Specification of Pre-insulated Copper Foil:

Copper foil tape can be divided into single and double conductive copper foil:

Single conductive copper foil tape refers to one side having an overlying non-conductive adhesive surface, and bare on the other side, so it can conduct electricity; so it is said that it is single-sided conductive copper foil

Double-sided conductive copper foil refers to copper foil that also has an adhesive coating, but this adhesive coating is also conductive, so it is called double-sided conductive copper foil.

1. Standard: Regard of different insulated coating material, the thermal endurance class are B, F, H in according to RoHS-2002/95/EC

2. Delivery State: With 100 and 200m copper foil round on the inner diameter of 76mm coil core

3. Storage Condition: No more than 6 months, under the dry and cool environment condition about 20℃

4.Tecnical Properties：

Available on pads and spool.

Performance of Copper Foil:

One side is copper, other side has insulating paper; In the middle is an imported pressure-sensitibe acrylic adhesive. Copper foil had strong adhesion and elongation, It is mainly due to copper foil’s excellent electrical properties that during processing it can have a good conductive effect; Secondly we use adhesive coated nickel to shield electromagnetic interference on the surface of copper foil.

Advantages of Pre-insulated Copper Foil:

- Copper foil purity is higher than 99.95%

- The function is to eliminate electromagnetic interference(EMI)

- Electrostatic charge will be grounded, strongly bonded, good conductive propertied.

- Reduces the necessary cross section of copper because of optimal shape in comparison to round wires

- Ease of getting admittance for a winding construction due to the optimal safety

- More reliable due to reduction of vibration, better thermal conductivity 

- Prevents danger of short circuit between primary and secondary windings
