Erni Electronics unveil customised coating solutions

Erni Electronics recently expanded its service offering for electronic boards and assemblies, announcing three different coating processes that prevent functional impairments.

The Fluoro polymer coating provides a protective layer thickness of approximately 1 micron. It is based on the complete immersion of the assembly in the coating bath without masking off metallic contact surfaces. In the event of contact, the protective layer is pierced. Assemblies can be repaired following coating.

Selective Thin Film coating is a fully automated lacquer curtain coating process. The surfaces to be coated (select coat process) can be individually programmed. The fluorescent protective layer simplifies the optical inspection.

Selective Thick Film coating provides protective layer thicknesses up to 2mm. Therefore an additional sight proofing and protection against Contact is reached. It also enables a secure application of "boundaries", that can be filled with pourable lacquers (dam & fill process).
