SMT SMD processing purchaser needs suppliers to provide one-stop processing services, in the supplier quotation before the purchaser needs to provide some information to the supplier, to facilitate engineers and procurement for process, quotation evaluation. Adequate communication and cooperation on the basis of the previous period can speed up the generation of quotes, reduce product delivery delays, the product on line in a timely manner is of great help.
Today on the patch processing purchaser needs to provide the supplier what information
1) BOM list
BOM refers to the electronic bill of materials, simply put, the supplier to patch the PCBA board contains which materials, materials corresponding to the brand, model, specification, quantity, detailed BOM form can be more accurate quotation, conducive to the supplier according to the number of components for the correct, timely and rapid quotation
2) Gerber file
Gerber means the relevant information of the PCB board, including Pad layer, solder resist layer, screen printing layer, stencil layer, the supplier has Gerber file, can provide better assistance to the quotation.
3) Coordinate file
Coordinate file refers to the coordinate positioning of the components on the PCB (indicating the position of different electronic components on the PCB board), the engineer needs to use this file when adjusting the machine to do the SMD procedure.
4) Process reference file
Process is mainly to the processing process notes control, that is, the production processing guiding documents, including special requirements and test requirements
5) test instructions
Contains the test categories and projects, including the technical indicators of the test, the test belongs to the process category, the more test requirements, the higher the process charges.
The above five points are the chip processing manufacturers need to request the relevant information to the purchaser, the supplier according to these document requirements, to be able to quickly and accurately quote.
