PCB circuit board manufacturer's board is only a light board, and there is nothing on it except the line. After the PCB manufacturer's vacuum packaging, SMT patch processing (components) test qualified, it can be considered as a real PCBA board.
At present, our company can produce layer 1-10 PCB single-sided, double-sided, multi-layer PCB production proofing, processing technology includes: gold plating, blind hole, gold deposition, silver plating, tin spraying, impedance and other processing methods.
Industrial Control Circuit Board
When the single-panel wiring can not meet the requirements of PCB electronic products, it is time to use PCB double-panel. So the double-panel is the spread of single-panel. Both sides of PCB double-panel have copper-clad wiring, and through holes can be used to conduct the circuit between the two layers, thus generating the required network connection.
Industrial control PCB board
PCB boards with more than three layers can be called multi-layer circuit boards. Conductive patterns above multi-layer boards and insulation materials between them are laminated separately. PCB boards with interconnected conductive patterns according to requirements have many functions, large capacity and high speed.
