Method for eliminating circuit board welding defects

Method for eliminating circuit board welding defects

Usually, we refer to the poor welding of electronic products in the factory as a defect.SMT products performance anomalies that occur outside the plant are called failures.

In the circuit board manufacturing factory, for the specific welding defects found in the visual inspection and the defects affecting the performance found in the electrical performance test, the defect can be handled by the inspection department in the factory, leaving the defect record, and then mark defect position in the physical object. Making appropriate repairs and then sent for inspection. Before you setting measures to eliminate defects, you must fully understand what is the problem with existing defects. After fully understanding the problem, you can use statistical methods to find the root cause of the problem. If it is found that there are many specific welding defects in the visual inspection, the quality report collected by the inspection department can be fed back to the processing workshop and the technical department. These departments can analyze the investigation reasons and formulate practical measures according to the quality report. If it is found in the electrical performance test that the defects affecting the electrical performance and the defects caused by the operator failing to weld properly, the quality management department of the factory shall personally check the welding defects and find out the reasons and make related measures.

 

 

For the various defects caused by the manual welding of the operator, it is necessary to pay attention to various related matters during the operation of the plug-in to achieve good welding.
