摘要:
The bonding apparatus comprises: a substrate supporting section (5) for supporting a substrate (1), on which semiconductor devices (3) have been adhered, in a state where the substrate (1) is separated from a clamping face (6a, 17a) of a second die (6, 17); and a heating/pressing section (10, 28) for heating and pressing the substrate (1) supported by the substrate supporting section (5) onto a clamping face (10a, 28b) of a first die (8, 24). The heating/pressing section (10, 28) moves the substrate (1) toward the clamping face (10a, 28b) of the first die (8, 24) so as to preheat the substrate (1) and the semiconductor devices (3). The semiconductor devices (3) are pressed onto the clamping face (10a, 28b) so as to cure the non-conductive adhesive (2) and bond the bumps (3a) of the semiconductor devices (3) to terminal sections (1a) of the substrate (1).

An anisotropic conductive film (14) and circuit devices (16) are superimposedly overlaid on a substrate (10). The circuit devices are pressed isostatically by a press die having a soft layer (22) on the surface to be brought into contact with the circuit devices and heated simultaneously to compression-bond the circuit devices to the substrate. Since the soft layer absorbs the differences in the thickness of the circuit devices, the circuit device can be pressed simultaneously. Furhter, since the circuit devices are heated simultaneously, it is unnecessary to consider the influence of the heat on the unheated adjacent circuit devices. The isotropic conductive film does not overlap sideways because of the isostatic press. As a result, the spaces between the circuit devices can be small.

In a heat insulating load jig 11 of the present invention, a solder material 14 having a melting point or a solidus temperature in a range between a thermal resistance temperature of a semiconductor chip 13 and a temperature 100°C below the thermal resistance temperature is interposed between a circuit board 12 and the semiconductor chip 13; a heat insulating body 17 is placed on an upper side of the semiconductor chip 13 in this state; a metal weight 16 is disposed on the heat insulating body 17; and load is applied to the semiconductor chip 13 while the solder material 14 is melted and solidified.
摘要:
A compression bonding device capable of packaging electric components on both sides of a substrate is provided. A compression bonding device 1 includes first and second pressing rubbers 15, 25. Electric components 32, 33 can be simultaneously packaged on the front face and the rear face of a substrate 31 by sandwiching the substrate 31 between the first and second pressing rubbers 15, 25. The electric components 32, 33 are not subjected to a force for horizontally moving them because the first and second pressing rubbers 15, 25 are prevented from horizontal extension by a first dam member 16. Thus, the electric components 32, 33 are connected to the substrate 31 without misalignment, thereby obtaining a highly reliable electric device 30a.

摘要:
A compression bonding device 1 of the present invention has a dam member 24 so that when a pressing head 20 is pressed against an object to be pressed 10, the bonding part 22 is surrounded by the dam member 24. Thus, even if the surface of the bonding part 22 bulges by pressing, the bulging part is stopped by the dam member 24 and the surface of the bonding part 22 does not horizontally extend. As a result of the absence of horizontal extension of the bonding part 22, electric components 16, 18 of the object to be pressed 10 are not subjected to a force that horizontally moves them and the electric components 16, 18 are vertically pressed downward and connected to the terminals 12 of the substrate 11. Thus, an electric device 10a having high connection reliability is obtained.
