Instruments of this group are the most wide-spread and universal and are intended for use as a part of semi-automatic and automatic installations of thermocompression and ultrasonic welding of wire and ribbon leads as an instrument for ultrasonic welding semiconductor devices and integrated circuits.
Depending on the requirements set for welded joint and used welding equipment, domestic industry has developed and successfully applies a great number of different types of instruments with side-cut capillary port – KT3, KU9, KUT2, KUT3M, KUT4, KUT5, KUT6, KUT7, KUT8, KUT9, KUT10, KUTI, KUT14, KUT18M, KUTC. These instruments are used for welding “overlapped” of wire lead of diameter from 0.020 up to 0.500 mm and ribbon leads (KUT5) with the dimensions from 0.016*0.040 up to 0.050*0.500 mm.
Physically instruments are a cylindrical stem with wedge-shaped working part consisting of square shaped working area and capillary port guiding the welded wire or ribbon into the working area at a certain angle.
High treatment frequency and dimensional accuracy of working parts permits high-speed welding and insures good instruments working capacity.
Material for instrument production: hard alloy.
