What are the types of aluminum PCBs?
Even though all-aluminum clads work the same way, i.e., in heat dissipation, different types have individual characteristics based on their design and structure. The following are the types of aluminum clads that you should be knowing.
Through-hole aluminum PCB
When we design through-hole aluminum PCB, the manufacturer backfills and pre-drills a single aluminum layer and then applies the laminate material. There will be a formation of a core of multilayer constructions after this process. Afterward, they laminate the thermal materials on the two sides of the board with thermal bonding materials. The final touch involves drilling on the assembly.
Flexible aluminum PCB
A flexible aluminum PCB is a recently marketed circuit board with a polyimide resin integrated with ceramic filters upon purchase.
The two materials’ essence is to increase insulation, flexibility (you can twist or fold the PCB to any shape and retain the form), and thermal efficiency. What’s more, their application is cost-effective since you won’t need to purchase connectors or cables. It’s disadvantageous because you can’t alter or modify the final product once you acquire a specific shape.
Multilayer aluminum printed circuit board
Multilayer aluminum PCBs have multiple-layer of thermally conductive dielectrics. The design constitutes one or more layers of circuitry found in the dielectric with blind vias representing thermal or signal vias.
An advantage to using multilayer IMS PCB is the straightforward and operative solution they offer for heat conductivity in complex products. Contrary to that, they’re costly and can’t easily engage in heat transfer in single layer designs. Their application is often in power supply products.
High thermal conductivity aluminum PCB
In this type of PCB; the insulating layer is an epoxy resin material. The epoxy resin should have excellent thermal conductivity.
High-frequency aluminum PCB
With high-frequency aluminum PCB, the insulating layer has a polyolefin or polyimide material. Other times, it can be woven fiberglass between an epoxy resin. The purpose of the materials is to improve the flexibility of the PCB.
