Milled boards

Re: [Homebrew_PCBs] Milled boards

2005-12-25 by James Washer

Nice job John.

Can you answer a few questions for me? How does one get from an Eagle "brd" to whatever CNC instructions (or whatever they are called, I don't know anything about CNC, sorry).

What kind of a mill are you using?

If you will design square or rectangle pads and will add square to each
track's corner, the CNC
will spend less time to mill (only X and Y movement instead of arcs).

Re: Milled boards

I run CNCPro and it does arcs very fast. The whole idea is to make
a board in Eagle and then cut it out. If it flys then the artwork goes
off to the PC House. I did square and six sided pads on my first
boards that I sold. (Piker 3 and Piker 4X) The slow down is caused by
the traveling salesman syndrome. When you convert the Eagle BRD to
GCode you will get a trace cut then the machine will travel across the
board and do a second one instead of doing one next to the first. When
I do a board with TurboCad I make a trace of the artwork in the order
I want it cut. After it get converted there is no extra traveling. I
get a very quick GCode. But in this case I am using Eagle to make the
code.

Re: [Homebrew_PCBs] Re: Milled boards

2005-12-25 by James Washer

Two questions

1) Is it "reasonable" to mill double sided boards?
2) Will Eagle(and scripts) provide code to do the drilling (I'd assume so, but I don't like to make assumptions)

Re: Milled boards

2005-12-25 by crankorgan

Two side is done using two register pins. The problem is you will
have to add jumpers to make connections from one side of the board to
the other. With a little thought you can make most boards single
sided. If you let Eagle route your boards you will get double sided
boards 9 out of 10 times.

Re: Milled boards

2005-12-25 by Dale Mosby

The idea of being able to use a cnc mill to create two sided boards
looks great. Before investing in this technology I would like to
observe the process. Is anyone in the greater Portland, Oregon or
Vancouver, Washington metro area using a mill to cut and drill two
sided boards?

Thanks, Dale daleatarchcapedotcom

Re: [Homebrew_PCBs] Re: Milled boards

2005-12-25 by James Washer

Yes, I understand the need to arrange for either jumpers or "rivets" from one side to another. Thanks

Re: [Homebrew_PCBs] Re: Milled boards

Excellent question.

Is there anyone in the Reno/Sacramento area that would allow me to observe a board being milled?

thanks

Re: [Homebrew_PCBs] Re: Milled boards

Eagle does allow you to auto route on one side of the board only. By
indicated "N/A" in the top side under "Autorouter Setup", you will then have
"Autoroute" on the bottom side only.

Re: Milled boards

In the case of designing a Stepper Chopper board, autorouting is
useless. Certain traces have to be run certain ways. Autorouting works
great for digital only circuits. But don't use it for audio and RF
circuit unless you want extra noise or oscillations.

Re: Milled boards

I use jumbers or the resistors themselves to make a jump so I
don't need a double sided board.

Re: [Homebrew_PCBs] Re: Milled boards

2005-12-26 by James Washer

Well, I too have done this in the past.. but my boards are getting more comples... current board consists of one 28pdip, and four 16pdid chips, 3 DB9s, 2 power connectors, 8 ADC channel connectors, a TWI interface, about 40 caps, 6 inductors, 2 fuse holders, and a power supply..

All on a 3x4inch board... It's getting harder and harder to put this all on a single sided board

Re: [Homebrew_PCBs] Re: Milled boards

Thanks for the advice.

I am just starting to learn my electronics and certainly distinction between
digital and analog devices is something that will take experience and time
to learn.

Is there any good websites that will give me an idea where to start?

Re: Milled boards

James,

There's lots of info on Eagles support list. You can find it on their
website.

I've only done a few double sided boards with Eagle, but if you're
going to attempt it, you'll probably want to use the tRestrict and
vRestrict layers. Basically, you draw polygons in those layers, and
the router will not try to route the traces in the areas you specify.

I usually use tRestrict over IC's because I don't want to deal with
trying to solder both sides of the board there, or deal with vias
underneath the IC's.

A lot of double sided boards can really be single sided boards with a
few jumpers, and the restrict layers help make that possible.

Kevin
