What Defines An MCPCB LED?

A PCB com núcleo de metal is a special type of circuit board that utilizes a metal-based substrate.

Usually conventional circuit boards employ Material FR-4 or CEM para o substrato.

The metal backing of an MCPCB consists a metal core, most often aluminium or copper metal.

Usually this board consists of a metal laminate, a layer of conductive copper and isolation layers.

A MCPCB LED is therefore a circuit configuration that includes a light emitting diode on a metal core PCB.

The use of MCPCBs for LED came about as a result of the high heat generation when using LEDs.



What Differentiates MCPCB From FR-4 PCB?

For efficient thermal dissipation, a metal core PCB uses metal backing as a substrate.



You employ FR-4 material in the construction of a circuit board due to its availability and impressive features.

You can compare the two materials on the following grounds:


A metal core PCB has a high stress threshold. You note that this circuit board can tolerate great amounts of shock compared to an FR-4 board.


When compared to FR-4 PCBs, metal core PCBs are more expensive to create and thus purchase. Because FR-4 can be produced in huge quantities at a low cost, such boards can be sold at a cheaper cost.

Procedimentos de Fabricação

Drilling through holes and coating them as thermal relief pathways are some of the operations involved in creating an FR-4 board.

You find no need for such processes on MCPCB boards as they are self-sufficient in heat elimination.


Metal core PCB has better conductivity than FR-4 PCB, reaching up to nine times greater than that of FR-4.

Alívio Térmico

Plated through-holes are essential when using FR-4 PCBs in high-temperature situations. You employ SMT mounting technology in MCPCBs, thus you have no alternative for PTHs.


Depending on the various layer sizes and counts, a FR-4 board can have varied thicknesses.

You determine the thickness of an MCPCB by establishing the thickness of the metal plate and the dielectric layer.



máscara de solda

When using an FR-4 circuit board, you can have solder masks on both the top and bottom surfaces. Additionally, you can provide these masks in a variety of colours, other than the customary green.

For a metal core PCB, solder mask application is on the top surface only. Furthermore, the accustomed colour for the mask is white.

Where Do You Use MCPCB LED?

The MCPCB LED is common in lighting applications that require a lot of heat dissipation. You find this is something that traditional boards like FR-4 can’t manage.

MCPCB LEDs are common in the following applications:

  • Illumination applications including street lights employ the metal core PCB LEDs.
  • The backlight feature in many electronic equipment such as laptops utilizes MCPCB LED.
  • Downlights, spot lights, navigation lights, tube lights, high bay lights, flood lights, and cove lights are examples of high-power LED applications.
  • MCPCB LEDs are used in some automotive applications, such as hybrid and electric motor control.

What Benefits Derive From Using MCPCB LED?

You appreciate your metal core PCB LED’s response in regard of thermal management. The following are some of the benefits of using an MCPCB LED:

  • The longevity of a metal core PCB LED, is undisputed. When compared to epoxy material, for example, metal PCBs offer a longer service life.
  • In a high-vibration application, you’ll notice that an MCPCB LED’s metal backing absorbs the majority of the vibrations.
  • You facilitate accelerated heat transfer when you utilize material with great conductivity such as MCPCB LED.
  • Metal Core PCB LED is subject to recycling efforts and without harmful chemical composition making them safe to our environment.
  • Using backing for your MCPCB LED, such as aluminum, helps you to make lighter gadgets.

When compared to ceramic materials, aluminum is a light material with excellent thermal dissipation properties.

  • You can combine an MCPCB LED with a dielectric made of a polymer with high thermal conductivity and low resistance.
  • It is possible to pattern the metal core of this board type for component isolation and regulation of thermal state.

What Metals Can You Fabricate MCPCB LED With?

Using a metal backing allows you to more efficiently disperse the huge heat generated by LED applications, preventing heat build-up.

Aluminum and copper metals enjoy common use as the metal core in MCPCB LED applications.

In an MCPCB LED, using aluminum for the metal core allows for excellent heat conduction and transfer.

Also, aluminum barely tips the scale allowing you to employ it in compact with weight limitations like LED light systems.

