7.1.1. Bond Line Thickness (BLT)

Bond line thickness (BLT) is a minimum required thickness with adequate coverage, uniformity, contact, and pressure to ensure efficient heat transfer. Proper contact between the heat sink and package top surface must be achieved while minimizing the thermal interface material (TIM) thickness. Ideal bond line thickness can vary depending on the specific application and type of TIM.
