Soldering heat sink

• Efficient Thermal Bonding: Soldered joints between fins and base provide low thermal resistance for superior heat conduction. ([turn0search1])
• Robust Mechanical Strength: Solder creates permanently bonded, vibration-resistant assemblies ideal for high-reliability applications. ([turn0search1])
• High Fin Density Support: Enables dense fin configurations, improving surface area and forced-air cooling efficiency. ([turn0search1])
• Versatile Material Compatibility: Suitable for aluminum or copper fins and bases-optimized for thermal performance and cost balance. ([turn0search1])
• Extended Product Lifespan: Permanently soldered design maintains integrity over repeated thermal cycles, reducing maintenance needs. ([turn0search4])
• Custom Assembly Integration: Compatible with extruded, folded, stamped or zipper fin heat sink formats for tailored thermal solutions. ([turn0search0])
• ISO Quality Assurance: Manufactured by Sinda Thermal under ISO9001 and ISO14001 standards for consistent product quality. ([turn0search6])

• Material Options: Aluminum or copper fins and base.
• Solder Type: Lead-free/high-reliability alloys.
• Fin Formats: Folded, extruded, zipper, stamped fin types.
• Fin Density: High fin-count configurations for maximum surface area.
• Assembly Technique: Automated or manual soldering ensuring strong thermal and mechanical join.
• Surface Finish: Nickel plating or passivation for corrosion protection. ([turn0search6])
• Size Range: Custom dimensions to cover low-profile to high-dissipation assemblies.
