re: tweezers and stylus

re: tweezers and stylus

2006-08-29 by Mark Mickelsen

Hi,



I'm getting ready for my first attempt soldering some SMD's and I realize
that I need a better pair of tweezers to place them. I would like a pair of
those long, thin tweezers that taper down to actual points. It would also
be nice to have a long, thin pointed stylus for holding things in place.
Can anyone help me by telling where to look for these kinds of tools?



Thanks in advance,

Mark

Any of the main electronics suppliers like Farnell and RS will have them.

Medical instrument supplies or sometimes lab supplies have a wide variety.
My tool shop also has a good one.

I found the bent ones most useful, because you can turn them over and do
this:

I like the larger tweezers better, with a large handle but a fine tip. The
smaller ones seem more difficult to hold. The better quality ones seem to
have a pin and a hole to help align them, like just visible in this
picture:

I also like reversed tweezers a lot. They work great for SMD soldering:

This page also shows the rather high prices ;-)

Look under Tweezers at: https://webvia.techni-tool.com/VIA/index.jsp

Lots of other people have suggested where
to buy them - so I won't do that.

I Will say you can just use a ball of
blu-tack in place of the tweezers AND the
stylus. Get a small ball of it. Roll it
around a bit so one end comes to a point.

That point can pick up SMD parts from
above and hold them down whilst soldering.

Dirt cheap option.

And although it has the disadvantage of
contaminating the component by touching it
with blu-tack. It has the great advantage
that you can always find some blu-tack and
you can't always find/get-hold-of your
fancy vacuum pick up tool or tweezers.

... in your wife's sewing box!

a pair of wool needles soldered to a common tweezer is stiff and strong. align
the points very carefully. some grinding may be needed.
a long sharp sewing needle stuck backwards into a large toothpick makes
miracles. common pins are not stiff, sharp and long enough.

I also made a sort of weighted tripod with a needle as the third foot for
holding in place those SMD for hand soldering, something like

i_____o________V (shown upside down).

where O is the weight, a couple ounces(half pound?). the two feet V must be
quite spread and heavy to avoid tumbling over. I made them very smooth so they
don't stick on the surface behind the PCB under work. height something more
than the needle used (1.5"), so the needle stays vertical on top of the SMD
under work.
total some 8" or more long.

needles are nice because they are very stiff and almost don't obstruct the
view.

oh i didn't mean to suggest it would be a good idea to buy those tweezers
there.
Just showing the types they make. cheaper models will do.

Certainly does! The last pair I bought came from a tool stall at the Royal
Welsh (agricultural) show for a couple of quid. He had loads and all sorts
of small probe like tools as well - looked at bit like a dentists tool kit
but I don't think so somehow.
