The coating method and system of water based conformal coating for VOC.
A water-based conformal coating material without an environmental impact is fully coated in a detailed space part, the construction method which can form the uniform coat side by the selective coating which uses water-base material is developed.
The means for solving a subject.
Water based conformal coating material
Viscosty=20~200mPas、
Solid content=25~60%(Volume)
- It coats to a substrate by the low flow rate spray valve which has a nozzle of 0.5mm OD or less with a star-shaped form air cap + super thin needle.
- Using the stitch control for pulse coating.→Shortening of drying time.
