Could this be used for CPU (or some other truckload-of-pins chip) "reballing"? Does it do well under a bolted-on radiator / pressure plate?
For instance, many old Playstation 3 systems go faulty because of the poor quality solder on the CPU/GPU that tends to crack over time. Being a normie, it's really hard to fix something like that at home. But this tape seems like it could save the day.

The datasheet[1] says the minimum gap between conductors is 0.4mm, so based on that it should work for 0.5/0.65mm BGA. Also would clearly affect the speed you can run things at due to introducing parasitics. But would certainly be fun to try.

- teraflop 5y agoGetting the chip lined up accurately enough might be a bit trickier. With soldering, you can normally rely on the solder's surface tension to pull the pads into alignment.
