Metal Core PCB Manufacturing
Metal Core PCB, also called Metal Core Printed Circuit Board, MCPCB or thermal PCB, is circuit board that use metal material as the heat spreader portion of PCBs.
The use of base metals in the Metal Core Printed Circuit Board in stand of FR4 or CEM3 can dissipate heat away from critical board components and to less crucial areas such as metallic core or the metal heatsink backing.
In general, metal core PCB can be divided into aluminum PCB (aluminum core PCB), copper PCB (copper base PCB) and Iron PCB (Iron base PCB). The most common is an aluminum core Printed Circuit Board.
Aluminum Base PCB-Metal Core PCB-LED PCB
Metal Core Printed Circuit Board are widely used in following application:
Street safety applications: streetlights, lighting, etc.
LED lighting applications
System automotive LED applications
Power converters: telecom, industrial, high voltage regulator, power supplies
Hybrid/electric motor control applications
We as Metal Core PCB Manufacturer, we very deep understanding of the advantages of Metal Core Printed Circuit Board are great heat management during assembly of Printed Circuit Board, Metal core PCBs transfer heat 8 to 9 times faster than FR4 PCBs Better cooling.
