| xobs | mithro: possibly. It depends on how production goes. It's looking more and more likely that I'll make it to LCA though. | 00:45 |

| chr127 | ssb, When did you order? | 13:41 |
| xobs | chr127: We're still trying to produce PCBs. We disqualified the previous PCB vendor because they failed to produce PCBs 8 times. | 14:02 |
| xobs | The new PCB vendor has failed once, but they are trying again and they have actually explained what went wrong and what they're doing to fix it. | 14:02 |
| chr127 | Alright, Ill just wait. | 14:05 |

| xobs | To be specific, during the hard gold plating process they didn't take into account the fact that the USB pads are close together, and the gold fingers fused slightly. The solution is to adjust the current, or separate the pads slightly. | 14:08 |
| xobs | Who knew hard gold plating would be so difficult? That's actually been the root cause of a lot of the manufacturing issues... | 14:10 |

| xobs | While the factory has been busy, though, I've been working on Foboot 2. The biggest change is eptri, though spi programming is also a lot faster. | 14:18 |
| ssb | chr127, a long ago, during the campaign. | 14:18 |
| ssb | xobs, re on hard gold yield woes: Out of curiosity, who is taking financial hit here? Factory, you or crowdsupply? Or that is a sensitive question? ) | 14:21 |
| xobs | ssb: that's one of those things that you need to negotiate. Since the factory promised they could do a thing and failed to deliver, we didn't pay for the boards. We did pay NRE though, so they were compensated for that at least. | 14:25 |
| xobs | What we did end up paying for was part of the NRE at the new PCB shop. But I feel it's worth it in the end since I'm familiar with this new board house. | 14:26 |
| xobs | NRE: Non-Recurring Engineering -- the cost it takes to develop a process. When you build a new PCB, you pay NRE upfront and then a per-board cost afterwards. It means design changes are painful and expensive, but ongoing production costs are much lower. | 14:27 |
| LWK | you could defiantly shrink the pad size base on a quick look at the usb spec https://usercontent.irccloud-cdn.com/file/eYXwnklh/usb_20%20fig%206-9.png | 14:27 |
| xobs | LWK: Definitely. The pad size comes from the original Tomu I think, when a business card was required to hold it in there and the PCB wasn't guaranteed to be straight. Ah well, legacy. | 14:28 |
| LWK | ah yes with out a case you have a lot of wiggle, make sense to try for as much contact as posible | 14:32 |
