1. Introduction of the Electromagnetic shielding Copper foil
Pure Copper foil has a low surface oxygen characteristics, can be attached with a variety of different substrates, such as metal, insulating materials, etc., have a wide range of temperature use.
Mainly used in electromagnetic shielding and anti-static, the conductive copper foil placed on the substrate surface, combined with metal substrate, with excellent continuity, and provide the effect of electromagnetic shielding.
Pure copper foil can be divided into two categories: rolled copper foil (RA copper foil) and point copper foil (ED copper foil)
