Abstract
An apparatus and method for applying a conformal coat to an electronic assembly which significantly reduces the emissions which are a by-product of the process. A spray gun atomizes a conformal coat/solvent mixture at a high pressure within the gun and then emits the mixture at a low volume and low pressure such that the transfer rate of the material is very high and the amount of wasted material is very low. The coats are applied in such a manner that the electronic assembly can be sprayed multiple times before sending the entire assembly into the curing oven.
