| Feb 3 at 17:29 | comment | added | Chris H | @MarkMorganLloyd yes, I was just adding a non-soldered failure mode (mine, BTW) will be screwed together for thermal contact, so plenty of pressure, and in a fairly clean lab. It's inspired by the interlock circuit on some laser systems I've used | |
| Feb 3 at 16:59 | comment | added | Mark Morgan Lloyd | @ChrisH I know, they /might/. But equally they might be relying on the wight of something paced in a charging cradle or on a charging base, where not only is the pressure erratic but potentially-contaminated contacts are placed together without a wiping action: both are harbingers of premature failure. | |
| Feb 3 at 15:33 | comment | added | Chris H | @MarkMorganLloyd when used other than on PCBs, they may be held in place by grubscrews. Overtightening is an issue then (something I'll have to beware of in a few weeks, assembling a test fixture for laser diodes, into which I designed a 4-pogo-pin connection) | |
| Feb 3 at 7:45 | comment | added | Mark Morgan Lloyd | @MOSFET I'd add that regrettably, they break: particularly when used for recharging etc. rather than for occasional test or programming purposes. I don't know whether this is in any way due to their being soldered in (spring is exposed to soldering temperature) rather than socketed. | |

| Feb 2 at 14:30 | comment | added | Transistor | Maybe you can explain how you think pogo pins are supposed to function so we can see where your misconception lies? Hit the edit link below your question ... | |
| Feb 2 at 14:20 | comment | added | brhans | "apply a significant force external (against the spring,)" ... well, yes - that's exactly what happens. The pin gets pressed against another contact surface, and they're held together by some other mechanical means, causing the spring to compress. | |
| Feb 2 at 14:12 | comment | added | MOSFET | If they're not broken, they don't retain their position. | |
