WR Grace's has a Minico product line of conductive inks. You might
want to contact them.

Cy,
Several years ago in the same small town as our company was a
firm called "Additive Technology", or something close. They
called themselves "The Wire Ink People", and were specializing
in reworking life's little "gotchas".
Seems to my addled memory that they were once called upon to add
decoupling caps to a PWB that had caught a case of "Automatic Re-
moval of Components in ECO" combined with a slippery exit ramp,
or maybe I'm recalling a bad dream.
Here's a possible Goose Chase... Two towns away, there is a listing
for something close-sounding. I'd ring them for you, but hey, it's
midnight. Here's the info, *maybe* it's the same folks:
Add Tech Incorporated
330 Boston Rd
Billerica, MA USA 01821
phone 508 553 2121
Alta Vista gives a few clues, Kester has a new product, Ormet 1200,
that is "a new screen printable, electrically conductive and solderable
ink that exhibits excellent conductivity. It is a natural replacement
for hand soldered jumper wires, which have traditionally been used to
modify assemblies. Ormet. is applied before assembly, , making traces
less noticeable, more reliable and aesthetically pleasing." ...
please call 1-800-2-KESTER or fax (847)-390-9338.
See http://www.kester.com/kiver.htm
Another approach might be polymer thick film, but this thread appears
to be geared toward conductive adhesives rather than flow solder.

Hope some of this turns into the head start you sought!
