Open-cavity QFN die-fit check, step by step: die-attach area, cavity depth, pad count and pitch with real ALNP dimensions
**Short answer:** A die fits an open-cavity QFN when four checks pass. The die X and Y must be no larger than the nominal die-attach area. The die thickness plus attach material and wire-loop height must stay below the cavity depth. The die
