthermore, rust of transportation equipment (which can be used in a component carrier manufacturing facility in which a large amount of chemicals are used) can be effectively suppressed.
According to a further exemplary embodiment, the transport device further comprises a token reader coupled to the lock control unit for analysing the operator's token, in particular a smart card. Based on the results of the analysis, the token reader is further configured to provide information to the lock control unit that the operator is authorized or that the operator is unauthorized. The token reader may advantageously be applied as an additional authorization mechanism that interacts with the wireless communication device (which is coupled to the lock control unit).
The token reader may be disposed external to the transport device and may be configured as a card reader (e.g., RFID or NFC). The operator may swipe his personal (utility) card over the card reader, and the card reader may identify the personal identity of the operator. This may increase security, as only a specific operator may be allowed to open a specific transportation device. Thus, even if the operator is authorized from an electrostatic perspective, access can still be denied from a personal identity-based perspective.
According to a further exemplary embodiment, the transport device further comprises a (self) positioning device configured to self-position the transport device and to store the positioning result as information related to the transport device. In this way, the transport device can locate itself and communicate the information to the network (e.g., to the control device) so that organization/coordination can be accomplished efficiently.
The (self) positioning device may comprise, for example, one of the following: distance sensor, speed sensor, positioning sensor, camera, radar, ultrasound function, GPS (global positioning system), differential GNSS, SLAM (simultaneous positioning and mapping) function, GPR (ground penetrating radar). In principle, the positioning device may be any kind of sensor device that enables the transport device to position itself within the component carrier manufacturing facility (in particular with respect to different levels of the facility).
According to an exemplary embodiment of the present invention, the transport apparatus further includes: an output element coupled to the storage volume and configured to automatically output the at least one component carrier and/or the at least one component carrier preform from the storage volume in an ESD-shielded manner. This may provide the following advantages: ESD sensitive contents are even more safely protected because the operator does not have to manually retrieve the component carrier (preform) from the storage volume.
The output element may comprise any mechanism suitable for automatically delivering the contents of the transport device. For example, the output element may comprise a drawer (in particular L-shaped) that automatically pushes out the storage volume (see fig. 2).
According to a further exemplary embodiment, the storage volume comprises a plurality of slots for storing a plurality of component carriers and/or component carrier preforms. Thus, the content of the transport device can be well organized and the desired object can be retrieved in an easy and safe manner.
According to further exemplary embodiments, the operator is a human and/or a transport robot. While the operator is a human facility worker in many examples, it may be any kind of robot configured to handle component carriers (preforms) during manufacturing. The robot may also have to perform an electrostatic test before being authorized to open the locking element of the transport device.
According to further exemplary embodiments, the transport apparatus further comprises a display configured to provide information related to the transport apparatus to an operator of the transport apparatus. The information relating to the transport device is, for example, an indication of the component carrier and/or the component carrier preform to be stored in the storage volume. This may provide the following advantages: the operator can easily find the positioning of a specific component carrier (preform) at a specific processing step without having to open the transport device (which would create unnecessary ESD risk). Thus, the known disadvantage that a specific component carrier is lost in a complex component carrier manufacturing facility and that an ESD shielded locker must be opened to verify its contents can be overcome.
According to a further exemplary embodiment, the transport apparatus further comprises a mechanical lock element for receiving the primary key and coupled to the locking element, wherein the mechanical lock element is configured to unlock the lock element upon receiving the primary key. This measure provides the advantage of additional security. For example, in an emergency, even if an operator is unauthorized, it may be critical to open the locking element. The mechanical lock may be part of the lock control unit or may be arranged separately from the lock control unit.
According to a further exemplary embodiment, the locking control unit is configured to automatically close the locking element after a predefined period of time. This aspect provides an additional safety measure for the ESD sensitive transport equipment contents.
