developer notes on tools we use or thinking about


Automated manufacturing notes.

We want to start automated picknplace assembly of v3.1.

They would do the CAMfiles (I think teach the machine manually), but I expect it takes time and I don't like that method. I asked for the CAM format. I couldn't get the required data format yet :-(. But they said it's ASCII, so it will be trivial to perl on-site.

Miska's script outputs the placement of components, grouped by component values.

First version of Eagle script produces sorted component placement data as shown below for top and bottom layers separately.\n

; num [ id] [   pack ] [            part value ] [  X ] [  Y ] ANG
[ 33]   C34      C0805                   0.001µF  84809  93946 180
[  2]    C3      C0805                     0.1µF  34097 119561  90
[  3]    C4      C0805                     0.1µF  35660 123029 180
[ 39]   C40      C1206                    0.33uF  85027  81246   0
[ 69]   C70      C1210                       1uF  69149  33421  90

(yes, they said it's an ASCII format, will be perl-ed to match at the site). Many thanx, Miska.


SW:

Eagle schematic and PCB editor (and it's license terms!) from http://www.cadsoft.de/

I use the Eagle 4.11 professional license, but eagle with any license can view sch or pcb, and any can edit the one-page (therefore a bit clumsy looking) schematic. Eagle is a relatively shitty program. The lack of some very simple functions make your life hard.

Eagle wishlist:

eagle working list:


GEDA GNU electronic design automation.

These software are good for simple design. VEMS team mostly uses Eagle. Autorouter functionality is poor, but 2 layer boards must be routed manually for sane result anyway :-)

[eagle help]

do you know how to share info between PADs and Eagle schematics and layouts? Have links? A friend insists on PADs (which he paid serious money for) and would make smaller boards (eg. stepper-driver for a special app, special form-factor).

Spice and clones (eg. acs) for simulation

[LTspice]


HW:

scopes (like Vellemann K7103), signal generators

Virtual trigger signal generator by Ray Hall, handles the most common stock trigger arrangements:
