| Desoldering tool.
Have you ever used a desoldering tool like this?
I have several of those in my workshop, but I never liked them at all.
With printed circuit boards, they easily damage the soldering islands.
Specially when restoring older electronics with those brown circuit boards,
this is often a problem. For free wired circuits they are no
good, because when you release the spring, it shoots
agressively and damages 9 pins sockets easily. I have tried several
desoldering tools, expensive ones, with electric pumps.
They all have the same problem that they get stuck from particles, and
you need to re-clean them every time. Besides, they don't take
out the solder out of the PCB holes very well. They get stuck with larger
drops, and when cleaning, you get this poisonous dirt
on your table. Yikes! Wash your hands carefully. Forget
the expensive versions with electric pumps. They are only good for micro
electronics, and when you continiously clean them.
Some
months ago I was send this desoldering tool as a gift, by one of my material
suppliers, just to try it out. I was so pleased with it,
that I decided to offer it for sale here. It is a genious product,
that works without violence, and has enough heat capacity (40Watt)
to melt larger solder joints. It never gets stuck, no matter how
much solder you remove at one time! Vintage PCB's and tube sockets
are not damaged any more, and when you're done, this tool is easily
cleaned! You just hold it above a waste basket, and press it quickly
a few times, and all solder is removed. No need to take it apart,
and no dirt produced. When ordering, please mind there is only
the 230 Volt version available. Note this is old stock from around 2005 |
Solid Silver Solder. Large 100 gram
roll.
This
is not pure silver, but an alloy, and you can solder this just with a normal
solder iron. You do need the special flux with it that we sell also.
This is a liquid flux, also excellent for litz wires. Good
silver soldering takes practice, but it is easy to learn. For
best results take a lot of flux, and add more flux when you re-solder.
Remember that with silver solder, the flux will start to function
when it is burned dark brown, by the heat of the soldering iron.
This is what is different with normal solder. So take a higher temperature,
if it will not flow good. The burned flux can be removed later with
alcohol, or other solvents like acetone or nitro. It wil solve in
almost anything, just not in water. Use a small, hard brush to remove
the flux. Silver soldered joints will be bright and shiny, and look
much better than normal solder. They are mechanically stronger, because
the silver solder is much harder than normal solder. It is
highly recommended for soldering silver wires, which are just mounted "loose" in speaker cabinetts. Silver conductor wires are harder material
than copper, and this means the mechanical load on the solder joint
is much higher than you expect. After some years, bad contacts
may come when thick (>1mm) silver conductors are soldered with too soft
solder. This is not recommended. So, use silver solder for
silver wires thicker than 1mm. Also, this silver solder will not
give "cold" soldering joints so easily.
