Melf resistors roll off the pads

[Faringdon]

Hi,
We have been told not to use MELF resistors, MMA0204, MMB0207 because they  "roll about"...surely they get stuck in the solder paste and dont role?

surely they get stuck in the solder paste and dont role?

Would I agree? Yes, I would.

They don't role for me. I passed their role on to pulse rated chips or THTs.

If you're having problems, consider a glue step.  More of a wave than reflow thing though.

You can also have the stencil for paste designed witha  u shape, the inside of the U stops the parts from rolling and as the solder melts it still goes onto the part and rest of the pad

I have done that when using MELF components in the past and have not had any issues with them rolling off
