Description

  The present invention writes a predetermined information such as SPD to a non-volatile memory such as an EEPROM provided on a memory module board on which a plurality of semiconductor memories are mounted on the same circuit board, and also inspects the memory module board The present invention relates to a module substrate inspection system. The present invention also relates to a master substrate creating apparatus that is used in this inspection system and specialized to create a master substrate by writing predetermined information in the nonvolatile memory.

  As the memory module board, for example, a DIMM (Dual Inline Memory Module) used for a personal computer (hereinafter referred to as “personal computer”), a workstation, or the like is known. On this DIMM, an EEPROM (Electric Erasable Programmable ROM) which is a nonvolatile memory is mounted. In this EEPROM, SPD (Serial Presence Detection) data, which is information such as memory capacity, data width, control line, speed, etc. of the DIMM, is written by the manufacturer.

  In manufacturing a DIMM, the manufacturer writes SPD data in an EEPROM on the DIMM and inspects the DIMM. In this SPD data writing and DIMM inspection (hereinafter referred to as “substrate inspection etc.”), the SPD data writing to the EEPROM on the DIMM to be inspected, the assembly failure of the DIMM, the address fault, Inspect for signal noise defects.

  The SPD data written to the EEPROM varies depending on the type of DIMM. In recent years, the types of DIMMs have been steadily increasing due to technological development, and the types of SPDs are also increasing accordingly. Therefore, on the manufacturer side, SPD data corresponding to each DIMM is collectively managed by a personal computer in order to easily manage various kinds of SPDs.

  Among the inspection devices operated by the inspector for board inspection, etc., a computer capable of collectively managing SPD data corresponding to each DIMM and a DIMM that can be mounted and connected to the computer via a predetermined interface There is an inspection device (for example, TurboCATS II (trademark) manufactured by TRIAD SPECTRUM) configured with a DIMM mounting device. In this inspection apparatus, SPD data recorded on a recording medium such as a hard disk or a floppy disk of the computer can be transmitted to the DIMM mounting apparatus via the interface and written in the EEPROM on the DIMM. However, such an inspection apparatus is very expensive.

  On the other hand, there is an inexpensive inspection device (for example, TurboCATS I (trademark) manufactured by TRIAD SPECTRUM) that can be connected to a personal computer but can perform the same substrate inspection as the above-described expensive inspection device. This inspection apparatus can store seven types of SPD data in the apparatus. Therefore, it was possible to perform board inspection and the like for up to seven types of DIMMs.

  However, as described above, since the types of SPDs have increased in recent years, board inspections and the like are performed on more than seven types of DIMMs on an inspection line for performing board inspections using the above-described inexpensive inspection apparatus. I often want to. When various types of DIMMs are placed on the inspection line in this way, board inspection or the like cannot be performed only with the SPD stored in the inexpensive inspection apparatus. Therefore, for example, when performing board inspection or the like on the eighth type of DIMM, one of the SPD data already stored in the inspection apparatus is deleted, and the eighth SPD data corresponding to the DIMM is changed to the It must be stored in the inspection device, and then the substrate must be inspected.

  Conventionally, in the operation of storing new SPD data in the inexpensive inspection apparatus, the inspector looks at the paper on which the contents of the SPD are described and stores the SPD data in the inspection apparatus manually. For this reason, there is a problem that the work such as the substrate inspection is complicated and takes time, and the work efficiency is poor. In particular, this problem becomes more serious as the number of DIMMs on the inspection line increases.

  In addition, among the above-described inexpensive inspection apparatuses, there is a device that can download the SPD data from a master substrate that is a memory module substrate including a nonvolatile memory in which SPD data to be written to the inspection object is recorded. According to this, a DIMM that has been subjected to substrate inspection once in the past is stored as a master substrate, and by downloading SPD data from the master substrate, the same SPD data is not manually stored again in the inspection apparatus. You can do it. However, the DIMM itself used as a master board is expensive, and it is not preferable in terms of cost to prepare a master board for each type of SPD that will continue to increase, and it is complicated to store and manage a large number of master boards. is there. In some cases, there is a contract that the manufacturer will hand over all the DIMMs requested for manufacture to the customer. In that case, the DIMM cannot be stored as a master board.

  Further, when performing board inspection or the like using the above-described inexpensive inspection apparatus, when the SPD data is manually stored in the inspection apparatus as described above, an inspector who performs the operation may make a mistake input. There is also. If an error is input in this way, inspection of a substrate to be inspected or the like is performed based on the SPD data captured by the error input, so that the manually input SPD data and the source of the SPD data are used. It is very important to compare and check the SPD data in the personal computer. However, since the inspection apparatus cannot be connected to a personal computer, the comparison check operation cannot be performed by a mechanical operation such as a computing unit. For this reason, this comparison check work relies on a human work that the inspector performs visually. Therefore, there is a problem that the work efficiency is lower than that of mechanical work, and the reliability of checking manually input SPD data is also lower than that of mechanical work.

