This is part of an experiment for Kim S at IPC for a defect blog for the
website. So thought I would pick up on a TechNet question to see if it
worked OK with the "Strawberry" users?

See my feedback video www.bobwillis.co.uk/videoclips/DrBob180QFNLGA.wmv

Subject: Re: [TN] Actel QFN180 Assembly

Coming back on an old post from Steve (at his former employer...).
Does anybody have good stencil rules for the assembly of multi-row QFNs and 
especially triple-row such as ACTEL QFN180?
Like Steve and probably many others, we tried to find the right aperture 
balance between I/Os and central thermal pad without success...
