PCB Solutions is a solid source for an Aluminum Printed Circuit Board.

For high-powered LEDs most customers use an aluminum printed circuit board; for low-power LEDs standard FR4 PCBs are available as well. Our PCB fabrication specifications and build most types of metal based Printed Circuit Boards.

Aluminum Based PCBs are a unique metal-based copper clad laminate. These types of Printed Circuit Boards have good thermal conductivity, electrical insulation and very solid machining performance. These types of are typically fabricated with a metal base consisting of aluminum (most common) but can also be produced with copper.

Aluminum Printed Circuit Boards typically contain copper foil, thermal insulating layer and metal substrate, its structure divide into three layers:

1. Circuit layer: the equivalent of an ordinary PCB- copper thickness from 1oz to 10oz.
2. Insulation layer: Insulation is a layer of thermal insulating material with low thermal resistance. Thickness: 0.003 “to 0.006” inch is the aluminum PCB core technology.
3. Base Layer: a metal substrate, usually aluminum or copper.
