by

Transcend has announce that they are now offering conformal coating coating as a customization option on their full range of embedded-use flash and DRAM products.

Transcend Now Offers Conformal Coating

Conformal coatings can be done in several ways which includes manual brushing, manual spraying, dipping, and by automated spraying machines. Although dipping sounds like a fast and easy option to go with, it doesn’t give you the best of uniformity of coating, possibly the worst of options when it comes to uniformity. As you can expect, Transcend utilizes automated spraying machines due to their speed and of course the most important part, accuracy.

With these methods, each has its own strengths and weaknesses and it’s important to get it right as the coating which encapsulates the entire printed circuit board (PCB) provides a physical barrier against moisture, dust, and other environmental contaminants. Commonly, most coating materials are acrylic, silicone, urethane, and epoxy. Silicone and epoxy coatings can withstand exposure to high temperatures, while urethane is chemical resistant. Acrylic coatings are the preferred choice as they offer good moisture and electrical resistance.

Transcend offers an acrylic conformal coating solution, which is supplied by HumiSeal. The coating offers fast drying and offers flexibility, moisture protection, electric isolation, and is well suited to most applications. The coating is applied directly to the surface, except for the gold-fingers area. Not surprisingly, Transcend recommends to have conformal coated flash and memory modules, especially for those in harsh environments with high moisture, high dust, or chemical contaminants.
