Teardown Tuesday
Dave's Samson C01U USB Microphone got caught up in the flood, let's take a look inside.

Because I worked in electronic manufacturing for many years, wouldn't that duel footprint of those surface mount chips also be used for long term repair of the board for say warranty or RMA repair , not just for the initial manufacturing process ?

Can be, yes.

Nice to see the insides of such a mic. Thanks Dave.
I'm also impressed by the time taken from the shoot to upload....
To those interested - I was at the EEVblog lab this afternoon and left at about 4pm at which time Dave was just setting up his camera and the mic, to do the shoot. A nice, efficient workflow.

The capsule is probably 50pF to 60pF of capacitance, so I suspect the gate resistor is 510M and not 10M because the lower value would lose some of the low end response due to high pass filtering by the C-R on the jfet input. It is not uncommon to see 1G resistors in professional condenser microphones.

Were you able to do any kind of insurance claim on the damaged hardware, and will you be installing some kind of rain cover or retractable awning for that room in case there is another heavy rain storm?
