Abstract

PURPOSE: To improve the moisture resistance of all operating section, surface oxidation and an anti-pollution effect by surrounding a circuit part including the operating section by a case and previously closing an opening in the surface with a sheet when the circuit part including the operating section and circuit parts except said circuit part are set up onto the surface of a hybrid IC substrate.
CONSTITUTION: Circuit operating sections 2 building in circuit operating sections such as volumes 3 and circuit parts 4 having no operating section are fitted onto one surface of a hybrid IC substrate 1 from which a large number of legs 8 for inserting to a printed substrate are protruded. The operating sections 2 are surrounded by cases 5, and opening surfaces 6 in the cases are closed by silicone films 7. Bar bodies 10 are pushed against only the operating sections 2 first in order to prepare such a substrate, and the insides of the operating sections 2 are impregnated with wax and the bar bodies 10 are broken and removed. Accordingly, the operating sections building in the volumes, variable capacitors, variable inductances, etc. are prepared and assembled simply.
