Nc 120 Automatic Nozzle Cleaner (NC120)

The demand of cleaning the nozzle 1. The pitch becomes more smaller: Nowadays the electronic facility becomes smaller while the function becomes stronger. In the past the discrepance would not too harmful, by contrast, the disqualification rate would increase now. 2. The affection of lead-free: Due to the good function of the lead in the soldering tin, the discrepance would be corrected automaticly while the PCB though the reflow soldering. But if the pull force of the tin paste with lead-free is weak, the chance of the emendation though reflow soldering would be small. What is worse, if there is a discrepance, there will be no chance to rework. 3. The miniaturization of the components: With the development of the electronic industry, the encapsulation of the chip and the components become miniaturization. With the wide use of components 0402/0201/10005, the nozzle becomes more smaller. We use alcohol and thin acicula to clean the big nozzle, but there is no way to clean the small one in the same way. It will be discarded as useless if build up. The elements of the traditional cleaning method 1. Alcohol&wind gun: Use cloth to soak alcohol to clean, then blow it with wind gun. Disadvantage: Employ more manpower, could not clean the tube cavity of the nozzle and would lead to the depigment of the baffle-board if the alcohol infiltrate into the gluewater. 2. Ultrasonic cleaning machine: This is a widely used method because of low cost and satisfactory efficiency, however, many manufacturers forbid it. Disadvantage: Different nozzle would barge against each other and result in a damage of the vital black paint-coat. The infiltration of the lotion would also lead to the baffle-board fall off. And there is no way to clean the cube cavity of the nozzle. 3. The lotion is harmfull to the environment commonly.
