Aluminium PCB

Aluminum PCBs - Superior Choice From Hitech Circuits

Aluminum printed circuit boards (PCBs) offer distinct advantages over traditional glass fiber PCBs for many applications. As you search for quality and reliable PCB solutions, consider the benefits of choosing aluminum PCBs manufactured by our experienced company.

With over 10 years of experience producing aluminum-based PCBs, we can deliver high-quality circuits to meet various needs. Our aluminum PCBs are commonly used in consumer electronics, computers, industrial controls, and other devices where thermal performance, durability, and reliability are key priorities.

What Sets Our Aluminum PCBs Apart?

Aluminum PCBs stand out from standard PCB materials in a few key ways:

Exceptional Thermal Performance

Our aluminum PCBs enable excellent heat dissipation thanks to the metallic layer. This keeps components cooler and enhances long-term reliability. The metal core offers a lower thermal expansion coefficient than traditional glass fiber laminates.

Lightweight Yet Durable

The aluminum base gives our PCBs outstanding mechanical rigidity to prevent warping or damage over time. And even with this durable construction, aluminum PCBs are lighter than most other options. The weight savings can benefit portability for many applications.

Design Flexibility

Aluminum allows for various configurations, whether you need a simple double-sided circuit or a complex multilayer PCB. We can provide PCBs with 6 or more layers to accommodate complex designs in a compact form factor. The layered construction enables shielding between circuits as well.

Cost-Effective Choice

From rapid prototypes to medium and high-volume production, aluminum PCBs keep costs reasonable thanks to streamlined manufacturing techniques. We've perfected processes for quality results at lower costs than niche PCB materials.

Aluminum PCB Construction

Our aluminum PCBs feature a layered arrangement consisting of the following:

1. Circuit layers: The thin copper layers contain the etched traces, pads, vias, and other conductive features.

2. Dielectric layers: These insulating substrates separate the circuit layers. Common options include polyimide and epoxy composites.

3. Base metal layer: A thick aluminum plate forms the core foundation of the PCB to provide mechanical and thermal advantages.

With this trusted layered construction, we can manufacture aluminum PCBs to suit virtually any application need.

Key Advantages of Aluminum PCBs

Some of the major advantages that aluminum PCBs offer include:

Enhanced Product Reliability

The excellent thermal performance and rigid mechanical design result in more reliable device operation over long duty cycles. Thermal stresses are lowered, and structural integrity is assured.

Higher Power Density

With robust thermal dissipation, aluminum PCBs can accommodate greater power densities than conventional PCB materials. More functionality can be integrated into compact spaces.

Simplified Design

Aluminum PCBs allow complex, multilayer designs to be condensed into simplified boards. Fewer interconnects are required thanks to greater vertical space for traces and components.

Lower Junction Temperatures

The unparalleled cooling capacity minimizes junction temperatures to enhance semiconductor lifespan and reliability. Heat generation is no longer a limiting factor.

Wide Range of Form Factors

From ultra-thin, flexible PCBs to thick designs over 3mm, aluminum enables virtually any geometry requirements to be met.
