Aluminum PCB Single Sided Metal Core PCB With 1W / MK for LED Lighting

1.1 General description
This is a type of Aluminum PCB for the application of Led Lighting. It's a single layer MCPCB board at 1.6 mm thick with 1 W/MK thermal conductivity. The aluminum plate is from ITEQ, Solder mask and silkscreen from Taiyo. It's fabricated per IPC 6012 Class 2 using supplied Gerber data. 25 boards are packed for shipment.

1.2 Layer up
The most common MCPCB construction consists of the following 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 100μm.

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 (35μm) or 2oz (70μm) is common.
