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'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.

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 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

After wash cycle, some of the inductors are open (broken wire). Resistance across the two ends should be below 4 ohms (normal) however on broken wire shows above 200 ohms. I am wondering if anyone else has seen this problem. We are using High-Reliabi

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

Anyone placing micro,mini,midi spring inductors (as can be seen on http://www.coilcraft.com) with an FV7100? I can get the little suckers to "test" all day long, but soon as I go into production mode the vision system rejects around 20%. I've tried c

Thanks Rob. We've been in contact with Coilcraft, but haven't gotten anywhere, yet. We'll check out the other coils. We started using Coilcraft because of their high Q.
