Tin is an excellent solvent. So, whether using lead-free or leaded solder, your wire will neck to one degree or another if the material of the wire dissolves in the metal of the solder.

What you have run up against is the unfortunate consequence of the transition period from Sn-Pb to Pb-free. In the past 2-3 years there have been several studies highlighting the differences in reliability between mixed metal systems, Sn/Pb, and SAC

Well, it finally happened. A machine Operator did not follow our bar code process and "grabbed a tube of solder paste" and guess what. Built 250 assemblies with LF paste when it should have been Tin/Lead!!!! SOLDER PASTE SUPPLIERS: can you make t

Copper wire will become thinner when dipped in tin/lead or lead free solder. The copper is disolved off of the bulk wire. This is one reason rework on solder pots must be restricted. Eventually, after repeated cycles you will have smaller and sma

Similar to my response to your previous posting on this topic dated 5/8/01, things to try are: 1 Contact your non-supplier [Streckfuss] using the contact points at http://www.streckfuss.com/wave_soldering.htm, obtain source drawings for components o

Our two component suppliers use 99.5Sn/0.5Cu and 97Sn/3Ag solder (respectively) for tinning their leads. We use 98.9Sn/.66Cu/.33Ag solder in our wave solder machine. Is there any significant advantage to either tinning process regarding solderabili

We did a tin bath on ours but it was provided for free by Nihon Superior so that is a no-brainer. It was better than taking a risk of having to dump the pot. If you cant get a free tin bath, then you should probably go ahead and fill it half way or s

Hi, Bill, Lead-free solder and paste manufacturers will be a great resource for you during the transition; they've tested their products extensively, and their application groups have been able to help me through the biggest changes. There are a fe
