What are the precautions for SMT chip processing factory?
Time:2023-06-21 Read: 2395

With the development of science and technology, many electronic products are developing in a small and refined direction, which makes the size of many SMD components smaller and smaller. Not only the requirements for the processing environment continue to increase, but also the higher requirements for the chip processing technology. In order to do a good job in PCBA processing, SMT chip processing plants need to do at least the following three things.


First of all, when doing SMT processing, we all know that solder paste is required. For newly purchased solder paste, if not used immediately, it must be stored in an environment of 5-10 degrees. In order not to affect the use of solder paste, it must not be stored in a sub-zero environment.


Secondly, during the placement process of the SMT process, the placement machine equipment must be checked frequently. If the equipment is old or some parts are damaged, in order to ensure that the placement machine does not tilt, the material will be thrown out, and the equipment must be repaired or replaced with a new one. Only in this way can production costs be reduced and production efficiency be improved.


Finally, in the SMT chip processing process, in order to ensure the soldering quality of the PCB, we must always pay attention to whether the setting of the reflow soldering process parameters is reasonable. If there is a problem with the parameter settings, the quality of the PCB board soldering cannot be guaranteed. Therefore, under normal circumstances, the furnace temperature must be tested twice a day, at least once. Only by constantly improving the temperature curve of welding products and setting the temperature curve of welding products can the quality of processed products be guaranteed.
