When doing PCB proofing, customers often put forward higher requirements on the delivery date of the manufacturer, the ability to handle complex samples, and product quality. What problems should be paid attention to in the PCB proofing process?
First, pay attention to the proofing quantity
Before mass production, enterprises often need to make a batch of PCB samples for testing, which actually accounts for a certain cost of the enterprise. Especially when the enterprise has a large volume and produces many types of PCBs, the cost of PCB proofing and testing is also very considerable. From this point of view, enterprises should pay attention to the number of proofs in the PCB proofing process.
Second, confirm the device packaging
It is a process in the circuit board manufacturing process to weld chips with specific functions on the circuit board and package them with a shielding cover. In the process of PCB proofing, the entrusting party should pay great attention to whether there is wrong soldering of internal chips and electronic components during packaging, so as to ensure the quality of PCB proofing, and then the normal verification function and subsequent large-scale production can be achieved.
Third, a comprehensive electrical inspection should be conducted
After PCB proofing, the enterprise should conduct a comprehensive electrical inspection to ensure that every function and every detail of the PCB are checked. This is the significance of PCB proofing, and also the guarantee of whether the subsequent PCB can be put into mass production and ensure a very low defect rate. To conduct a comprehensive electrical inspection, it is recommended that the client and the sampler cooperate to carry out troubleshooting, which is a more rigorous test method.
Of course, there are still some signal integrity layout issues 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 mainly the above items. Although there are many questions about the meaning of PCB proofing in the market, as insiders, a comprehensive investigation and testing of the above problems is the basis for ensuring the quality of PCB samples and transforming them into subsequent mass production. PCB proofing must be fully and seriously treated.
