Abstract

See full text

An electric drive (1) with a circuit board (2), having conductor tracks (3) and contact openings (4) with plated through-holes (5) and equipped with electronic components (6), the circuit board (2) being coated with a protective layer (7) of insulating material, and press-fit contacts (8) are inserted into the contact openings (4) and in electrical contact areas (9) within the contact openings (4) electrical contact exists between a press-fit contact (8) and the plated through-hole (5) of the contact opening (4). The task of the invention is to reliably protect circuit boards of electric drives exposed to moisture and other chemical environmental effects and contact them economically. This task is solved according to the invention in that the protective layer (7) is a parylene coating, which covers the circuit board (2), the electronic components (6) and the surface areas of the contact openings (4) and circuit board (2) directly connected to the contact areas (9) between at least one press-fit contact (8) and at least one contact opening (4).
