Hi All,

I need someone with high level soldering skills to solder a component
onto a small circuit board - I think special temperature controlled
soldering equipment needs to be used to do this (its way beyond my
expertise).

Does anyone know how I can find a local workshop or perhaps individual
that could do this work in the London W4 area? (I'm afraid its only a
small job)

Thanks, George

Bit more detail would help... such as what sort of component? Surface mount
or through hole? Multi-layer board?

Even reasonably dense surface mount can be done by hand if you are careful
and use a small iron/tip...

Find a competent and willing radio amateur over on UK.radio.amateur to
help you out perhaps?

Thanks John,
Its actually a screen cable for an old PDA (the screen ribbon cable is
soldered onto the connector at the bottom of the screen)- I have tried
to do the job myself and already succeeded at making a mess of it -
I'll post a photo link to show the problem.

Thanks, G

If it has a fair bit of copper content to it, then it likely needs more
heat.

Does mean you are neither competent, or willing then?

It could equally mean that I could not at the moment spare the time.

-but I might be willing/able to help if the OP indicated roughly where
he lives.

Yes, it's a long way from you. Couldn't resist the dig, seeing your call
sign.

No! I am about as far as way as you are. Preston.

Thanks for the replies - yes I am in London W4!

I tried using a battery powered soldering iron I got from Maplins but
it wasn't powerful enough, but an ordinary one was too hot I think.

Please take a look at the photos I've posted in the attached link:-

One of those "instant heat" ones with a split tip? If so don't use it
on electronic circuits, it applies a voltage across the two sides of the
tip, which can damage the circuitry.

No, not the short-out heat tip type - I just think that it was too
cool and the ordinary one I had too hot, combined with my lack of
skill it ended in disaster.

Temperature is everything, especially with lead free solders which require a
higher temperature to melt and flow. Too hot and you destroy the plastic
and any adhesion between copper and substrate.

I can only suggest you look for "electronic assembly" in your local
directories and pay a visit. Anyone with half an eye and who is competent
with a soldering iron should be able to do this for you. If you were local
I would say pop in, as it would only take 10 minutes.

That has an absolute minimum of copper mass and just needs a good, fine
tipped soldering iron and the right knack.
