Ruggedization of Electronic Circuits? Encapsulation is One of The Best-kept Protection Secrets
While conformal coatings increase the lifetime of electronic devices by providing a thin barrier that strengthens their ability to withstand harsh environmental conditions, adhesives and encapsulants provide a significantly higher level of protection on the entire assembly.
The most common properties of adhesives and encapsulants include:
- creating environmental seals that protect against moisture and corrosion,
- providing high-temperature resistance,
- increasing shock and vibration dampening,
- generating strong bonds to a variety of substrates,
- maintaining low shrinkage, and
- offering thermal conductivity.

When conventional coating methods such as hand spray, total dipping or robotic selective coating don’t provide the protection required, there is always selective dip coating.
What is selective dip conformal coating?
Selective dip coating is a process whereby the substrate rather than globally immerised in the coating, is discreetly coated in desired locales. The technique in one form or another, has been around for over 25 years and is used with both classic solvent-based coatings and 100% UV cure conformal coatings.

Easy Techniques to Abate Conformal Coating Wicking
Have you ever experienced uncontrolled conformal coating migration? Have you had to strip your recently coated boards because conformal coating wicked into non-desired keep out zones? Wicking is a phenomenon caused by a combination of low surface tension coating, which is usually characterized by low viscosity, coupled with strong capillary forces generated by low standoff gaps possessed by the SMT process. Wicking into connectors; onto grounding hole; or under sensitive components will create defects that will have to be reworked, as it may cause reliability concerns with the finished product, which we will describe in detail. There are ways to either reduce and/or eliminate wicking issues through decisions made during preparation, application, and conformal coating selection.
