material for your BITX transceiver construction
Hi
Can I also
suggest that where the components are to be placed that the PCB pad is
tinned?and where earth connections are to
be made that area too is tinned, as it ensures a good joint
and?the joint is quicker
too!!?
?
I think the sort of bush
mentioned has brass wire bristles and used for cleaning suede shoes
!!
Hi
PC Board material that is stored
for some time usually takes on a layer of oxidation that hinders soldering
components to its surface.? In the past I have routinely used sandpaper
to remove this oxidation and prepare the surface for my "ugly construction"
projects.? Now I think I might have found a better way to prepare the
surface.? I tried a small wire brush and found that it not only removes
surface oxidation, it also leaves a much more polished surface and requires
less effort.? The wire brush was purchased at a local hobby store for
about $1 US, see the picture below.? If you have a small wire brush you
might try it and see if it works for you.
