ELECTRICAL CONNECTING ARRANGEMENTS

摘要

A process for protecting an electrical connecting arrangement (e.g. back-plane assembly) against deleterous environmental conditions by providing the arrangement with a conformal protective coating applied by dipping for example, in which prior to applying the conformal coating selected interstices of electrical connector(s) or other component(s) of the arrangement are at least partially filled with suitable masking material to prevent penetration of the conformal coating material into said interstices during the coating step and thereafter dissolving the masking material out of the latter.