  The present invention has been made in view of the above problems, and the object of the present invention is to use a low-cost inspection device that cannot be connected to a personal computer or the like when performing a substrate inspection or the like of a memory module substrate. The operation of storing the specified information such as SPD can be easily performed in a short time compared to the conventional method, and there are few mistakes during the storage operation, and the work efficiency such as substrate inspection can be improved at low cost. Configurable memory module substrate inspection system, substrate mounting device and master substrate creation device used in the inspection system, and computer reading recording a program that causes a computer to function as means for configuring a write controller of the master substrate creation device It is to provide a possible recording medium.

A variety of memories to be inspected, including a writing control unit for writing information and an inspection control unit for inspecting a memory module substrate mounted on the substrate mounting unit in accordance with an inspection program recorded in the program memory unit Predetermined information corresponding to each memory module board is written to the nonvolatile memory on the module board and the memory module board is verified. In the memory module substrate inspection system that performs the above, the master substrate creation write control including the information memory unit, the write control unit, and an output interface unit for outputting predetermined information recorded in the information memory unit A device, an interface unit connected to the output interface unit, and the board mounting unit, and a predetermined information input via the interface unit is stored on a nonvolatile memory module board mounted on the board mounting unit. A substrate mounting device that transmits to a memory and an inspection device that includes the substrate mounting unit, the information memory unit, the program memory unit, the recording control unit, the write control unit, and the inspection control unit are separately provided. The master board creation write control apparatus is configured in the information memory section of the master board creation write control apparatus. The recorded predetermined information is output from the output interface unit under the control of the write control unit of the master substrate creation write control device, and becomes a master substrate mounted on the substrate mounting unit of the substrate mounting device. A master board is created by writing to a non-volatile memory on a memory module board, and the inspection apparatus stores predetermined information held by the master board mounted on the board mounting section of the inspection apparatus. Is recorded in the information memory unit of the inspection apparatus.

This inspection system does not use the above-described expensive inspection device, but uses a low-cost inspection device that cannot be connected to a personal computer or the like that can collectively manage each piece of SPD data according to the type of DIMM. A substrate inspection or the like is performed. Here, the personal computer or the like is used as a master substrate creation writing control device, and the writing control unit is realized by an arithmetic unit such as a CPU that executes a predetermined writing computer program.

In the inspection system according to the present invention, the predetermined information stored in the master substrate creation write control device is temporarily stored on the predetermined memory module substrate by the master substrate creation write control device and the substrate mounting device. A master substrate is created by writing into the non-volatile memory. Then, this master substrate is mounted on the substrate mounting portion of the inspection apparatus, and predetermined information in the nonvolatile memory on the master substrate is downloaded to the information memory section in the inspection device. In this way, since the predetermined information stored and managed by the master board creation writing control device is moved to the inspection device via the master substrate, compared with the conventional method of moving to the inspection device by manual input work. The work is simple and can be done in a short time, and there are almost no errors in storage in the inspection device.

  Further, the master substrate creation write control device and the substrate mounting device connected thereto write predetermined information in the master substrate creation write control device to a nonvolatile memory on a memory module substrate serving as a master substrate. It is specialized. In other words, since the inspection apparatus has a function of inspecting the memory module substrate for an assembly failure or the like, the master substrate creation write control device itself and the substrate mounting device itself perform the substrate inspection. It is not necessary to provide a function to be performed, and only a function necessary for producing a master substrate is sufficient. Therefore, the master substrate creation writing control apparatus can be constituted by a general-purpose computer and a predetermined writing computer program. In addition, the substrate mounting device only needs to have a function of transmitting the predetermined information output from the master substrate creation writing control device to the nonvolatile memory on the memory module substrate mounted on the substrate mounting portion. Since the number of parts is small and the structure is simple, it can be manufactured at low cost. In addition, as an inspection apparatus that is another constituent element of the inspection system, a conventional inexpensive inspection apparatus (such as TurboCATS I (trademark) manufactured by TRIAD SPECTRUM) can be used.

  In this way, the inspection system, for example, installs a predetermined writing program in a general-purpose computer to configure the master board creation writing control apparatus, and manufactures or obtains the board mounting apparatus. Since it can be constructed simply by manufacturing or obtaining an inexpensive inspection device, the inspection system can be provided at low cost. In particular, for a user who already has an inexpensive inspection apparatus constituting the inspection system and who manages predetermined information collectively with a general-purpose computer, a predetermined writing program is installed in the general-purpose computer, and By simply manufacturing or obtaining the substrate mounting apparatus, it is possible to improve work efficiency without incurring costs.

