PCBA Tech - SMT product design review and printed circuit board

SMT product design review and printed circuit board manufacturability design vehicle verification are important measures to improve SMT processing quality, increase production efficiency, improve reliability of electronic products, and reduce costs. This time mainly introduces the content, review and review procedures, and review methods of SMT product design review and printed circuit board manufacturability design review.

1. SMT product design review

SMT product design review should combine the characteristics of SMT process and equipment, and pay special attention to the review of manufacturability and manufacturability. Each stage should be summarized and regularly inspected and evaluated. The inspection and evaluation of each stage will not only improve the design, but also It can also play a role in supervision, inspection, implementation and assurance for the timely completion and realization of the expected functions, performance indicators, cost and other overall objectives of the product. The relationship between the three stages of design review, design verification, and design confirmation and the role of each stage.

Product design review should include designers, process personnel, complete machine manufacturing unit (production department), quality control department, planning and adjustment, outsourcing, business department, and if necessary, invite colleagues who are not the unit to participate. In the design confirmation stage. Some users should also be invited to participate.

The design review procedure is:

1. The design department puts forward a "design review report" to report the progress of the research and development work;

2. The process department puts forward a "product process summary report" to report on the implementation of the process;

3. The production department of the whole machine reports the problems in the design, technology, production management and other aspects of the product during the trial production process;

4. The outsourcing and quality control departments respectively report the conditions of trial production, technology and quality;

5. The management department reflects the maintenance and user feedback information;

6. The design department put forward rectification opinions;

7. Conduct detailed review and evaluation for problems in design, trial production and trial use, and put forward suggestions for improvement;

8. After listening to the opinions of all parties, the leader of the R&D department proposes solutions to the existing problems and draws conclusions;

9. PCB design and SMT process personnel will organize and summarize the content of the meeting, and compile the "review meeting minutes of the product trial production stage;

10. The leaders in charge sign their opinions on the "Meeting Minutes".

If after review and verification, the product design has met the expected functions, performance indicators, cost and other overall objectives, and has reasonableness, reliability, manufacturability and maintainability, then it can be decided to enter mass production.
