Why is it necessary to produce PCBA samples before mass production?
PCBA sampling is a small-batch PCB SMT patch processing trial production and verification test conducted by customers due to the design requirements of new products, to ensure that the product design meets the expected design requirements. Generally speaking,
What is a PCBA sample?
PCBA sampling is a small-batch PCB SMT surface mount processing trial production and verification test conducted by customers due to the design requirements of new products, to ensure that the product design meets the expected design requirements. Generally,
the quantity of PCBA samples is less than 30 pieces.
Reasons for making PCBA samples.
Usually, before mass production, customers will choose one or more suppliers to produce test samples. What is the purpose?
1. Check if there are any problems with the PCB design, and whether any modifications are needed.
2. Whether the produced PCBA board meets the expected functions, and what needs to be improved.
3. Screen out capable factories to ensure the yield and test pass rate of PCBA production, evaluate the approximate delivery time and quality, and accurately estimate various aspects of future large-scale orders.
What documents are needed to make PCBA test samples?
1. BOM list
2. Stencil Gerber files for the panel
3. Screen printing
4. Pick and place file
5. PCB file (To protect customer files, we often suggest that customers delete the inner layers when sending files to us, keeping only the top and bottom layers)
Able to judge the strength level of the circuit board manufacturer
Effective pre-production PCB sampling can also clearly understand the strength of the circuit board manufacturer, especially for manufacturers who have not cooperated before. Through sampling, the strength and capabilities of the circuit board manufacturer can be judged. Only manufacturers with comparable strength and processing technology that meet the standard requirements can meet the requirements and better meet the requirements of long-term cooperation and high-quality processing and production of PCB boards by enterprises.
Can reduce the defect rate of PCB mass production
Usually, the production volume of PCB boards is relatively large. In order to ensure smooth mass production and avoid quality problems and reduce the defect rate, it is very necessary to sample the circuit board before production. After all, the processing of PCB boards requires complex processing procedures, and every procedure or processing link cannot go wrong. After successful sampling, professional technicians will conduct effective tests on the samples, and mass production can only be carried out after confirming that there are no problems through various professional tests.
PCB sampling is also to understand the performance and functional response of new products in advance. Through sampling, a good foundation can be effectively laid for future mass production. Appropriate material cost accounting can also optimize shortcomings, and effectively handle the needs during the sampling process in advance, which can reduce various unexpected problems during mass production.
It can be seen that sampling is very necessary before the official launch of the PCB, and it is also a step towards successful cooperation with processing enterprises. Therefore, it is necessary to choose a reasonably priced PCB manufacturer for sampling, and before formally conducting PCB sampling, good communication and negotiation should be conducted with the material processing size requirements or the size of the required materials provided by the manufacturer. This also lays a good foundation for better cooperation between the two parties in the future.
