7.1.3. Package Loading

Package loading refers to the force applied to the semiconductor package, typically by the heatsink or heat spreader, to ensure good thermal contact between the lid and the cooling solution.

Achieving the right package loading is essential for attaining the desired bond line thickness (BLT) and optimizing thermal interface material (TIM) performance.

There are two constraints that must be met for package loading design:

  • The load must be sufficient to ensure that the BLT is optimal.
  • The load applied should not exceed the specified package load limit to prevent die or solder ball cracking.

These constraints can be addressed during the design stage by considering the impact of design tolerances (both for the package and thermal solution) on the overall package load.
