What are Resins, Solvents, Activators, and Thickening Agents in Solder Paste and what are their helpful and harmful effects? AND What are the purposes/properties and effects of Sn(Tin), Pb(Lead), Ag(Silver), Bi(Bismuth), In(Indium), Cu(Copper), Ni(

Evalution on solder paste and spray flux

Well first off I wouldn't evaluate paste for a wave process. I would use solder bar instead. Flux - top side fillets and no shorting on the solder side, does it clean well after processing if using water soluble flux. How wide is the process win

Ask Brain Toleno at "circuitsassembly.com/blog" He's a smart guy and works as team lead at Henkel Loctite. Just don't take him out for drinks.

SOT23s and paste + glue

Electronics Forum | Mon Dec 22 11:09:21 EST 2008 | mfcat

We changed paste manufacturers rather recently and are now seeing SOT23s falling off after wave solder. These parts have a dual process... we stencil print paste, apply glue, populate then reflow. Only SOT23s fall off, chips are fine. We do not be

Maybe this piece of information will help. In China (just returned from visit) there are many factories that are using a dual temperature process using SAC305 or Sn100C and 42/58. Apparently this allows them to run their through hole parts through re

Ryan ... "As for bismuth-based lead-free alloys, a lower melting temperature than that of tin-lead is offered together with a cost similar to that of tin [in the area of $3/lb]. Unfortunately, bismuth in soldering alloys tends to create embrittlemen

So how does this (lead free paste Sn42/Bi58) solder compare with the Sn-Ag-Cu (Tin-Silver-Copper) combination which does not flow as well (in the oven), needs higher oven temperature, (that can be adjusted by reducing the oven chain speed) and cost m

Multiple process and rework thermal cycles are brutal on boards and components. Improving reliability of products through reducing thermal stress ends-up being a major driver to the interest in lower MP LF solders. Binary LF solders require the addit
