Description

System for reduction of energy and fraction defective in the production of PCB based ubiquitous sensor network}

The present invention relates to a system for reducing energy and defect rate in the production of a ubiquitous sensor network (USN) based printed circuit board (PCB), and more particularly, to obtain environmental information of each process during PCB production. The present invention relates to a system for reducing energy and defect rate in the production of printed circuit boards based on ubiquitous sensor networks that can provide process environment information that is optimal for PCB production by cumulative analysis.

In general, the process of producing a printed circuit board (PCB) may be different for each PCB production company, but in general, the disc cutting process using the cutting machine, the inner layer working process, the lamination process, the chamfering process using chamfering, tapping stocking (tapping) stacking) process, drill process for hole processing, high pressure washing process using centuries, DESMEAR process, panel plating process, pickling process to roughen copper foil surface, adhesion process, pattern exposure process, D / F development process, etching process, D / F peeling process, PSR front treatment process, PSR printing process, PSR drying process, PSR exposure process, PSR developing process, MARKING process for printing and drying invariant ink, surface treatment process, ROUTER process, V-CUT process, water washing PCB is manufactured by performing inspection process for process, BBT process and quality control.

In each process, the PCB to be produced is moved to each process position through the conveyor.

In this general PCB production process, the defect rate and energy use rate of PCB production vary according to the environmental information (speed, power, time, temperature, water usage, etc.) provided for each process. Rather than monitoring the system, the production status was determined based on the total amount of energy used and the total power consumption. However, the total amount of energy used and the total power consumption alone are not enough to optimally analyze PCB production efficiency. For example, a large number of environments are provided in the PCB production process, and it is difficult to analyze the PCB production efficiency simply by the total amount of energy and the power consumption without analyzing the environment.

Therefore, various methods have been proposed to increase the production efficiency by monitoring the environmental information required for a specific production process and adjusting the energy required based on the monitoring result, and one of them is registered in the Korean Patent Office, Republic of Korea Patent Publication No. 10-0918923 (Information: Smart Energy Control Device and Method in Ubiquitous Center Network Environment) (hereinafter, abbreviated as "Prior Art").

It is set. It is a compound word of TCP and IP that plays the most important role among internet protocols. It is a communication protocol that is the center of Internet operation. In charge.

Normally, IP moves data exactly from one place to another, while TCP controls the flow of data so that the entire data can be transmitted well and ensures that it can successfully arrive at the other computer. TCP / IP is an open protocol standard that can be used independently of specific hardware or operating systems. It is also a communication protocol used to connect computers with different systems on the Internet and to transfer data, both locally and remotely.

TCP / IP consists of four layers: the application layer, the transport layer, the Internet layer, and the network interface layer. The application layer is responsible for receiving requests from user applications, converting them into appropriate messages, and delivering them to lower layers. The transport layer is a layer responsible for controlling errors such as checking a packet transmitted by an IP and requesting retransmission. Two types of protocols, TCP and UDP, are used. The Internet layer only considers the efficient delivery of packets received at the transport layer to the destination. Finally, the network interface layer is a layer that supports all standards and technical protocols without specifying a specific protocol. It is responsible for uploading and downloading frames onto a physical circuit.

The real time data manager 223 stores the environment information obtained from the tag manager 222 in real time in the database 224, and also stores the environment information provided after the analysis in the database 224. In this case, it is preferable to separately store the environmental information in the database 224 according to the type and process of the printed circuit board. For example, the type of the printed circuit board is PCB A, and the water usage information and turbidity information for the washing process of the PCB A are combined and stored.

The environmental application manager 225 analyzes the environment information provided from the tag manager 222 on the basis of the environment information for each printed circuit board type and process stored in the database 2240 to obtain optimal environment information for minimizing energy saving and defective rate. For example, the analysis generates optimal environmental information, such as prediction of water exchange time, based on temperature information of the lowest conveyor rate for each PCB type, temperature vs. conveyor speed, power consumption for defective rate, and detection of water consumption against turbidity. .

The optimal environmental information generated in this way is transferred to the environmental information providing unit 230, and the environmental information providing unit 230 displays the optimal environmental information transmitted on the screen, so that the user can easily optimize the printed circuit board by type and process. To obtain environmental information.

The user sees the optimum environmental information provided through the environmental information providing unit 230, and checks how much the conveyor speed is, and how much the temperature of the dryer is, the defect rate is minimum, and the maximum amount of energy is reduced while reducing energy. . Then, the optimum conveyor speed, temperature, etc. are manually set through the environment setting unit 240 which is an input device.

In this way, the conveyor speed and temperature setting values set by the user are transmitted to the environment information generation unit 220, and are transferred to the main controller controlling the production facility through the communication manager 221. Therefore, by controlling the corresponding equipment based on the conveyor speed information and the dryer temperature information transmitted from the main controller, the corresponding production equipment is controlled so that the defect rate is minimized and the yield is maximized.

According to the present invention can provide the user with the optimal energy information (environmental information) of the production process of the printed circuit board, the user reflects the optimal energy information, such as rational calculation of production costs, energy saving, rational control of energy by process By doing so, it is possible to achieve the effect of increased production and reduced cost.
