I just finished building all of the HF32 batch 1 units this week. Some interesting stats/facts I wanted to share.
~6% of HF32 are prototype units from the initial test run.
~41% FR4 Top Covers
~59% Alum. Top Covers
~82% Black Top Covers
~13% Red Top Covers
~5% Gold Top Covers
~87% BW eInk
~12% BWR eInk
~1% BWY eInk
0% scrap on bottom PCBs
~0.5% scrap on middle PCBs
~2% scrap on eInk displays
I scrapped 2.5 FR4 covers for every 1 that I shipped. :-(
I scrapped about 18% of the aluminum panels I purchased.
~14% of bottom PCBs had a blemish on them.
Every Bottom PCB had a resistor mod on it.
