Abstract

A printed circuit board 1 has a cover 2 secured thereto by vacuum forming to prevent shorting of electronic components on the printed circuit board 1 through foreign particles falling onto the printed circuit board 1. A cover 2 is preferably formed of a relatively flexible sheet of styrene or other similar material having a thickness of about one to two mils. If the cover 2 is not thin enough to enable cooling of electrical components on the printed circuit board 1, the cover 2 has small holes 3 formed therein. The cover 2 also may be of a dark color, such as charcoal, to enable quicker cooling. The cover 2 has openings 4 therein to enable reception of connectors 5 on the printed circuit board 1.
