First, pay attention to the number of samples
Enterprises often need to make a batch of PCB samples for testing before mass production, and this part actually occupies a certain cost of the enterprise, especially when the enterprise is large and produces many types of PCBs, then PCB proofing and testing The cost is also very considerable. From this point of view, enterprises should pay attention to the number of proofs in the process of PCB proofing.
Second, 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 PCB 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 PCB proofing, and then be able to verify the normal function and follow-up further large-scale production.
Third, do a comprehensive electrical inspection
After PCB proofing, the enterprise should conduct a comprehensive electrical inspection to ensure that every function and every detail of the PCB board is checked. This is the significance of PCB proofing, and it is also whether the subsequent PCB boards can be mass-produced on a large scale and ensure extremely low defects. rate of protection. To do a comprehensive electrical inspection, it is recommended that the entrusting party and the proofing party cooperate to carry out investigations, which is a more rigorous testing method.
Of course, there are still some signal integrity layouts that need to be paid attention to and solved by both parties, but generally speaking, the problems that need to be paid attention to in PCB proofing are roughly the above-mentioned items. Although there are many doubts about the meaning of PCB proofing in the market, as an industry insider, a comprehensive investigation and testing of the above-mentioned issues is the basis for ensuring the quality of PCB samples and converting them into subsequent mass production. For PCB Proofing must be taken fully and seriously.
