Has anyone had issues with Renco inductors failing. The component I'm having problems with is a 330uH shielded power inductor. Out of 36 board failures, I have 17 that failed because this inductor failed. Most often they end up reading -1.34 uH.

I don't think it's a stencil issue. You have an identical inductor next to t=it, that's perfectly straight. You have a problem in that location. I've seen some inductors be affected by slight magnetic forces in the reflow oven. Try to rotate the boar

Thanks for the opinions! You're right, it can't be solved with a stencil. I have made investigation, the problems are related to the quality of the component land surface, one of the terminal is oxidized.

The last time I got corroded parts out of my wash was when my DI tanks were spent, and I was pretty much using straight tap water. Refreshing the DI tanks eliminated my issue. Hope this helps. cheers, ..rob

Thanks for the tip! The DI tanks are brand new. Water quality is pretty good. The filtering is also good and the instrument in the water recycler measures about 12MOhm resistivity. Cheers, Luciano.

Hi! I haven't found any info about that product. I can't even find it among Zestron products. Could you tell me where to find some info about it? Thanks!
