PCB is the abbreviation of printed circuit board, and PCB proofing is to produce samples for testing before mass production, which also answers the market’s question about what is pcb proofing. Many electronics manufacturers will find some professional PCB proofing manufacturers to cooperate, so what problems should be paid attention to during the PCB proofing process?
PCB proofing needs to pay attention to what problems
First, pay attention to the number of proofs
Enterprises often need to make a batch of PCB prototypes for testing before mass production, and this part actually occupies a certain cost of the enterprise, especially when the enterprise has a large volume and produces more PCB types, then PCB proofing and testing The cost is also very impressive. From this point of view, companies should pay attention to the number of proofs in the PCB proofing process.
Second, to confirm the device package
Soldering a chip with a specific function on the board and packaging it with a shield is a process in the board fabrication process. In the process of PCB proofing, the commissioner should pay great attention to whether the internal chip and electronic components are soldered during the package to ensure the quality of the PCB prototype, and then the normal verification function and subsequent large-scale production.
Third, do a comprehensive electrical inspection
After the PCB proofing, the company 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 the PCB proofing. It is also whether the subsequent PCB board can be mass-produced and ensure extremely low defects. The guarantee of the rate. To conduct a comprehensive electrical inspection, it is recommended that the client and the proofing team cooperate to carry out the investigation to be a more rigorous test method.
Of course, there are some signal integrity layouts that require mutual attention and resolution, but in general, the issues that PCB proofing needs to pay attention to are roughly the above. Although there are many questions about the meaning of pcb proofing in the market, as a person in the industry, comprehensively checking and testing the above-mentioned problems is the basis for ensuring the quality of pcb samples and transforming them into subsequent large-scale production. Proofing must be taken seriously.
