tl:dr; EEG Dev Kit production completed. Electrodes almost finished. Orders shipping soon.
Manufacturing electronic products can be difficult.
Making 10 is easy – they can be done by hand. Making 10k is easy, everything is on reels direct from the supplier.
But making 100 or 300 or 1k is where the dragons be.
Big manufacturers don’t want small orders like this. Components are not sourced on reels so must be checked individually. Setup time and overhead fees are disproportionate. Everything is a PITA. This is what foc.us fights with.
But today’s story has a happy ending.
Our new PCBA factory is much bigger than the two we have used before:
They use the same pick and place machines:
But the quality control is WAY better as they x-ray every PCB one by one.
The EEG Dev Kit has nine BGA components so this step is crucial in identifying any possible problems.
This has resulted in the best yields we’ve ever seen – 99%!
The cost of EEG components is crazy high, so a yield of 1% (it’s actually less than 1%, I rounded up) is fantastic news for us.
Each Dev Kit includes three pcbs – main, sockets and electrodes. This is the sockets PCB exiting the oven.
All that remains to complete is the new EEG+ electrodes. They are nearly done and will be very soon.
We will be using this factory for all PCB work henceforth. If they can get 99% yield for EEG we expect 110% for Go Flow 😉
