PCBA welding processing usually has many requirements for PCB board, which must meet the welding requirements. So why does the welding process require so many requirements for circuit boards? Facts have proved that there will be many special processes in the process of PCBA welding, and the application of special processes will bring requirements to PCB.
QA activities run through the whole process of project operation; QC activities are generally set at a specific stage of project operation, and may be completed by different roles at different control points. For competent QA, tracking and reporting findings during project operation is only the basic part of their job responsibilities. More valuable work includes providing process support to the project team, such as providing cases and reference data of previous similar projects for the project manager, introducing and explaining applicable process definition documents for project team members, etc. QC's activities are mainly to find and report product defects.

CBA test is the most critical quality control link in the whole PCBA processing process. It is necessary to strictly follow the PCBA test standard and test the test points of the circuit board according to the customer's test plan. PCBA test also includes five main forms: ICT test, FCT test, aging test, fatigue test and test in harsh environment.
PCBA processing and production quality and efficiency are closely related to the design method of PCB circuit board itself. Good design can solve the problems of processing and production quality, efficiency and even cost. If the PCB design is not standardized or the problems are not considered comprehensively, it will seriously affect the production quality and efficiency, and directly or indirectly lead to the improvement of production cost.
Solar street lamp is a comprehensive system. All components should be reasonably configured according to parameters to achieve the best use of solar street lamp. In addition, we should not only pay attention to the solar street lamp controller, solar battery and LED light source, but also pay attention to the selection of solar street lamp panel, because solar panel is a component that directly affects the power generation efficiency of solar road, and the power generation efficiency affects the amount of electricity stored in the battery, thus affecting the overall lighting effect of solar street lamp.
