WebJun 8, 2024 · 1. Center pad paste should only cover 30 to 40% of area using 0.1mm stencils because too much tin will push the IC up during reflow. 2. Keep QFN IC dry and check if you unsolder the non working parts if pads are covered by tin or maybe ther is a thin white corrosion preventing pins from soldering. Webduring assembly reflow (e.g., live-bug). If parts are reflowed in other than the normal live-bug assembly reflow orientation (i.e., dead-bug), Tp shall be within ± 2°C of the live-bug Tp and still meet the To requirements. Otherwise, the profile shall be adjusted to achieve the latter. To accurately measure actual peak package body
