Lead sizes smaller than 0.4mm will not typically be used for thru-hole connections. More often, lead sizes smaller than 0.4mm will be wire bond or by some other methods of connection. Modification to the formula for mounted pads was made. The new formula now looks like; "=IF(0.5*ROUNDUP(3.1*B7,1)-B7<=0.5,B7+0.5,0.5*ROUND(3.1*B7,1))". This accomidates the smaller lead sizes meeting the 0.5mm minimum annular ring required by IPC for manufactureability as seen in Tables 9-1 and 9-2 in IPC-2221

Finished hole size was reduced from 0.3mm over max lead size back to 0.2mm in matching IPC-2222 Table 9-3