At the time of inspection, an inspector appropriately selects and executes necessary ones from the stored inspection programs.

Hereinafter, the configuration and operation of the substrate mounting apparatus 10 and the inspection apparatus 20 constituting the inspection system, which is a characteristic part of the present invention, will be described.
FIG. 2 is a block diagram illustrating a schematic configuration of the substrate mounting apparatus 10, and FIG. 3 is a block diagram illustrating a schematic configuration of the inspection apparatus 20.

First, the configuration and operation of the substrate mounting apparatus 10 will be described.
In FIG. 2, the board mounting apparatus 10 includes a Centro connector 11 as an interface section that can be connected to the Centro connector of the personal computer 1 and other interface sections connected to the Centro connector 11 in a one-to-one manner inside the apparatus. The same type of Centro connector 12 is provided. The Centro connector 11 is connected to the Centro connector 12 by a flat cable, and the Centro connector 12 is connected to a printer device 8 which is an external device. With this configuration, even when the Centro connector for connecting the printer device of the personal computer 1 is used for the inspection system, communication between the personal computer and the printer device 8 can be maintained, and the personal computer can be used for other purposes. Is possible.

  The board mounting device 10 is provided with four sockets 13a, 13b, 13c, and 13d as board mounting portions on which DIMM 2 serving as a master board can be mounted. These sockets correspond to a first socket 13a corresponding to a 100-pin DIMM, a second socket 13b corresponding to a 184-pin DIMM, a third socket 13c corresponding to a 168-pin DIMM, and a 144-pin DIMM. The fourth socket 13d. Thereby, the board mounting apparatus 10 can be adapted to existing main DIMM formats. Here, the four sockets corresponding to the four types are provided. However, when it is necessary to support other types of DIMMs, sockets corresponding to the types may be provided.

  The board mounting device 10 is provided with an external connection connector 14 as another interface unit. The external connection connector 14 is provided on the back surface of the board mounting device 10 and is connected to the personal computer through the level changing unit 15 and the Centro connector 11 in the same manner as the sockets 13a, 13b, 13c, and 13d. ing. As shown in FIG. 4, the external connection connector 14 is connected to an external device 18 having sockets different from the four sockets 13a, 13b, 13c, and 13d provided in the apparatus main body. By providing this external connection connector 14, it is possible to create a new type of DIMM master board simply by preparing the other external device 18 without changing the design of the device body itself. . Further, instead of preparing the external device 18 having a socket corresponding to the new type of DIMM as described above, an IC clip or the like for directly connecting the terminal of the EEPROM and the terminal of the external connection connector 14 is externally provided. The device may be connected to the external connection connector.

Further, the board mounting apparatus 10 includes other external apparatuses or ICs that connect the signal level of the SPD data input from the Centro connector 11 to the sockets 13a, 13b, 13c, 13d and the external connector 14. A level changing unit 15 is provided at a signal level suitable for the EEPROM 3 on the DIMM 2 mounted on one of the clips. The level changing unit 15 changes the level of 5V SPD data input from the Centro connector 11 to 3.3V and outputs the level to each socket. Each data line extending from the level changing unit 15 is connected in parallel to each of the sockets 13a, 13b, 13c, 13d and the external connector 14, and the DIMM 2 is connected to one of these sockets. Then, the SPD data is written into the DIMM.
In the following description, a case where the fourth socket 13d corresponding to 144-pin DIMM 2 is used will be described.

  The DIMM 2 in which the SPD data is written in this way is used as a master substrate. However, if a write error is checked here, a mistake in storing the SPD data in the inspection apparatus 20 can be eliminated, and the substrate can be removed. It is possible to eliminate wasted time such as redoing the inspection. Therefore, in the present embodiment, a comparison application for comparing the SPD data stored in the hard disk with the SPD data written in the EEPROM 3 on the DIMM 2 to determine whether or not there is a writing error is stored in the personal computer 1. Installed. In this configuration, a comparison / determination unit is configured by a RAM that reads out and temporarily records a computer program of the comparison application and a CPU that executes the program.

  After the writing process by the writing application is completed, the comparison application first stores the SPD data written in the EEPROM 3 on the DIMM 2 mounted on the fourth socket 13d via the board mounting device 10. read out. Then, the SPD data is compared with the writing source SPD data stored in the hard disk. If the SPD is correctly written as a result of this comparison, “PASS” or the like is displayed on the monitor of the personal computer to inform the inspector that the writing has been performed normally. On the other hand, if the SPD is not correctly written, “FAIL” or the like is displayed on the monitor to notify the inspector that the writing has not been performed normally. In this case, the inspector takes measures by writing again or replacing the write target DIMM.

