Plasma PCB circuit board processor (plasma cleaning machine):
1. Remove PCB circuit board in the mechanical drilling and laser drilling in the high temperature caused by polymer melt in the cell wall surface of the plastic metal slag, especially for chemicals difficult to drill a hole into the laser application.
2. Processing PTFE sheet, to increase coating adhesion strength.
3. In soft or rigid circuit board, and HAL in the pre-clean laminated surface and improve adhesion.
4. Clean gold contacts, to improve the wire bonding strength.
5. In the package before or poly-diphenyl-coating before the activation of electronic components.
6. In copper processing, before the insulating film capacitors for processing.
7. Deposited in the weld area to remove residual coating line in order to improve adhesion and welding.
Advantages:
1. Environmental Technology: Plasma process is gas - solid coherent reaction, no consumption of water, without adding chemicals, environmental pollution, can replace the chemical treatment process solution of sodium naphthalene.
2. Temperature is low: Close to room temperature, particularly suitable for polymer materials, polymer materials involved only shallow surface (10-1000A), damaging the material is less than the chemical process.
3. Low Cost: The device is simple, easy operation and maintenance, continuous operation, usually a few bottles of gas, we can replace thousands of kilograms of washing liquid, no liquid waste processing costs, processing costs will be significantly lower than the wet chemical treatment.
