Compression bonding device

Abstract

A compression bonding device capable of packaging electric components on both sides of a substrate is provided. A compression bonding device includes first and second pressing rubbers. Electric components can be simultaneously packaged on the front face and the rear face of a substrate by sandwiching the substrate between the first and second pressing rubbers. The electric components are not subjected to a force for horizontally moving them because the first and second pressing rubbers are prevented from horizontal extension by a first dam member. Thus, the electric components are connected to the substrate without misalignment, thereby obtaining a highly reliable electric device.

1 . A compression bonding device comprising:
 first and second pressing rubbers configured so that an object to be pressed which is placed between the first and second pressing rubbers can be pressed by the first and second pressing rubbers; and   a dam member positioned higher than a surface level of the first pressing rubber is placed around the first pressing rubber,   wherein the second pressing rubber can be inserted into a space surrounded by the dam member.   
     
     
         2 . The compression bonding device according to  claim 1 , wherein the first pressing rubber is placed on a first pressing plate,
 wherein a first compression member, which is compressively deformable, is placed between the first pressing rubber and the first pressing plate, and   wherein the first dam member becomes higher than the surface level of the first pressing rubber at least when the first compression member is compressed.   
     
     
         3 . A compression bonding device comprising:
 first and third pressing rubbers configured so that an object to be pressed which is placed between the first and third pressing rubbers can be pressed by the first and third pressing rubbers; and   a dam member positioned higher than a surface level of each of the first and third pressing rubbers is placed around each of the first and third pressing rubbers.   
     
     
         4 . The compression bonding device according to  claim 3 , wherein the first pressing rubber is placed on a first pressing plate,
 wherein a first compression member, which is compressively deformable, is placed between the first pressing rubber and the first pressing plate, and   wherein the first dam member becomes higher than the surface level of the first pressing rubber at least when the first compression member is compressed.   
     
     
         5 . A compression bonding device comprising:
 fourth and fifth pressing rubbers configured so that an object to be pressed which is placed between the fourth and fifth pressing rubbers can be pressed by the fourth and fifth pressing rubbers,   a dam member surrounding the fourth and fifth pressing rubbers; and   the dam member is separable from the fourth and fifth pressing rubbers.   
     
     
         6 . The compression bonding device according to  claim 5 , wherein the dam member is tubular, and
 wherein the fourth and fifth pressing rubbers can be inserted into the tube of the dam member.
