Metal Core PCB:
Metal Core PCB Fabrication includes the design and production of
printed circuit boards (PCB\'s) with a metal core, intended for use
with LED-based Solid State Lighting and other applications where
heat dissipation is required.
Oneseine Company
Metal Core PCB means the core (base) material for PCB is the metal,
not the normal FR4/CEM**3, etc. and currently the most common metal
used for MCPCB manufacturer are Aluminum, Copper and steel alloy.
Aluminum has good heat transferring and dissipation ability, but
yet relatively cheaper; copper has even better performance but
relatively more expensive, and steel can be divided into normal
steel and stainless steel. It more rigid than both aluminum and
copper, but thermal conductivity is lower than them too. People
will choose their own base/core material according to their
different application.
Generally speaking, aluminum is the most economic option
considering thermal conductivity, rigidness, and cost. Therefore,
the base/core material of normal Metal Core PCB are made of
aluminum. In our company, if not special request, or notes, the
metal core refer will be aluminum, then MCPCB will means Aluminum
Core PCB. If you need Copper Core PCB, Steel Core PCB, or Stainless
steel core PCB, you should add special notes in drawing.
Sometimes people will use abbreviation MCPCB, instead of the full
name as Metal Core PCB, or Metal Core Printed Circuit Board. And
also used different word refers the core/base, so you will also see
different name of Metal Core PCB, such as Metal PCB, Metal
Base PCB, Metal Backed PCB, Metal Clad PCB and Metal Core Board and
so on.(oneseine.com)
MCPCBs are used instead of traditional FR4 or CEM3 PCBs because of
the ability to efficiently dissipate heat away from the components.
This is achieved by using a Thermally Conductive Dielectric
Layer.
The main difference between a FR4 board and MCPCB is the thermal
conductivity dielectric material in the MCPCB. This acts as a
thermal bridge between the IC components and metal backing plate.
Heat is conducted from the package through the metal core to an
additional heat sink. On the FR4 board the heat remains stagnant if
not transferred by a topical heatsink. According to Avagos white
paper (AV******5EN.pdf) a MCPCB with a 1W LED remained near an
ambient of *5C, while the same 1W LED on a FR4 board reached *2C
over ambient. LED PCB always be produced with Aluminum core, but
sometimes steel core PCB also be used.
Benefits of Metal Core PCB Fabrication
Metal Core PCB Fabrication presents a host of beneficial features
for a variety of applications. A lower thermal resistance can be
achieved as a result of MCPCB\'s which incorporate a dielectric
polymer layer together with a high thermal conductivity level.
Metal Core PCB Fabrication produces a product that transfers heat
up to nine times more rapidly than a typical FR4 PCB. The laminates
in MCPCB\'s dissipate heat which ensures that components which
generate heat will remain cooler. This leads to a longer operating
life as well as maximized performance for such components.
Applications of Metal Core PCB Fabrication
With the adoption of new technologies, there are many more
applications for Metal Core PCB Fabrication. This technology is
ideal for applications where components generate a large amount of
heat and have difficulty being cooled using conventional fans and
other cooling methods. In Solid State Lighting, MCPCB\'s help
achieve a higher level of illumination with fewer LED\'s required
to produce it.
Although LED-based Solid State Light technologies have countless
advantages, they inherently produce significant amounts of heat.
This makes Metal Core PCB Fabrication helpful for applications
like:
General Lighting
Automotive Systems
Power Converters (industrial, telecom, power supplies, and high
voltage regulators)
Photovoltaic
Street Safety (lighting, streetlights, etc.)
Back Light Applications
Aluminum PCB:
Aluminum PCB Advanced Circuits Specification
Among all Metal core PCBs (aka MCPCBs, known for their ability to
provide effective thermal dissipation for electronic products),
Aluminum PCBs is the most common type - the base material consists
of aluminum core with standard FR4. It features a thermal clad
layer that dissipates heat in a highly efficient manner, while
cooling components and increasing the overall performance of the
products. Currently, Aluminum Backed PCBs is regarded as the
solution to high power and tight tolerance applications.
Oneseine\'s been manufacturing aluminum PCBs for *0+ years. Our
full feature aluminum circuit boards making capabilities and Free
DFM Check allow you to get high-quality aluminum PCBs done within
budget. Our printed Aluminum PCBs are widely used for LED lighting,
power equipment and automotive systems.
