Adding Acrylic Conformal Coating to Your Printed Circuit Boards
Acrylic resins (AR) are single component materials. To specify, they are preformed acrylic polymers that are dissolved in a solvent to be applied to surfaces. One main benefit of using an Acrylic conformal coating service on your electronics is it provides an excellent barrier to moisture/humidity and have good fungus resistance. They also have minimal chemical resistance which makes it ideal for reworking and removability.
Acrylic Conformal Coating
can be easily applied with a brush, sprayed or by dipping. For smaller batch productions, such as prototyping, hand brushing is commonly. For those large batch groups, spraying the coating on is best because it gives you an accurate control of coating. Dipping is achieved by placing the assembly into a vat of the coating. This procedure is also well suited for small batches.
No matter where your electronic device is meant to be used, chances are high that there is at least one major atmospheric threat that can harm the delicate circuit boards within.
made of acrylic resin (AR) are very popular choice because it protects printed circuit boards (PCBs) and other electronics from corrosion, dirt, dust, fungus, moisture, and thermal shocks.
Acrylic conformal coating currently makes up 80% of the market. The purpose of conformal coating is to protect the sensitive circuits in your device so that it can live longer and work better. What kind of threats does conformal coating protect against?
Moisture and Humidity
Moisture is a printed circuit board’s worst enemy. It can easily fry the circuit board, rendering it inoperable. Conformal coating may not be able to protect your device from a torrential downpour or a drop in the toilet, but it can resist humidity and condensation.
Dust
Dust can easily clog up a printed circuit board, especially due to electrostatic attraction. Conformal coating shields the inner workings of a circuit board from dust.
Heat and Cold
If your electronic device is meant to be used outside, then it will have to be able to withstand the sizzling highs and bone chilling lows of the environment. Conformal coating can protect against temperature extremes.
