Abstract
Light-emitting diode (LED) packages and more particularly LED packages with lead frame structures for flip-chip mounting of LED chips are disclosed. Lead frame structures include multiple leads with arrangements for LED chips to be flip-chip mounted across neighboring pairs of leads. Arrangements of stress relief features and anchoring features relative to mounting locations are provided in lead frame structures to enhance mechanical integrity of flip-chip bonds during thermal cycling. LED packages may further include housings that are formed about the lead frame structures. Housings may include a recess with recess floor arrangements for positioning of LED chips.
