Flexible Copper Clad Laminate CCL Sheet Film
Flexible Copper clad laminates has good heat dissipation property, as the copper has excellent thermal conductivity. It effectively solves the problem of high temperature caused by long time operation of electronic products, so it's the perfect choice for a printed circuit board. Choosing soft Polyimide Film and pet film as substrate film, then cover the copper to the surface of the polyimide film or Pet Material Film, makes the Copper clad laminate has both electrical and thermal conductivity and flexibility. And copper has excellent properties for absorbing electromagnetic waves, so the Flexible CCL is also used for EMI Shielding, RF Shielding for Aerospace or military products.
For our Dajia New Materials, the copper come in two types: ED COPPER AND RA COPPER. Both copper is pure copper, oxygen free copper. Need special emphasis, we offer two sides copper clad laminates and single side copper clad laminates. And for the substrate film, there are pet film and polyimide for your choose.
Polyimide main features:
1:High temperature resistance: high temperature of more than 400℃, long-term use temperature range -200 ~ 300℃, no obvious melting point. 2. High insulation performance: 103 Hz dielectric constant 4.0, dielectric loss is only 0.004 ~ 0.007, belongs to F to H class insulation material.
3.Flame retardant.
1.can be used in the temperature range of 120 ° C for a long time, can withstand -70 ° C low temperature
2.high and low temperature have little impact on its mechanical properties
The thickness of each layer of copper clad polyimide/pet film laminates is according to your request.
