jtwrace Posted March 13, 2016 Author Share Posted March 13, 2016 I guess you have to thoroughly test your pre-production board to ensure that no further changes are required before you order production parts. How long do you expect that process to take if there are no unanticipated surprises? I predict June shipping.

rickca Posted March 23, 2016 Share Posted March 23, 2016 It would be great to have a status update on your pre-production board, even if it's still too early to talk about the design and technology of your power supply.

JohnSwenson Posted March 23, 2016 Share Posted March 23, 2016 It would be great to have a status update on your pre-production board, even if it's still too early to talk about the design and technology of your power supply. The pre-production board is being layed out right now. I'm taking the lessons learned from the 4 previous boards to make this board very reliable and robust. I've managed to get rid of a lot of parts so it is easily fitting on the board size that fits in the case we chose. The last time I did an all-together-on-one-board it was very tight and took a lot of work to cram it all in, this is going much easier. John S. Link to comment
rickca Posted March 23, 2016 Share Posted March 23, 2016 Thank you, John! Streamlining things while making the product more robust is always a good sign of progress.

JohnSwenson Posted March 31, 2016 Share Posted March 31, 2016 Just replying to get progress updates from this thread on whateveritis I'm still working on the layout. It's getting close, probably done this week. Working on it right now. Well obviously reading forums RIGHT now, taking a break from parts placement optimization, this is where I stare at the screen for hours on end thinking "if I move this here I get shorter routes for this net but longer for that, then if I move this other thing, I could cut down on that net, then move this group over here that would free up room for this part, which makes that better.............." It looks like nothing is happening, just staring at the screen, but it is actually the most important part for getting the placement just right so the routing goes easy. John S. Link to comment

I'm surprised there isn't any sort of simulation optimization for this type of effort. It would make sense to me that at least that would get one in the ball park if not ideal.

rickca Posted March 31, 2016 Share Posted March 31, 2016 For jtwrace, here's a bit of discussion about using tools to automate parts placement optimization New to PCB design - why doesn't auto placing components exist? - Electrical Engineering Stack Exchange Pareto Audio AMD 7700 Server --> Berkeley Alpha USB --> Jeff Rowland Aeris --> Jeff Rowland 625 S2 --> Focal Utopia 3 Diablos with 2 x Focal Electra SW 1000 BE subs i7-6700K/Windows 10 --> EVGA Nu Audio Card --> Focal CMS50's Link to comment
rickca Posted April 6, 2016 Share Posted April 6, 2016 How do you manage the logistics for a device with 216 parts? The prospect makes my brain hurt.

Superdad Posted April 6, 2016 Share Posted April 6, 2016 How do you manage the logistics for a device with 216 parts? The prospect makes my brain hurt. Well fortunately on the board itself there are "only" about 52 different parts due to lots of the same part being used in places. Even more thankfully, our board house does all the ordering (with most parts on reels) and inventory, though I do pay extra for the privilege of having them do so. But to keep costs down, I build big spreadsheets comparing the volume prices between the distributors as no one distributor has all the items anyway. That part can be a bit mind-numbing (my task this week), though it takes orders of magnitude less brain power than it does for John to design and lay out a circuit like this. 4 power domains, 4-layer board, parts on both sides, FPGA programming, and control of noise, impedance, currents, and heat. That's the stuff that makes MY brain hurt. (But I must say, I do take a little pleasure in having gotten to the point where I can be reviewing one if his preliminary boards layouts and catch some semi-glaring error that he just had not yet picked up on. Sometimes I wonder if he puts them in there just to help me me feel useful…) UpTone Audio LLC Link to comment

Superdad Posted April 6, 2016 Share Posted April 6, 2016 Why would a power supply add on be micro SD card equipped??? Well since it uses an FPGA (with a VERY, VERY slow running clock), the SDcard slot is there just in case we ever need to issue a firmware update. The slot will be empty, but if the need ever arrises we could either mail out microSD cards with the code ready to auto-load, and/or make a download image available. UpTone Audio LLC Link to comment

rickca Posted April 14, 2016 Share Posted April 14, 2016 I hope your pre-production board is soon in the hands of your PCB fab. It would be so nice if you could start talking about your technology at AXPONA.

Well the board is almost done, but I can't go to AXPONA, I'm chained to the chair in the lab, there is SOOO much to do, at least 4 different projects.

The fact that you will be wrapping this one up and quickly moving on to another one is a good thing, though!
