IMPERMEABLE PROTECTIVE COATINGS THROUGH WHICH ELECTRICAL CONNECTIONS MAY BE ESTABLISHED AND ELECTRONIC DEVICES INCLUDING THE IMPERMEABLE PROTECTIVE COATINGS

摘要

Protective coatings are disclosed that are configured to cover electronic components within an electronic device, while enabling electrical connections to be established with electrical contacts that are covered by the protective coatings. Such a protective coating may comprise a parylene, or a poly(p-xylylene), protective coating that has a thickness of at least 0.1 μm and at most about 2 μm. Electronic devices that include such a protective coating are also disclosed.

主权项

1. An electronic device, comprising:
a housing defining an interior of the electronic device; at least one printed circuit board within the interior of the electronic device; a plurality of electronic components assembled with but not carried by the at least one printed circuit board; and at least one coating comprising a poly(p-xylylene) on at least portions of the at least one printed circuit board and the plurality of electronic components, the at least one coating being thin enough to enable electrical connections to be made therethrough as conventional interconnection processes are employed.
