I. Preliminary preparation stage
1. PCBA project specification, technical parameters and requirements;
2. Preparing the project lead group, responsible for process design, process implementation, project reporting, etc.;
II. Design and development
The standard of this link is the circuit design ability that can meet the SMT production process.
III. Design and editing of SMT production process operation instructions
1. The format of the work instruction book is clear, which is consistent with the pcba processing plant;
2. The content of the operation instructions is clear (the operation instructions for the selection of solder paste, the operation instructions for the use of stencils, the patch processing operation instructions, the reflow welding process control instructions, etc.);
IV. Confirmation of steel mesh production capacity
1. The manufacturing process of steel mesh;
2. The patch processing factory exports the Gerber file suitable for stencil production from the PCB file to guide the stencil production process;
V. Confirmation of the programming and operation ability of the placement machine
1. Evaluation of BOM list and Gerber files;
2. SMT programming, PCB size measurement and panel processing;
VI. PCBA assembly test
1. Test after SMT chip processing and production (aging, programming, signal, high and low temperature, ICT test, etc.);
2. Three-proof paint coating, etc. (which three-proof refers to, please refer to our previous analysis of this problem);
VII. PCBA patch project improvement and evaluation
1. PCBA design mutual inspection;
2. Reporting;
3. Improvement suggestions.
The above is what are the steps to do PCBA? The introduction of the seven major steps of the PCBA project, I hope it can help you, and if you want to know more about PCBA processing information, you can pay attention to the update of ZENS proofing.
