Common sense of emi shielding conductive foil tape

xinst3月 20, 2020

Shielding material series EMI shielding conductive copper foil tape is an essential accessory for the electronics industry. Main applications are transformers, mobile phones, computers, and electronic products.


EMI shielding conductive copper foil tape is divided into single-sided lamination and double-sided lamination. Single-sided coated copper foil tape is divided into single-conducted copper foil tape and double-conducted copper foil tape. Single-conducted copper foil tape means that the coated side is non-conductive, and only the other side of copper is conductive, so it is called single-conducted or single-sided conductive ; Double-conducting copper foil tape means that the rubber-coated side is conductive, and the copper on the other side is also conductive, so it is called double-conducting, that is, double-sided conductive. There are also double-sided coated copper foil tapes that are used to process more expensive composite materials with other materials. The double-sided coated copper foil is also divided into conductive and non-conductive. The customer can according to their own needs for conductive Come to choose.


The purity is higher than 99.95%. Its function is to eliminate electromagnetic interference (EMI), isolate electromagnetic waves from harm to the human body, and avoid the need for voltage and current to affect functions. In addition, it has a good effect on static discharge after grounding. Strong adhesion, good electrical conductivity, can be cut into various specifications according to customer requirements.


This product is used for electromagnetic radiation interference, has better shielding effect, and has a good performance for grounded electrostatic discharge. At the same time, this product is also used for soldering purposes. Inspection parameters:
