1. Management of solder paste printing process
The first is the management of preparation before Smt Smt printing:The first point requires the related personnel to be familiar with the process requirements of the product;The standards for selection, collection and inspection of PCB, template and solder paste should be established, such as Sn43/Pb43/Bi14, Sn42/Bi58 at low temperature, Sn96/Ag4 at high temperature, lead free and high tension,Sn96/Ag4,Sn95/Sb5,Sn96.5/Ag3.0/Cu0.5, Sn95.5/Ag3.8/Cu0.7 at high temperature.High temperature, high tension and low value application Snl0/Pb90, Sn10/Pb88/Ag2, Sn5/ pb93.5/ag1.5. If the PCB is found to be damp or contaminated, cleaning and baking shall be conducted according to the cleaning standard and baking standard respectively.
Firstly, make PCB positioning and template installation standards;
The position responsibility and requirements of printer equipment engineer are formulated.Establish the position responsibility and requirements of solder paste adding operators;The first point is to develop the process file of Smt Smt printing parameter setting.The control point is to establish the technical standard for adding solder paste.The first point is to establish the inspection standard.
The operation of the printing press and the setting of printing parameters shall be implemented according to the process documents.Above point, the addition of solder paste by the special person responsible for the operator to carry out training.The first screen point, implement the first test printing and first test system
The first step is to establish a process inspection system to examine each PCB after printing.The inspection methods and standards are guided by the corresponding process documentsDaily maintenance and record of the printing press.The second point is that all actions should be recorded accordingly
3. Management after printing
When the production of a product or one day of work is completed, the printing parameters are set to zero, the template, scraper and other equipment are cleaned and placed as required.The above is the Smt patch manufacturing process management provided by jingbang for you, I hope it is helpful to you.
