Stefan,
My attempt to wipe off the excess did not go well.
Apparently once the Solder Balls & Flux have melted (and burned off
the Flux) they really don't want to go any where.
Luckily, I was just experimenting with a portion of this small board.
All I managed to do was to create a bunch of solder bridges.
So, after I removed them all with a razor blade, I decided to stop
while I am ahead. The board is functional. I am going to go ahead
and solder components to it, and be done with it.
But, in order to benefit from what I have learned, and have it
burned into memory...I am going to start all over again. With a
fresh board. And make a second, identical circuit. And this time, I
will:
1. etch with the board held vertically. And with a better bubbler
running across the ful length of the board.
2. Be sure to wipe off the excess solder paste...while it is STILL
in its grey-colored state (BEFORE it has turned into solder.)
Hmmm...maybe I will wait on populting that first board...:-)
