1. It is better for the material to be formed at the supplier, instead of being processed after entering the factory 2. Some components should be considered as far as possible using the method of mac……
5G circuit boards not only provide electrical connections for electronic components, but also carry complex functions such as digital and analog signal transmission, power supply, RF and microwave sig……
1. Prepare SMT chip processing materials in advance (SMD BOM, SMD position coordinates, SMD pictures, templates, etc.) and send them to the processing plant. It is required to prepare the SMT offline ……
1. Aging test Put the PCBA board with the test function OK under specific temperature and humidity conditions, and perform repeated opening and closing, simulation function operation, load operatio……
Advantages of Even Layer PCBs 1. Low cost Due to the lack of a layer of dielectric and foil, the raw material cost of odd-numbered PCBs is slightly lower than that of even-numbered PCBs. However……
1. The components are not placed correctly Some high-power equipment needs to reserve natural ventilation or forced ventilation to dissipate heat. Without proper airflow to dissipate heat, the PCB ……
BOM is a very important information in SMT processing, it is the abbreviation of Bill of Components. It lists all the components required on the circuit board and the specification parameter informati……
11. Test optimization 11.1 Make use of customer specifications and electrical characteristics of products to synthesize the most effective test items that can detect product problems, so as to avoid ……
PCB = printed circuit board, PCBA = printed circuit board + components When it comes to PCB and PCBA, we have to mention SMT. SMT is a surface assembly technology. It is a popular process technolog……
