Aluminum substrate is a metal based copper clad plate with good heat dissipation function. Let Shenzhen circuit board manufacturers take you to understand the types of aluminum substrates.
1. Flexible aluminum substrate
With excellent electrical insulation, flexibility, and thermal conductivity, products can be formed to achieve various shapes and angles, and eliminate expensive fixing devices, cables, and connectors.
2. Mixed aluminum substrate
The 2-layer or 4-layer components made of traditional FR-4, which are then bonded to an aluminum substrate with a thermoelectric medium, help dissipate heat, improve rigidity, and serve as shielding.
3. Multilayer aluminum substrate
Made of multiple layers of thermal conductive dielectric, with one or more layers of circuits embedded in the dielectric, blind holes used as thermal through holes or signal pathways.
4. Through-hole aluminum substrate
Before lamination, aluminum is pre plated and filled with dielectric. Thermal materials or sub components can be laminated onto both sides of aluminum using thermal adhesive materials. Once laminated, the completed component is similar to a traditional multi-layer aluminum substrate, with electroplated through holes passing through the gaps in the aluminum to maintain electrical insulation.
In PCB production, aluminum substrate belongs to special sheet metal, which has a certain technical threshold and operational difficulty, and the cost is also high. Therefore, it is important to find a professional and suitable circuit board manufacturer. The above is the type of aluminum substrate that Shenzhen circuit board manufacturers have shown you, hoping to be helpful to you.
