With the rapid development of industry, various electronic components tend to be smaller and more precise. SMT nozzle is also the same. We all know that the nozzle has a relatively large impact on the placement quality. Throughout the placement application, the nozzle will work for a long time to cause clogging, such as some flux and residual tin and other dirt. Here are 3 common ways to clean the placement nozzle
Manual manual cleaning.
Alcohol + air gun + washing water. This cleaning method is completely obsolete. This method requires a lot of human labor, time-consuming and labor-intensive. The point is that it can not clean the nozzle cavity, and if the alcohol seeps into the reflector glue, it will cause the reflector to fall off and fade.
Ultrasonic cleaning machine cleaning.
The advantage of ultrasonic cleaning is that the cost is lower, but also can clean some larger nozzles. The advantage of ultrasonic cleaning lies in the fact that it can clean the dirt off the surface of the object without damaging it, whether it is a crevice nook or a through hole blind hole, as long as the water can reach it, it can be cleaned. So it is very suitable for SMT suction nozzle cleaning work.
High-pressure water mist cleaning.
High-pressure water mist cleaning machine, also known as automatic nozzle cleaning machine, adopts unique mechanical design, using fluid mechanics to break up the water and produce a very fine high-pressure water mist, forming a powerful kinetic energy spray on the nozzle, forming a continuous energy field above the nozzle to be cleaned, thoroughly crushing the surface and internal dirt (because the nozzle is placed independently, the nozzle will not be damaged during the cleaning process), and automatically discharging directly during the cleaning process Cleaning solution (deionized water or distilled water) Can clean impurities and dirt that are difficult to clean by ultrasonic; does not damage the surface coating and reflector, and extends the life of the nozzle.
