| Does anyone have any figures on what % extra compnents should be supplied on chip components for a particular product build. Typicaly there is wastage due to dropout in loading, 1st board build and machine rejections. Is there any industry standard

| We have a new custumer that needs thier thru-hole/smt boards conformally coated. We currently do not have a selective spraycoating system adn this low volume of these board do notwarrant a 100k machine. We are spending way to much time masking and
