Phase changing thermal interface material alloy created in-situ

The method of 16, wherein the liquid TIM alloy has a solidus temperature below 20° C.

A liquid thermal interface material (TIM) alloy formed by a process, the process comprising:

• forming an assembly comprising multiple solid metal TIMs between a first device and a second device such that a first surface of the solid metal TIMs is in touching relation with a surface of the first device, and a second surface of the solid metal TIMs opposite the first surface is in touching relation with a surface of the second device, the solid metal TIMs comprising a first solid metal TIM and a second solid metal TIM;
• and
• forming the liquid TIM alloy from the solid metal TIMs by heating the assembly above a first solidus temperature of the first solid metal TIM, the liquid TIM alloy having a second solidus temperature below the first solidus temperature

A method, comprising:

• placing a solid gallium or gallium alloy thermal interface material (TIM) between a heat generating device and a heat transferring device to form an assembly such that a first surface of the solid gallium or gallium alloy TIM is in touching relation with a surface of the first heat generating device, and a second surface of the solid gallium or gallium alloy TIM opposite the first surface is in touching relation with a surface of the heat transferring device;
• and
• after placing the solid gallium or gallium alloy TIM, activating the heat generating device to form a liquid gallium or gallium alloy TIM from the solid gallium or gallium alloy TIM.
