Sure, to be a true lead free enviroment all components need to be lead free or fall within the specifications of lead free as defined by the RoHS Directive. What I am doing is starting stage 1 of our journey. Layed out it looks some thing like this.

If it is instructed to ship lead free product to customer, then low temp lead free solder paste can be considered. For example, Viromet solder paste from Singapore Asahi (peak temp is between 220 to 225 degree C).

what type of solder paste I should use if Rohs and non rohs component mount on same board

Good afternoon, You have to use lead paste since none-RoHS components won�t withstand elevated temperatures. Solder paste manufacturers offer a lot of transitional pastes designed specially for mixed process. Ask your paste supplier for transitional

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
