Silicon-based technology developer Dow Corning has released new dispensable thermal pads for more cost-effective thermal management in LED lighting applications.
The new dispensable thermal pads “enable LED lamp and luminaire manufacturers to quickly and precisely print a layer of thermally conductive silicone compound in controllable thicknesses on complex substrate shapes while ensuring excellent thermal management properties and reduced manufacturing cost,” the company said.
The new product line encompasses four grades with varying levels of thermal conductivity. Dow Corning TC-4015 and TC-4016 dispensable thermal pads offer thermal conductivity of 1.5 W/mK, while Dow Corning TC-4025 and TC-4026 dispensable thermal pads offer higher 2.5 W/mK thermal conductivity. Two grades— Dow Corning TC-4016 and TC-4026 dispensable thermal pads—incorporate glass beads to help improve control over bond line thickness.
The materials can be applied via standard screen or stencil print processes, or using standard dispensing equipment.
