Copper shim kit for laptop and console repair

This pack contains ten copper shims measuring 20 by 20 by 1.2 millimetres. They are intended for DIY cooling on BGA processors, graphics chips and memory modules in laptops, Xbox 360, PlayStation 2, 3 and 4 consoles. The shims bridge gaps between dies and heatsinks where thermal paste alone is insufficient.

Thermal capacity and limits

Each shim offers a stated thermal conductivity of 401 watts per metre-kelvin, far above the 20 to 30 watts per metre-kelvin of ordinary copper. The thin 1.2 millimetre profile suits tight clearances in laptop GPUs and console processors, but the fixed thickness cannot compensate for larger gaps or warped heatsinks.

Fixed 1.2 millimetre thickness

The single deciding specification is the 1.2 millimetre height. If your repair needs a thinner or thicker spacer, these shims will not fit. They are sold as a ten-piece lot with no additional sizes included.

Questions about this item

Will the 20×20×1.2 mm shims fit between a BGA chip and the original cooler in my older laptop?

Each shim measures 20 mm by 20 mm and is 1.2 mm thick, a common gap size for many laptop BGA CPUs and GPUs; verify the exact clearance on your board before installing.

How can I confirm the 401 W/m·K shims are making proper contact after installation?

Reassemble the system, run a sustained load and monitor core temperatures; a noticeable drop compared with the previous thermal pad indicates the copper shim is conducting heat as intended.

The pack contains 10 shims — do I need to buy thermal paste or adhesive separately?

The shims are bare copper; you will need a thin layer of thermal compound on each face to fill microscopic gaps, and no adhesive or paste is included in the lot.
