You might try checking to see if the float switches are actually lifting up with the water level, I have seen them get stuck in the open position. Also check to see that the solenoid valve is actually sealing off (closed)

I am trying to find out what would be considered the minimum test via that would be considered reliable for Flying Probe testers. Specifically Javelin testers. Also what would the minimum annular ring need to be.

I am looking for any input on the linear stick feeder from Mydata. We currently use a vibe feeder and have a high number of miss picks/rejects on SO8 packages. Is the linear stick feeder worth the investment to upgrade from vibe?

Thanks Dave. Specifically, do you know what minimum conductor spacings are on 0.030" via holes - via-to-via?

I've had some luck with longer soak. Of course that was on a board with severe thermal mismatches so I don't know if it will help your problem or not.

have you try to change the stencil apertures to another figure like the one that look like a baseball home? I was having that problem and some solder beads and with that I was able to decrease the tombstones
