Thermal conduct Al-Substrate CCL provides the advantages of high thermal conductivity, Excellent solder heat endurance, Excellent Breakdowm Voltage, reliability, Thermal Conductivity is about five~ ten times higher than the FR-4 pcb , PCB produced by the substrate can transfer heat , which is electrionic components generate , throughing the substrate structure rapid conduct to the back-end cooling base or other cooling modules. Al-Substrate CCL is a sandwich structure, which includes layers of conductor ,insulator and metal base.
In genaral, this insulator is made of epoxy resin and high thermal Conductivity filler. The products have been through a number of demanding for a long time environmental testing, access to international certification. Huazheng new material has a strong R&D strength, which continued to develop avariety of high Thermal Conductivity pcb products. Thermal conductivity 1.0～3.0 W/ M·K，It can fit the demand of high end and mid-range products，with high cost performance. All products pass RoHS standard, have good property andmeet low-carbon environmental trend.

- Dielectric Breakdown Voltage
HA50 product has excellent dielectric Breakdown Voltage even after solder dippling
Dielectric Breakdown Voltage test value refers to the value of Al-Substrate CCL， and not
Al-Substrate PCB test value. Because of design and the air facor, the Al-Substrate PCB test value will
be lower than the value of substrate.
- Peeling Strength
HA50 product has excellent Peeling Strength even after solder dippling
