Thermal efficiency for high-performance demands

This Amkor developed family of power IC packages significantly increases the thermal efficiency of power constrained standard Low-Profile Quad Flat Pack (LQFP) and Thin Quad Flat Pack (TQFP) packages. Exposed (ePad) LQFP/TQFP (also known as HLQFP/HTQFP) can increase heat dissipation by as much as 110% over a standard LQFP/TQFP, expanding the margin of operating parameters. ePad can also be connected to a ground, reducing loop inductance for high-frequency applications. For a multi-chip solution, 3D packaging with die stack process is also available.

ePad LQFP/TQFPs give designers the necessary margin for designing and producing high performing products including communications, storage, wireless, networking, PCs, automotive and other similar applications. GaAs and high-speed silicon technologies work well in ePad LQFP/TQFP packages due to additional shielding and grounding capabilities.