When constructing an MCPCB LED, you can provide an aluminium core with a thickness of 40 to 120 mils.

Copper metal is another viable alternative for metal core use in an MCPCB LED.

However, working with copper is exigent due to its weight and cost despite its impressive properties.

Aluminium alloys are also useful in reinforcing conduction and thermal expansion properties.

You can combine aluminum with chromium or magnesium to form an alloy that is highly workable.

Why Is Aluminium Used As A Metal Core For MCPCB LED?

For excellent thermal dissipation, an MCPCB LED uses a metal core backing as a substrate.

Aluminum and copper are two typical metals you can utilize as MCPCB LED metal cores.

The following characteristics of aluminum make it a preferred choice for many MCPCB LEDs as a metal backing:


Aluminium is a naturally occurring metal that can be found almost anywhere on the planet, making it readily available.

You thus find aluminium costs fairly cheaper than substitute metals making manufacture inexpensive.

Expansão térmica inferior

Thermal expansion is a material feature that causes it to expand in size when the temperature rises. Separation misalignment is common in instances of thermal build-up for metal core boards.

You experience reduced thermal manifestations at the behest of generated heat when employing aluminium.

When you use surface mount components on your MCPCB LED, thermal expansion can be a concern.

Ambiente amigável

Aluminium is environmentally friendly because it has no harmful components and is 100% recyclable. Furthermore, manufacture of aluminum is easy reducing the amount of energy required to deal with it.


When aluminium is under thermal influence, it barely expands in volume.

Expansion usually disrupts the material structure of a design and if not accommodated can be damaging.

A metal core PCB employing aluminium will exhibit insignificant change in shape and size under thermal influence.

Excess heat finds its way out preventing board damage through warping for instance.


Aluminum has amazing physical features such as hardness and toughness, yet it is also quite light.

You can therefore adequately employ it in MCPCB LED.


The physical strength and stability that aluminium metal as a core provides your MCPCB LED is astounding.

Aluminium has outstanding mechanical attribute that mitigates the shock performance of a metal core PCB LED.

Significant Heat Dissipation

Thermal stress occurs when a considerable amount of heat accumulates on your board, leading to damage.

Thermal conduction capability is minimal in materials like FR-4 and CEM 3, which you use as substrate in traditional PCBs.

Because of its high thermal conductivity capability, aluminum is capable of effectively dispersing enormous amounts of heat.

Using aluminum in your metal core PCB LED lessens the chance of a thermal-related pressure.

What Classifications Of Aluminium Core Can You Utilize in MCPCB LEDs?

There are three main types of aluminum core you can employ on your MCPCB LED.

You determine capable heat performance from these substrates despite their differing are of use:

Aluminum-backed MCPCB LEDs are divided into three categories:

  1. Universal Aluminium PCB: The dielectric layer in this case is epoxy and glass fiber prepreg.
  2. High Thermal-Conductive Aluminium PCB: Especially for MCPCB LEDs with huge thermal dissipations. The dielectric layer comprises epoxy resin, which has a high thermal conductivity.
  • High-frequency Aluminum PCB: Suitable for high-frequency applications employing resin glass fiber pre-preg as dielectric layer.

How Different Are Copper And Aluminium-based MCPCB LEDs?

aluminum based MCPCB LED

Aluminum based MCPCB LED

Use of copper or aluminium for a metal core PCB LED is prevalent. The distinctions between the two metals are highlighted in the following:

  • When compared to an aluminium-based MCPCB LED, copper-based MCPCB LEDs have higher thermal performance.
  • Copper weighs more than aluminum, making its use in the manufacture of a metal core PCB LED exigent.
  • Copper costs more to obtain than aluminum, and thus increases the overall manufacturing costs of the metal core PCB LEDs.
  • The susceptibility of copper to corrosion is discouraging and thus MCPCB LEDs employing such have a high tarnishing rate.

What Fabrication Techniques Can You Apply For MCPCB LED?

There are several manufacturing processes that you undertake when furnishing MCPOCB LED. Some common processes are as follows:

Gravura de cobre

While your MCPCB LED has a metal backing, electrical transfer requires a conductive layer.

