What Should be Paid Attention to in PCBA Repair
When doing PCBA processing, we occasionally encounter some boards that need to be repaired. Repair is also a very important link. Once errors occur, it may directly lead to the scrapping of the circuit board. So what should we pay attention to when repairing? 1. If there are solder joint defects such as open circuit, bridge, and virtual soldering generated in the reflow or wave soldering process, it is necessary to use tools, such as BGA rework station, X-Ray, high-power microscope, etc., to remove various solder joint defects after trimming. So as to obtain qualified PCBA solder joints. 2. If the repair process needs to be heated above 110 ° C, or there are other moisture-sensitive components within 5mm of the repair area. 3. For moisture-sensitive components that need to be reused, if hot air reflow, infrared and other repair processes are adopted through the heating solder joint of...
