3W/MK Aluminum Core PCB | Metal Core Circuit Board
(PCB's are custom-made products, the picture and parameters shown are just for reference)

the most common MCPCB construction consists of the following 3 layers:
1) A metal substrate, typically aluminum. In some applications, a copper substrate is more
Appropriate due to its high thermal conductivity than aluminum (401W/MK versus 237 W/MK)
but more expensive.

2) Epoxy dielectric layer. this is the most important layer in the MCPCB construction as it
Affects the thermal performance, electrical breakdown strength, and, in some cases, the
Solder joint performance of the MCPCB system. the typical thermal conductivity of the
Dielectric layer on a MCPCB is 1W/MK. A higher value is better for good thermal performance.
A thinner dielectric layer is better for thermal performance as well but can negatively impact
the ability of the MCPCB to withstand a high potential test to meet minimum electrical safety
Standards as required in certain lighting markets. the typical dielectric thickness layer is 100m.

3) Top copper layer. A thicker copper layer improves heat spreading into the PCB but may
Pose challenges for PCB manufacturers when fabricating narrow traces or spaces. A copper
Thickness of 1oz (35m) or 2oz (70m) is common.
