Sensor with Polymer Substrate for use in Corrosive Liquids

摘要

A fuel system sensor (16) has an acetal substrate (22) that does not corrode in fuel, and the substrate (22) bears conductors (24, 26) that are connected to terminals (28) partially embedded in the substrate (22). Various methods for forming the conductor paths on the acetal are disclosed. The terminals (28) can be formed with thermal relief structure (34-38).
