Advantage of Metal core PCB
Some LEDs dissipate between 2-5W of heat and failures occur when the heat from a LED is not properly removed; a LED's light output is reduced as well as degradation when the heat remains stagnant in the LED package. The purpose of a MCPCB is to efficiently remove the heat from all topical IC's (not just LEDs). The aluminum base and thermally conductive dielectric layer act as bridges between the IC's and heat sink. One single heat sink is mounted directly to the aluminum base eliminating the need for multiple heat sinks on top of the surface mounted components.
2. thermal expansion
Thermal expansion and contraction is the common nature of the substance, different CTE is different in thermal expansion. As its own characterics, aluminum and copper have unique advance than normal FR4, thermal conductivity can be 0.8~3.0 W/c.K.
3. dimensional stability
It is clear that the size of the metal-based printed circuit board more stable than insulating materials. The size change of 2.5 - 3.0% when aluminum core PCB and aluminum sandwich panels was heated from 30 ℃ to 140 - 150 ℃.
4. Less expensive.
Aluminum is indigenous to a variety of climates, so it's easy to mine and refine. That makes it significantly less expensive to mine and refine than other metals. By extension, the manufacturing costs associated with products using aluminum core PCBs are also less expensive. Aluminum core PCBs are also a less expensive alternative to heat sinks.
5. Friendly to the environment.
Aluminum is a non-toxic, recyclable metal. From the manufacturer through to the end consumer, using aluminum in PCBs contributes to a healthy planet.
6. Very durable.
Aluminum is stronger and more durable than base materials like ceramic and fiberglass. It is very sturdy, and reduces accidental breakages that can occur throughout the manufacturing process, and during handling and everyday use.
Considering its durability, aluminum is very lightweight. It adds strength and resilience to PCBs without adding additional weight.
