Does anyone have experience with PCBArtist?  It looks pretty good for
2-layer board up to 60 in^2 for $33 but I have no experience with it.  I
was looking at Eagle PCB but it's pretty expensive for a 4-layer capability
version.

Thanks,

version.

I have the Maker license from CadSoft (Eagle).
It can do 6 Layers and it costs 169.- U$ but it is limited to 160 * 100mm²
https://cadsoft.io/pricing/

KiCAD may be a nice alternative:

With PCBArtist I do not have any experince.

A litte apples and oranges here :)

The Eagle Light version can be used for free for
non-profit purposes and works for up to 4x3.2inch
with two layers.

If you don't have any personal preference, then
KiCad is definitely the way to go. It has improved
dramatically since it got the CERN treatment and
doesn't cost a cent regardless of size and layers.

Well, maybe big apples and little apples :-)

The Eagle Light version can be used for free for

Our company has been committed to Eagle for about 5 years.  The problem
you face is that your investment in IP (schematics, board layouts,
component libraries, etc) vastly out-values the software.  With a
proprietary system, you're either locked in or face huge costs in
converting.

If you don't have any personal preference, then
KiCad is definitely the way to go. It has improved
dramatically since it got the CERN treatment and

Indeed.  I am just about to pull the trigger on KiCAD company-wide.  I
think it is ready for the kind of work we do (4 layer boards, some with
high current/voltage traces).  The only thing holding me back IS our
investment in IP.  Maybe with Eagle 7 using XML for data storage,
someone will write an Eagle to KiCAD converter.

I strongly recommend learning KiCAD (a fairly daunting task) before you
get any significant amount of IP committed to a proprietary format.

I've used elecrow a lot, for 2 and 4 layer 6 yhou track & gap. Not the

Hi Randy

To compare prices you can have a look at

http://pcbshopper.com/

I have used Elecrow and also dirtypcbs. Both were excellent. These days
you can get beautiful double sided, PTH boards with solder mask and silk
screen for practically nothing. Cutouts, slots, non-pth holes, choice of
solder mask colours available for free.

The going rate starts at $10 for 10pcs 50x50mm. Practically free
shipping if you can wait, otherwise ~$25 for DHL etc.

The low prices are achieved by pooling many peoples designs onto one
production panel. So there is usually one price if your board is less
than 50x50mm, then the next price if it is less than 100x100mm.

(I threw out my bubble tank after not using it for 10 years...)

John

Make sure to get the 'latest' version, it really makes

I can recommend OSHpark as pooling service if you do not
need the boards urgently or have specific requirements
regarding layers or vias or whatnot.

I am designing a voltage reference programmable fro 0 to
10 volts with a LTZ1000 reference and settabiltiy of
0.1ppm and I need a PCB fabbed.

I've done quite a number of PCBs via OSHpark, from small
breakout boards up to quite complicated FPG solutions
used in a 4k cinema camera.

The essential points with OSHpark are (in a nutshell):

  • drill sizes are "optimized" i.e. they have certain
    tolerances and you will not always get what you expect..
  • you have to use one of the three different stackups
    if you like them or not :)
  • there is no electrical test for the PCBs
  • there is no impedance control done by OSHpark
  • you always get multiples of three boards
  • the boards are purple with white silkscreen and
    ENIG finish on the pads.

Hope that helps,
Herbert

to ask me ...

I'm surprised nobody has mentioned Sprint-Layout from Abacom:

http://www.abacom-online.de/uk/html/sprint-layout.html

Back in January 2015, Sam Reaves posted a nice writeup of this package.
Based on his post, I tried it, loved it, and bought it (it's very
reasonable).  I also have KiCAD, the free version of Eagle, and the
DipTrace demo version.  I've gotten to where I can use all of them, but
when it comes time to do a board, I almost always go straight to
Sprint-Layout.  Certainly, anyone who balks at the steep learning curves
of KiCAD, Eagle, and DipTrace will just love the intuitive operation of
Sprint-Layout.

I've pasted part of Sam's original message below.

Best regards,

Charles

The excellent, not free but very inexpensive (49 Euros) PCB package from
Abacom called SprintLayout6.0 (link below). If you are outside of the EU
the cost is 19% less (minus their VAT).

