Abstract

PROBLEM TO BE SOLVED: To provide a thermocompression apparatus that is capable of bonding a plurality of types of chips to the board of a liquid crystal panel or the like by thermocompression using one and the same nozzle. SOLUTION: A plurality of suction holes 16 are formed on the underside of a nozzle 14, which vacuum-sucks a plurality of types of chips (a first chip 10A and a second chip 10B), different in dimensions and shape, and bonds them to the electrodes on the board of a liquid crystal panel or the like by thermocompression. The suction holes 16 are formed in an area shared between the first chip 10A and the second chip 10B so that both the first chip 10A and the second chip 10B can be vacuum-sucked. This makes it unnecessary to change the nozzle 14, and makes it possible to bond a plurality of types of chips to a liquid crystal panel by thermocompression with favorable workability.
