Anyone who has worked with pcb design knows this is garbage.
This looks like what happens the first time you send off a design to a pcb house and get back a pile of unusable laughable crap.
That's what I'm guessing happened here...one of their so called engineers learning to use Eagle for the first time and made a big mistake.
That's a plausible explanation. I always said I thought the PCBs looked really weird, and certainly using microvias for all the pads would certainly be a strange choice, no doubt.
I almost wonder if the boards are actually
upside down , and the visible traces are just for grounding the chips - which would mean 1 via underneath the solder pad, and the lines that look like pads for the chips are actually just silkscreened markings to show where the're supposed to go. They look like they're the same color as the other white markings, as far as I can tell - it's pretty hard to see.
But anyway the whole "the boards are bad that proves they're scammers!!" thing makes zero sense. Why would scammers create boards with no traces when they have $700k in IPO money to spend. You can get a PCB created in 24 hours, with any design you want, including
full netlist testing to make sure all the connections on every board work fine. It would be expensive, but it's certainly something that could be done.
Some people have been theorizing that they're deliberately crashing the price in order to buy up more cheap shares to increase their stakes.
Whatever is going on they are behaving in a really unprofessional way, IMO.
Someone else mentioned....as a minimum you need decoupling caps close to the power/ground inputs on any chips...as close as possible. Usually I would put them tight to the chip, within 10mm is a general rule. So they decided to put those caps on the backside? Strangest design ever.
If the visible pads for the devices are for the decoupling capacitor, then they're only about 3-5mm away from the chips, which are only 10mm in width in total. I'm assuming that's what those pads are for, and the visible traces are for either the input or output power.
Or they could simply be not working.
Didn't they skip one testing step to get the chips faster IIRC?
No, they actually went pretty slowly. They ordered a test run of about 2k chips, but were going to wait until they actually got those chips and got them working before they ordered a second run.
