  • Why is it difficult to tin in PCB pads?

    Why is it difficult to tin in PCB pads?

    The first reason:We should think about whether it is a customer design problem. It is necessary to check whether there is a connection mode between the pad and the copper sheet, which will lead to insufficient heating of the pad. The second reason : Whether it is a customer operation problem. If...

  • What problems should be paid attention to in the etching in PCB proofing?

    What problems should be paid attention to in the etching in PCB proofing?

    In PCB proofing, a layer of lead-tin resist is pre-plated on the copper foil part to be retained on the outer layer of the board, that is, the graphic part of the circuit, and then the remaining copper foil is chemically etched away, which is called etching. So, in PCB proofing, what problems sho...
