Switching to SN100C in wave solder machine | 23 November, 2016

Hello,

I am new to this forum, and was hoping to get some advice/information from those of you that have switched your wave soldering machine to SN100C.

I have read some old threads about people having great success with SN100C. My question is- what are your thoughts now after using it for many years? How quickly did the SN100C attack your stainless pots? Any insight as we begin this transition to SN100C in our wave soldering application?

TIA

Never used stainless pots as when we converted to lead free we changed all the pots to titanium.

Been using SN100C for many years now, very good results, also use it in reel form in our selective solder machines with great results.

Bear in mind the higher reflow temperature of this compared to other alloys though.

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.

Any lead free will eat a leaded designed wave soldering machine. But SN100c will eat it the slowest, our soldering tips used to only last 3 months with SAC305 when we changed to SN100c solder wire we are having around 9 months tip life.

Our wave solder pot wall is vitreous enamel coated and im not sure about the pumps or nozzles but they haven't dissolved yet.

you could however do the same vitreous enamel coated on the wall and have the pot elements titanium sputtered.

We've run for about 2 years with SN100C on a Stainless pot, and all looking OK at the moment - we have just drained the pot and swapped to a similar solder (customer request)so we had a good look as we were interested to see what was happening. To be fair I was a little dissapointed as I've spent a lot on titanium pots over the years.

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.
