1. Selection of proofing methods

PCB proofing can be divided into three ways, namely regular PCB factories, professional sample companies and a few board copying companies. Users should choose according to their actual needs. Generally speaking, in terms of quality assurance, the regular PCB factory must do a little better than the sample company. For example, Shun Yi Jie usually does flying needle test. They are careful and professional from material to process, and the quality is guaranteed.

2. Confirmation of proofing information

Users should have a clear understanding and regulation of PCB proofing process requirements, so as to correctly communicate to the service provider. Include the size of the plate that needs what type, board child, layer number, quantity and thickness to wait a moment these factors should have decided first.

3. Comparison of sample price

At present, many PCB proofing manufacturers have access to the ERP system to support the online pricing function, which makes the proofing price transparent. Therefore, users in the preliminary selection of proofing manufacturers can be compared with the price advantage to see which service providers can create more cost-effective space for themselves, so as to make a choice again.