You make this layer through pattering the metal foil of given weight in a desired design.

Printing Solder Masks

Because an MCPCB LED uses a thicker conductive layer film, printing the solder mask can be difficult. Using extremely thick copper develops a great disparity between the conductive and underlying layers. You may solve this difficulty by using the two-time printing approach to produce the solder mask.

Mechanical Fabrication

Drilling the MCPCB LED, molding, and scoring are all mechanical fabrication processes.

You should keep these procedures to a bare minimum because they degrade the board’s electrical performance.

How Do You Arrange Your MCPCB LED Layers?

A solder mask, conductive track, dielectric layer, and metal backing make up an MCPCB LED’s structure. The conductive layer usually employs a one to six ounce copper plate, with the metal backing acting as a heat sink.

You can stack an MCPCB LED in a variety of ways, as seen below:

Camada única

A metal base, a dielectric layer, a conductive track, and a solder mask make up a single layer MCPCB LED.

You join board populates to the trace which can weigh anywhere between one and six ounces per square feet.

Duas camadas

With the two layer MCPCB LED, you use two conducting layers in addition to the metal core.

You position the conductive layers above the metal core with the backing at the base.

Your metal backing can be aluminum, copper, or an iron alloy.

Plated through-holes are useful in creating connection between the layers for both signal and heat.

Dupla face

The conductive layers are on either side of the metal backing in this stack.

The double-sided design allows you to have components on both the external surfaces increasing throughput.

You can similarly employ PTH for electrical signal transfer or as heat conduits.

Furnishing NPTH is not far-fetched either as you can mount board features through them.

Dupla Camada

The design rules for a multilayer MCPCB LED are the same as for a multilayer FR-4 board, but the methods are more complicated.

You can position the layers on both sides of the core in a sandwich formation or stack them vertically.

Drilling conductive holes through the board is possible allowing you a path between the layers.

A multilayer employs prepregs to isolate the conductive stratums and mechanically support the structure.

Chip a Bordo

The MCPCB LED Chip a Bordo exists in applications that require thermoelectric isolation.

This MCPCB LED structure has a single conductive copper layer, a dielectric layer, and a metal base.

The structure of the layer structure in a chip-on-board bears similarity to single layer with the difference highlighted in thickness.

A chip between the layers over the metal base, permits separation for thermoelectrically.

Why Is Symmetry An Essential Aspect In MCPCB LED Layout?

For a multilayer MCPCB LED, symmetry is essential.

When employing a multiple set-up with a metal core, symmetry refers to a similarity in layer arrangement.

When arranging a metal core board, you need to ensure the layer counts on either side are even in form and structure.

You should therefore achieve similar thickness over and below.

For a six layer board, for instance, you have three layers each above and beneath the metal backing.

An MCPCB LED arranged in this manner avoids warpage, which might result in poor performance or board damage.

Is The Use Of Through-Holes In MCPCB LEDs Necessary?

Furnishing your metal core board with orifícios de passagem especially plated ones is not essential.

You find using these PTHs is a major cause of electrical shorts on such a board.

Empregando SMT is therefore more convenient since you do not require to attach them through the board.

However, sometimes it is necessary to feature PTHs in your set-up.

In this case, present the PTHs such that they are clear from the metal core preventing a conflict n functionality.

You can make holes with a wider diameter to those of the PTHs.

How Is The MCPCB LED Soldering Process?

Surface mounting technology finds wider usage than through-hole mounting for populating an MCPCB LED.

Because of the possibility of shorts caused by holes and metal backing, using through-hole mounting in MCPCB LEDs is difficult.

As a result, if you require through-hole installation, keep the holes and metal core separate.

What’s more, using a few plate holes reduces the difficulty of effective separation and the possibility of shorts.

Reflow soldering is the most frequent type of soldering procedure for surface-mounted components. Here, you pass the board through a reflow oven to attach components to the MCPCB LED.

Can You Have Surface Finishes on MCPCB LEDs?

You can employ various surface finishes on an MCPCB LED.

Acabamentos de superfície PCB protect the copper circuitry from corrosion while also improving the solderability of the board.

