We have been using SN100C in our RPS Rhythm selective solder machine since we bought it in 2008 with good success. No issues with the solder pot. We are setting the pot temperature to 300C.

Rob Just wondering - have you made analysis of your solder alloy on a regular basis? We are using SAC305 but stainless steel parts (e.g. a nut or a washer) dissolve quite quickly.

Hi Stivais, Yes, we analyse once a week in 4 pot locations, in addition one of our customers also takes an audit sample once a month and XRF's it. So far no spikes in the stainless pot that are not found in the titanium pot. Thanks, Rob.

I decided to replace the psu with three din supplies since it was a repeatable issue with the 5v rail. Machine is back in operation now with no signs of problems.

I'm looking for a Zevatech PM560 Technical Manual. There was an earlier thread now locked which mentioned someone looking and someone else supplying one. I was wondering if I could get a copy. Thanks

It shouldn't be any issue if you measure the top reflow settings using bottom profile board & the results are OK. To common the reflow profile, both bottom & top profile measurement are taken & analyzed. This, too, can be applied, even for differen

If you prefer to use same profile - it will be fine most of the time. There are several things to consider. 1. Is there part on second side that cannot withstand temperatures from first side? 2. If there is a high mass component on first side, that

We run double sided boards that have large SMT electrolytic caps on the top side using the same profile for both sides. The trick is to do the bottom side first, then the top side. That way you do not need to glue down the large caps.

That is why we don't care if it is Top or Bottom. We call them first (process) side and second (process) side. Often you will have tall and heavy parts on both sides, so you will have to glue them.
