Our C1100 Copper Fin Aluminum Heatsink is a high-performance composite thermal management component, innovatively combining C1100 red copper fins (for superior heat transfer) with aluminum substrate (for lightweight and cost-effectiveness), tailored for electronic devices requiring efficient heat dissipation and reliable assembly.

 

 

The C1100 copper fins-made of 99.9% pure red copper-boast exceptional thermal conductivity (390 W/m·K), enabling rapid absorption and conduction of heat from high-power electronic components. The aluminum substrate, with its lightweight and excellent mechanical strength, reduces the overall weight of the heatsink while ensuring structural stability, making it suitable for weight-sensitive applications. To enhance corrosion resistance, solderability, and electrical conductivity, the heatsink undergoes professional nickel plating treatment on the surface, forming a dense, uniform nickel layer that effectively prevents oxidation and corrosion.

 

Additionally, the tin soldering process ensures firm bonding between copper fins and aluminum substrate, eliminating thermal resistance gaps and ensuring efficient heat transfer from fins to substrate. As an origin factory, we implement strict quality inspection at every production stage, from raw material selection to nickel plating, tin soldering, and final assembly, ensuring each product meets international standards and client requirements. We also offer flexible customization for fin density, size, nickel plating thickness, and tin soldering specifications, fully adapting to your unique application scenarios.

 

 

 

 

C1100 Copper Fin & Aluminum Substrate Composite Design:

The combination of 99.9% pure C1100 copper fins (superior thermal conductivity) and 6063-T6 aluminum substrate (lightweight, cost-effective) achieves an optimal balance of thermal performance and cost. Compared to full-copper heatsinks, it reduces material costs by 30% while maintaining 85%+ of the thermal efficiency; compared to full-aluminum heatsinks, it improves thermal conductivity by 40%, effectively solving the heat dissipation problem of medium-high power electronic components.

 

Professional Nickel Plating for Enhanced Performance:

The entire heatsink surface undergoes strict nickel plating treatment, forming a dense, uniform nickel layer that enhances corrosion resistance (passing 1000+ hours salt spray test), prevents oxidation, and improves electrical conductivity. The nickel plating layer also enhances the heatsink's solderability and wear resistance, ensuring stable performance in humid, corrosive industrial environments and extending product service life.

 

High-Quality Tin Soldering for Zero Thermal Resistance:

We adopt advanced tin soldering technology to bond copper fins and aluminum substrate firmly, eliminating gaps between the two materials and avoiding thermal resistance caused by poor bonding. The high-temperature tin solder ensures strong bonding strength (shear strength ≥15 MPa), with no risk of detachment even in high-vibration or high-temperature environments, ensuring efficient heat transfer from fins to substrate.

As the origin factory, we adhere to a standardized, professional production process, focusing on every detail from raw material selection to finished product delivery, ensuring the quality and performance of each C1100 Copper Fin Aluminum Heatsink. The key production steps, highlighting nickel plating and tin soldering processes, are as follows:

 

Raw Material Selection & Strict Inspection:

We select high-purity C1100 red copper sheets (99.9% pure) and 6063-T6 aluminum alloy sheets, conducting strict testing for thermal conductivity, purity, and mechanical strength. Unqualified raw materials are rejected to ensure the foundation of product quality.

 

Copper Fin & Aluminum Substrate Machining:

The C1100 copper sheets are cut and formed into fins of specified thickness and density using precision cutting equipment. The aluminum sheets are machined into substrates with required size and flatness through CNC milling, ensuring the bonding surface is smooth and clean for subsequent tin soldering.

 

Pre-Treatment for Plating & Soldering:

The copper fins and aluminum substrate undergo degreasing, pickling, and activation treatments to remove surface oil, oxide, and impurities. This step ensures good adhesion of nickel plating and tin soldering, preventing bonding failure and oxidation.

 

Professional Nickel Plating Process:

The pre-treated heatsink components are placed in an automated nickel plating tank, with precise control of plating temperature, current, and time to form a uniform, dense nickel layer (2-5 μm). After plating, we conduct thickness detection and adhesion testing to ensure the nickel layer meets standard requirements.

 

High-Precision Tin Soldering:

The nickel-plated copper fins and aluminum substrate are bonded using high-temperature tin solder (Sn63/Pb37 or lead-free solder) through automated soldering equipment. The soldering temperature and time are precisely controlled to ensure firm bonding, zero gaps, and no solder overflow, eliminating thermal resistance.

 

Post-Soldering Finishing & Inspection:

After soldering, the heatsink undergoes trimming, polishing, and cleaning to remove burrs and excess solder. We then conduct comprehensive quality inspection, including dimensional measurement (3D laser scanning), thermal conductivity testing, nickel plating thickness detection, tin soldering bonding strength testing, and corrosion resistance testing.

 

Packaging & Factory Direct Delivery:

The qualified heatsinks are packaged in anti-oxidation, shock-proof packaging to prevent damage and oxidation during transportation. As the origin factory, we cooperate with global logistics partners to provide door-to-door delivery services, ensuring on-time arrival and reducing your procurement costs.
