PCB is the abbreviation of printed circuit board, and circuit board proofing is to produce a small number of samples for testing before PCB mass production, which also answers the market's question about what is a circuit board.
Proofing questions. Many electronics manufacturing companies will find some professional circuit board proofing manufacturers to cooperate, so what should be paid attention to in the process of circuit board proofing?
1. Pay attention to the number of circuit board proofingGeneral enterprises often need to make a batch of circuit board proofing for testing before mass production, and this part actually occupies a certain cost of the enterprise, especially when the enterprise uses a large amount and produces many types of PCB circuit boards, then circuit board proofing And the cost of testing is also extremely considerable. From this point of view, enterprises should pay attention to the number of proofs in the process of proofing circuit boards. Generally, the number of proofs is about 5-10pcs. Some customers require 20pcs, and the specific sample quantity is still subject to customer requirements.
2. Do a comprehensive electrical inspection
After the circuit board proofing, the enterprise should conduct a comprehensive electrical inspection to ensure that every function and every detail of the circuit board is checked. The guarantee of low non-performing rate. To do a comprehensive electrical inspection, it is recommended that the entrusting party and the proofing factory cooperate to carry out investigations, which is a more rigorous testing method.
3. To confirm the device package
Soldering chips with specific functions on the circuit board and encapsulating them with a shield is a process in the circuit board manufacturing process. In the process of circuit board proofing, the entrusting party should pay great attention to whether the internal chips and electronic components are wrongly soldered during packaging, so as to ensure the quality of circuit board proofing, and then be able to verify the normal function and follow-up further large-scale production .
