Copper Shim Heatsink for Laptop Chips

This pack contains ten copper shims measuring 15mm by 15mm with a 0.5mm thickness. They are designed to transfer heat from BGA CPUs, GPU chips and memory ICs inside laptops. The copper material offers a thermal conductivity rating of 401 W/mK. Each shim replaces aged thermal pads that have lost effectiveness.

Check Chip Height and Clearance Before Fitting

Measure the gap between the die and the heatsink contact plate to confirm a 0.5mm shim fills the space without excessive pressure. Verify that the 15mm square footprint covers the target component without overlapping neighbouring parts. Ensure the mounting mechanism can accommodate the added rigid layer.

Fits Between Die and Cooler in Tight Stacks

The shim sits directly on the chip surface and conducts heat to the existing cooler assembly. It eliminates the need for thick thermal pads that degrade over time. The rigid copper layer maintains consistent contact pressure across the die. Ten pieces allow multiple chip coverage or spare units for future maintenance.

Questions about this item

What is included in the 10-piece pack and do I need thermal paste or pads separately?

The pack contains ten 15 mm × 15 mm copper shims at 0.5 mm thickness; thermal paste or pads are not included and must be purchased separately.

The listing mentions both 0.5 mm and 0.6 mm — which thickness should I choose?

The shims measure 0.5 mm thick; the 0.6 mm figure appears only in the supplier title, so use the 0.5 mm specification when planning your stack height.

What does the 401 W/m·K conductivity figure mean for my laptop GPU or CPU temperatures?

It indicates the copper shim conducts heat far better than standard copper (20–30 W/m·K), helping spread heat from BGA chips to the heatsink more efficiently.
