PCB coating - conformal coating –
selective coating - protective coating
The increasing demands placed on electronic assemblies in terms of quality, service life and reliability require more and more protection from environmental influences.
For low-cost applications or high-end areas, we can offer our customers suitable processes. Together with our customers, we specify how much protection is needed for each application.
Coating prevents:
- Leakage currents, short circuits due to moisture and impurities
- Corrosion
- Arcing and corona discharge
- Damage caused by mechanical shocks and vibrations
- Fungal infestation
The following types of coating are possible:
- Selective conformal coating (Painting system: Nordson Asymtek automatic coating machine)
- Dip painting
- Manual coating
Description conformal coating method/ Selective conformal coating method:
The printed circuit boards are coated with a coating film process under low pressure selectively, without spray mist and with extremely high precision. The coating material is removed from a heated paint conveying system, which works with pressure loading and not with compressed air.
The monitored paint curtain creates very precise contours and there is no overspray.
