Next, the background technology to the invention of the 67th scheme~the 72nd scheme describes.
As the electronic devices and components that adopt the anisotropic conductive material band and the method for attachment between circuit card and the circuit card normally, clamping is as the anisotropic conductive material of the lining cement of film like between electrode of opposite, carries out being connected between electronic devices and components and circuit card and the circuit card by heating.In the lining cement of film like, be mixed with conducting particles in order to make mutual conducting between electrode.As resin, can adopt compound class, the ray hardening resin (reference example such as Japanese kokai publication sho 55-104007 communique) of thermoplastic base resin, thermosetting resin or thermoplastic base resin and thermosetting resin.
In addition, known also have to use do not contained conducting particles, only the circuit connecting method (reference example such as Japanese kokai publication sho 60-262430 communique) of the anisotropic conductive material that is made of resin.
In the representative resin, known have, and as type thermoplastic resin, polystyrene resin class, Polyester resin class arranged, and in addition, as the thermosetting resin class, epoxy resin, silicone resin class, third rare resene arranged.In order to connect, type thermoplastic resin and thermosetting resin class all must be carried out thermo-compressed.For type thermoplastic resin, be for make resin flows obtain with by the closing force of sticky object, and for the thermosetting resin class, be in order further to carry out the hardening of resin reaction.In recent years, from the bonded assembly reliability, the compound class and the thermosetting resin class of thermoplastic base resin and thermosetting resin have become main flow.In addition, can carry out the bonded assembly ray hardening resin at low temperatures also brings into use in industry.
In addition, in recent years,, require the low temperatureization of the connection temperature of anisotropic conductive material when connecting in order to prevent to be connected the warpage and the stretching of thing.In addition, be accompanied by the expansion of the needs of the expansion of connection purposes of anisotropic conductive material and liquid crystal display, PDP screen, EL screen, bare chip installation etc., the requirement of the shortening of the production pitch time when connecting is more and more stronger.
In addition, be accompanied by the connection needs of anisotropic conductive material and the expansion of purposes, not only require the short time to connect, also require to increase productivity.Along with the expansion of the needs of liquid crystal display, PDP screen, EL screen, bare chip installation etc., the use amount of anisotropic conductive material is also in continuous increase.In addition, along with the expansion of the needs of the big flat screens of picture such as the big picture of liquid crystal display and PDP screen, anisotropic conductive material employed use amount in 1 screen also increases.In the past, anisotropic conductive material was to be that the reel of the lining cement of multilaminate coiled film shape on the core of circle is supplied with in the cross section, and the replacing time of spool has hindered productive raising.
On the other hand, be accompanied by the narrow limitization of liquid crystal display, the change in a narrow margin of anisotropic conductive material constantly makes progress, be wound on in the past identical circular core on reel volume can take place collapses, the qualification rate in the Fabrication procedure is reduced.
The invention of the 67th scheme~the 72nd scheme, in view of there being above-mentioned shortcoming, its purpose is to provide a kind of replacing time gap that can prolong spool, can not collapse and not cause the operation reduction because of volume takes place, help to increase productivity the anisotropic conductive material band.
