Abstract

PURPOSE:To enable the use of a low heat resistnat part by containing a thermosetting resin pellet of incompletely cured state in a box-shape case for mounting the part and melting and hardening the pellet with its seal directed downwardly, thereby facilitating an assembling work. CONSTITUTION:A base block 7 passed with a terminal 8 therethrough is formed in a shape engaged with a box-shaped case 1, and is used as a cover 5. A printed board 10 mounted with a part 2 is soldered fixedly to the end of the terminal 8, and is contained in the case 1 together with a resin pellet 4 formed in air gap shape of the part with a cover 5 directed downwardly. The pellet 4 is secured with power, e.g., epoxy or the like in semi-hardened state, is allowed to stand at 80 deg.C for 20- 30min to be molten to bury the leads of the printed board 10 and the part 2 and to be then hardened, and the gap between the case 1 and the base block 7 is sealed. In this manner, assembling can be facilitated including the inspection of the characteristics, and can be sealed at low temperature, thereby enabling the use of the low heat resistant part.
