The Preamble to the Constitution goes something like this:

We, the people, in order to make a more perfect termination...

Hi Mr. Parker,

Let me continue...

"We, the people of Electronics Manufacturing Industry, in order to make a more perfect termination and to be able to produce a reliable interconnect, do solemnly swear that from this day onwards we will be using solder paste for our Surface Mount Electronics Products.....

hahahaha....sorry...can't resist too.

Yins are bad, this guy's serious.

Generally, solder pastes are comprised of: 90% solder powder, 5% flux, 4% solvents, and 1% activators [by weight]. Where: * Solder powder, when reflowed, is a metal bonding agent that mechanically and electrically connects components to the board. * Flux is a chemically-active compound which, when heated, removes minor surface oxidation, minimizes oxidation of the basis metal, and promotes the formation of an intermetallic layer between solder and basis metal. * Solvents dissolve the flux and promote the cleaning action of the flux. * Activators get jiggy wit flux.

Having said that, every solder paste is different. Get more specific information from the solder paste MSDS at the manufacturers' [eg, kester, alpha, etc] sites.

There is a fairly extensive "terms and definitions" in the SMTnet Library.

ANSI/J-STD-005 "Requirements for Soldering Pastes" is the industry definition for these materials. You can find it at http://ipc.org

Dave-

I knew I could count on you to give the straight facts, as usual. All the more reason for me to practice a bit of license. Although, Dreamsniper said it better.

Activators get jiggy wit flux????? Dave, Could you define 'jiggy' for those of us who are among the culturally challenged?

You appear to spending too much time watching "Survivor" and too little down at Jimbo's

I'm not sure "Gettin' Jiggy Wit Flux" translates well. My first recollection of jiggy is ...

Will Smith "Gettin' Jiggy Wit It"
