PCB has many names, which can be called circuit board, circuit board, printed circuit board, etc. It is an important electronic component. As a bare board, PCB is used to mount electronic components, making electronic components and circuit boards. Connected to achieve a certain function.
PCB processing method:
Baking board (pre-expansion and shrinkage) - cutting - pre-treatment - dry film - exposure - development - etching - stripping - appearance inspection (AOI) - pre-treatment - solder mask printing ——Pre-baking——Exposure——Development——Post-baking——Character printing——Baking——Surface treatment (tin spraying, gold plating, gold plating, OSP, choose one according to customer needs)——Appearance inspection ——Shape cutting——Appearance inspection——Packing——Shipment
PCBA is the abbreviation of Printed Circuit Board Assembly. Generally, PCBA is translated as PCB Assembly. PCBA is a finished product formed by the bare PCB board after SMT patch, DIP plug-in and PCBA testing, quality inspection and assembly, etc., referred to as PCBA. It can realize the designer's design function, and almost all electronic products, such as smart home, AR, VR, medical equipment, etc., need to use PCBA board.
