We use SnPb paste and bar with leaded and non-leaded component finishes. The predominant finish on components we use is Tin, there are a few NiPdAu. We've had no problems with the component finishes used in the SnPb process.

Today is more complicate to find components with lead than with "lead free", and the, I think that you have very feww lead components. And, if don�t work on exceptionals companies, you MUST use LEAD FREE PASTE. In one case, or in the opposite, the re

Leaded paste, is what we use if the process or product requires it.

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

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 temperature spec are people using in the industry to make sure an electronic component is SMT reflow compatible ? Ex. I have some parts that I want to possibly process as Pin in Paste but am not sure what temperature ratings the plastic will m

The lowest peak temp. I've had the pleasure of working with is 240°C +/- 5°C. I can't imagine a manufacturer going much below that and still saying it's lead-free compatible. It would be interesting to know just how much TAL plays into the affect
