PCB proofing refers to the production of a small amount of PCB prototypes for functional debugging before the circuit board starts mass production; after the functional debugging is completed, subsequent mass production can be carried out. This method can avoid production risks and reduce product errors. Loss.

PCB proofing is divided into two ways, namely, the formal pcb prototype manufacturer and the professional model company proofing. So, what are the differences between the two proofings?
1. The purpose of formal PCB factory proofing is to have bulk orders, and hope that customers can return orders; professional sample companies themselves only make prototypes or small batches, and generally can’t do it if there is a large order.

2. In terms of quality assurance, formal PCB factories are definitely better than professional model companies. Professional prototype companies usually charge money when the prototype is sent. They don’t even do basic flying probe testing, and they are not responsible for returning or replacing the product if there is a quality problem. Regular PCB factories generally do flying probe testing, which is meticulous and professional in materials and processes. PCB quality is guaranteed, and there is perfect after-sales service.

3. Generally, when doing a project, the designed PCB drawings will be sent to a professional prototype factory for proofing. First, a small amount of PCB boards will be tested. If the test passes, then we will find a formal PCB proofing factory for direct mass production. The price will be higher than that of the professional prototype factory. It is much lower; while the sample factory proofing is mainly fast.

POE focuses on PCB assembly manufacturing and proofing technology innovation and user experience, and has a team of product design engineers with rich experience. Various special processes that others do not want to do or rarely do can be made according to customer needs, such as Rogers, HDI blind buried vias, impedance control, single-sided aluminum substrate, single-sided copper substrate, FPC, rigid-flex, thick copper, Special-shaped holes, multi-layer special laminated structure, depth-controlled grooves, electroplated nickel gold/gold fingers, etc., solve the pain points of difficult boards, precision boards, and special boards in PCB proofing or assembly manufacturing for enterprises, and provide customers with high Quality and diversified PCB Assembly Manufacturing proofing services.
