Re: [time-nuts] OCXO Support Board

Hi Well, a full list of all the rules we ran against would run about 10 pages. I think that’s getting pretty far off topic for TimeNuts. I also, quite frankly never bothered to memorize them all. A few examples of what one *might* do: 1) “Allow” a violation. Things like courtyard overlaps

Re: [time-nuts] OCXO Support Board

Most of the PC board manufacturers run a rules check for your board against their process capability. I have had them catch some things from time to time that the design tool missed. For commercial business, I more rules checking is always better, but for hobby and personal purposes, I think the

Re: [time-nuts] OCXO Support Board

Hi Going from “pro” layout tools to KiCad, the only big thing that seems to be missing is a “full feature” DRC (design rules check) process in KiCad. The tools I worked with in the past had much more fine grained rules checking features. Probably not a big deal for a basement project. It would

Re: [time-nuts] OCXO Support Board

Hi All, I will second Bob's comment on choosing a program with PCB - Schematic integration. I can heartily recommend Kicad. I own Altium designer, but work remotely for an American firm from Germany. The US office uses PADs. We have finally agreed on projects going forward to both use Kicad.

Re: [time-nuts] OCXO Support Board

Hi I would toss in: If you are starting from scratch, pick a program that allows you to easily enter schematics as well as PCB layouts. Take the time to learn both sides of the program. That will give you an automated check between the schematic and the layout….. It also gives you a document to

Re: [time-nuts] OCXO Support Board

Thanks Mark for reminding me, spend 3 hours this morning reviewing designs to be released. Found a couple of problems. Also went back to look at the OCXO boards I released in 2018, found a problem on the board with no Amp, the SMA is not grounded. Easy to fix, but if some one wants new Gerber

One thing that I recommend is that after completing the layout is to: 1) step back and wait a few days 2) enjoy a few adult beverages while waiting 3) go back a re-check everything 4) send it out to the board house You'd be surprised how often simple, subtle, not so subtle

It is nice to see PCBway mentioned. I've used PCBway for years. With over 30 designs, I've never been disappointed. Their best feature, aside from pricing, is the ease of getting quotes. They don't care about the number of holes in the board. Board dimensions, thickness and volume are the main

I can remember "wiring" up some X-band test equipment with WR90 waveguide, flanges and a brazing torch. We "miniaturized" the missile hardware by using 1/4 height W/G. Circa 1966. Wes On 5/13/2020 9:12 AM, ew via time-nuts wrote: You give away your age, was there did a lot of it and off to

Thank you to all who have written, on and off list, with offers of boards and advice on how to make my own.  Much appreciated. I think I'm on to one that meets my fairly simple needs and uses through-hole components.  I have done SMT construction in the past but things have shrunk in size by

Hi Some of the Chinese outfits flip that model around the other way. You get to use the parts they have in stock. Setup *appears* to be dirt cheap, as well as the basic parts costs. One of many examples: https://jlcpcb.com I haven’t used them for assembly, but the do

In a moment of weakness and impulse, for no particular reason I bought a Morion MV80 on the auction site.  Now I'd like to power it up and am looking for an easy way to do that. So, rather than reinventing the wheel, I'm looking for something similar to this:
