Hi Gene,

Your board is already a work of art.

Nice update Gene!. Can't wait to see the PCB once all the components are soldered.

Hi Gene,

This is looking fantastic : ) It's nice that you're not afraid to change angles to get your components located where you want them : ) Regarding circle, the low-cost PCB manufacturers seem fine with routing out shapes, e.g. with the mouse-bites, so that could be an option too (i.e. lines on layer 46 in EAGLE). They do sometimes query via an e-mail to double-check they've got it right, so if you're on a timeline that's something to watch out for.

For the LGA package etc., my pre-heater and hot air tool are underpowered, so recently I've thought about trying low-temp solder paste with it. I don't know if it will work though! I'll try it in a few weeks time, I'll be sending a couple of PCBs to be made in a week or so. The one I went for is called Qualitek Delta 670.

Anyway, it's a really nice design and layout, it's clear a lot of effort went into it! It takes me days to route out stuff tidily.

professional PCB design... Really! Can I suggest something that has already created issues for me in the past?

Well, I suppose you say yes [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-f567c6d6-2d86-4d9b-8523-27bdb5004850/contentimage_5F00_1.png:16:16] The idea of the holes for air flow is really great. The top left two holes, in my opinion, are too near to the border, so you risk that during the fabrication the PCB will be damaged as they make holes drilling the finished printed PCD (at least in most of the cases). As well as the same holes seem dangerously near to the PCB track.

PCB looks great. How are you going to do the SMD assembly? Are you going to use paste with a stencil? I don’t recall whether you have a reflow oven.

Like Frank I’ve never done well cutting circular boards but I will admit to using a belt sander to clean things up. Made quite a mess.

Hope your airflow works out. How much current do you think you’ll end up putting through the slip rings?

Hi Gene,

really nice... How will you trim the PCB? I have never been able to make a neat job of it.

Gene,

Impressive PCB design. I've done a few simpler ones in my time but nothing like this.
