High-touch PCB design, development, and Aluminum PCB manufacturing services at low-cost prices.
Aluminum PCBs resemble standard PCBs; the distinction lies in the base materials. Aluminum PCBs contain Aluminum base materials, which have high thermal dissipation capacity, durability, and dimensional stability.
Standard boards cannot withstand high temperatures. Instead, they easily bend when exposed to high heat-dissipation conditions. Thus, Aluminum PCBs are valuable ingredients in such working conditions.
Aluminum circuits have unique metal-based copper-clad laminates. These laminates give them high heat conductivity, electrical insulation, and excellent machining performance. Aluminum circuits are typically classified into single-sided Aluminum PCB, double-sided Aluminum PCB, Flexible Aluminum, Mixed Aluminum PCB, and Through-hole Aluminum PCB based on the design structures and applications.
While all Aluminum clads work the same way, particularly in heat dissipation, different types have individual features based on their design and structure. There are 4 main types of Aluminum boards:
When designing a Through-hole Aluminum board, the manufacturer backfills, and pre-drills one aluminum layer before applying the laminate material. This leads to the formation of a multilayer structure core. Afterward, the manufacturer laminates the thermal materials on both PCB sides with thermal bonding materials.
Multilayer Aluminum boards contain several layers of thermally conductive dielectrics. The design comprises one or more circuitry layers in the dielectric with blind vias acting as thermal vias.
Here, the insulating layer is made of an epoxy resin material. The epoxy resin displays high thermal conductivity.
High-Frequency Aluminum boards have insulating layers made of polyolefin or polyamide materials. Sometimes, the coating contains woven fiberglass between the epoxy resins.

Among the metal core printed circuit boards (MCPCBs), known for their capacity to offer high thermal dissipation, Aluminum PCB is the most common type. Generally, its base material is made of an aluminum core with standard FR4 materials. It contains a thermal clad layer that dissipates heat efficiently, cooling PCB components and enhancing their overall performance.
Currently, engineers mostly recommend Aluminum PCBs for high-power and tight tolerance applications.
MKTPCB has been fabricating aluminum circuits for more than ten years. Our full-featured metal core PCB manufacturing capacity and a thorough quality inspection process enable our customers to obtain high-quality products at competitive market prices. Our Aluminum PCB products are mainly used for LED lighting, power equipment, and automotive systems.
Aluminum boards are lightweight; hence, they fit the modern consumer demands for miniaturized products. Additionally, Aluminum metal is durable and contributes to the resilience and durability of a circuit board.
If your application calls for strength and a long lifespan, you can use Aluminum as your base material. It minimizes PCB breakage that may arise during daily use, production, and handling.
Aluminum is a common metal worldwide. The easy availability makes it a more cost-effective solution compared to other base materials.
The performance of most electronic products is adversely affected by high temperatures. Aluminum is an excellent thermal conductor that helps to dissipate heat away from vital PCB components. This ensures that the products function effectively even in adverse thermal conditions.
Compared to standard FR4 boards, Aluminum PCBs display better heat dissipation performance. For instance, an FR4 PCB with a thickness of 1.5mm has a heat resistance of 20-22 degrees per watt, while an Aluminum board with a depth of 1.5mm will display a thermal resistance of 1-2 degrees per watt.
Every PCB base material has its thermal expansion coefficient. The CTE of Aluminum (22ppm/C) and copper (18ppm/C) are pretty close. Since Aluminum boards have high thermal dissipation properties, they do not experience significant expansion and contraction problems. They function efficiently and are durable and reliable.
Aluminum printed circuit boards display high dimensional stability. For instance, when they are heated from 30-140 degrees, their size changes by 2.5%-3.0%.
You can use Aluminum boards in power device SMT. They are suitable for power devices because of their thermal expansion and circuit design performance. They prolong product shelf life and product power density. Besides, you can use them to reduce the overall product volume.
