--- Quote from: KungFuJosh on September 14, 2024, 10:08:34 pm ---Mike, help! I built your cool SMT fixture, but I don't have a 3D printer, and the rubber clamp tip doesn't work at all for 805 parts. What do you suggest I use instead to secure the SMT parts to the fixture? Thanks, Josh --- End quote --- Got a matching bolt, thread tap and a drill ? Turn a piece of nylon shaft to a blunt point, drill and tap it and fit it to a suitable bolt/threaded shaft.....or some combination of this. |

The way the clamp drops down is a little awkward too, so I'm not sure the nylon bolt idea will work great either. |

It looks like a nutcracker. ;) And that should have some advantage over the “normal” SMD fixtures? |

It doesn't firmly press well, and tends to move the DUT off the traces. Then the DUT is stuck to the foot and needs to be pulled off. The traces need precision placement of the DUT, but the rubber foot has moved it in every attempted use. I can't do short correction because the 0Ω resistor fails to short the traces when the foot is applied. At best, I've had 2 of 4 traces shorted. Even using a piece of copper gets pushed out of the way. |
