Copper shims for BGA chip cooling
These 20 mm square copper shims measure 0.5 mm thick and come in a pack of 10. They are intended for DIY thermal management on laptop CPUs, GPUs and memory chips as well as on Xbox 360, PlayStation 2, 3 and 4 consoles.
Thermal capacity and limits
Each shim offers a rated thermal conductivity of 401 W/m·K, far above the 20 to 30 W/m·K of ordinary copper, so it moves heat quickly from a BGA die to a heatsink. The 0.5 mm thickness provides a thin, compliant interface but cannot replace a full heatsink assembly for sustained high-power loads.
Build integration
The shims sit directly on bare die surfaces and require a mounting solution that maintains even pressure without damaging the package. They free the builder from relying on aged thermal paste or pads that degrade over time, yet they need a separate cooler or heat spreader to dissipate the transferred heat.

| Features | This Copper Shims thermal conductivity up to 401w / mk, and ordinary copper thermal conductivity is only 20-30w / mk CPU and GPU graphics card in the inside part of the laptop using a thermal plastic thermal conductivity, thermal plastic at high temperature for a long time easy to aging, and ultimately lost, leading to overheating of the CPU or GPU, the Laptop will not start after overheating. With this copper pad to greatly lower gpu temperatures, can be used for graphics, northbridge, CPU chips. It can be used as heatsink solution for Xbox ,PS4 and all laptop and computer such as H |

Questions about this item
Will the 0.5 mm copper shims fit between my laptop CPU die and the original heatsink without changing the mounting pressure?
Each shim measures 20 mm by 20 mm by 0.5 mm, so it adds only half a millimetre of height; verify your cooler’s spring tension can accommodate that extra gap before installing.
How can I confirm the shims are transferring heat effectively after I install them?
Monitor CPU or GPU temperatures under load; a noticeable drop compared with the previous thermal pad indicates the 401 W/m·K copper is conducting heat into the heatsink as intended.
Does the pack of 10 shims include thermal paste or adhesive, or must I buy those separately?
The lot contains only the ten copper shims; thermal compound or adhesive tape is not included and must be purchased separately.
