Abstract

PURPOSE:To improve insulation and reliability by applying an adhesive on the peripheral edge of surface mount parts before impregnating a hybrid IC in resin power and rounding off the corner part of the printed board. CONSTITUTION:A hybrid IC 1 is constructed by allowing terminal forming discrete parts 3a such as a power transistor connected with a terminal 6 to be packaged on a printed circuit board 5 as surface mounting parts 3. First, an adhesive 4 is applied on the peripheral edge of the surface mounting parts 3 before impregnating the hybrid IC in resin powder. Thereupon, the adhesive 4 is applied on the peripheral edge of the surface mounting parts 3 which is tall preferentially. In addition, the corner part 5a of the printed circuit board 5 is rounded off. Thereafter, the hybrid IC is heated over about 150 deg.C its surface by a heater and the like. In succession, the hybrid IC is impregnated in resin powder such as epoxy resin powder and coated with the resin powder. This is repeated 3-4 times. Finally, it is again heated over 150 deg.C by the heater to form a resin-coated film 2, thereby sealing the hybrid IC 1 with the resin.
