I looked breafly at this alloy. My concern was that I had already implemented a SAC 305 alloy at SMT. So any of my mixed technology projects would one alloy (SAC 305) on one side (topside) and a different alloy (SN100C) on the bottomside. Most articl

Contact your paste supplier and see what they say. My information on SAC 305 FROM MY SUPPLIER was - "The cool down rate is not as critical for Pb-free solder joints, as it was for SnPb. The grain sizes do not differ is size in the Pb-free bulk solde

It is one of our pastes...Almit LFM48 W TM-HP, a high reliability no clean solder paste based on SAC305 with a size 4 powder. It's a paste that works so well we have thousands of users of it worldwide. Why are you using SN100C alloy paste ? I imagin

Today, I have just finished evaluating Kester's EM907 (SAC305)lead free solder paste and found that for our applications it performs as expected. End result that I am encouraged with the results that we got. The equipment that I used: An SMT2020 to

You can measure temperatures any place that you would like, but the issue is the temperature of the solder. We've seen solder temperatures that vary from lead to lead on the same component. Why don't you want to measure the temperature of your so

We're used to placing the theromcouple on the solder joint and securing it with thermally-conductive UV adhesive. It's quick & easy to apply, and I've only seen a couple degrees difference from high-temp solder technique. Thoughts?

You can, and for small parts you probably won't see much difference between body temp. and lead temp. For QFPs or PLCCs there will be a much greater delta, though. I'd be more concerned with the small surface area you're making contact on (spherica

Reflow profiles are based on the product and materials you are soldering. You need profiling software and a data logger.

I wouldn't think so, A thermocouple can be attached to the lead that is being soldered. Russ