  When the master board is created in this way, the DIMM 2 is removed from the fourth socket 13d and carried to a place where the inspection device 20 is located, and the SPD is downloaded from the DIMM to the inspection device as will be described later.

Next, the configuration and operation of the inspection apparatus 20 shown in FIG. 3 will be described.
Similar to the fourth socket, the inspection device 20 is provided with a socket 21 corresponding to a 144-pin DIMM as a board mounting portion. The socket 21 is configured to be detachable from the inspection apparatus 20, and the socket can be exchanged according to the type of the DIMM to be inspected.

  The inspection device 20 includes an information memory unit 22 for storing SPD data, a program memory unit 23 for recording an inspection program to be executed by the inspection device, and a master substrate attached to the socket 21.

  The information memory unit 22 can store seven types of SPD data. The program memory unit 23 stores basic inspection programs set by default, and can store up to seven types of user-specific inspection programs. The information memory unit 22 and the program memory unit 23 may be formed of a single recording medium or separate recording media. If it is desired to manually input SPD data to the information memory unit 22, it can be input by operating the touch panel 9 shown in FIG. Similarly, when the user's original inspection program is stored in the program memory unit 23, the touch panel 9 is operated similarly.

  The recording control unit 24 records the SPD data written by the substrate mounting apparatus 10 in the information memory unit 22 in a predetermined format from the EEPROM 3 on the DIMM 2 which is the master substrate mounted on the socket 21. When seven types of SPD data are already stored in the information memory unit 22, a warning to that effect is given to the touch panel 9, and the inspector selects SPD data to be deleted from the seven types of SPD data. . Then, the recording control unit 24 erases the contents of the selected SPD data and writes new SPD data from the DIMM 2 in the data storage unit.

  The write control unit 25 extracts the SPD data selected by the examiner from the SPD data stored in the information memory unit 22 and outputs the SPD data to the socket 21. Then, the SPD data is written into the EEPROM 5 on the DIMM 4 to be inspected mounted on the socket 21.

  The inspection control unit 26 executes an inspection program selected by the inspector among the inspection programs stored in the program memory unit 23. This inspection program is used to detect open / short of address line, data line, DQM line, CS line, module control line, etc. on DIMM, and to detect open / short of each memory cell on DIMM. The various inspections designated by the inspection program are sequentially executed.

The inspection is performed as follows using the inspection system having the above configuration. Here, a case where the present inspection system is applied to an inspection line on which various types of DIMMs are mounted will be described.
First, a master substrate is created using the substrate mounting apparatus 10 in accordance with the type of DIMM on the inspection line. Then, the SPD data is downloaded from the corresponding master substrate to the inspection device 20 according to the type of DIMM flowing on the inspection line, and stored in the information memory unit 22. Whenever eight or more types of DIMMs flow, any SPD data stored in the information memory unit 22 is deleted and the corresponding SPD data is downloaded from the master board. The inspection is performed in this way, and when the inspection of the DIMM on the inspection line is finished, the master substrate is finally disposed and the inspection is finished. The master substrate may be discarded as it is, but may be stored for a predetermined period for the next use. If there is a contract to deliver all the DIMMs requested for manufacture and inspection to the customer, the master board is finally inspected and the master board is delivered together with the inspected board.

  As described above, according to the present embodiment, when using an inspection apparatus that cannot be connected to a personal computer, the SPD data stored and managed in the personal computer can be easily used without manually inputting SPD data. . In addition, as the inspection device, an inexpensive inspection device such as TurboCATS I (trademark) manufactured by TRIAD SPECTRUM can be used, and the substrate mounting device can be manufactured at a low cost. Can be built.

  Note that the inspection system of this embodiment may further include a read control unit that reads predetermined information in the EEPROM on the DIMM. When provided in the personal computer 1, this read control unit can be realized as a read application for reading predetermined information in the EEPROMs 3 and 5 on the DIMMs 2 and 4. In this configuration, the read control unit is configured by a RAM that reads and temporarily stores a computer program of the read application, a CPU that executes the program, and the like. Further, the substrate mounting apparatus 10 may be provided with a read control unit that reads SPD data recorded in the EEPROMs 3 and 5 on the DIMMs 2 and 4 and transmits them to the personal computer 1.

  By providing the reading control unit in the inspection system as described above, for example, even when predetermined information necessary for substrate inspection or the like is recorded in the EEPROM on the DIMM, the personal computer 1 can be sent. Therefore, even the SPD data obtained in this way can be stored and managed by the personal computer 1. It is also possible to select an arbitrary one from a large number of DIMMs 4 that have been inspected by the inspection device 20 and once read the SPD data written in the EEPROM 5. According to this, the SPD data in the EEPROM 5 of the DIMM 4 that has been inspected can be displayed in a predetermined format on the monitor of the personal computer or printed out using the printer device 8.
