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

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).

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.

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

This is indeed yet another proof that under impulse of the RoHS directives all norms are flushed down the drain. Bean counters are slowly but surely taking over our industry because they no longer face resistance by form of standards. Even the basic

This shouldn't give you any issues as long as you don't have to be RoHS compliant.

Does anyone know if it possible to use Sn63/Pb37 paste on a board with Sn100 finish. Any thoughts on this will be greatly appreciated.

Careful on fine pitch QFPs. They will be your weakest joint if your parts are no-lead. And don't think you can simply run a no-lead profile either. Depending on your paste, you cannot simply run your profile in the no-lead temps and expect your fl