Some of the common surface finishes applicable on an MCPCB LED are:


The HASL surface finish is a common circuit board finish.

To cover all exposed copper surfaces with solder, you submerge the MCPCB into a molten solder bath.

By passing the board between hot-air knives, you separate excess solder usually a tin-lead alloy.

HASL provides superior wetting while allowing an extended processing window.

Immersion Silver (ImAg)

Immersion silver protects copper traces from corrosion by plating a lead-free coating of silver onto the MCPCB.

With an electroless immersion reaction, silver surface finishes attaches to copper traces, displacing the copper layer.

HASL sem chumbo

Lead-free HASL employs a similar process to HASL only that it eliminates use of lead to comply with RoHS requirement.

You find this finish is ecofriendly and can highlight issues of delamination through high temperature exposure.

Conservante de soldabilidade orgânico (OSP)

OSP is a water-based organic surface treatment that you utilize on an MCPCB LED’s copper pads.

Prior to soldering, it selectively attaches to the copper and shields the copper pad.

OSP is ecofriendly since it is lead-free and provides a flat surface that you can easily rework.

However, using this finish for plated through-holes is challenging and it has a reduced shelf-life.

What Tests Are Applicable On An MCPCB LED?

Testing an MCPCB LED is essential in ensuring your board achieves performance efficiency without infantile damage.

Additionally, when you test your board you save on costs by capturing errors and faults before roll-out.

Some of the common tests you use for an MCPCB LED are:

Teste Burn-In

The burn-in testing seeks to determine load capacity and detect early breakdowns.

O teste de queima pode ser prejudicial às peças em teste devido à sua intensidade.

Burn-in testing involves putting a lot of power through your electronics, usually to its maximum capability.

You continually run power through the board for between two and seven days with failure termed infant mortality.


AOI takes images of the MCPCB LED with either a single 2D camera or a pair of 3D cameras.

After that, the computer compares your PCB’s images to a thorough schematic.

If a board fails to match the schematic to a particular extent, you tag the board for inspection.

AOI can be helpful in discovering problems early so that production can be stopped down as soon as possible.

Inspeção por Raios-X

This test is more of an inspection tool available in 2D and 3D formats, with 3D providing a shorter testing period.

A technician does this test to discover problems early in the manufacturing process by looking at soldered connections, traces and barrels.

Why Use MCPCBS For LEDs?

Light applications generate heat, which must be evacuated in order for the system to function properly. LEDs generate heat in lighting applications, and employing MCPCBs intervenes with regard to successful heat dissipation.

When you use an MCPCB to make your LED, you get the following results:

  1. Longevidade: There is no thermal build-up on the board surface with an MCPCB, thus no thermal strain. Your LED will therefore have a longer service life.
  2. Higher LED Density: Achieving high thermal conductivity is possible when you use an MCPCB. You can implement extra light emitting diodes without impairing the circuit board’s performance in heat dissipation.

What Engineering Aspects Are Applicable For MCPCB LEDs?

There are several aspects you need to consider when developing an MCPCB LED central to its performance.

Some of the major engineering and design aspects are:

Impedância Controlada

This process matches MCPCB LED substrate material properties to the conductive track dimensions and locations.

This guarantees that the trace signal’s impedance is within a given percentage of a predetermined value.

Verificações de regras de design

These are guidelines you employ to guarantee a match between the schematics, manufacturing concerns and dimensional tolerances of MCPCB LED.

To accommodate diversity, design rule check allows use of error margins.


DFM is the process of designing MCPCB LED parts, components, or products for ease of manufacture. The end objective is to produce an improved product at a lower cost through simplification, optimization, and refining of the design.

Why Is It important To Have An MCPCB LED?

Lighting technologies incorporating LEDs experience significant heat rises especially when utilizing high power.

Where you install such LEDs on printed circuit boards is extremely important to consider.

Utmost care is vital in the presentation of circuit boards in these LEDs without which you will experience difficulties in performance.

Such difficulties can manifest as functional problems or outright damage causing costly losses.

In these cases, using an MCPCB LED helps you to properly dissipate heat, reducing the risk of board damage.

Direct heat transfer can be effective in conductively cooling an MCPCB LED.
