PCB Protection

Protecting the PCB board in critical applications which are exposed to harsh environmental working conditions is essential if product failure is to be avoided. Two methods are generally used-conformal coating and potting/encapsulation. A conformal coating is normally applied as a thin layer across the surface of the board, covering all components and delicate wiring.
For a coating to be effective it must have good adhesion to all the components and substrates, be unaffected by changes in operational temperature and be resistant to any contaminants, such as moisture and chemicals. Its ability to flow around, under and over the components without leaving areas exposed to the atmosphere especially on sharp edges, is also important.
Contin offers a series of eco-friendly conformal coating including 100% solid content conformal coating material such as silicon based material, UV/moisture curing material with a UV indicator to enable easy visual quality control inspection under a UV light source.

Key features
● Wide operating temperature range (-55 ºC to + 200 ºC)
● room temeperature, UV or heat cure
● Low viscosity
● 100% solids (no harmful solvents)
● Excellent adhesion to many substrates
● Low odor
● RoHS compliant
● Not flammable
● Workable just after touch dry time without fire risk

Attentions:

● Cured coating thickness is between 0.025mm to 0.10mm. 0.05 mm thickness (±0.01 mm) will give the best protection against the environmental requirements of MIL-I-46058.
● Boards and components MUST BE CLEAN, OIL-FREE, AND DRY.

Contin focus on the new eco-friendly conformal coating material for the electronic industry and developed different kinds of 100% solid content coating material based on different technology.
