Aluminum PCB / Metal Core PCB / MCPCB

MCPCB, Metal Core PCB, thermal PCB – No matter which name you prefer, they are all the boards taking a base metal material as the heat spreader portion of the circuit board. Base metals in the MCPCB are used as an alternative to FR4 or CEM3 boards for the ability to dissipate heat away from critical board components and to less crucial areas such as the metal heatsink backing or metallic core.

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 - 6 oz.



HDI is for High Density Interconnect. HDI any-layer printed circuit boards are the next technological enhancement of HDI PCBs that all the electrical connections between the individual layers consist of laser-drilled microvias. The main advantage of this technology is that all the layers can be freely interconnected. To produce these circuit boards, Seasons Electronics uses laser-drilled microvias electroplated with copper.


Special technologies :

1. Edge plating for shielding and ground connection

2. Minimum track width and spacing in mass production around 40μm

3. Stacked microvias (plated copper or filled with conductive paste)

4. Cavities, countersunk holes or depth milling

5. Solder resist in black, blue, green, etc.

6. Low-halogen material in standard and high Tg range

7. Low-DK Material for Mobile Devices

8. All recognized printed circuit board industry surfaces available
