Types of Metal Core PCBs
There are four basic types of PCBs based on the location of the metal core and the trace layers. They include:
(1) Single-layer MPCB: A PCB with a single trace layer on one side.
(2) Double layer MPCB: PCB with two trace layers on the same side.
(3) Double-sided MPCB: These PCBs have two trace layers on each side.
(4) Multilayer MPCB: These PCBs have more than two layers per board.
Copper metal core PCB Benefits
The following advantages of metal core PCB make it ideal for different industrial applications:
(1) High thermal conductivity: Standard PCBs with FR4 and CEM3 have weak interlayer insulation and low thermal conductivity. Without proper cooling, internal temperatures may increase and affect internal components. A metal PCB made of aluminum has excellent thermal conductivity and helps keep internal components safe.
(2) Good dimensional stability: Compared with FR4 or CEM3 PCB, metal core PCB exhibits good dimensional stability. When the aluminum PCB is heated to a temperature of 30 degrees Celsius to 140~150 degrees Celsius, its size will expand between 2.5-3%.
(3) High thermal expansion: Coefficient of thermal expansion (CTE) is a term used to describe the expansion or contraction of a substance at temperature. Aluminum and copper have higher CTE than common FR4 and thermal conductivity of 0.8~3.0 W/cK
Copper metal core PCB Application
(1) LED lights: spotlights, high current PCBs, high current LEDs, street safety applications and all applications that use LEDs.
(2) Automotive: power conditioners, ignition tools, swap converters, variable optical systems, and electric motors for electric and hybrid vehicles.
(3) Power equipment: DC-DC converters, voltage regulators, high-density power conversion and switching regulators.
(4) Audio equipment: balanced, input and output, audio, power and pre-shielded amplifiers.
(5) Other electronic equipment: IC arrays, semiconductor heat shields, IC carrier chips, solar cell substrates, radiators and semiconductor refrigeration equipment.
(6) Household appliances: flat panel displays, motor controls,
(7) lOA equipment: large electronic display substrates, thermal print heads and printer drivers.
