Metal Core PCB – The Completed FAQ Guide

A metal core is a common component used in the construction of a PCB. This is the board’s thickest material. It is frequently available in a variety of thicknesses, but the most common are 1mm, 1.5mm, and 3.2mm. This metal layer keeps the board flat, provides rigidity, and allows mounting hardware to be attached. However, unlike a traditional PCB, the exposed side of the board is not coated with a surface finish, and there is no solder mask.

What Is a Metal Core PCB?

A metal core PCB has a core made of aluminum or copper and can be single or double-sided. Although multilayer PCBs are available, their use is limited due to their complexity and inability to be recycled. Metal core PCBs are better for the environment because they are non-toxic, easy to extract and purify, and less expensive to manufacture than polyimide-coated boards.

Aluminum Core PCB

Aluminum Core PCB

Because they have a metal base, MCPCBs are also known as thermal-conductivity-sensitive printed circuit boards. This base metal conducts heat well and dissipates it. They’re frequently found in LED lighting, communication electronics, and LED-based products. Copper-core PCBs are more expensive than aluminum-core boards, but they perform better.

A stepper mortar allows a metal core PCB to move in small steps. The milling head’s speed can be adjusted, allowing it to drill through the metal substrate without damaging the surface. A copper foil sheet is bonded to a PP dielectric layer during this process. Finally, the one-sided CCL is ready. The process concludes with the second drilling of holes in the cured resin.

Those who work in high-temperature circuits will appreciate a metal core PCB. This material quickly dissipates heat, preventing component damage. It also has higher thermal conductivity than copper-core boards. A metal core PCB is also more expensive than a copper core PCB, so opting for a metal-core board is a wise choice for high-end electronic equipment.

How Is A Metal Core PCB Made?

The creation of a copper-clad laminate, which is a sheet of copper plated with patterns, is the first step in this process. Following that, it goes through external shaping processing, which separates multiple products. Because of moisture absorption from the air, the end face of the copper-clad laminate is cut, reducing its insulating properties. The copper-clad laminate is finally cut after this processing is completed.

Copper Core PCB Manufacturing

Copper Core PCB Manufacturing

Copper-core PCBs are more thermally conductive than aluminum, but they are more expensive and heavier. Copper is not widely used in electronics because it corrodes more easily. Furthermore, copper-core PCBs can incorporate a dielectric polymer layer with high thermal conductivity, allowing them to transfer heat more quickly. Another significant advantage of using metal-core PCBs is that they are safer and more environmentally friendly than plastic-core PCBs.

Choosing the right manufacturer for a metal-core PCB is a difficult task due to the abundance of inexperienced manufacturers in the industry. Check to see if the manufacturer uses high-quality copper and aluminum that can withstand high temperatures while protecting circuit board elements. Additionally, ensure that the manufacturer you select has extensive experience in PCB production. Look for companies that provide a complete documentation package.

When designing a PCB, the metal core is the thickest material on the board. This layer gives the board rigidity, keeps the circuit flat, and provides enough thickness for mounting hardware. The exposed side of the metal plate is not surface finished, and there is no solder mask on the metal-core PCB. The board is then subjected to a second drilling process. This procedure involves drilling holes in the cured resin.

What Are the Metal Core PCB Stack-up?

Metal core PCBs are made with an internal layer of metal and combine traditional PCB materials. Typically, this layer is made of copper or aluminum. The top and bottom layers are separated by a metal core. For MCPCBs, stack-up symmetry is critical. Warping and premature failure will occur if the layers are not evenly distributed. The advantages and disadvantages of MCPCBs are listed below.

First, the layers are pressed. Next, the inner layers are prepared for lamination. After the lamination, the layers are checked for defects using an inspection machine. This inspection machine compares a digital image with the original Gerber file to ensure no defects.

Once the layers are assembled, the circuit board will take shape. It is important to note that the process does not end here. Once the layers are bonded together, they cannot be adjusted once the board is finished.

Metal Core PCB Stack-up

Metal Core PCB Stack-up

A metal layer is deposited over the copper layers during the metal core PCB construction process. Metal core PCBs, unlike standard PCBs, do not have plated through holes. These holes have the potential to cause short circuits in the bottom layer. Furthermore, solder can enter the vias during the soldering process, resulting in errors. As a result, it is critical to inspect the metal core PCB stack-up to ensure that it adheres to the design guidelines.

Another advantage of metal core PCBs is their ability to efficiently transfer heat from high-power components. Metal PCBs are commonly used in power circuits, LED lighting systems, and automotive applications. This technology improves overall circuit reliability by enabling efficient thermal management.

This means that the boards can outlast the components to which they are attached. The same holds true for the components. When you use a metal core PCB, you can be confident that your circuit will work properly.

