Description
Shenzhen Hengda specialized in Aluminum Printed Circuit Boards (also called Metal base PCBs) for over 10 years. Although originally envisioned for use in the power-supply industry these substrates are now most widely used in High Brightness LED products. There are many names for these products; Aluminum clad, aluminum base, Metal core(MCPCB), Insulated Metal Substrate(IMS or IMPCB), Thermally conductive PCBs, etc… but they all mean the same thing. A thin layer of thermally conductive but electrically insulating dielectric is laminated between a metal base and a copper foil. The copper foil is etched into the desired circuit pattern and the metal base draws heat away from this circuit through the thin dielectric.
Using a metal core PCB in these LED products and applications help to greatly reduce the heat emitted.
Other applications that are ideal for MCPCB integration are solar panels and motion control applications. We can also combine metal core with our HDI PCB technology.
Metal Core PCB Materials and Thickness
The metal core of the thermal PCB can be aluminum (aluminum core PCB), copper (copper core PCB or a heavy copper PCB) or a mixture of special alloys. The most common is an aluminum core PCB.
The thickness of metal cores in PCB base plates is typically 30 mil - 125 mil, but thicker and thinner plates are possible.MCPCB copper foil thickness can be 1 - 10 oz.
Advantages of MCPCB
MCPCBs can be advantageous to use for their ability to integrate a dielectric polymer layer with a high thermal conductivity for a lower thermal resistance.
Metal core PCBs transfer heat 8 to 9 times faster than FR4 PCBs. MCPCB laminates dissipate heat, keeping heat generating components cooler which results in increased performance and life.
Products with Aluminum based pcb
Applications that generate a large amount of heat often cannot be adequately cooled using just traditional fans. Conductive cooling through metal core PCBs are an ideal production option.
MCPCBs are most widely found in LED technologies, as they reduce the number of LEDs required to produce a specific illumination. Light emitting diodes release a great amount of heat in applications such as
- Automotive: Head lights, Tail light assemblies, Running side markers, Dash board, interior lighting.
- Military: Head lights, Running lights, Spot lights, Signal beacons, High power flash lights, Power converters, Power supplies, Power transmission systems, Ignition systems, Power distribution products.
- Aerospace: Aircraft landing lights, Running lights, Cabin mood lighting systems, Spot light and general lighting.
- Consumer: Street lighting, Traffic control lighting, Interior building lights, Landscape lighting, Camping gear.
- Medical: Operating room lighting, Surgical lighting tools, High power scanning technology, Power converters.

Testing Procedures
We perform multiple quality assurance procedures before shipping out any PCB board. These include:
- Visual Inspection
- Flying probe
- Bed of nails
- Impedance control
- Solder-ability detection
- Digital metallograghic microscope
- AOI (Automated Optical Inspection)
Quick turn lead times
For HDI PCB production, we can provid 7 to10 days turn around times. For multilayer PCBs, the fastestturnaround time depends on the number of layers and quantity.
