What should be paid attention to in post welding of dip plug-ins?
As we all know, post welding of dip plug-in is a particularly important process in PCBA patch processing. Its processing quality directly affects the functional performance of PCBA board, so it is necessary to pay more attention to the post welding process of dip plug-in. There are many preparations for post welding of dip plug-ins. The basic process is to deal with electronic components first. The staff collects materials according to the bill of materials, checks whether the material model and specification are correct, and carries out pretreatment before production according to PCBA template.
Which is good for post welding of dip plug-ins
Precautions for post welding processing of dip plug-ins:
1. The horizontal width of the sorted component pins shall be the same as the width of the positioning hole, with small tolerance.
2. After the dip plug-in is soldered, the distance between the component pin and the PCB pad should not be too large.
3. The post welding parts of dip plug-ins need to be molded with fixtures to provide mechanical support and prevent pad warping.
4. Paste high-temperature adhesive tape, paste high-temperature adhesive tape where protection is needed, and block tinned through holes and electronic components that must be welded.
5. When performing post welding processing of dip plug-ins, the staff must wear anti-static bracelets, anti-static gloves, anti-static shoes and anti-static caps to prevent static electricity. The post welding processing of dip plug-in shall be carried out according to the part list and part number drawing. The post welding processing of dip plug-ins shall be carried out in an orderly manner, and care shall be taken not to make mistakes.
6. For components inserted after dip plug-in post welding, please carefully check whether they are inserted incorrectly.
7. For the printed circuit board with no problem in post welding the dip plug-in, the next step is wave soldering. Wave soldering machine is used to weld printed circuit boards to fix components.
8. Take out the high-temperature adhesive tape, and then check whether the welded printed circuit board is well welded.
9. Printed circuit boards that are not fully welded shall be repaired and maintained.
10. Then there is the post welding process of dip plug-in. Due to the limitations of process and materials, some parts cannot be welded by wave soldering machine and can only be completed manually.
After dip plug-in post welding processing, the printed circuit board after welding shall be subject to function test. Before the test, confirm whether the equipment is normal, whether the working air pressure and program settings comply with the operating procedures, and whether the test tools comply with the model and specification. If there is any abnormality, contact relevant personnel in time. Test whether all functions of PCBA board are normal. In case of any abnormality, repair and retest shall be carried out.
SMT贴片加工质量的管控
建立SMT贴片加工装配设备维护规章制度是非常必要的。确保设备始终处于正常运行的良好状态是保证电路板产品质量和生产效率的重要手段。SMT贴片加工质量的管控如下：
SMT贴片加工哪家好
加强对机器的日常维护：
SMT贴片加工设备是一种非常复杂的高科技高精度机器，需要恒温、恒湿和清洁的环境。必须严格按照设备规程的要求，坚持每日、每周、每月、每半年和每年的维护措施，做好日常维护工作。
对设备SMT贴片加工操作员的要求：
SMT贴片加工操作人员应接受一定的工管专业知识和技术培训。严格按照机器的操作程序操作。不允许操作有故障的设备。如发现故障，应及时停机并报告给技术负责人员或设备维护人员，使用前应将其清除。
要求SMT贴片加工操作人员在操作过程中集中精力，眼睛、耳朵和手要勤奋。目视-观察机器运行过程中是否有异常现象，如卷带器无动作、塑料胶带断裂、安装不当等。
制定减少或避免错误的措施：
SMT贴片加工粘贴时，最常见和最频繁的错误是元件错误和安装位置不当。因此，制定了以下预防措施。
给料器编程后，必须指定专人检查给料站每个编号位置的元件值是否与编程表中相应给料器编号的元件值一致。如果有任何不一致之处，必须予以纠正。
对于SMT贴片加工色带进给器，当每个托盘被安装和重新填充时，必须由专人检查新托盘值是否正确。
补丁编程后，必须编辑一次，以检查每个安装步骤的部件号、旋转角度和安装位置是否正确。
每批安装第一件SMT贴片加工产品后，必须有专人检查。发现的问题应通过修改程序和其他方法及时纠正。
在SMT贴片加工安装过程中，经常检查安装位置是否正确，材料是否被抛出。及时检查发现的问题并消除它们。
总之，SMT贴片加工的安装速度和安装精度是确定的。如何发挥机器的应有作用，人为因素对于制定有效的规章制度和管理措施，保证机器的正常运行，确保安装质量和效率非常重要。
