Metal Core PCB

Metal Core PCB, MCPCB Manufacturing Service

Overview of Metal Core PCB


Metal Core PCB, The printed circuit boards good thermal management solutions.


Metal core PCB (MCPCB), also known as heat sensitive PCB, insulated metal substrates (IMS PCB), Metal PCB, Metal Base PCB, Metal Backed PCB, Metal Clad PCB, etc., are designed to provide good thermal management, using metal substrates as circuit boards for radiator parts of circuit boards. These metal materials have high thermal conductivity. Aluminum is the most economical choice because it has good heat conduction and heat dissipation capacity and is cheaper than copper and steel. However, in order to adapt to different use scenarios, people choose different materials. Base metals in MCPCB are used as substitutes for FR4 or CEM3 boards. They radiate heat from key panel components to less important areas, such as metal radiator backings or metal cores. With the latest development of high power LED, the demand for MCPCB has exploded.


MCPCB is mostly single-sided IMS, metal core PCB manufacturer can also produce double-sided MCPCB, sometimes multi-layer IMS PCB and metal core PCB Prototype according to need. They have very advanced and perfect metal core PCB manufacturing process. Whichever MCPCB is chosen, the heat dissipation capability should be taken into account when choosing the thickness of base material and copper. The thermal conductivity is expressed in W/mK. The value of standard aluminium sheet is 1.0 W/mK, but other options may be 2.0, 3.0 or even 5.0 W/mK.


Most MCPCB surface treatments use HASL LF. Without fine spacing elements and BGA, HASL LF may be the most suitable finish for power LED components. However, nothing prevents us from proposing all other surface treatments; OSP, ENIG, Chem Tin or Silver for IMS applications.



Metal Core PCB for LEDs


Thermal Management PCBs are necessary for high power LED applications due to the amount of heat that LEDs generate. The bare board is the real estate that sustains electronic components such as LEDs. PCBs containing a metal core dissipate heat in LED applications. Furthermore, the MCPCB provides a much lower thermal resistance for light emitting diode applications.


The LED on the metal core printed circuit board (MCPCB) is designed to provide high power output in compact packaging. Each LED package contains an LED welded to MCPCB. These LEDs are very suitable for OEM or custom applications; therefore, they should not be used for home lighting.



Metal Core PCB Design Specifications


Metal Core PCB designers always focus on price and manufacturability. However, you can rest assured that we have experienced engineers who have been engaged in DFM inspection for many years, and provide you with suggestions for choosing the best materials.


Metal Core PCB, MCPCB produce by JHYPCB



Detailed Introduction of Metal Core PCB


Conventional PCB use FR4 epoxy glass-based material on both sides of a board. However, with the growing popularity of light-emitting diode or LED technology, metal core printed circuit board or MCPCB are being deployed to deal with the increased heat LEDs generate.

Today, metal core PCB are finding greater numbers of applications in the automobile industry, traffic light signal technology, in commercial buildings, shopping malls, and even inside homes.

MCPCB use either an aluminum or copper core with the bottom side of the board serving as the heat sink. MCPCB are also used to dissipate heat in intense power-generating analog circuitry.

Metal core PCB are connected through mounting holes and screws through a box build's chassis. In this arrangement, heat is not only dissipated through the metal core, but it is also transmitted to the chassis. Hence, an LED or analog device-populated board has a considerably larger surface finish for the purpose of dissipating that heat.

But here's a word of caution about using MCPCB – actually two things to be cautious about.


  • One, you need to know that making an MCPCB is complex and complicated because a metal layer is laminated with FR4, a glass-base material. Therefore, the chemistry for lamination is different during board fabrication. There is a fair possibility that there would be voids underneath the lamination, if it is not bonded properly.


  • Two, a fixture to dissipate the heat from the metal core needs to be carefully defined and designed. Both these concerns demand experience.

How Do Metal Core Circuit Boards Differ From FR4 Boards?


How Do Metal Core Circuit Boards Differ From FR4 Boards


One important difference to understand between standard PCB and MCPCB is how the materials work together to produce the desired result. In a typical LED MCPCB, there is a single circuitry layer of copper foil which is bonded to a layer of thermally conductive dielectric material, which is itself bonded to a thicker layer of metal – typically either Aluminum 5052, Aluminum 6061, or Copper C1100.

The dielectric material`s thermal conductivity is measured in Watts per meter, Kelvin (W/mK.) A 2.0W rating is fairly common; such material is approximately 6x-7x as thermally conductive as FR4. Best practice is to keep the dielectric layer as thin as possible. Doing so creates the shortest possible path from the heat source to the metal backing plate which is many times more thermally conductive than the dielectric material. Most of the materials come in a very limited range of thicknesses anyway, usually between .003" and .006". You won`t have all that much opportunity to specify something thicker that could diminish the effectiveness of the material at performing its thermal transfer function.

The metal backing plate used on the bottom side is the thickest element in the structure. It is available in several different thicknesses but it is best to use one of the three most common (1.0mm, 1.5mm, and 3.2mm) because they are the easiest to purchase without delays. The metal layer adds rigidity, keeps the circuit flat, and adds enough thickness so that the MCPCB can use the same mounting hardware that would be used for any other standard thickness circuit board. The metal plate side of the board does not receive any surface finish or soldermask.


Metal Core PCB Vs. Fr4 PCB Comparison

Metal Core PCB Vs. FR4 PCB Comparison


  • Conductivity: FR4 has low thermal conductivity, typically around 0.3W, while MCPCB has higher thermal conductivity, ranging from 1.0W-4.0W, most commonly around 2.0W.

  • Plated Through Holes: FR4 PCB typically uses plated through holes. Through hole components possible if required. In MCPCB, plated through holes are not available for 1-layer PCB. All components are surface-mounted.

  • Thermal Relief: Thermal relief in FR4 PCB typically involves vias for heat transfer. Longer drill cycle, adds many processes. MCPCB materials provide their own thermal relief. Via drilling, deposition, and plating processes are eliminated.

  • Solder Mask: FR4 PCB solder mask is typically dark colors (green, red, blue, black.) Usually applied top and bottom. MCPCB solder mask are almost exclusively white for LED boards. Applied to top only.

  • Thickness: FR4 PCB has a wide range of thicknesses available using various material combinations and layer counts. MCPCB thickness variation is limited by available backing plate thicknesses and dielectric sheet thicknesses.

  • Machining Process: FR4 PCB uses standard machining practices (drilling, routing, v-scoring, countersink, counterbore) while MCPCB uses the same machining as FR4, except that v-score must use diamond coated saw blades for the added strain from cutting into metal.

Metal Core PCB means the core (base) material for PCB is the metal, not the normal FR4/CEM1-3, etc. and currently the most common metal used for MCPCB manufacturer are Aluminum, Copper and steel alloy. Aluminum has good heat transferring and dissipation ability, but yet relatively cheaper; copper has even better performance but relatively more expensive, and steel can be divided into normal steel and stainless steel. It more rigid than both aluminum and copper, but thermal conductivity is lower than them too. People will choose their own base/core material according to their different application.

Benefits of Metal Core PCB Fabrication


Metal Core PCB Fabrication presents a host of beneficial features for a variety of applications. A lower thermal resistance can be achieved as a result of MCPCB's which incorporate a dielectric polymer layer together with a high thermal conductivity level.
Metal Core PCB Fabrication produces a product that transfers heat up to nine times more rapidly than a typical FR4 PCB. The laminates in MCPCB's dissipate heat which ensures that components which generate heat will remain cooler. This leads to a longer operating life as well as maximized performance for such components.
