3 Differences Between PCB Proofing and PCB Manufacturing
Proofing method Proofing, divided into regular manufacturers and only proofing manufacturers.
Regular manufacturers have more samples and more orders. Proofing manufacturers only make samples or small pieces, and generally cannot make large orders.
In terms of quality assurance, the factory is more professional than proofing. Proofing manufacturers charge factory fees when trading samples.
Proofing manufacturers generally do not perform flying probe testing. If the quality is not good, you have to pay again;
Those who do the needle test are all professional from the raw materials to the process, so the needle test is successful from the factory.
Problems that should be paid attention to in the process of PCB proofing
Pay attention to the sample size
In the past, what the company needed most was this, which actually took up a certain cost for the company, especially in the case of the large area and testing of the PCB production samples produced by the company, the cost of PCB proofing is also considerable. the process of. At this time, enterprises should pay attention to the number of proofing in PCB proofing.
Confirm device packaging
Soldering a specific chip on a circuit board and encapsulating it with its cover layer is an unusual feature in the circuit board manufacturing process. In the process of PCB proofing, the designated party should pay attention to whether the internal chips and electronics are soldered incorrectly in the process to ensure the quality of PCB proofing, verify normality, and further realize large-scale functional production.
Conduct a comprehensive electrical inspection
After the PCB prototype, the enterprise should conduct a comprehensive electrical inspection to ensure every function and every detail of the PCB. It is the meaning of the PCB sample, it can also be used to make a board, test the PCB board, and ensure the excellent quality of the product through mass production.
