(depends on the soldermask registration tolerance) Stencil opening 0.300 mm aperture diameter Stencil thickness Between 0.100 mm and 0.125 mm Pad trace width 0.100 mm 7.10.1 Device marking for UFBGA176+25 The following figure gives an example of topside marking versus pin 1 position identifier location. The printed markings may differ depending on the supply chain. Other optional marking or inset/upset marks, which depend on supply chain operations, are not indicated below. Figure 111. UFBGA176+25 marking example (package top view) STM32H7B3 IIK6 Y WW Revision code Product identification(1) Date code Ball 1 indentifier 1. Parts marked as “ES”, “E” or accompanied by an Engineering Sample notification letter, are not yet qualified and therefore not approved for use in production. ST is not responsible for any consequences resulting from such use. In no event will ST be liable for the customer using any of these engineering samples in production. ST’s Quality department must be contacted prior to any decision to use these engineering samples to run a qualification activity. 7.11 Thermal characteristics The maximum chip-junction temperature, TJ max, in degrees Celsius, may be calculated using the following equation: TJmax = TAmax + (PDmax × ΘJA) Where: STM32H7B3xI Thermal characteristics DS13139 - Rev 8 page 219/238 |
