Problems solved by technology
[0006] However, in such prior art, since the connection portion between the IC chip and the substrate, that is, the pressing force between the bump and the pattern is insufficient, sufficient connection cannot be made, and there is a problem that the initial on-resistance cannot be ensured sufficiently. and connection reliability issues after aging
[0007] In addition, in the method of applying pressure and heating using a thermocompression joint made of an elastic body, there is a problem that the IC chip and the substrate are misaligned during pressure bonding.
[0008] And, in this way, especially in the case of collectively mounting a plurality of IC chips, the above-mentioned misalignment tends to increase.

The present invention provides a mounting device capable of highly reliable mounting a plurality of electrical components using an adhesive agent. The present invention is a mounting device including a thermocompression bonding head 4 having a pressure bonding member 6 made of a predetermined elastomer provided in a head main body 5, and the mounting device is constructed such that an IC chip 20 placed on a wiring board 10 is pressed by the pressure bonding member 6 at a predetermined pressure, and further includes a pressing force adjusting mechanism for adjusting pressing force corresponding to a region on a pressure bonding surface 6a of the pressure bonding member 6. A pressing force adjusting mechanism can be used in which a plurality of pressing force adjusting frames 5a are provided in the head main body 5, and the pressure bonding member 6 is disposed inside these pressing force adjusting frames 5a.
Description
technical field [0001] The present invention relates to a technique of mounting electrical components such as semiconductor chips on a wiring substrate, and more particularly relates to a technique of mounting electrical components using an adhesive. Background technique [0002] Conventionally, as a method of directly mounting a bare chip on a wiring board such as a printed wiring board, a method using an anisotropic conductive adhesive film in which conductive particles are dispersed in an adhesive is known. [0003] In the mounting method using an anisotropic conductive adhesive film, after the IC chip is mounted on the substrate on which the anisotropic conductive adhesive film is pasted, the IC chip is mounted on a flat crimping head made of ceramics or metal. Apply pressure and heat to cure the anisotropic conductive adhesive film and perform thermocompression bonding. [0004] In the case of such a method of pressurizing and heating using a crimping head such as a me...
