Conductive glue (conductive glue) can be used to bond wires on circuit boards instead of soldering irons, and is generally found in IC packaging factories.
Conductive adhesive can connect a variety of conductive materials together to form an electrical path between the connected materials. In the electronics industry, conductive adhesive has become an essential new material.
There are many types of conductive adhesives. From the perspective of application, conductive adhesives can be divided into two categories: general conductive adhesives and special conductive adhesives. General conductive adhesives only have certain requirements for conductive properties and bonding strength of conductive adhesives. In addition to certain requirements for conductive properties and bonding strength, special conductive adhesives also have certain special requirements, such as high temperature resistance, ultra-low temperature resistance, and instantaneous resistance. Curing, anisotropy and transparency, etc.
Extended information:
Conductive adhesive is mainly composed of resin matrix, conductive particles, dispersing additives, auxiliaries, etc. The matrix mainly includes epoxy resin, acrylic resin, polyurethane, etc.
Although the structure of highly **** yoke type polymer itself is also conductive, such as macromolecule pyridine structure, etc., it can conduct electricity through electrons or ions. However, the conductivity of this type of conductive glue can only reach the level of semiconductors at best.
Most of the conductive adhesives used on the market are filler types. The conductive fillers can be powders of gold, silver, copper, aluminum, zinc, iron, nickel, graphite and some conductive compounds.
