Application field of conductive adhesive
Conductive adhesives are used in microelectronics assembly, including the connection of fine wires to printed lines, plating plates, metal layers of ceramic adhesives, metal chassis, bonding wires to tube seats, bonding elements to flat faces across printed lines, bonding waveguide tuning, and hole repair.
Composition of conductive adhesive
The conductive adhesive is mainly composed of resin matrix, conductive particles, dispersing additives and auxiliaries. The matrix mainly includes epoxy resin, acrylic resin, polychloride ester and so on. Although the highly conjugated type of polymer structure itself also has electrical conductivity, such as macromolecular pyridine structure, can conduct electricity through electrons or ions, but the conductivity of this kind of conductive adhesive can only reach the degree of semiconductor, can not have low resistance like metal, difficult to play the role of conductive connection. The conductive adhesive used on the market is mostly filler type.
Conduction principle of conductive adhesive
Form a conductive path, so that the conductive adhesive has electrical conductivity, the stable contact between the particles in the adhesive layer is caused by the conductive adhesive curing or drying. Conductive adhesive before curing or drying, conductive particles are separated in the adhesive, there is no continuous contact with each other, so in the state of insulation. Conductive adhesive curing or drying, due to solvent volatilization and adhesive curing caused by the shrinkage of the adhesive volume, the conductive particles between each other is stable continuous state, thus showing electrical conductivity.
The removal method of double-sided tape
Scratch the beginning with a razor blade and peel off slowly with your hand. If the speed is too slow, a hair dryer can be used to heat slightly.

Know newsprint as a printing material
It has been more than two thousand years since the invention of paper, and this material has become an important printing material in printing production. There are many kinds of printing paper, mainly coated paper, offset paper, newsprint, special paper, bar code paper and so on. Among them, newsprint is also called white newspaper, mainly used in newspapers and books printing production. Here, we have A understanding of this paper material, as follows: newsprint with natural mechanical wood pulp, unblemished or semi-blemished sulfite wood pulp auxiliary copy, can be divided into A, B, C, D four grades (A, B grades can be applied to high-speed rotary offset printing
