QFN Rework and StencilQuik(TM)
The
key to successful QFN rework is the proper "bumping" of the land areas
on the QFN using the correct pattern. BEST has experience in designing
these proper stencil patterns for a variety of differnet QFN IO counts,
sizes and configurations, even when large ground planes exist on the
device. StencilQuik(TM) stencils allow you to successfully and simply
"bump" solder deposits on the part.
Non only does the part need to be properly bumped but these "bumps" need to be properly locatd and placed onto the PWB. StencilQuik(TM) stay in place stencils allow you to easily do this.

 Cannot Believe this Electrical Problem
A
customer called an electrical contractor friend of mine with an
electrical problem. This customer had gone so far as to try
to troubleshoot the source of the problem by taking panel cover of
electrical panel.The customer's problem was that their sump pump wasn't
working as evidenced by the fact that their basement had several
centimeters of water in it. The panel was in the basement and
this customer was playing around with his circuit breakers while
standing in 10cm of water!
Needless to say my contractor friend told the customer he should do nothing - just go upstairs and wait - and hug his kid!.
