Since you offered: what is that trace called that is presumably electrically connected to the ceramic cap solder seal? I've wondered about its function, but have never been able to distill the prior sentence to the necessary power words.
Also, here is an extra ham-fisted attempt to get you to cover an off topic interest of mine: did you know that the Soundblaster DSP was an 8051? Cool, huh? pleasedoan8051deepdiveimbeggingyouplease. I'm aware of only one gate level analysis, with evidence of its existence on archive.org... tragically the spider never bothered with the actual zip file and the author is long gone.
Thanks for all the great reads, btw.
- kens 5y agoThe gold trace connects the metal lid to pin 1 (ground). This provides some electrical shielding. As for the 8051, I might look at it at some point, but I've got lots of other projects...
- sennight 5y agoha, and here I'd assumed there was some convoluted vacuum getter / ion pump at the root of it... nope, just didn't wanna screw about with the bond wires. Thanks.