According to a further exemplary embodiment, the transport device comprises at least one movable element, in particular a wheel, for moving the transport device manually or automatically within the component carrier manufacturing facility. In particular, the movable element is coupled to the storage volume via a mounting structure such that the storage volume is positioned at an elevated height that is substantially touchable by a standing human operator. This may provide the following advantages: the described transport device is easy to handle and in particular user friendly.
According to a further exemplary embodiment, the control device comprises a memory for storing information related to the transport device comprising at least one of the following: the positioning of the plurality of transport devices, the identity of authorized and/or unauthorized operators, the transport direction of the component carrier and/or component carrier preform in the component carrier manufacturing facility.
According to a further exemplary embodiment, the control device is configured to coordinate a plurality of transport devices. In particular, coordinating includes at least one of: coordination of positioning, coordination of authorized and unauthorized operators, coordination of transport directions of component carriers and/or component carrier preforms in component carrier manufacturing facilities.
This may provide the following advantages: even in a large component carrier manufacturing apparatus, a plurality of (large) transportation apparatuses can be organized and coordinated. The control device may be any processor or processors configured to receive, store, and control information received from the transportation device and/or the wireless network. The control device may be handled by a human operator or may be operated automatically. The control device may also include AI functionality (e.g., a neural network) that may be trained based on human decisions. The control device may be coupled to the wireless communication network and/or the IoT application.
According to further exemplary embodiments, the transport equipment organization system is coupled to an internet of things (IoT) application, in particular, wherein the IoT application comprises an Artificial Intelligence (AI) algorithm (see description above).
According to further exemplary embodiments, further comprising: presenting the operator's token to a token analyzer of the transport device; analyzing the token; and based on the analysis result: the operator is further authorized or not authorized to open the locking element of the transport device (see description of tokens above).
According to a further exemplary embodiment, the token is an indication of the operator and the identity of the operator is coupled to the test results stored in the wireless communication network. In this way, the token may be used to identify the identity of the operator, which may then be used to retrieve test results from the network. Thus, the transport device can be handled in a safe, automated and user-friendly manner.
According to a further exemplary embodiment, in case the operator is authorized, the method further comprises automatically opening the locking element and/or manually opening the locking element (see description above) a.
According to further exemplary embodiments, the static test comprises testing a specific part of the operator, in particular the shoe or the wrist. This may provide the following advantages: established electrostatic testing methods can be applied so that the method can be implemented directly into existing facilities. Preferably, the electrostatic test device(s) may be coupled to a facility wireless communication network to upload test results. Further, the uploaded test results may be coupled with a corresponding operator (e.g., personal identity).
According to a further exemplary embodiment, the movable element comprises a locking function. For example, the wheels may be automatically locked. This may provide the following advantages: the safety increases even when, for example, the locking element should not be turned off or the ESD shielded device is charged.
According to further exemplary embodiments, the ESD shielded transport apparatus includes an energy storage element (e.g., a battery and/or a storage cell) and an automatic charging function. For example, the device is configured to automatically charge the energy storage element (and automatically drive to a charging station) when the power state of the energy storage element is low (e.g., below 10%). This may provide the following advantages: the power supply of the device is robust and accordingly the device operates in a very secure manner.
In an embodiment, the component carrier is shaped as a plate. This contributes to a compact design, wherein the component carrier is still providing a larger base for the components mounted thereon. Further, in particular, for example, a bare die as an example of an embedded electronic component, due to its small thickness, can be conveniently embedded in a thin plate such as a printed circuit board.
In an embodiment, the component carrier is configured as one of: printed circuit boards, substrates (particularly IC substrates) and interposers.
