Here's some shots of a more recent project
where I have refined my relay mounting a bit more. |
(1) I have added 4 lugs around the relay
socket lugs so that I have better points to solder
external wires to. Wires that lead to tube
sockets, pots, etc are soldered to these extra
lugs. It's much easier and better this way, it can
be very difficult to solder to the lugs under the
relay socket. Note that these extra lugs are
jumpered under the board with short pieces of buss
wire.
Note how I have carefully soldered shut the last
two holes on the relay socket. The relay does not
fit into these holes but the lugs underneath are
used via the jumpers. |
(2) Here's a good close up of how I solder a
jumper on the relay socket. The lugs to the left
of the short pins have a flange on the top of them
that sticks out a little too close to the short
pins. It is very easy to mistakenly solder this
flange to the short pins. I trim the flange off
the top of the two lugs left of the jumpered lugs.
See the red line in the image. Next I very
carefully solder a solder blob across the two
short pins and the lugs on the right end of the
relay socket. You need a very sharp soldering iron
tip and not very much solder to do this. It takes
some soldering skills to get this done properly
without soldering across the red trim gap.
Note how I have carefully soldered shut the last
two holes on the relay socket. The relay does not
fit into these holes but the lugs underneath are
used via the jumpers. |
(3) The back side of the relay socket. The
yellow rectangle in the photo is where the actual
relay socket sits, the lugs outside the rectangle
are attachment points. I have installed the 1n4001
diode and the jumper between pins 3 and 5 on the
back of the socket. If you compare this picture
with the front side picture, you can see where the
bare jumper wires go. They go to the four extra
lugs I added for attaching wires and they also go
to other lugs that are direct attachment point
with no external wires.
Cut the relay socket pins flush with the back of
the board and then solder them to the lugs. Note
that the relay socket pins are only soldered on
the rear of the board.
