| Subject: | Re: Board Soldering: Overheating and Cleaning? |
Yesterday I soldered the wires to the transponder board leaving them about 6" long,
which I soldered to a female dsub 15. Also made up the mating male dsub.
At first I tinned the board and wire ends then came back with the iron with a
minimal bead of solder on the tip. It took only a couple seconds to solder them.
I found it was difficult coming back to put more solder after this initial
soldering to make a nice little mound over the wire. I found it worked better
for me to put that extra solder on first, during the board tinning, so I wouldn't
have to come back a second time. I scrubbed the contacts afterwards with a
toothbrush and rubbing alcohol. It's not super pretty, but I'm happy with how
it went.
Grounding
I also needed to run grounds from the transponder to the encoder on the EFIS and
to the common ground buss. My solder cups aren't big enough to put more than
one wire in. Instead of splicing the wires together, I recalled that Bob had
jumped a bunch of dsub solder cups together by placing a section of wire between
them and soldering it all together. I did that for 3 of the cups and connected
ground wires from the transponder and encoder to this. I wanted a 20 awg ground
from the encoder, but only had one spare 24 awg wire left over in the cable.
I used a 22 awg along with this 24 awg wire for this. Diagram below.

Folks,
I'm using Bob's Low Cost Ground Power Jack for your airplane architecture. It
calls out a Tyco W31X2M1G5 5 amp switch breaker for the Ground Power circuit.
I was hoping to include this switch breaker in my row of switches....but I have
a depth clearance issue. The switch breaker is quite a bit more DEEP (2 1/8")
than a standard S700 Carling series switch (1 3/16"), so it's hitting a fuselage
cross cage tube before I can get my panel in place.
Is anyone aware of another 5amp switch breaker with similar profile to the S700
series switch that I could swap in place of the Tyco?
I could move the switch breaker to another location up on the far right side of
the panel where my two alternator breakers are....but I'd like to keep the switches
together if I can.
Thanks for any ideas.
Howard
