1. Judging the strength level of circuit board manufacturers: Effective PCB sampling before production can also provide a clear understanding of the strength of circuit board manufacturers, especially those who have not cooperated with them before. By sampling, the strength level of circuit board manufacturers in production can be determined. Only circuit board manufacturers with comparable capabilities and the ability to process circuit boards that meet standard technical requirements can be determined, To better meet the requirements of long-term cooperation and high-quality processing and production of PCB boards.

　　2. Reduce the defect rate in batch production of PCB circuit boards: The processing and production volume of PCB boards are relatively large. In order to ensure smooth mass production without quality problems and reduce defect rates, it is very necessary to conduct circuit board sampling processing before production. The processing of PCB boards requires complex processing procedures, and each process or processing link will not have errors. After successful sampling, Professional technicians will effectively test the samples, and after various professional tests, it will be confirmed that there are no problems and can be mass-produced.

　　3. Lay the foundation for future batch processing: PCB sampling should also have prior understanding of the performance and functional response of the new product. Through sampling, it can effectively lay a good foundation for future batch production. The calculation of corresponding material costs can also optimize shortcomings in advance. Effective link processing can reduce the occurrence of various unprepared problems during batch production.
