Folks,

First a finding of interest to be sharred (one or two r's, never get this
right - and I'm writing a book!) with all BGA/CSP officianados (haven't a
clue how to spell that). Witnessed the strangest electronic packaging thing
ever in my young and tender life the other day.

A small, but very much on the rise non-manufacturing oriented telecom
company (how about that for irony in these times), with whom I'm currently
consulting, demonstrated a new way to assure circuit continuity. Boards are
suspect and assemblies don't seem much better (why I'm here). Finger
pressure on BGA device top and electrons flow and circuit "works." Finger
gets hot and tired. Engineer uses woodworking "C" clamp to do the finger's
work. Electrons flow. Just thought few of you could top this story.

I do love this work so.

This brings to mind another request. I have associations with several good
fab shops. Hope Glynn Shaw is looking in and would like to build some quick
turn 12 layer boards. Don't know a single good PCBA capability wanting to
do protos and medium volume production assemblies with .8 csp's and a
couple of FPGA's as one a perimeter and another a full array metal top
variety (you all know the ones. If anyone knows of this type assembler, in
the northern Ohio area, please let me know. I am a born again "HARD"
supplier qualifier, however.

Earl Moon ---- and don't leave home without your c clamps and a little wood
for top and bottom insulators. I think balsa is best. Maybe IPC has this
covered.
