? It ? is ? recommended ? that ? the ? lead ? lands ? are ? Non ?
Solder ? Mask ? Defined ? (NSMD). ? The ? solder ? resist ?
should ? be ? pulled ? away ? from ? the ? metal ? lead ? lands ?
by ? a ? minimum ? of ? 0.025mm ? to ? ensure ? NSMD ?
? Ensure ? that ? the ? solder ? resist ? in ? between ? the ? lead ?
lands ? and ? the ? pad ? land ? is ?≥? 0.15mm ? due ? to ? the ?
high ? aspect ? ratio ? of ? the ? solder ? resist ? strip ?
separating ? the ? lead ? lands ? from ? the ? pad ? land. ?
pads. ??
? The ? land ? pad ? should ? be ? Solder ? Mask ? Defined ?
(SMD), ? with ? a ? minimum ? overlap ? of ? the ? solder ?
resist ? onto ? the ? copper ? of ? 0.05mm ? to ?
accommodate ? solder ? resist ? misalignment. ?
