With the shape of the pins curved under the chip, laying the DRAM on a PCB wouldn’t be sufficient instead of using a socket for testing ? Applying a little pressure on top maybe…

It's a good thought, but I don't think the legs are ever going to be perfectly straight enough for that to work reliably.

Thought I would do another video. "A typical Monday with exxos". Basically because I just know for a fact that every Monday in particular things are not going to go well :roll:

Aim of today - Finish desoldering the STM DRAM chips.
What actually occurred - lots of stuff breaking and there was even a terrible fire :fire: :fire: :fire: :hide:

:lol: Yeah," one of those weeks" is currently at month seven I think. There's always something going on in the background. Like this week, one of the neighbours came round saying we have got expanding damp patch on side of our house.. Been looking into that this week.. One thing after another all the time..
