1. Refrigerate solder paste

The solder paste has just been bought back, if it is not used immediately, it should be refrigerated in the refrigerator, and the temperature should be kept at 5℃-0℃, not lower than 0℃.

2, timely replacement of the chip machine easy to wear

In the mounting process, due to the aging of the mounter equipment and the damage of the suction nozzle and the feeder, it is easy to lead to the skew of the mounter and the occurrence of high throwing material, which reduces the production efficiency and increases the production cost. In the case that the placement machine equipment cannot be replaced, it is necessary to carefully check whether the nozzle is blocked, damaged, and whether the feeder is in good condition.

3. Measure the furnace temperature

The welding quality of PCB board has a great relationship with whether the process parameters of reflow welding are reasonable. In general, it is necessary to conduct two furnace temperature tests, at least once, to continuously improve the temperature curve to achieve the temperature curve of the welded product. Do not omit this link for the sake of productivity and cost savings.

4, control the workshop environment

SMT chip processing has certain requirements for environment, humidity and temperature; In order to ensure the quality of mounting, it is necessary to ensure that the machining shop meets the requirements of the working environment.
