I am no so sure...Steve is using polyimide board, which most likely is
for high reliability usage (not off the shelf items for commercial
usage)...I would not use it if it is for avionics (measling cross the
sky is scary...it may infect the stars...)..jk

No. The measling looks quite minor and doesn't come close to other
traces
or pads. Unless I'm mis-judging the scale of the picture, the affected
area
isn't carrying high power either, so I don't see that there's a problem.

Hi ya'll!

I took a few days off last week, and came back to be confronted with
some
boards that have been measled from rework...

Go to: http://stevezeva.homestead.com/index.html to take a peek.

The boards are polyimide, and it obviously appears that there was too
much
heat used when they were reworked...also they may have not been baked
prior

to the rework...I was told that they were, but you know how that goes.

I know what the -610 says about it, it says it's acceptable as long as
the
assembly performs as specified. There isn't any burns or anything around
any
of the barrels, just the measles...and it's only on one 14-pin DIP
location.
Would any of you have any REAL hesitation about accepting this assembly?

Thanks!

-Steve Gregory-
