Abstract:
A method of pressure bonding a bumped electronic part to a substrate, said method using a suction tool, a tilting mechanism for tiltably supporting said suction tool, and locking means for inhibiting a tilting operation of said tilting mechanism, said method comprising the steps of:sucking the bumped electronic part to said suction tool;leveling the bumps of the bumped electronic part which is sucked to said suction tool;detecting positions of the leveled bumps on the bumped electronic part by partially collapsing the bumps;positioning the leveled bumps of the bumped electronic part with respect to the substrate when the tilting operation is inhibited; andpressure bonding the leveled bumps of the bumped electronic part, which is sucked to said suction tool, to the substrate when the tilting operation is permitted.
