DIY Copper Shims for Laptop Chips
These copper shims measure 15mm by 15mm and 0.3mm thick, supplied in a pack of 10. They are intended for DIY cooling of laptop BGA CPUs, VGA chips, RAM and other ICs where a thin thermal interface is required.
High Thermal Conductivity Under Load
The shims offer a stated thermal conductivity of up to 401 W/m·K, far above ordinary copper at 20 to 30 W/m·K. This helps move heat away from the die continuously during sustained workloads rather than relying on thermal pads that can degrade over time.
Check Clearance and Surface Flatness
Verify that the target components have enough vertical clearance for a 0.3mm shim and that the mating surfaces are flat enough to make full contact. Builders needing thicker gaps or larger footprints will need a different solution.

Questions about this item
How much heat does a 15x15x0.3mm copper shim move when the laptop runs all day?
Each shim conducts up to 401 W/m·K, far above ordinary copper at 20–30 W/m·K, so it spreads sustained load heat quickly without adding noise or power draw.
What else must I already have to install these 10 copper shims on a laptop BGA chip?
You need thermal paste or pads to fill gaps, a clean workspace, basic disassembly tools for your laptop, and the existing heatsink or heat-pipe assembly that will press against the shims.
Will these 0.3 mm shims work alongside the original thermal plastic on an older GPU or RAM IC?
Yes — the shims replace aged thermal plastic that loses conductivity over time, restoring contact between the chip and the original cooler without changing the mounting pressure.
