(cannot) have a side fillet. But Chip Capacitors have metal Terminals on 5 sides and a side fillet is a reality. IPC-7351 is no longer a Standard

0.05 mm because the hot solder runs out to the Toe, Heel and Side fillet. But the thermal tab is floating on 0.125 mm of solder. The rule is simple. If the terminal lead pad does not have a Toe, Heel and Side fillet then it requires paste mask reduction so that the final result post reflow oven is about
