[0257] (Production of adhesive for circuit connection)

[0258] Compound thermoplastic resin, radical polymerizable compound and radical polymerization initiator, and boron-containing complex or amine compound according to solid mass such as shown in Table 1, and further, use adhesive agent (excluded from the adhesive for circuit connection) Based on the total volume of the components containing conductive particles), 1.5% by volume of conductive particles was mixed and dispersed to obtain an adhesive for circuit connection. The obtained adhesive for circuit connection was coated on a fluororesin film with a thickness of 80 μm by a coating device, and dried by hot air at 70° C. for 10 minutes to obtain a film-shaped circuit connection adhesive with an adhesive layer thickness of 20 μm. Adhesive.

Abstract

The invention relates to an adhesive composition, a film-like adhesive, an adhesive sheet and a connection structure, wherein the adhesive composition contains: (a) a thermoplastic resin, (b) a radical polymerized compound, (c) a radical polymerization initiator, and (d) a boron-containing complex. Wherein, the (d) complex is a compound represented by the following general formula (A), and in the formula (A), R1, R2 and R3 each independently represents an aryl group with or without a substituent, and X represents amine compound with nitrogen-atoms or a phosphorus compound with phosphorus atoms.

Description

technical field [0001] The present invention relates to an adhesive composition, a film-like adhesive, an adhesive sheet, a bonded structure, a method for producing a bonded structure, and an application of the adhesive composition. Background technique [0002] In semiconductor elements and liquid crystal display elements, various adhesives have been used conventionally for the purpose of bonding various components in the elements. Requirements for adhesives include many aspects such as adhesiveness, heat resistance, and reliability under high-temperature and high-humidity conditions. The above-mentioned adhesive is used for the connection between liquid crystal display element and TCP (COF), the connection between FPC and TCP (COF), the connection between TCP (COF) and printed circuit board, the connection between FPC and printed circuit board, etc. Moreover, the said adhesive agent is also used when mounting a semiconductor element on a board|substrate. [0003] As an a...