In the context of the present application, the term "printed circuit board" (PCB) may particularly denote a board-shaped component carrier, which is formed by laminating a number of electrically conductive layer structures with a number of electrically insulating layer structures (e.g. by applying pressure and/or by supplying thermal energy). As a preferred material for PCB technology, the electrically conductive layer structure is made of copper, whereas the electrically insulating layer structure may comprise resin and/or glass fibres, so-called prepreg or FR4 material. The various conductive layer structures may be connected to each other in a desired manner by: forming a through hole through the laminate, for example by laser drilling or mechanical drilling; and filling them with a conductive material (particularly copper) to form a via as a via connection. In addition to one or more components that may be embedded in a printed circuit board, the printed circuit board is typically configured to house the one or more components on one or both opposing surfaces of the board-shaped printed circuit board. These components may be attached to the respective major surfaces by welding. The dielectric portion of the PCB may be composed of a resin with reinforcing fibers (e.g., glass fibers).
In the context of the present application, the term "substrate" may particularly denote a small component carrier. The substrate may be a relatively small component carrier relative to the PCB on which one or more components may be mounted, and which may act as a connection medium between the chip(s) and another PCB. For example, the substrate may have substantially the same dimensions as the components to be mounted thereon (particularly electronic components) (e.g., in the case of Chip Scale Packages (CSPs)). More specifically, a substrate may be understood as a carrier for an electrical connection or electrical network as well as a component carrier comparable to a Printed Circuit Board (PCB), but having a rather high density in laterally and/or vertically arranged connections. The lateral connection may be, for example, a conductive path, while the vertical connection may be, for example, a borehole. These lateral and/or vertical connections are arranged within the substrate and may be used to provide electrical, thermal and/or mechanical connection of packaged or unpackaged components, such as bare dies, in particular an IC chip, to a printed circuit board or an intermediate printed circuit board. Thus, the term "substrate" also includes "IC substrate". The dielectric portion of the substrate may be composed of a resin with reinforcing particles, such as reinforcing spheres, particularly glass spheres.
The substrate or interposer may include or consist of: at least one layer of glass, silicon (Si) or photoimageable or dry etchable organic material, such as an epoxy-based laminate material (such as an epoxy-based laminate film) or a polymer compound, such as a polyimide, polybenzoxazole or benzocyclobutene functionalized polymer.
In an embodiment, the at least one electrically insulating layer structure comprises at least one of: resins (such as reinforced or non-reinforced resins, for example epoxy resins or bismaleimide-triazine resins), cyanate resins, polyphenyl derivatives, glass (in particular glass fibers, laminated glass, glass-like materials), prepreg materials (such as FR-4 or FR-5), polyimides, polyamides, liquid Crystal Polymers (LCP), epoxy-based laminate films, polytetrafluoroethylene (PTFE),) Ceramics and metal oxides. Reinforcing structures made of glass (multiple layer glass), such as mesh, fibers or spheres, for example, may also be used. While prepregs, particularly FR4, are generally preferred for rigid PCBs, other materials, particularly epoxy-based laminate films or photoimageable dielectric materials, may also be used. For high frequency applications, high frequency materials such as polytetrafluoroethylene, liquid crystal polymers and/or cyanate ester resins, low temperature co-fired ceramics (LTCC), or other low, very low or ultra low DK materials may be implemented in the component carrier as an electrically insulating layer structure.
In an embodiment, the at least one conductive layer structure comprises at least one of: copper, aluminum, nickel, silver, gold, palladium, magnesium, and tungsten. Although copper is generally preferred, other materials or coated versions thereof are also possible, particularly coated with a superconducting material such as graphene.
