Thanks for your promt reply It was very usefull Eyal

Thanks Pete yes we usu ROHS solder paste in our process. I agree that this termination is more suitable for adhsive bonding rather than soldering. We'll try changing the termination type as you recommended. Eyal G

We've seen the exact same problem. The solder joints had negative wetting angles and x-sections show that the PdAg termination dissolved into the solder. We no longer allow PdAg terminations.

We are facing low quality due to soldering opens with coilcraft inductors 0402CS-2N7XGLW. The termination used is(suffix L =RoHS compliant silver-palladium-platinum-glass frit. Did anyone had this problem in the past? Can we do better using T = RoH

We have experienced the same problem with Pd/AG and P/Ag terminations on precision resistive parts. The problem is dissolution of the termination metallisation into the bulk solder. This is exacerbated by the higher thermal profiles required for RoHS

No problem. If you get no joy you're going to have to change the footprint to a 1206 or 1210. Murata have a range of high Q value inductors (50-60) & from memory Toko used to be pretty hot too. The terminations on the coilcraft part are listed a

We have been using Coilcraft 1008CS inductors for several years. We have had problems with them turning green when we use lead-free solder paste. We have tried several solder pastes (water soluble and no-clean)from different manufacturers, but the

I have some large ROHS SMT inductors that are moving during the reflow process. I have tried adding extra solder, gluing and doing both. I don't know what else to try, any suggestions?

i mean that the parts that we have here is ROHS compliant(pb free)but the process that we have(the type of solder paste & the surface finish of the board has pb in its mixture) this is not the cause of problem ?

I have a problem with a Murata cap chip type resonator(ROHS). After the reflow process, the soldering joints flow to one side of the component. I did not have this problem with the leaded component. Did someone have a solution for this problem?
