Hi Everyone,

A little while ago, I asked for advise regarding a tombstoning issue with a MELF. I received some replies and they all indicated that the pads are probably too large. Now, I would like to run an experiment to prove that out before changing the artwork on the board. I asked my board fabricator if they could rework some boards by adding soldermask to half the pad but I was told that the mask wouldn't adhere over the Immersion Silver finish on the pad. Does anyone have a suggestion that I could try?

Thank you,
