AL9646 Aluminum Alloy Polystyrene Composite Substrate

Aluminium Alloy Polystyrene Composite Substrate Description

The Aluminium Alloy Polystyrene Composite Substrate combines a thermoplastic polystyrene core with outer layers of 1050 and 1060 aluminium alloys. This structure enhances electrical insulation while preserving the metallic attributes essential for structural applications. The controlled bonding process maintains uniform layer thickness and adhesion, which is critical for achieving the target thermal conductivity and corrosion resistance. Such a configuration meets the demands of industrial environments where material stability is required.

Aluminium Alloy Polystyrene Composite Substrate Applications

Electronics and Semiconductor Applications
• Used as a thermal management platform in power modules to achieve efficient heat dissipation by leveraging the high thermal conductivity of aluminium alloys, reducing device overheating.
• Applied as an insulating layer in printed circuit boards to avoid electrical shorts by utilising polystyrene's dielectric properties, enhancing circuit reliability.

Industrial and Structural Applications
• Serves as a component in sensor housings to prevent corrosion damage by using the composite’s layered structure, thereby extending sensor lifespan.
• Applied as a mounting substrate in automation systems to achieve stable alignment by employing its controlled thickness and uniform bonding.

Aluminium Alloy Polystyrene Composite Substrate Packing

The substrates are individually sealed in anti-static, moisture-resistant packaging and cushioned within foam-lined containers to prevent mechanical damage. They require storage in a dry, temperature-regulated environment to minimise material stress and particulate contamination. The packaging design includes anti-scratch measures and may be customised for additional humidity control or compartmentalisation to meet specific handling and storage conditions.

Frequently Asked Questions

Q1: How does the dual-material composition enhance performance in thermal applications?
A1: The integration of a polystyrene layer with high-purity 1050 and 1060 aluminium alloys creates a balance between electrical insulation and heat dissipation. This dual-material approach reduces thermal stress and counteracts rapid temperature fluctuations in demanding operational environments.

Q2: What quality control processes are applied during substrate production?
A2: SAM utilises controlled thermal bonding alongside spectral reflectance analysis to monitor layer uniformity and adhesion. In-line inspection and batch testing measure electrical insulation properties and dimensional tolerances to ensure the material meets defined industrial standards.

Q3: Can the substrate’s layer thickness be customised for specialised applications?
A3: Yes, substrate layer thickness can be adjusted based on customer specifications. Modifications in the layering process allow for tailoring electrical insulation and thermal management properties, accommodating diverse industrial requirements.
