A PCB test jig is essentially a special tool used to check if a printed circuit board (PCB), which is a piece of technology inside devices like phones and computers, is working properly. Imagine it as a sort of “mold” that the PCB fits into. Once the board is placed into this mold, the jig can check all the parts of the board to make sure they’re all doing what they’re supposed to do.
The jig has tiny, spring-loaded pins called pogo pins that touch specific points on the circuit board. When these pins make contact, they can test the electrical connections by sending signals through the board and checking the responses. This ensures that every part of the board is correctly made and connected, and it helps find any mistakes or faults before the board goes into a final product.
In simpler terms, a PCB test jig is like a doctor’s check-up for a circuit board, making sure everything is healthy and ready to go before it starts its job in an electronic device.
