Reliable protection of PCBs
Surfaces of electronic components are increasingly being protected against environmental influences and/or corrosion by a thin layer of resin. The aim is to increase the service life and functional safety of the components.
The primary factor in conformal coating is the complete wetting of the component, including electrical contact points and solder connections. The different material viscosities that need to be processed here require an integrated preparation and feed system that can be specifically adapted to each material viscosity.
Overview of standard requirements
Our proven system solution
Our proven system solution for applying sealing varnishes and resins comprises the LiquiPrep LP804 material preparation and feed system, a Dos P016 dispenser and the DP803 DispensingCell. The material preparation/feed system and the dispenser are specially designed for the preparation and processing of sealing varnishes. The previously prepared material is conveyed from the material preparation and feed system via material feed lines to the dispenser. Precision sealing of the component in three dimensions is ensured by the dispenser mounted on the CNC axis system of the dispensing cell.
