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

Since the inductor is electro-magnetic, that means the device is composite of coil and ferrite metal. The inductor inside the reflow oven meets with blower motors which close to the inductor and generate magnetic field. With such conditions, Lawren

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?

Makes us wonder how well the connections on the component match with the pads on the board.

We did the firt 2 with no luck.

Makes us wonder how well the connections on the > component match with the pads on the board. The pads are actually larger than the leads on the part, but I think we may have figured it out. We believe the conveyor vibration is causing it. When we

Hello Everyone please help me identify the Inductor with specification as Inductor 26mh 0805. This is a very critical Inductor for my project, however, this small Inductor couldn't be found.
