20-VQFN package — thermal pad and rework notes
Housed in a 20-VFQFN Exposed Pad package, supplier device package 20-VQFN (3.5x4.5 mm). Surface-mount assembly with Tape & Reel (TR) packaging — standard for high-volume pick-and-place. The small QFN footprint requires careful stencil design for the center pad solder coverage.
