PCB multi-layer board outsourcing processing requirements

The processing of printed boards 7 is generally external processing, so when providing drawings for external processing, it must be accurate and explain as clearly as possible. Attention should be paid to materials such as material selection, lamination sequence, plate thickness, and tolerances. Requirements, processing technology, etc., must be clearly explained. When exporting GERBER from PCB, it is recommended to use RS274X format for export data, because it has the following advantages: CAM system can automatically input data, the whole process does not require manual participation, which can avoid a lot of trouble, while maintaining good consistency and reducing travel rate .
