'[EE] Finer syringe tips for soldering paste'
2006\02\07@212711 by Victor Windreader

I bought some solder paste in a syringe with a tip and did some
SMT work but the tip dispensed waaaaay to much paste. I ended up
placing paste dots on the pads using a pin. This worked OK but was
tedious. Where can I find syringe paste with a finer tip?

Any enlightenment will be appreciated.

You don't. But you can go down to your local pharmacy and buy some insulin
syringes, but your mileage may vary.

Finer tip (needle) does not work too well.  The paste clogs the tip and, if you
apply more pressure, just the flux comes through.  I ended up going back to the
original syringe.  I am just trying to put small dots of the paste.
Hope this helps.  Anyone knows a way to make inexpensive stencils?

Sergey,

Yes. But contact me privately as I don't want to overload/piss-off the kind
organization that produces them.

Making a screen is only half-the-challenge, you'll still need to orient it
strongly/well.

We bought a bunch from Mcmaster-Carr (http://www.mcmaster.com/).  They
have lots.

gauge        opening         p/n                price($US)
14        0.063"         6699A1          $14.89
16        0.048"         6699A2            14.78
18        0.034"         6699A3            14.67
20        0.024"         6699A4            14.56
22        0.017"         6699A5            14.44
24        0.013"         6699A6            14.33

Above are bags of 50, fit luer lock syringes (which is what Kester paste
comes in).  You can snip the tip off to make a larger opening if the one
you get is too small.  I can't remember the size but think it was the
.034" one from the above list.

>> Where can I find syringe paste with a finer tip?

If it's a "standard" syringe, there should be lots of sources of
both blunt "needles" (from electronics and hobbyist sources, like:
http://shop1.outpost.com/product/1560660?site=sr:SEARCH:MAIN_RSLT_PG)
and sharp needles (from medical and veterinary sources, or even ask
your doctor next time you have a checkup.)

Thank you for the suggestion. I would have never thought of McMaster
Carr. I just ordered what I needed.

There are places online that will cut you a stencil from mylar for $30.

I can look up the link if anyone's interested.  LOT easier than trying to
use a syringe.

Sounds like the sort of thing to get one of those advertising sign places to
do - except the stuff they use is sticky on one side.

Be interested in having a look anyway.
TIA

I got curious and Googled for it. /Lots/ of places seem to make this kind
of thing. Something like 'mylar laser cut stencil solder' should get you
close.

These guys describe their small scale production in pretty good detail:

OK, thanks for that. I think I will have to investigate this further.
