What Should Professional SMT Factories Pay Attention to When PCBA Processing

With the development of electronic products in a small and precise direction, the size of many SMD components is getting smaller and smaller, not only the requirements of the processing environment are constantly improving, but also higher requirements for the SMT processing technology. To do a good job in PCBA processing, a professional SMT factory must do at least the following 3 points.

 

1. Solder paste needs to be used during SMT processing. After the SMT factory purchases the solder paste, if they don't use it immediately, they must put it in an environment of 1-10°C, instead of placing it in a light-irradiated place or storing it in an environment below 0°C! This is to ensure that the quality of the solder paste does not affect subsequent use.

 

 

2. The SMT factory must check the placement machine equipment frequently. If the equipment is aging, or some parts are damaged, the equipment must be repaired or replaced with new equipment in time. This is not only to ensure that the patch will not be pasted crooked or high-throwing materials occur, but also to improve production efficiency.

 

 

3. In order to ensure the quality of PCB soldering, when performing SMT processing, the SMT factory needs to always pay attention to whether the setting of reflow soldering process parameters is reasonable. If there is a problem with the parameter setting, the quality of PCB soldering cannot be guaranteed. In general, the furnace temperature needs to be tested twice a day, at least once. Only by continuously improving the temperature curve and setting the temperature curve of welding products can the processed products be guaranteed to be of high quality.
