I've soldered 0.4mm many times but not with individual wires like that, always onto a PCB. It needs a very steady hand, and lots of patience to do that type of work above. Maybe I have been spoiled by just making a prototype board in the PC and getting it sent off for manufacture. Takes about a week from start to getting a bare board ready for soldering. I wonder how long it took to make that board above manually? Must be at least a week of work there, maybe more.

A cardboard PCB. Cool I've not seen that before. Very nice ... and light.

I wonder how this type of prototyping could be adapted to BGA? I think we reach a limit once the realm of pins disappears and the realm of balls takes over.

The most difficult component I've ever encountered is a 0.4mm pitch BGA. Even routing the PCB is tricky so I can imagine that doing it manually with individual wires would be exceedingly awkward (to say the least).

so far so more difficult for hobby Smile never through away used parts - the only thing can help us. not so far ago failed to buy AT29FXXX in DIP in the shop - only SOIC. thanks to dead PCs - i have some from them Smile

I thought of this thread when I read this: http://www.8008chron.com/ It looks cool, but I don't know enough to say any more than that.
