63/37 vs 65/35 solder

Electronics Forum | Tue Jul 27 09:28:34 EDT 1999 | Bill Bannister

We are currently using a 65/35 solder for our wave process but are considering switching to a 63/37 for a substantial cost savings. No one here seems to know why we everused a 65/35 formulation in the first place. I understand 63/37 to be pretty much

In testing 63/37 SnPb NC paste I have seen HUGE differences in performance. Have you tried a different paste? I prefer AIM (NC257-2), they have performed well in each round of testing. My observations regarding mixing old and new paste: The paste ha

We are having a lot of tomb stoning with this no clean solder paste. It's limited to larger, complex boards, affecting 0603 ferrite beads, capacitors and SOT23s. It was suggested that paste removed from a stencil should not be put back in it's origin

It's bad practice to remix used solder paste with new solder paste in the jar. Further, some would argue that it's bad practice to reuse solder paste period. If economics force you to reuse solder paste, store it for reuse in an empty jar. When rea

Thank very much for the feedback. I was asked why mixing the paste was not a good idea. Could you provide the answer please? It's always better to hear from an outside expert:) The SOT23 - some of them have actually flipped upside down ; plus we hav

On mixing paste: There could be a lot of hand wringing about the need to minimize solvent evaporation, flux separation, and chemical activity. [True alarmists will throw in oxidation of the alloy.] But I think the real concern is a change in viscosit

Paste control is a subject that has a lot of unfounded claims surrounding it. What is the difference in having a "working paste jar" and a "new paste jar" Either way new and old are getting mixed at some point. We just don't buy onto the whole thing
