FAQ
Which is better for cleaning: dry ice or plasma?
Dry ice cleaning is mainly a physical method to clean stubborn stains, burrs, rosin, furnace surfaces, etc.
Plasma is mainly a chemical method, and physics plays an auxiliary role, activating the surface of the object, increasing the surface energy, and enhancing the surface adhesion.
What is the probability of electronic components on the PCBA board being broken down?
Factors that affect static electricity: height, speed; our static electricity can be as low as 3V, or even lower. We need to confirm whether there are components that are sensitive to static electricity and the requirements for the water drop angle. The requirements for each board are different, and we can support test proofing;
When do I need to change parts and spray guns? How much is maintenance?
What may need to be replaced are the nozzle and electrode on the spray gun. If the power is set below 600W, it can be used for 1 year. The lower the power, the longer it can be used. In extreme cases (800-1000W), it can be used for 6 months.
清洗是否有残留，能被抽风机抽走吗，残留物是否会造成二次污染？被冲刷掉的颗粒灰尘会留在底部吗？多久需要清洁一次？
化学反应的部分是没有残留的。等离子与污渍反应主要就是生成气体，二氧化碳、一氧化碳、臭氧、一氧化氮等，直接就被强抽抽走了。如果客户的产品表面确实粉尘大污渍比较多，最好先把表面残留物擦掉、或者水洗后再使用等离子清洗。
在非无尘环境下，清洗完到下一步工序，能保持多久？
水滴角保持多久，与环境中的湿度、氧气含量有关，氧气会和产品表面形成薄膜，被氧化。不同物质被氧化的速度也不一样，所以保持效果都是因材质不同而定的。建议清洗完就直接进行下一步工序，实在需要放置，可以放在氮气柜。
