BGA decal with via

[Tahir]

Hello everyone
I made a BGA decal (with via in decal) in Power PCB. Some of
via were up (south) from pad and some were down (north)
of pad. When performed JEDEC pinning, A8, B8, E8 were missing.
Does anyone know what is the problem. Thanks

PowerPCB assumes you have straight BGA (no spaces) when it assigns JEDEC pin assignments. If you do have spaces it automatically skips them and continues.

I guess the best way to explain this is that you cannot assign JEDEC pin numbers when you use the North South East West technique.

You have to manually fix the Alpha/Numeric pin assignments in the Part-Type.
