[hpsdr] Resoldering the ADC on Mercury

[Todd Mondragon]

Hi all,

I seem to have one of the Mercury boards with soldering issues on the ADC
heatpad.
11 of the 34 holes show no solder flow at all (most are around the edges
with 2 in the middle of the pad). I have not hooked it up yet to check the
temperature but I suspect this may be enough of a sign that I'd want to
reflow the ADC heat pad anyway.

What would be the best method to make sure I've got a good contact between
the board and chip and that I have have all the heat pipes soldered through,
those holes are pretty small! Unfortunately all I have at my disposal for
this work is a pencil iron.

Or is the experience of the group such that there shouldn't be a problem and
that I should not worry about it?

BTW - This is no reflection on the folks at TAPR or anyone else, I
completely understand this is an experimenters kit and have no problem
fixing any issues I may encounter on my own. The folks at TAPR and the
people who designed and made this equipment possible are tops in my book.

73!
