Abstract
A printed circuit board having electrical components connected thereto in spaced relation is coated with a resin material by immersion in a container of resin material. The flow of resin between the electrical devices and the circuit board is facilitated by the provision of holes through the circuit board in alignment with each electrical component so that the formation of blow-holes is prevented.
