Metal Core PCB, MCPCB Manufacturing Service

Resume

Metal Core PCB uses 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 CEM-3 boards for the ability to dissipate heat away from critical board components and to less crucial areas such as the metal heat sink 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 aluminum core PCB is most common.

Metal Core PCB, MCPCB produce by JHYPCB

INTRODUCTION

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.

Material for Metal Core PCB


Material for Metal Core PCB


Metal Core PCB material including Aluminum Core PCB, Copper Base PCB, Iron base PCB.  Aluminum is popular in the market special in LED lights market because of Cost .

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.

1. Aluminum PCB

Aluminum PCB , also, it is called Aluminium PCB, metal core PCB, MCPCB, IMS(Insulated metal substracte).

Benefits of Metal Core PCB Fabrication


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.

Applications of Metal Core PCB Fabrication


Applications of Metal Core PCB Fabrication


With the adoption of new technologies, there are many more applications for Metal Core PCB Fabrication. This technology is ideal for applications where components generate a large amount of heat and have difficulty being cooled using conventional fans and other cooling methods. In Solid State Lighting, MCPCB's help achieve a higher level of illumination with fewer LED's required to produce it. 

Although LED-based Solid State Light technologies have countless advantages, they inherently produce significant amounts of heat. This makes Metal Core PCB Fabrication helpful for applications like: 

  • General Lighting
  • Automotive Systems
  • Power Converters (industrial, telecom, power supplies, and high voltage regulators)
  • Photovoltaic
  • Street Safety (lighting, streetlights, etc.)
  • Back Light Applications

Other applications that are ideal for MCPCB integration are solar panels and motion control applications. We can also combine metal core with our HDI PCB technology. We also offer other advanced circuit technology including flexible PCB rigid PCB, and rigid flex PCB.
