I don't know why I'm doing this. Probably this board has other issues and this is all for nothing.
And yet, here I am, soldering INSIDE a chip.
Tomorrow or Monday I'll tackle the other 8 missing pins. Too tired now.

@hkz our lab has several people who do just this sort of thing with prototype hardware @magnetic_tape yup, but I'll be damned if I can find where I put the enameled wire of the small enough diameter... Only found the larger ones. @hkz @magnetic_tape It's inside that appliance whose disappearance nobody will notice if you hide the rest of the body well enough. @hkz Do you have access to a CSAM? I worry that chip may have delamination inside that has ripped off ball bonds in places you canโt see. That aside, I am really impressed that you are soldering to the lead frame. Wow. Thatโs above and beyond for sure. @trollball eh, there is almost no info on that chip around, no replacements either unless they're sourced for other boards. So, it's probably going to be wasted time except for the exercise @hkz this like like a fun activity! @hkz oh wow. That's a repair for a good cause though. @haihappen I lived my whole life with the strong suspect that one of my ancestors pissed on the wrong totem pole once... @hkz What happened to the missing pins? Were they mechanically damaged? Or were the pins destroyed by a leaking NiCd battery? @hkz Yeah that is also a good reason especially for consumer device near to customers. But this sounds also you got a good chance to fix it if there a no further destroyed pins or visa. |
@hkz It's for the love of old technology.
