Hi Randy,

i did sort out the main cause of most defectivity and it's unfortunately
a solderability on the i.MX6 CPU. Several boards are seen to have cold
solder balls underneath the BGA, so I'm having them rework the reflow
profiles and solder composition to improve yield.

Unfortunately that means I can't guarantee you would be able to get 20
anytime soon. We are running another order for 150 boards, but the lead
time for that is currently being worked out. The long pole in the tent
is the wifi card, the vendor is tracking a 13 week lead time to get the
material in, so after we wrap our shipping and integration time that
puts delivery out about 16 weeks (4 months!).

would you take boards without a wifi card, of course we'd reduce the
price accordingly?

thanks,

-b.

ether, gpio (where we attach an avalanche diode torturing device), sd,
