I had the same good experience with PCBway.

I used these 0.9 * 0.9 mm GaN FETs, and that does not mean 0.9mm gate 
length:

https://www.digikey.de/product-detail/de/epc/EPC2038/917-1138-1-ND/5774048

and used the proposed Altium footprints from EPC. These pull the
solder mask onto the pad which is unusual but maybe essential for
a smooth soldering experience. I'm sure that EPC have experimented with 
that.


PCBway emailed me directly and we cleared that up that it was intentional.
They still produced the board on the same day, and soldering was easy.
Very satisfied customer.

Nevertheless I'll try JLCpcb next week. They now have a proxy man somewhere
here in .de who gets one box from China a day and forwards the contents
to the different customers after the customs work is done, via normal 
local registered mail.

The import VAT is then already done and billed by JLCpcb.
DHL Express is a royal pain to deal with.

Cheers, Gerhard

I was pleasantly surprised last week when Seeed Fusion contacted me to
point out a problem where two vias were too close together (by a couple
of thousandths).  They asked if they could reduce the hole diameters
slightly to correct.  I agreed, they made the change, and the boards are
with DHL right now.  So they do have a process to kick at least some
issues to human beings for resolution, rather than just rejecting the job.

BTW, two things I've learned from my current project:

1.  Seeed claims that they can do down to 4mil trace width and spacing,
and down to 0.2mm holes, but those add extra charges.  For their $4.95
for ten boards deal, the minimums are 6mils and 0.5mm holes (why can't
they pick one dimension system for the specs???)  Go smaller and the
price goes up 10x or more.

2.  Where I had the clearance problem was on a USB C connector.
Whatever advantages they have, they are a pain to route and solder.  The
one I used (which seems fairly common) has both through hole and SMT
pads, and the space to get all the signals lines connected and routed is
very, very tight.  The smaller trace and hole sizes would have made the
job easier, but I wasn't willing to jack up the cost for that.

Re: [time-nuts] OCXO Support Board

[Bob kb8tq]

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 often are non-issues. A 
fancy
program would let you “allow” ( = suppress ) the error once you checked it out.

2) Zone based rules. The region under a BGA may be very tight in terms or 
clearances.
The rest of the board likely will not be. Having rule zones helps deal with 
this. 

3) Silk screen / mask rules. Getting the silk screen so it either shows right 
or is suppressed
is a pretty basic process. Doing it manually is a major pain. Indeed a number 
of “pro”
packages have the same issues. 

4) Extras. Duplicate holes should not get into the drill file. Dangling trace 
bits should be
spotted and flagged……..

Yes, this could go on and on.

No, the cheap board houses don’t check for this stuff. They just build and send 
it
back. If there’s a gotcha, you get it on the board.

Could you give a few examples of the more obscure rules?

Do the low cost board shops give you enough info to check them?

Thanks.

Re: [time-nuts] OCXO Support Board

[Graham / KE9H]

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 combination is very adequate.

Re: [time-nuts] OCXO Support Board

[Bob kb8tq]

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 have stopped things
dead if we tried to run it at work. We had at least 4 layers of rules checking 
that ran before the board finally went out for fab …..

Re: [time-nuts] OCXO Support Board

[Mike Ingle]

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.  While
Altium designer is more mature, and a little smoother to use, all of the
programs have quirks, and require that you become familiar with them.  So
far I am not seeing any limitations in Kicad that would prevent getting
good boards made.  And, many  prototype oriented houses accept Kicad PCB
files directly (for example EUROCIRCUITS) , which saves you from generating
Gerbers and drill files.

And Kicad just keeps getting better.

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 go back to / hand to others
to show what the board was intended to do.

2) enjoy a few adult beverages while waiting
3) go back a re-check everything
4) send it out to the board house

[time-nuts] OCXO Support Board - PCB Source

[Bob Martin]

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 price determinants. I have done 6 layers with
no problem. No one likes paying for shipping but you do get
actual one week delivery to Colorado for two layer boards.

Here it is:

These are the Gerber files as used by PCBway to produce my boards.

2 buglets:

- the 2 mounting screws for the 10811 should be slightly bigger.

   Drill as needed

- Unless the oscillator delivers only a small signal, the 2 emitter
capacitors should

   each get 22 Ohms in series to adjust gain.

This will be addressed in V3. Circuits are included, comments and small
change

requests are welcome, could be done shortly thanks COV19.

Re: [time-nuts] OCXO Support Board

[Wes]

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 an order of magnitude since then it seems.  (I can remember laying out 
boards by hand, taping up the artwork 4:1, reducing it photographically, 
exposing and etching boards.  So today's technology is magical.)


Many of you are doing some awesome work.  Well done.

Wes  N7WS

Here it is:

< http://www.hoffmann-hochfrequenz.de/downloads/ocxo_carrierV2_pack.zip    >

These are the Gerber files as used by PCBway to produce my boards.

2 buglets:

- the 2 mounting screws for the 10811 should be slightly bigger.

  Drill as needed

- Unless the oscillator delivers only a small signal, the 2 emitter 
capacitors should


  each get 22 Ohms in series to adjust gain.

This will be addressed in V3. Circuits are included, comments and small 
change


requests are welcome, could be done shortly thanks COV19.


cheers, Gerhard

Re: [time-nuts] OCXO Support Board

[Bob kb8tq]

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 make ok boards. 

Since the parts range is limited, you will be putting a few things on 
yourself. I’d guess that 90% of the parts on a typical board will be 
things they can supply. Is there another gotcha? Not at all clear (yet). 

The outfit above has two categories of parts (basic and extended). It
appears that when you go into the extended group, there may be some
minimum order gotchas ….

Re: [time-nuts] OCXO Support Board

[Bob kb8tq]

Hi

There are a number of free ( = there is no license fee ) pcb layout programs 
out there. 
One of the many is KiCad. It’s not that hard to use. It is very popular. There 
are a lot
of YouTube videos and blogs detailing how to do this or that with it. Laying 
out a board
to mount an OCXO on is a pretty good starter project. 

Once you get going, a board is a weekend project. Indeed, a simple board might 
be an
evening project. There’s not a lot involved. 

Once you have your layout, it goes off to any of a number of outfits. Seeed 
Studio is 
one that many people use. WellPCB is another that comes with a lot of 
recommendations. 
As long as you stick with < 100 mm x < 100 mm parts a number of places will 
sell you
boards for 50 cents each. 

Shipping does cost $20 to $30, so doing more than one board at a time is a 
pretty good
idea. If you are laying out five boards a week, batching them up isn’t the hard 
part :)

While most don’t seem to use it, many board houses also offer assembly / pick 
and place
services. On a board that uses simple parts, that might take out the whole 
assembly
process. No idea (yet) how well that part goes ….

Hi

In this era of $5 for 10 boards from China, a lot of folks have laid out various
boards. They aren’t “ready made” but they get past the dead bug stuff.

[time-nuts] OCXO Support board

[Wes]

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: 
https://www.tindie.com/products/AnalysIR/10mhz-ocxo-frequency-standard-module-or-kit/?pt=ac_prod_search 
with a footprint that will accept the MV80.


Does anyone know of such a source?

Thanks, Wes
