Title:
LIQUID CRYSTALLINE RESIN COMPOSITION FOR SURFACE-MOUNTED RELAYS AND SURFACE-MOUNTED RELAY USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/116888
Kind Code:
A1
Abstract:
Provided are a liquid crystalline resin composition for surface-mounted relays, that provides a molded article that has excellent heat resistance, suppressed blister occurrences and filler desorption, and is capable of being adhered at a high adhesion strength by an adhesive; a component for surface-mounted relays, using same; and a surface-mounted relay. This liquid crystalline resin composition for surface-mounted relays includes a liquid crystalline polymer (A) and a fibrous filler (B). The liquid crystalline polymer (A) is a wholly aromatic polyester amide comprising a prescribed amount of constituent units (I)–(VI) as essential constituent components thereof and exhibiting optical anisotropy during melting. The fibrous filler (B) has a weight-average fiber length of 50–170 µm and contains at least 70% by mass of a fraction having a fiber length 20–200 µm. The surface-mounted relay comprises a base and a terminal protruding from the base. The terminal is soldered on to a printed circuit board.
