Abstract
PURPOSE: To obtain the title insulator usable for printed circuit base boards, having improved solder resistance, by heat-treating a molded article comprising polyphenylene sulfide resin at a temperature ranging from the softening point (T) of the resin to (T-30°C).
CONSTITUTION: Polyphenylene sulfide resin is kneaded with a filler, e.g. glass fiber, a silane coupling agent, etc. to form a molding composition, which is injection molded into an article of desired shape. The article is then heat-treated at a temperature of the softening point T (about 277°C) to (T-30°C) for about 0.5W50 hr. The heat resistance, such as solder resistance, is remarkably improved, scarcely deteriorating the high-frequency characteristics and chemical resistance.