The manufacturing process for metal core PCBs differs from that of glass-weave laminates. The PCBs’ metal backing serves as a large ground plane and heat sink. It also aids in shielding and plane capacitance, both of which are critical in high-speed circuits. Furthermore, metal core PCBs can be made of ceramic material, making them an excellent choice for prototyping and testing.

The metal core serves as a heat sink as well. This is advantageous when the board is installed near an electrical source. It is important to remember, however, that when connecting the board to the power source, you should not ground it. You avoid ground loops and direct heat dissipation this way, which helps to keep surface temperatures low. These benefits are driving the popularity of metal core PCBs in today’s electronic circuits.

Complex enclosures and specialty mechanical components are required during the metal core PCB design process. A design tool with native 3D tools for metal core PCBs can assist you in navigating the complex design process. You can also share your metal core PCB designs with other collaborators using the software. You can also use Altium 365, a cloud-based platform for circuit board design collaboration, for metal core PCB design.

What Are the Applications of Metal Core PCB?

A metal-core PCB has numerous advantages in electronic circuits. They provide high thermal conductivity while reducing overall thickness and cost. Furthermore, their rapid heat dissipation makes them ideal for use in defense, aircraft, and submersibles. If you’re unsure about the applications of metal-core PCB, contact a reputable PCB supplier to learn more about the advantages and applications of these circuit boards.

The procedure begins with the creation of a metal-core PCB using specialized software. You’ll want to ensure that the design’s output matches the final product. To create the board, use a design program such as Altium Designer or OrCAD.

After you’ve completed your design, you’ll send a schematic to a manufacturer. Many designers prefer to send their schematics in Gerber format, which preserves the design’s beauty.

The surface finishing options for metal-core PCBs differ. The surface finishing of metal-core PCBs varies depending on the material used, the rate at which the board is assembled, and the surface consistency. Each method has advantages and disadvantages, so it’s best to investigate each one and see which one best suits your needs.

When preparing a metal-core PCB, ensure that all drilling debris is removed from the surface. A hole wall deposit will be unreliable if the drilling debris is not removed.

The primary advantage of a metal-core PCB is its superior thermal dissipation properties. It can effectively dissipate more heat than FR4. High-temperature device design reliability is improved by using metal-core PCBs. The metal core absorbs heat generated by the device and transfers it to the cooler side of the layer without damaging the LED.

What Are the Benefits of Metal Core PCB?

A metal core PCB has several advantages. Its single-sided design is ideal for audio and power supply equipment. A metal core allows power transistors to be mounted directly on the board, saving board space.

Furthermore, a metal substrate can eliminate the need for insulating hardware, improving heat transfer from the circuit to the surrounding environment. It can also allow designers to eliminate entire sections of printed wiring boards and interconnects. Its etching technique enables designers to replace discrete devices with surface mount devices at the board level.

A metal core PCB is an excellent choice for heat dissipation and can be more durable than traditional circuit boards. Its lower density enables it to be used in applications with high switching power, resulting in lower device temperatures. Metal core PCBs, unlike traditional copper-based circuit boards, are resistant to oxidation and high temperatures. Metal core PCBs can also be double-sided for high-advance circuits.

They can be double-sided and layered with other components. Routing can also take place through the metal layer. Multilayer dielectric stacks can be used on one or more layers. Furthermore, the metal layer should be grounded to avoid acting as a monopole antenna. Certain applications may necessitate mourning the metal core to an enclosure.

What is the Difference Between Metal Core and FR4 PCB?

The primary distinction between metal core and FR4 PCBs is their mode of operation. Traces on metal core PCBs do not require vias or large mounting holes. They are manufactured in single layers and proceed directly to circuit imaging without the use of PTH or electroless copper deposition. They are the industry standard for many applications, and both have advantages.

The high thermal conductivity of metal core PCBs is one of their primary advantages. They can function as a grounded-EMI shield as well as a backing layer. However, when using metal core PCBs, you must adhere to the proper design guidelines. PCB layout software, as well as the fundamentals of industry standards, should be the first steps in the process. To understand the differences between metal core and FR4 PCBs, first, understand what they are.

FR4 PCBs are the most common type of PCB. Metal core PCBs are constructed from an aluminum-based base material. Aluminum-based PCBs have a thermal clad layer that effectively dissipates heat and improves overall product performance.

Aluminum PCBs are more commonly used in the LED industry than FR-4 PCBs. Aluminum PCBs have a higher temperature and heat capacity than standard PCB designs.

Another distinction between metal core and FR4 PCB is heat dissipation capability. Metal core PCBs dissipate more heat than fr4 boards. FR4 boards, on the other hand, require a topical heat sink to conduct heat away from the circuit. As a result, FR4 boards are commonly used in products that must operate at high temperatures.
