The DIP plugin process is a part of the PCBA process after the SMT chip mounting process. DIP plugins refer to large-sized components that cannot be machine mounted, but require manual plugins, which are then welded through wave soldering to form the final product. The DIP plug-in process can be roughly divided into processes such as plug-in, wave soldering, foot cutting, inspection, testing, etc. The plug-in is the process of inserting the processed components into the corresponding positions of the PCB board to prepare for wave soldering; Wave soldering is the process of placing a plug-in PCB board into the conveyor belt of wave soldering, and completing the welding of the PCB board through various processes such as spraying flux, heating, wave repair welding, and cooling; Cutting the legs is the process of cutting the legs of the welded PCBA board to achieve the appropriate size; After the welding is completed, the PCBA finished board needs to be tested. If any functional defects are found, repair and retest should be carried out. If there are no problems during the testing, packaging and warehousing should be carried out.
As an important link in the PCBA process, the quality of DIP plugins determines the quality of PCBA processing. Therefore, when carrying out DIP plugins, we need to pay attention to the following matters.
1. Before inserting the plug-in, it is necessary to check the surface of electronic components for oil stains, paint, and other unclean objects.
2. During the plug-in process, it is necessary to ensure that the electronic components are flush with the PCB. After the plug-in is completed, it is necessary to ensure that the electronic components are flush and not uneven. At the same time, it is necessary to ensure that the soldering pins after the plug-in do not obstruct the soldering pad.
3. If there is a direction indicator on an electronic component, it is necessary to insert it in the correct direction and do not insert it randomly.
4. When inserting a plug-in, it is necessary to pay attention to the strength of the plug-in, and do not use excessive force during insertion, which may cause damage to the components or PCB board.
5. When inserting electronic components, do not push out the edges of the PCB board. Pay special attention to the height of electronic components and the spacing between them.
The DIP plugin process is complex, and there are many things to pay attention to during the plugin process. A malfunction in a certain link may lead to delayed delivery. Therefore, when choosing a PCBA processor, it is necessary to consider the strength, production capacity, quality control, and other aspects of the processing plant.