You can download a demo that does everything but save your work for free.
And they take PayPal. There is also a free viewer that can view the native
files. Although you may never need it they have excellent support. Bugs
have been minimal and the product has been very stable for me. I have run
it on XP and Win7 32/64 with no issues. Licensing is simple and you can
install on more than one PC as long as you use it only on one PC at a time.

Here is a short list of exceptional features that this program has that is
(for me) a good bang for the buck (or euro!)

  1. Ability to import 274X Gerber files to allow you to easily turn them
    into an editable PCB file (I found this really handy to create PCB's from
    Eagle and other PCB CAD package files.

  2. Ability to import a BMP file from a scanned image and scale and float it
    in the background so that you can trace over it to create editable artwork.
    Really handy for those old designs or for working from artwork from
    magazines or the back of the ARRL handbook.

  3. Easy Ground plane/Power plane pour. Pads can be set as thermals to
    connect to the plane with independent connection to either plane. Zone
    pours and cutouts can also be done.

  4. Support for four layer boards.

  5. Easy to use footprint creation tool for SMT/Thoughhole parts

  6. Easy to use part library generation. Many parts available.

  7. The ability to rotate parts in very fine increments.

  8. Photo view mode that shows you exactly how the finished PCB will look.

  9. Isolation generator for creating milling plots for making PCB's on a CNC
    mill. Worth the price for this feature alone. When used with Bernhard
    Pahl's SL2M3 program which converts the HPGL milling plot files and the
    drill/mill data to G-Code for running CNC programs like Mach-3. With some
    manual editing of the G-Code text one can use the program with LinuxCNC.

  10. Simple point to point semi-automatic router that works with manually
    placed connections.

  11. Moving the reference datum (X0 , Y0) point for all layers is really
    easy and I have not found any other program that does this as easily.

  12. Perhaps most important: The program is very easy to use and learn and I
    have made dozens of boards using it in all of the modes.

I'm surprised nobody has mentioned Sprint-Layout from Abacom: <http://www.abacom-online.de/uk/html/sprint-layout.html> Back in January 2015, Sam Reaves posted a nice writeup of this package. Based on his post, I tried it, loved it, and bought it (it's very reasonable). I also have KiCAD, the free version of Eagle, and the DipTrace demo version. I've gotten to where I can use all of them, but when it comes time to do a board, I almost always go straight to Sprint-Layout. Certainly, anyone who balks at the steep learning curves of KiCAD, Eagle, and DipTrace will just love the intuitive operation of Sprint-Layout. I've pasted part of Sam's original message below.

Indeed.  I am just about to pull the trigger on KiCAD company-wide.  I
think it is ready for the kind of work we do (4 layer boards, some with
high current/voltage traces).  The only thing holding me back IS our
investment in IP.  Maybe with Eagle 7 using XML for data storage,
someone will write an Eagle to KiCAD converter.

What you have in schematics and layout does not matter that much,
if you have the money to keep an Eagle license around. In my experience
the only IP that matters are reviewed and known good schematic symbol
and footprint libraries. Schematics and layouts of circuits that are
more than a couple of years old are only worth as a reference for the
new design. New devices come so quickly that a design done 5 years ago
would look very different if done today. And often with better performance
and cheaper too.

Depends entirely on the industry.  Consumer electronics, I agree fully.
Industrial and commercial products, not so much.

Our main product, the Roy induction heater is a perfect example of the
latter.  It uses a fairly large board with mixed logic and power
sections.  Over 400 components.  I haven't made a meaningful design
change in about 4 years.  Every 6 months we consider suggestions made by
customers and employees.  So far very few got through the review process.

I'm now doing the board over from scratch but only because my hand was
forced by Atmel EOLing my microprocessor.  It really p*sses me that they
EOL'd the part with no advance warning. There is tremendous IP value in
that board and the custom component library.

Yes, the new board will have more functionality, will protect the power
semis better and will move much of the low level hardware into software
but none of that was worth the effort it's going to take to port the
firmware functionality over to the new processor until I was forced to
do so.

Eagle's new AutoDesk-style of licensing forced the issue to KiCAD for me.
