Problems solved by technology

In addition, the mounting of SMD201 requires individual temporary mounting (temporary pasting), which requires a considerable amount of work.
[0009] In addition, although it is conceivable to use the same ACF to mount SMD, FPC, and IC at the same time, it is difficult to uniformly mount these electronic components with high precision because the ACF characteristics required for SMD, FPC, and IC are different.
For example, when temporarily mounting a small SMD such as a capacitor on an ACF for COG (adhesion: 5 to 80kPa), as in Figure 8 shown, misalignment of the SMD will occur

Abstract

Electronic components of different sizes are simultaneously mounted with high precision. The disclosed film has a two-layer configuration of a first resin layer (11) having a tack strength of at least 200 kPa, and a second resin layer (12) containing conductive particles. By means of electronic components being installed in the first resin layer (11), use on an IC, FPC, and SMD becomes possible, and simultaneous mounting becomes possible.

Description

technical field [0001] The present invention relates to an anisotropic conductive film in which conductive particles are dispersed and a method for producing the same. [0002] This application claims priority based on Japanese Patent Application No. Japanese Patent Application No. 2009-225771 filed on September 30, 2009 in Japan, and by referring to this application, it is incorporated in the present application. Background technique [0003] Until now, when bonding an IC (Integrated Circuit) and other electronic components to a glass substrate, the IC was mounted on a glass substrate (COG: Chip on Glass), and other electronic components were mounted on a flexible printed circuit board (FPC). : Flexible Printed Circuits). [0004] For example, if Figure 6 Like the illustrated liquid crystal device, SMD (Surface Mount Device) 101 such as a capacitor is mounted on FPC 102 , and IC 103 is mounted on glass substrate 104 . In addition, the FPC 102 and the glass substrate 104 ...
