solder paste for smt functions

[tim gorman]

I've been using regular soldering equipment for smt stuff like SOIC chips.

I'm getting ready to move to even smaller stuff like LQPF packages and is
probably time to start using equipment designed for this.

What's the best place to get solder paste in small quantities (I'm not doing
production work just prototyping work as part of my ham radio hobby)?

Wassco (www.wassco.com) sells 35g syringes of paste for about 1/3 of
what Digikey wants.

I went down to a local PCB assembly shop and got a free syringe of
expired solderpaste and it worked fine. I think for prototyping the
specs can be a lot less than if you are doing production work.

Check with Topline, see if they will be willing to send you a sample (see
link on this page)

Rob,

Thanks for the recommendation. They are just what I was looking for.
Reasonable price too.

If by equipment you mean stencil and solder paste, than go ahead. If you
are going to syringe the soldepaste in pads you are going to make a mess. I
suggest 0.015" pitch solder (Digikey) fine tip and stereo microscope.

Tim,

You might also check out HMC Electronics (http://www.hmcelectronics.com)
and Techni-Tool (www.techni-tool.com). Their prices seem to be a little cheaper
than Wassco.
