PCB proofing refers to making a small amount of PCB samples for functional debugging before the mass production of the circuit board; after the functional debugging is completed, follow-up mass production is carried out. This approach avoids production risks and reduces product errors. lose.

There are two ways for PCB proofing, namely conventional PCB factory proofing and professional sample company proofing. So, what is the difference between these two proofs? Now, let me tell you.

1. The purpose of regular PCB factory proofing is to have bulk orders and hope that customers can return them; professional sample companies only make samples or small batches themselves. If there are large orders, they generally cannot do it.

2. In terms of quality assurance, regular PCB factories must do better than professional model companies. Professional sample companies usually collect money when the samples are shipped. We don't even do basic flying probe tests, and we are not responsible for returning or replacing goods if there are quality problems; regular PCB factories usually do flying probe tests, which are meticulous and professional from materials to craftsmanship, so the quality of PCBs is guaranteed and there is perfect after-sale service. Serve.

3. Generally, for a project, the designed PCB drawings will be proofed by a professional sample factory, and a small number of PCB boards will be tested first. If the test is passed, then the formal PCB proofing factory will directly produce in large quantities, and the price is higher than that of the professional sample factory. Much lower; while the prototype factory proofing mainly highlights fast.
