Abstract

PURPOSE:To prevent the swelling and moistening of the sheating material of an electrolytic capacitor by covering the electrolytic capacitor beforehand with epoxy resin that does not contain any organic solvents, hardening it, and after that covering the whole hybrid integrated circuit with low-viscosity epoxy resin. CONSTITUTION:After each part including an electrolytic capacitor 1 is mounted on a substrate 4, the electrolytic capacitor 1 is partially covered beforehand with epoxy resin 2 that does not contain any organic solvents, and the resin 2 is hardened. After that, the whole hybrid integrated circuit is dipped in liquid epoxy modified phenol resin with low-viscosity, for example, and the attached resin is heated and hardened to form sheath-coating 3. As the electrolytic capacitor 1 has been covered and protected partially be forehand with epoxy resin in this way, the organic solvent contained in the epoxy modified-phenol resin does not come into contact with the electrolytic capacitor 1 directly. Besides, the resin creeps into the whole hybrid integrated circuit well as the viscosity is low.

However, in such conventional dip coating, a large amount (20% 50%) contains an organic solvent. Therefore, the component parts of the hybrid 4J product circuit, especially the electrolytic capacitor 1, have their exterior materials swollen due to the chemical influence of the organic solvent, pushing up the resin 3 covering the outside and causing cracks after dip coating. Occurrence or peeling occurred.

In order to solve one or more of the above problems, in the present invention, in a hybrid integrated circuit including an electrolytic capacitor, the electrolytic capacitor is coated and cured in advance with an epoxy resin that does not contain an IRIS agent, and the entire I&hybrid integrated circuit is coated and cured. This invention proposes a method for manufacturing a hybrid integrated circuit characterized by coating it with a low-viscosity epoxy resin.

In this manufacturing method, the fluid epoxy-modified phenolic resin before curing contains a large amount of organic solvent in order to lower its viscosity, but even though it contains a large amount of organic solvent, Since the electrolytic capacitor 1 is locally covered and protected with the epoxy resin 2 in advance, the organic solvent contained in the epoxy-modified phenol resin in the subsequent process does not come into direct contact with the electrolytic capacitor, and at the same time, its viscosity is low and the mixture is The resin spreads well into the entire integrated circuit. Therefore, the finish of the exterior covering of the hybrid 4Jg4 circuit is maintained well, and the exterior material of the electrolytic capacitor 1 is not swollen due to the chemical influence of the organic solvent.

As described above, in the present invention, since the electrolytic capacitor on the hybrid integrated circuit is coated and protected in advance with a resin that does not contain organic solvents, the organic solvent contained in the epoxy-modified phenolic resin surrounding the outside of the electrolytic capacitor is protected. Do not touch electrolytic capacitors directly. Further, although the electrolytic capacitor is a large component among the components of a hybrid integrated circuit, since it is fixed to the substrate in advance with resin, the boundary portion with the substrate is firmly fixed with the resin. Therefore, the finish of the exterior covering of the hybrid integrated circuit is maintained well, and the exterior material of the electrolytic capacitor 1 is not wetted by the chemical influence of the organic solvent.
