Definition of Optoelectronic PCB
Photoelectric boards refer to PCBs used for LCD and other purposes, and have very strict requirements on size. A row of golden fingers is designed on the photoelectric board, and the area runs through the entire length of the PCB. Since it needs to be bonded with conductive glue and soft board during assembly, the alignment accuracy of each golden finger is very high during the bonding process. , Once slightly misaligned, it will cause poor functionality. Therefore, the position of each golden finger, that is, the dimensional stability of the length of the entire PCB is very demanding.
