LED Heatsinks with Low Temperature Solderable (LTS) Copper Coating   

   HAIHONG® Low Temperature Solderable (LTS) copper coating has successfully made it possible for the high power LED package to directly be soldered onto heatsinks made from aluminium. HAIHONG® Low Temperature Solderable (LTS) copper coating technique is the ideal solution to the degradation of heat conduction performance of thermal interface material (TIM) between integrated chip LED package and heatsink. The using of integrated chip LED package is benefit to design LED lighting at its very best optical performance.

COPETITIVE ADVANTAGES:
 A thin copper coating is strongly bonded to the soldering required area on the surface of aluminium heatsinks;
 The contact thermal resistance is eliminated through the soldering of high power LED package directly onto aluminium heatsinks;
 The heat conductivity of lead-free soldering material (~50W/m.K) is 10 times higher than that (~5W/m.K) of the best thermal interface material (TIM);
 The alloying combination of dissimilar materials between copper and aluminium prevents debonding from thermal stress and chemical corrosion;
 The enhanced heat transfer from direct soldering can significantly reduce required heat dissipation area of aluminium heatsinks at the desired LED operation temperature;

REQUIREMENTS OF LED PACKAGE:
Integrated LED chips mounted on electric insulated copper heat spread slug.
APPLICATION:
Outdoor lighting: LED high bay lights, LED street lights, LED flood light, LED tunnel lights
