Aluminum PCB

Aluminum PCB , also,it is called Aluminium PCB,metal core PCB,mcpcb, IMS(Insulated metal substracte).

Aluminum PCB have 3 parts:
1.Circuit Layer (Copper Layer)
This is printed circuit copper foil layer, From 1.0 oz up to 8 oz (35um-280um). Min.Trace/space 5/5mil(0.127/0.127mm)

2.Dielectric Layer(Insulated Layer)
There are very good price and delivery time if the raw material made in China and Taiwan, we also,have many customer who choose Bergquist Thermal-Clad and Larid Tlam material,strict meet customer’s Requirement to manufacture the ALPCB.

3.Substrate Layer(Metal layer)
There are 4 types Aluminum, 1001, 3001, 5052, 6063. If no requirement of this from,we used 5052 for High thermal conductivity (2.0 W/m.k or more) , AL1001,AL3001 for 1.0 w/m.k to 1.5 W/m.k aluminum-stack-up

Aluminum Clad PCBs

Available as 1 layer Non-Plated Through Hole (single sided), And 2+ layer Plated through Hole. Ideal application for LED lighting, power supply solutions. Aluminium Clad Benefits Include:

  • Lower operating temperature.
  • Reduce printed circuit board size.
  • Increase power density.
  • Extend the life of dies.
  • Reduce the number of interconnects.
  • Improve product thermal and mechanical performance.
  • Combine power and control.
  • Improve product durability.
  • Enable better use of surface mount technology.
  • Expedite heat sinks and other mounting hardware.
  • Replace fragile ceramic substrates with greater mechanical durability

About Price:

Price is based on the requirement of LED PCB

1. PCB thickness: 0.6 – 3.0mm, always thickness more ,price higher

2. Thermal conductivity: 1.0 – 10 W/m.k , thermal conductivity higher, price higher

3. Material factory: Bergquist, Laird ETC, made in US factory that is more expensive than China.
