[0002] CPCI board card is an open standard industrial bus system, originally developed by the German Electrical Engineering Association (EIPC), used to connect high-performance computers and various peripheral devices in embedded systems. CPCI aims to provide high-speed data transmission, low latency and high-reliability communication, widely used in aviation, aerospace, military, medical and automation control fields. CPCI supports modular slots, making it easy to replace and upgrade components, improving system flexibility. It also has a standardized interface, a unified electrical and mechanical interface that allows board cards produced by different manufacturers to be easily interchangeable. It also has low latency and high bandwidth characteristics, and through advanced serial transmission technologies such as LVDS or optical fiber, it realizes fast data transmission. Many CPCI board cards support hot swapping, allowing board cards to be replaced while the system is running, making maintenance easier.

[0003] In PCB packaging, the gold finger is a gold-plated column seen at the edge of the PCB connection, and the purpose of the gold finger is to connect auxiliary PCBs to the mainboard and various other devices that communicate through digital signals. The gold finger is composed of numerous golden conductive pads, and because its surface is gold-plated and the conductive pads are arranged like fingers, it is called "gold finger".

[0004] In actual use, in addition to the expiration of electronic components, the most common cause of damage to CPCI board cards is due to human factors, such as impact, scratching, and damage, which can cause CPCI board cards to malfunction, making it impossible to continue using the CPCI board card. Since the gold finger is packaged with the PCB, it cannot be replaced or repaired separately. Utility model content
