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.
Residue? Exhaust remove? Contamination? Bottom particles? Clean how often?
There is no residue in the chemical reaction part. The main reaction between plasma and stains is to generate gases, such as carbon dioxide, carbon monoxide, ozone, nitric oxide, etc., which are directly sucked away by strong suction. If the surface of the customer's product is indeed dusty and stained, it is best to wipe off the surface residue first, or wash it with water before using plasma cleaning.
In a non-dust-free environment, how long can the surface last from cleaning to the next process?
How long the water drop angle is maintained is related to the humidity and oxygen content in the environment. Oxygen will form a film on the surface of the product and be oxidized. Different substances are oxidized at different speeds, so the maintenance effect depends on the different materials. It is recommended to proceed to the next step directly after cleaning. If it really needs to be placed, it can be placed in a nitrogen cabinet.
