PCB has many kinds of name, can be called circuit boards, circuit boards, printed circuit boards and so on, is an important electronic components, PCB as a bare board, was used to mount electronic components, so that electronic components and circuit boards connected to achieve certain functions.
PCB processing methods:
Baking board (pre-shrinkage) - opening - pre-treatment - paste dry film- -exposure - development - etching - stripping - appearance check ( AOI) - Pre-treatment - Soldermask printing - Pre-baking - Exposure --Developing - Post-baking - Character printing - Baking - Surface treatment (tin spraying, chemicalization, etc.) -Surface treatment (tin spraying, gold plating, gold plating, OSP, according to the customer's needs to choose one) - Appearance inspection - shape cutting - Appearance inspection - Packaging - Shipping Inspection - Packaging - Shipping
PCBA is the abbreviation of Printed Circuit Board Assembly, but in foreign countries, generally translated PCBA PCB assembly (PCB). PCBA is a PCB bare board after SMT chip, DIP plug-in and PCBA test, quality inspection assembly process, the formation of a finished product, referred to as PCBA. can realize the designer's design function, almost all electronic products, such as smart home, AR, VR, medical equipment, etc., all need to use PCBA board.
