The primary function of conformal coating is to prevent the electronic circuit boards from long-term corrosion due to moisture condensation. Other desirable features include a better prevention of electrical shorts in high humidity days.
Having a sealed electrical box is good for rain. Moisture can still pass through the plastic boxes and rubber gasket.
Sealed boxes do not “breathe” and thus trap moisture that cannot escape and will condense to become sitting water inside the box at night or in colder weather. Condensed with potentially contaminating ionics from the air is one of the most potent corrosive ingredients.
Per IPC-A-610 Traditional conformal coatings such as polyurethane, acrylic, and silicone should be:
|25.4 – 127.0um (0.001– 0.005 in)
|25.4 – 127.0um (0.001-0.005 in)
|25.4 – 127.0um (0.001-0.005 in)
|50.8 – 203.2um (0.002 – 0.008in)
|10.2 – 50.8um (0.0004 – 0.002in)
Conformal coating is not designed as physical protection media.
General mechanical strength is not required. As long as the conformal coating remains intact at low and high temperatures, low and high humidity, and resists water and common chemicals and solvents, they will be effective conformal coating.
Dielectric strength is a measurement of the insulation strength of the coating. Generally higher the better.
However, the circuit boards are supposedly designed to have adequate protection against normal operation. As long as the conformal coating does not negatively affect the dielectric strength in air, they generally will be adequate.
Brush coating is used for smaller-volume production. It has the advantage of applying conformal coating only on those needed areas. Labor with such a method is higher.
Spray coating is used for larger volume production and is generally faster. However, areas that must not be coated must be properly masked before coating.
Dip coating is used for those requirements that need complete coverage. Extensive masking is required because the boards will be fully submerged. This method is costly.
The typical masking method is taping with dots, high temperature tapes, boots and various peelable masks. The reason I put this in is because liquid latex masks are only one of many peelable mask that we use.
