SPA-3600 atmospheric plasma cleaning machine is equipped with the jet direct spray gun head independently developed and designed by Shengding. It mainly deals with materials with small area, high tracking accuracy and many corners, improving the surface adhesion of the material and enhancing the bonding strength and other issues.
working principle

Under the excitation of the high-voltage power supply, the compressed air, oxygen and other process gases are ionized in the atmospheric environment to generate plasma, and directly act on the surface of the product for cleaning. Through atmospheric plasma treatment, the surface activity of the material is improved and the surface adhesion is improved.
The structure of the plasma cleaning machine is mainly divided into three major components, which are the high-voltage excitation power supply, the plasma generator spray gun, and the control system.
（A）High voltage excitation power supply:The generation of plasma requires high-voltage excitation, and the atmospheric plasma is excited by an intermediate frequency power supply with a frequency of 10-40KHz. The high voltage is 4-10KV. The parameters can be adjusted according to the actual situation of the sample, and the modified effect has been achieved.
（B）Plasma generator spray gun:Atmospheric plasma generator spray gun, according to the size of the processing area, the plasma spray gun can be divided into two types: jet direct injection and rotation.
Jet straight nozzle:
1. Optional nozzle: ① Ordinary jet direct injection ② Flat nozzle jet direct injection
2. Ordinary jet direct injection optional specifications: 2mm, 3mm, 5mm, 10mm
3. Flat nozzle jet direct injection optional specifications: 10mm, 15mm
Rotate the muzzle:
1. Ordinary gun mouth: 20mm, 30mm, 50mm, 70mm
2. Muffler nozzle: 20mm, 30mm, 50mm, 70mm
(C) Control system:The role of the control system is to control the operation of the entire atmospheric low-temperature plasma cleaning equipment and the protection of the overall system.


Industry application


Industry-specific solutions
Electronic circuit industry application
HDI board:After laser drilling, plasma cleaning is performed to remove carbides, etch and activate via holes to improve the yield and reliability of the PHT process.
FPC board:It can effectively remove the resin residue on the hole wall of the multi-layer flexible board, increase the surface roughness, improve the surface wettability, and increase the quality of welding and dispensing.
Rigid-flex board:Removes debris inside the perforations and improves surface adhesion.
Teflon board:Clean and activate the hole wall and the material surface to improve the bonding force between the hole wall and the copper-plated layer, and improve the adhesion between the solder mask ink and the silk screen characters.
BGA placement：Clean and activate the Pad surface to improve the yield of BGA placement.
