Fellow TechNetters:
Can someone shared their experience with calculating lead to hole ratio
as per IPC-2222 Figure 9-3?
I have a cross section in which I suspect the lead diameter cause
insufficient solder fillet.
I need a QUICK GUIDE to determine this relationship without being
complicated.
Rough drill size: 0.000376
Plated barrel size: 0.003432
Lead size: 0.002047
Victor.
