What are conformal coating characteristics?

Conformal Coating should ideally possess as many of the following characteristics as possible:

One-part product
Low viscosity
Spray, dip, select, or flow-coat application options
Long pot life
Rapid cure, no by-product
Sufficient under-component cure
Repairability
Wide range of operating temperatures
Non-toxic
Low cost
Robust adhesion

Potting & Conformal Coating


Alpha Electronics Manufacturing can produce a variety of coating and encapsulation processes of pcb’s, connectors and boxes for their quality assured electronics solutions to meet with your specific requirements. Conformal coatings protect pcb’s from moisture and contaminants, preventing short circuits and corrosion of conductors and solder joints. They also minimise dendritic growth and the electromigration of metal between conductors. The use of conformal coatings protects circuits and components from abrasion and solvents. Stress relief can be provided, as well as protection of the insulation resistance of the circuit.



Potting and conformal coating can produce protection from environmental hazards, Increased reliability and resilience.

Specializations

Capitalise on low hanging fruit to identify a ballpark value added activity to beta test. Override the digital divide with additional clickthroughs from DevOps. Nanotechnology immersion along the information highway will close the loop on focusing solely on the bottom line.

Potting and conformal coating aid to prevent circuits from failing in harsh environments or from vibrations and other potentially damaging uses. It increases the electrical performance of a circuit board through shielding and both methods can be effective when used in the right situation. Potting should be used for impact resistance and can also be used to obscure identification of the components used within a design.



Alpha’s preferred material to use for conformal coating is an Acrylic coating – Humiseal 1B73 which is applied by either brushing or spraying under our BV200H-D Bench Vent extraction hood.

Parylene coating can be offered by using a 3rd party specialised in the application. Parylene is a polymer coating used for protecting various circuits in the Medical and Aerospace industries.
