The product description
A, product performance and features:
Silver copper clad powder is produced by our company introducing advanced foreign technology, electroless plating, choose German molding and surface treatment equipment, environmental chemical plating process, on the surface of ultrafine copper powder to form different thickness of silver plating; Has good oxidation resistance, good electrical conductivity, low resistivity, high dispersivity and high stability of a high conductive material, is the ideal substitute copper silver cost-effective conductive powder.
The powder volume resistivity is less than 1.8 x 10-3 Ω · cm, with the powder packing made of conductive coating, high conductivity (weight ratio of conductive fillers and resin for 75:25, volume resistivity of 4.5 x 10-3 Ω · cm), strong ability to resist the migration (nearly 100 times higher than that of ordinary silver conductive paint) and conductive stability (through 60 ℃ relative humidity 100% hot and humid test 1000 hours, volume resistivity increased less than 20%).
Our company production of flake and spherical silver plated copper powder, its silver content is between 5% and 30%, the customer can be selected according to the own, can also be made to order.
Second, use:
Silver copper clad powder can be widely used in conductive adhesive, conductive coatings, polymer slurry, and various kinds of conductive, conducting electrostatic need of microelectronics technology, the conductive material such as metal surface treatment and other industrial, is a new type of conductive composite powders.
Widely used in electronics, electrical, communication, printing, aerospace, military industry and other industry area of conductive and electromagnetic shielding. Such as computers, mobile phones, integrated circuit, all kinds of electrical appliances, electronic medical equipment, electronic instruments and meters, etc., make the product is not subject to electromagnetic interference, at the same time reduce the electromagnetic radiation damage to human body, and the colloid, circuit boards, such as insulators conductive processing, make the object of the insulation has good conductive performance.
