What does PCB proofing mean? Why PCB proofing? What is the function of PCB proofing? PCB proofing refers to that the designer has designed the drawings, but in order to ensure no mistakes and ensure the perfect performance of PCB, the test products, i.e. samples, will be made before mass production.

At present, the typical process of printed circuit board (PCB) processing adopts "graphic electroplating method". That is, a layer of lead tin corrosion resistant layer is pre plated on the copper foil to be retained on the outer layer of the board, that is, the graphic part of the circuit, and then the rest of the copper foil is chemically corroded, which is called etching.
