| 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. |
