Thermal Pad Metal core PCBs

As a metal core PCB manufacturer
Andwin have been used in LED and
Power supply industries for more than 10 years!

Andwin provide high quality thermal pad MCPCB for customer, email us now for you PCB quote, email is : mcpcb@andwinmcpcb.com


What is thermal pad MCPCB?

LEDs Chip Thermal Pads solder direct to the Aluminum or Copper substrate directly,
No dielectric between LEDs heat out pads and the Metal core. Means,thermal resistance is very small and thermal conductivity could be 235 W/m.k to 395
W/m.k.

It is much better than regular MCPCB(1.0 w/m.k)

Stack up of Thermal pad MCPCB

Also, if you LED are suit for direct thermal MCPCB technology,
We could provide 175 W/m.k – 385W/m.k thermal conductivity.
