DEVICE FOR APPLYING PASTE OF DIE BONDING MACHINE

摘要

PURPOSE: A paste applying apparatus for a die bonding machine is provided to reduce vibration caused by high speed by forming a linear and arc shaped transfer path for an applying pin to apply paste along a rotational direction of a rotating arm. CONSTITUTION: A servo motor(10) provides transfer force to an applying pin(30). A rotating arm(20) is installed to be eccentric on a rotary shaft of the servo motor. The rotating arm lets the applying pin to travel back and forth to a past applying portion on a paste disc(50) and a lead frame(60) pad. A fixing portion(31) fixes the applying pin on an end portion of the rotating arm. The applying pin coats paste on the lead frame for die bonding.