The at least one (electronic) component may be selected from: a non-conductive inlay, a conductive inlay (e.g., a metal inlay, preferably comprising copper or aluminum), a heat transfer unit (e.g., a heat pipe), a light guiding element (e.g., an optical waveguide or a light guiding connection), an optical element (e.g., a lens), a bridge, an energy harvesting unit, an electronic component, or a combination thereof. For example, the component may be an active electronic component, a passive electronic component, an electronic chip, a storage device (e.g., DRAM or other data storage), a filter, an integrated circuit, a signal processing component, a power management component, an optoelectronic interface element, a light emitting diode, an optoelectronic coupler, a voltage converter (e.g., a DC/DC converter or an AC/DC converter), a cryptographic component, a transmitter and/or receiver, an electromechanical converter, a sensor, an actuator, a microelectromechanical system (MEMS), a microprocessor, a capacitor, a resistor, an inductance, a battery, a switch, a camera, an antenna, a logic chip, and an energy harvesting unit. However, other components may be embedded in the component carrier. For example, a magnetic element may be used as the member. Such magnetic elements may be permanent magnetic elements (such as ferromagnetic elements, antiferromagnetic elements, multiferroic elements or ferrimagnetic elements, e.g. ferrite cores) or may be paramagnetic elements. However, the component may also be a substrate, interposer or another component carrier, for example in a board-to-board configuration. The component may be surface mounted on the component carrier and/or may be embedded within it. In addition, other components, particularly those that generate and emit electromagnetic radiation and/or are sensitive to electromagnetic radiation propagating from the environment, may also be used as components.
In one embodiment, the component carrier is a laminate type component carrier. In such embodiments, the component carrier is a composite of multiple layers of structures that are stacked and joined together by the application of pressure and/or heat.
After the treatment of the inner layer structure of the component carrier, one or both opposite main surfaces of the treated layer structure may be symmetrically or asymmetrically covered (in particular by lamination) with one or more further electrically insulating layer structures and/or electrically conductive layer structures. In other words, lamination may continue until the desired number of layers is achieved.
After the formation of the stack of electrically insulating and electrically conductive layer structures is completed, the resulting layer structure or component carrier may be surface treated.
In particular, an electrically insulating solder resist may be applied to one or both opposite major surfaces of the layer stack or component carrier. For example, a solder resist, for example, can be formed over the entire major surface and then the solder resist layer patterned to expose one or more conductive surface portions that will serve to electrically couple the component carrier to the electronic element periphery. Surface portions of the component carrier, particularly surface portions containing copper, which remain covered with the solder resist, can be effectively protected from oxidation or corrosion.
In terms of surface treatment, surface finish may also be selectively applied to the exposed conductive surface portions of the component carrier. Such surface finish may be a conductive covering material on exposed conductive layer structures (such as pads, conductive traces, etc., particularly comprising or consisting of copper) on the surface of the component carrier. If such exposed conductive layer structures are not protected, the exposed conductive component carrier material (particularly copper) may oxidize, thereby reducing the reliability of the component carrier. The surface finish may then be formed, for example, as an interface between a surface mounted component and a component carrier. The surface modification has the function of protecting the exposed conductive layer structure, in particular the copper circuit, and enables the joining process with one or more components, for example by soldering. Examples of suitable materials for surface modification are Organic Solderability Preservative (OSP), electroless Nickel Immersion Gold (ENIG), gold (especially hard gold), electroless tin, nickel gold, nickel palladium, ENIPIG (electroless nickel immersion palladium immersion gold), and the like.

Detailed Description
The exemplary embodiments will be described in further detail before referring to the accompanying drawings, which will be summarized based on some basic considerations of having developed exemplary embodiments of the present invention.
According to an exemplary embodiment, an ESD cart electronic lock (locking control unit) of a transport device is interconnected with a personal static system (wireless communication network) in which personal static tests (e.g. shoes, hand rings, body resistance) are qualified (according to ANSI ESD S20.20 resistance requirement: personnel hand ring system resistance: 1.0 x 10 6 To 3.5 x 10 7 Personnel sole system resistor 10 5 To 10 9 The tribostatic voltage is between-100V and +100V) and the ESD cart shield (locking element) can be opened after the card (token) has been checked. When the operator passes the electrostatic test and provides the card, the electronic lock will display the light and activate the unlock button (lock control unit) to open the top cover (locking element) of the transport device.
According to an exemplary embodiment, the transport device may be implemented by: in order to avoid the influence of the external electric field on the product (component carrier), the cavity (storage volume) conductor is used to cover the external electric field, so that the internal product is not influenced by the external electric field, and the damage caused by static electricity is effectively avoided. The design of the shielding door (locking element) meets the space requirement and is fixed on the trolley (transportation equipment), so that the risk of injury to personnel is effectively avoided. When the roller shutter door lock (lock control unit) is opened, the product can be picked up and placed. The inner L-shaped frame (output member) can be moved after the rolling door is pushed up into place.
