Finally! A Eutectic 63Sn/37Pb Solder Paste developed for PCB for R&D groups, engineers and technicians at work in labs or at the bench with new designs, prototypes or in rework and repair.

Our now famous, high quality, no-clean SPE-0012 ZephPaste™ solder paste is used in the most prestigious national labs and campuses from NASA and Fermi to Sandia and Harvard. Why?

Shiny, high-quality, reliable solder joints from a solder paste that exceeds all Bellcore Specifications and industry standards and with two decades of proven history! And our loyal customers still rave about our paste.

Six-Month Shelf Life! No Refrigeration Required! The SPE-0012 soldering paste is a eutectic 63Sn/37Pb formula, distinct from other pastes marketed today. Filled into convenient 10cc syringes (or barrels), it is a low residue, no-clean paste with a unique flux/sphere ratio perfected for the bench. And it has a 6-month shelf life without refrigeration. Buy one, try it out, become impressed. You owe this to yourself.

Premium Formulation 'Stays Put' on Pads:  With virtually homogeneous properties, the SPE-0012  paste "stays put" once dispensed to your pads...and with our remarkable Zero-Balling™ attribute during soldering. What great news for those using the classic, traditional PCB tin/lead 63Sn/37Pb or 60Sn/40Pb soldering alloys!

All Orders Ship From Factory "On Ice". Yes, ZephPaste™ has a 6-month shelf-life without refrigeration and we still ship each order to you packed "on ice" so you receive the freshest paste possible. The 6-months shelf-life begins once you receive your paste. How about that? And Zephyrtronics has no minimum orders!

Some History: Everyone knows that 60Sn/40Pb and 63Sn/37Pb eutectic solder alloys are classic and long favored in high volume PCB soldering for over 60 years on the production floor. So why was solder wire, not paste used at the electronic bench for prototyping, low-volume production, and rework? There are two reasons:

1.) Using paste with soldering irons was problematic, if not simply prohibitive (think of splattering bacon grease);

2.) Solder pastes used in high volume production processes have very short shelf lives due to the flux/sphere ratios needed for conveyor oven reflow systems and they require refrigeration. Remembering to "store" your solder paste at the bench or in your lab at the end of every day is.

Because solder joints made with solder paste are superior to those made with solder wire (especially with SMD's), Zephyrtronics developed a no-clean paste with a flux/sphere ratio to require no refrigeration and specifically targeted to the electronic bench. And our paste works perfectly with a non-contact hot air pencil and a preheated PCB. So easy. See the short and helpful "How to Use Solder Paste Video" below.

Production Quality Soldering at Your Bench!  Shiny solder replete with shiny fillets on the toes, heels and sides of the chip's lead and pad interface! Our proprietary SPE-0012 Solder Paste formulation is the result of years of research, extensive laboratory and field testing. Solder paste doesn't get better.
