Hi Sanjay!
     
    If things haven't changed, it was +/- .004" for QFP's last time I checked.
As far as lead tinning houses go, there are two out here in the silicon valley 
that I know of:
     
Six Sigma - Phone: (408) 986-0300 
     
My comments:
"Good shop, did some .031" pitch 32-pin CQFP devices for me a while back with 
very good quality..."
     
     
     
Pacific Semiconductor Technology - Phone: (408) 492-1911
     
My comments:
"Okay shop, screwed-up the first batch of some of the same devices above. They 
needed *VERY EXPLICIT* instructions back then, but after that, they put out good
work...things may have changed for the better since back then"