According to further exemplary embodiments, the potential Foreign Matter (FM) problem caused by a telescoping sliding door may be overcome by: i) The rail material is based on current in-plant upper and lower trigger roller materials (POM) and rail production can be easily replaced, and/or ii) the rail can also use 903 rigid material and the power door uses sealed bearings as contact points which can effectively reduce friction surfaces and avoid FM problems.
Fig. 1 illustrates a mobile electrostatic discharge (ESD) shielding transport apparatus 100 for a component carrier 110 and/or a component carrier preform according to an example embodiment. The transport device 100 comprises a storage volume 120 in the container, which is configured for storing the component carrier 110 and/or the component carrier preform in an ESD-shielded manner. The transport apparatus 100 includes ESD-shielding and/or antistatic materials and rust inhibitive coatings. The storage volume 120 is coupled to the movable element 170 (wheels, in particular wheels that can be locked automatically) via a mounting structure 175, such that the storage volume 120 is positioned at an elevated height that can be reached by a vertically standing human operator 400. Using wheels 170, the transport apparatus 100 may be manually or automatically moved within the component carrier manufacturing facility 500.
The transport apparatus 100 further comprises a locking element 130 for safely locking the storage volume 120. The locking element 130 is a telescopic sliding door which in the closed state protects the interior 120 of the transport device 100 from electrostatic discharge. In addition, the transport apparatus 100 includes a lock control unit 140, and the lock control unit 140 is coupled with the lock member 130 and configured to control opening and closing of the lock member 130. The locking element status indicator 141 also indicates the status of the telescoping sliding door 130. The lock control unit 140 may be configured to lock only, and the locking element 130 must be manually opened. Alternatively, the locking device 140 comprises a mechanism for automatically opening the locking element 130. The lock control unit 140 may be configured to automatically close the locking element 130 after a predetermined period of time. In the operating state of the transport device 100, the component carrier 110 (preform) is located in the storage volume 120 and the locking element 130 is closed. The lock control unit 140 triggers the opening of the locking element 130 only when the operator 400 (human or transport robot) is authorized, and leaves the locking element 130 closed when the operator 400 is unauthorized.
The transportation device 100 further comprises a token reader 135, which token reader 135 is a smart card reader/writer coupled to the lock control unit 140 for analysing tokens for smart cards (e.g. personal facility IDs) of the operator 400. Based on the results of the analysis, the token reader 135 is further configured to provide information to the lock control unit 140 that the operator 400 is authorized or that the operator 400 is unauthorized.
For emergency situations, the transport apparatus 100 includes a mechanical lock element 180 for receiving a primary key, the mechanical lock element 180 being coupled to the locking element 130 such that the locking element 130 may be opened using the primary key. The transportation device 100 may further include a positioning device (e.g., a GPS device or an ultrasound device, not shown) configured to self-position the transportation device 100 and store the positioning results as information (e.g., in a wireless network) related to the transportation device 100.
The transportation device 100 further comprises a wireless communication device 150, which wireless communication device 150 is configured to communicate with external devices 100a-100c, 210 (see fig. 3 below) about information related to the transportation device 100. The information related to the transport apparatus 100 includes information about at least one of the component carriers 110 and/or component carrier preforms to be stored in the storage volume 120, about the positioning of the transport apparatus 100 in the component carrier manufacturing facility, and/or about the authorized status of the particular operator 400.
The wireless communication device 150 is coupled with the lock control unit 140 such that the wireless communication device 150 can control the lock control unit 140 based on information (and, for example, trigger on/off) related to the transportation device 100.
ESD shielded transport apparatus 100 includes a battery/accumulator (not shown) so that it can be freely moved in component carrier manufacturing facility 500 without cabling.
