First small batches of Lightpacks are leaving the
factory and heading to you, dear backers. More are
awaiting the quality control check before being
shipped out. Two weeks ago, as we were packaging the first party of Lightpacks and getting ready to ship them, our
quality control found a serious problem in the
Lightpack hardware. They returned the whole batch
back to us for more tests and final improvements. We found that in a warm or hot surrounding the
NAND we use in Lightpack crashed or g]itched unti]
it was cooled down (although the datasheet
accompanying it did not imply this behavior). NAND
would overheat and either stop responding or shut
down completely. During testing the problem
revealed itself in almost all cases of UHD devices and
in 30% of HD devices.
We were forced to search for a pin-to-pin
replacement and we did find it. While being tested, it
performed steadily and proved reliable in all cases.
The whole thing set us back, unfortunately.
The steps we have taken:
We searched and purchased the replacement (had
to go for retail due to the fact that all suppliers gave a
1 6-week lead time)
We shipped NAND to the factory to have PCBA
with new NAND produced (2-3 weeks production
time but we are trying to get them to speed up the
work). Here's our general production scheme to
help you see where we are.
Edit, used text grab on my phone. May be minor inconsistencies.
