Metal Core PCB


Hemeixinpcb is a PCB technology that makes it possible to conduct heat out of the LED and into the atmosphere in a faster and more efficient manner. While the primary focus of Hemeixinpcb is the rapidly evolving LED market, there are other applications for which Hemeixinpcb is an ideal candidate.

The thermal conductivity assisted by the aluminium core in the circuit boards makes higher packing densities, longer operating times, and improved security against failure possible, such as for LED technology and for high power transistors.

The Hemeixinpcb promise is to reduce LED junction temperature allowing users to increase LED life, increase reliability, increase brightness, increase lumens per LED and reduce cost per lumens and that is a promise Hemeixinpcb definitely delivers on.

What is an IMS PCB?

IMS = Insulated Metal Substrate, It also called metal core pcb. A metal core printed circuit board (MCPCB) also known as thermal PCB, incorporates a metal material as its base as opposed to the traditional FR4, for the heat spreader fragment of the board. Heat builds up due to some electronic components during the operation of the board. The purpose of the metal is to divert this heat away from critical board components and towards less crucial areas such as the metal heatsink backing or metallic core. Hence, these PCBs are apt for thermal management.

Copper circuitry bonded onto an electrically insulated thermal dielectric layer, that is bonded to a metallic substrate.

  • The insulating thermal dielectric is a special material, with good thermal conductivity; normally it is 8 to 10 times more thermally conductive than FR4.
  • The dielectric is normally is made using a filling material that normally used aluminium oxide, aluminium nitride, boron nitride, magnesium oxide or silicon oxide.
  • An aluminium metal base is perhaps the most common metallic base. It is suitable for drilling, punching and cutting.
  • In most cases and IMS board reduced the need for heat sinks.

Aluminum pcb Base metal

  • Consider the application to choose suitable metal base
  1.  For normal lighting application, can choose 1K (1100) and 3K (3003) serial Aluminium ;
  2.  For Power application, can choose 5K (5052) serial Aluminium;
  3.  For Rectification application (shaking environment), can choose 6K (6061) serial Aluminium ;
  4.  Postfix name “H” means; Work hardening state to increase strength; “T” means after heat treatment; the first digital after “H” &”T” means degree; see next slide.

At Hemeixin you can get aluminium core PCBs with a thermal conductivity of 1.0 W/mK to 8 W/mK. The aluminium core helps to distribute the selective heat of heat-intensive components and to make the heat development on the printed circuit board more homogenous. The rule of thumb for many high-power LEDs is: A 10° C lower junction temperature increases the lifetime by 10.000h.

For one-sided metal core PCBs, a heat sink and/or fan (active cooling) can be mounted directly on the aluminum (passive cooling).
