Aluminum PCB Advantages –Heat Dissipation and Thermal Conductivity
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.
Thermal conductivity and contraction is the common nature of the substance, different CTE is different in thermal expansion. As its own characteristics, aluminum have unique advance than normal FR4, thermal conductivity can be 0.8~3.0 W/c.K.

FAQ:
Q1. How about your supply capacity?
A: Our supply capacity is around 2000sqm each day. where our 25 000
sqm factory space hosts R&D, marketing, logistics and
procurement operations.
Q2. Is it OK to print my logo on product?
A: Yes. Please inform us formally before our production and confirm
the design firstly based on our sample.
Q3: What about the transportation and delivery date?
A: Normally,we use international express(such as,Fedex,DHL,TNT) to
deliver samples and small volume orders. For large mass order, we
can arrange shipping by sea.
