Quality control is very important for patch plug-in processing. Only through effective quality control can we ensure the processing quality of patch plug-in, so as to obtain the best processing effect
SMT processing materials on the PCBA welding quality of the impact of the following: 1, the impact of components, 2, PCB, 3, the impact of solder paste
PCBA processing and SMT processing differenceThe whole process of PCBA processing actually includes SMT patch processing. SMT patch processing is only part of the PCBA process, which literally means a wider range of processes
The following are four ways to ensure the quality of PCBA processing: 1. Quality control, 2. Inspection and testing, 3. Use high quality raw materials: 4. Professional technical team
Ways to improve SMT machining efficiency: (1) Aim for fewer component changes, (2) Focus more on PCBA assembly, (3) You should know every step of the SMT process
Core and key points of SMT process: The goal of SMT process is to produce qualified solder joints. A good solder joint depends on the right pad design, the right amount of solder paste and the right reflow temperature curve
Here are some possible reasons for potential growth: 1. PCB solder resistance details; 2. Surface treatment; 3. Screen printing; 4. Impedance details: 5
Classification of PCBA inspection items: inspection items are divided into four categories: material inspection, process inspection, identification inspection and quality consistency inspection
PCBA proofing processing common production procedures :1. Repair: 2. Mounting: 3. Testing: 4. Curing: 5. Cleaning: 6. Solder paste printing: 7. Reflow welding: 8. dispensing
The main reasons for poor wetting are: 1, the surface of the welding area is polluted, 2, when the residual metal in the solder exceeds 0.005%, the activity of the flux is reduced, 3, wave soldering, there is gas on the surface of the substrate,
SMT machining components are repaired: 1. Chip components welding disassembly, 2. Pad cleaning, 3. Assembly and welding of chip components
Kingford is a PCB company engaged in the production and assembly of circuit boards. We not only sell PCBA, but also have many strategies related to PCB design and PCB proofing. Next, let me introduce you to some matters related to PCB.
