MOISTURE RESISTANT STRUCTURE OF MODULE CIRCUIT

摘要

PURPOSE:To provide the entitled moisture resistant structure of a module circuit capable of securing the moisture resistance almost without changing the electric circuit characteristics of strip line easy to form a high-frequency circuit. CONSTITUTION:Within the entitled moisture resistant structure of a module circuit, a strip line 2 of a module board 1 having a high-frequency circuit and a high-frequency device is to be covered with a water repellent porus film 3 in apparent (air bubble containing state) dielectric constant of not exceeding 2.0.
