摘要:
In a bonding tool which bonds a component to a substrate by urging and vibration, a through hole is formed in the horn. An adhesion section is fit into a lower section of the hole and an engaging section is fit into an upper section of the hole, so that a sealed inner space is formed inside the hole by tightening an outer screw. An adhesion hole open to a bonding section communicates with a sucking hole of the horn via the inner space, so that a simply structured vacuum-adhesion-system can be formed. These mechanics do not lose replaceablility of the adhesion section detachable to the horn. As a result, the adhesion section can be replaceable as an independent part (urging terminal), and a bonding apparatus as well as a bonding tool having the simply structured vacuum-adhesion-system can be provided.

An apparatus and a method for mounting a chip make it possible to accomplish quick chip mounting and also to mount multiple different chips on substrates. Three heads are provided around a center rod of a head assembly; they horizontally rotate around the center rod. When the heads rotate horizontally, they are turned 180 degrees vertically by a first bevel gear and a second bevel gear. A nozzle of one of the heads picks up a flip chip from a wafer sheet and rotates 180 degrees horizontally to transfer the flip chip to a transferring head, during which it vertically inverts 180 degrees so as to vertically invert the flip chip. The transferring head receives the flip chip from the head and mounts it on a substrate. According to the type of chips to be mounted, the heads and the transferring head are equipped with nozzles best suited for the type of chips.

A structure for mounting a SAW (Surface Acoustic Wave) device includes photosensitive resin filling a gap between the SAW device and a mounting substrate in the peripheral portion of the SAW device. The entire structure is substantially as small in size as the SAW device and light weight. The photosensitive resin is formed in a region including pads for connection in order to absorb thermal stresses and extraneous forces apt to act on the pads. Second resin may surround the photosensitive resin or may be provided in a laminate structure together with the photosensitive resin so as to enhance a sealing ability. A method of mounting a SAW device is also disclosed.

Solder balls are attached to a flexible printed-circuit board which is shaped so as to be able to cover at least an upper surface, a side surface, and a lower surface of an IC chip, and the flexible printed-circuit board is placed on the IC chip. Then, the flexible printed-circuit board is folded over edges of the IC chip, and bonded to outer surfaces of the IC chip by an adhesive sheet. Thereafter, a sealing resin is poured into a gap between the upper surface of the IC chip and the flexible printed-circuit board, and cured, thereby completing a semiconductor package.
