New PCBs status (UPDATED 20181130)

ALPHA 6.2.3 Fire image

TECHNICAL INFO: (JLCPCB)

Gerber file: openSX70_ALPHA_V6-2-3-20181104_2018-11-06_Y3 / Build Time: 72 hours / Layers: 2 / Dimension: 96mm28mm / PCB Qty: 10 / PCB Thickness: 0.6 / PCB Color: Blue / Surface Finish: ENIG-RoHS / Copper Weight: 1 / Gold Fingers: No / Material Details: FR4-Standard Tg 140C / Panel By JLCPCB: No*

COST: 25,37€ + SHIPPING + EU IMPORT DUTIES

STATUS: 20181130:I have tested and “blinks” in two colours. Have to test “camera operation” but I am quite sure it will work. LED footprint is wrong and I have fixed it for the next batch. Still I can solder with difficulty and make it work. Already fixed it for the next batch 6.2.4 Alpha. The “gold” ENIG finish is nice and easy to solder. Not sure it is worth the 5X price increase.

COMMENTS: Looks nice, LED footprint perhaps is too small or hard to hand solder. Outline fits perfectly. I wonder how hard is going to be soldering on ENIG (gold). Photodiode footprint looks spot-on. 20181130: I have to test with a camera in the VF to see if the magic happens. Hope it does or it can be easily fix in the next batch.

ALPHA 6.2.2 Fire image

TECHNICAL INFO: (JLCPCB)

Gerber file: openSX70_ALPHA_V6-2-2-20181103_2018-11-04_Y2 / Build Time: 72 hours / Layers: 2 / Dimension: 96mm28mm / PCB Qty: 10 / PCB Thickness: 0.6 / PCB Color: Green / Surface Finish: HASL(with lead) / Copper Weight: 1 / Gold Fingers: No / Material Details: FR4-Standard Tg 140C Panel By JLCPCB: No

COST: 4,37€ + SHIPPING + EU IMPORT DUTIES

STATUS: 20181130:I have tested and “blinks” in two colours. Have to test “camera operation” but I am quite sure it will work. LED footprint is wrong and I have fixed it for the next batch. Still I can solder with difficulty and make it work. Already fixed it for the next batch 6.2.4 Alpha. The HASL finish is OK, but doesn’t look as nice.

COMMENTS: Looks nice, LED footprint perhaps is too small or hard to hand solder. Outline fits perfectly. HASL looks definitely easier to solder. And way cheaper.

STATUS: 20181130 Build one and sent it to Clément. Seems to work but I don’t like it: footprint of switches (was a catch all) is not good. Holes are too small. Have to rethink it.

COMMENTS: ENIG and black but I’m not so sure about this one! 20181130: Maybe it could be smaller? Not sure.
