Hi,
I need to use a LGA 4x5 28L IC. Routing would be much easier in my applicat=
ion
if I could put some traces beneath the chip (connect Vdd or Vss to this or =
that
input to enable/disable functions through those pins). There's no exposed p=
ad.

Will it be OK or must I route the tracks only externally? I'm afraid of sol=
der
bridges, etc.. expecially as I will hand solder it (the pads will protrude =
and
I'll use a spoon-like tiny soldering tip, I've been successful with QFN chi=
ps).

Thanks for your help, this is the first time I use a LGA chip, no past expe=
rience.
