Guy,
What does "two lead thickness means"? If the lead is 0.5mm thickness, then the
gap is 1mm?? How can 1mm can soldered with solder paste which is only 0.1-0.2mm
thick?
Ken

Subject: [TN] L leads soldering question
Hello Technetters,
Is there any requirements regarding the maximum distance between L leads
and the surface of the
pad? I believe that this distance could be considered as dim G in IPC
I've got a board with lifted leads and it
causes the distance between the board and the lead to be more than one
lead thickness (say
about 1.5 leads between the lead and the pad).
