As some of you know I have been connecting a
couple of wires to some calculators,
a parallel switch to the ='s button switch.
Things worked fine with the conductive ink
printed circuits, a simple matter of taping a
bared wire across the specific part of the printed circuit.
Now a regular printed circuit...copper etched
circuit...it doesn't seem to work, of course I
scraped the protective coating off down to bare
shiny copper, the line is about .030 wide, Put 2
small holes on each side of the line about like this ..
the lead wire is on the back with the
bare end poked thru one hole and looped over
the bar and poked back into the other hole just
putting a little square of tape doesn't make
good contact.
I notice that where a bridge across some bus
bars is require they just paint it on with some
type of conductive black paint...can you buy
this stuff somewhere or should I learn how to
solder printed circuits?
My couple of attempts at soldering printed circuits
were a dismal failure, I use the right
type of solder and flux from RatShak but I
suspect that having a cheap pencil iron with
uncontrolled heat probably goofed me up
....thinking putting a slight dab of flux on the
iron and as soon as it starts to smoke...
unplug it and solder a joint before it cools off?
Okay guys...can you help?
Thanks a lot!
