solder paste for smt functions

Jan 04, 2005 6 Replies

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)?

sells 35g syringes of paste for about 1/3 of what Digikey wants.

Rob,

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

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.

cheers, Jamie

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

Their prices seem to be a little cheaper than Wassco.

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.
