What should I pay attention to when doing PCBA testing?
After the PCBA test fixture is formed, simply swing the PCBA board into the test fixture to complete the positioning of the PCBA board and the test fixture. The accuracy of positioning is closely related to the manufacturing process of the test fixture.
To confirm the integrity and accuracy of the product and avoid excessive rework caused by assembly processes and operating methods, PCBA manufacturers can use PCBA testing to solve problems. However, the industry also emphasizes that PCBA testing is not omnipotent, and there are still several areas that need to be noted in the actual operation process.
In PCBA testing, the following aspects should be noted:
When PCBA needs to be upgraded, most motherboards will undergo significant changes. Industry insiders emphasize that traditional batch production of PCBA motherboards from different periods cannot be mixed with after-sales motherboards, because once mixed batch production occurs, it is easy to run into mixed batch boards, which is detrimental to the later use of electronic products. Therefore, when testing and assembling PCBA, it is important to determine whether the final usage code meets the customer's requirements.
●Before PCBA testing and assembly, the dirt on the fingers should be removed first. It is best to wipe them with dust-free material and alcohol, and then do so again to avoid the user's hands being unable to perform certain key operations on the circuit card due to these dirt.
●Anti static measures must be taken, whether it is PCBA testing and assembly or other processes. The purpose of this step is to avoid poor contact or power on of electronic products during use, thereby improving product quality and user experience.
