Hole diameter is limited by pcb thickness usually 2 x pcb thk.

Hole density is limited by fab tolerance usually .01“ SN63 Solder paste water clean Use .02“ oversize solder templete .03“vias T = 72c .02“vias T = 75c .012“vias T = 67c Vds = 7.0v, IDS = .5amp EPA480C-SOT89 SOT-89: RΘ = 30 C/W A 105C temperature drops between tab and device junction.

A maximum junction temperature of 150c is recommended.
