Frequently asked questions
Is it electrically safe near components?
The listing describes it as non-conductive. Still, apply it only where needed, between the chip and heatsink surfaces, and avoid spreading it onto solder pads or connectors.
How should I apply it?
Dispense a small amount onto the centre of the chip surface, then mount the heatsink so the compound spreads evenly. Follow the usage guidance for your specific component.
