PCB (Printed Circuit Board) is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. Because it is made by electronic printing, it is called a "printing" circuit board.

PCB copy board, that is, under the premise that there are electronic products and circuit boards, the reverse analysis technology is used to reversely analyze the circuit board, and the original product PCB file, bill of materials (BOM) file, schematic file And other technical documents and PCB silk screen production files for 1:1 reduction, and then use these technical documents and production documents for PCB board, component soldering, flying probe test, circuit board debugging, complete the complete copy of the original circuit board template.
