gEDA-user: Thermal pads overlapping regular SMD pads and solder mask
I'm working on a footprint for an SMD LED (Optek OVS5MWWBCR4) for which the manufacturer recommends larger SMD pads for thermal reasons, with appropriately applied solder mask only to the actual electrical contact areas, presumably important to assist accurate placement of the LED. It looks like I can in fact set different solder mask clearances for overlapping pads, but I have not been able to make a pad entirely covered with solder mask. Is this possible? I found that doing changeclearsize to 1 mil gave almost complete solder mask coverage, but some copper was exposed. See page 10 of the OVS5MxBCR4 data sheet PDF for the recommended PCB layout. http://www.optekinc.com/datasheets/OVS5MWWBCR4.pdf Does anyone have any recommendations or tips for me on creating a pcb footprint like the one on page 10 of the data sheet?

gEDA-user: NGspice and GNUcap Non-Linerar Dependent Sources
Hi Gang, I've been playing with ngspice and gnucap and have gotten good results with the Non-Linerar Dependent Sources eg ASRC B devices in ngspice. I mostly use those with VC-Switches to make full wave bridges, SCRs, Triacs, etc... Though I see that they are not supported in gnucap. I guess the alternative is to use POLYs. I've looked around and except for a short description in the gnucap manual I haven't found a comprehensive howto on how to use them. I sapose you would want a curve fitting program to help you generate the coeficents like grace, or simfit, or you could use the fit function in gnucap. However this isn't supported in ngspice, so you couldn't use that model in both. Are POLYs really that much better at solving convergence problems to be worth the extra trouble? Is there a good into or howto on how to use them? Are negitive coeficents even legal? Inquireing minds want to know. ;-) Thanks, Clif ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

gEDA-user: OT: Gilbert Cell
Has anyone worked with Gilbert Cells? I'm having a lot of trouble with one from ON Semi, MC1496, formerly Motorola's part, I think. The thing is configured as a product detector. There's 2 input frequencies and they both mix down to 5 kHz. That part works well. But, the chip just happens to oscillate at 5 kHz all by itself even without the local oscillator running. Go figure. There's also a very slow moving, 400 Hz or so, modulating the 5 kHz. I cannot for the life of me, figure out where it's coming from or how to get rid of it. I appreciate any help. gene ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
Re: gEDA-user: Problems compiling PCB Release 20100929
Thanks guys. I built gd-2.0.35RC5 from source with no problems, and then pcb compiled. I also tried 'sudo apt-get build-dep pcb'. I didn't know about the 'build-dep' option. I like that, so I did it and there were four or five programs that got installed. On 11/10/2010 05:59 PM, Peter Clifton wrote: On Wed, 2010-11-10 at 17:16 -0500, d...@umich.edu wrote: Thanks. That got me past the dbus-1 error. Now I am running into this: Since _a_ version of PCB is in the Ubuntu repositories, this can be a quick start to get what you need to build that particular version. Things should not have changed too much in terms of build requirements since then. sudo apt-get build-dep pcb That should help get you started. 'PCB 20100929' runs fine now. Thanks again, Dave P.S. Will my Ubuntu 10.04 system get confused if I install both the Synaptic package of pcb along with the compiled version? ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

As Gilbert works for Analog Devices, I'd poke around there for ideas: http://www.google.com/search?q=Gilbert+Cell+site:Aanalog.com The most interesting use I've see for a Gilbert like device is for mathematical analog division, think it was using a couple of AD630's. Not finding that one right now, but this one might be more of direct help to your problem: http://www.analog.com/static/imported-files/rarely_asked_questions/computation.pdf ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
gEDA-user: Comments on pcb's g-code exporter HeeksCAD/HeeksCNC FOSS program for pcb milling
The g-code exporter looks great! Right now I am looking at EMC2 simulate the milling of a pcb design!! I like that the gound plane outline is machined. The circular pads could use some more lines to round them out. Have you thought about programming g-code arcs (G02, G03) for them? HeeksCAD/CNC does this (see below). Please, consider a dxf export of the outline so that users can put the artwork into a cam program that can pocket out all of the copper, and make the board look just like the pcb program's artwork. Having a dxf file allows people to tweak all of the milling variables (depths of cut, jogs, feed rates, number of passes, pocketing, drilling, etc) in a CAM program, rather than go through the g-code by hand. Speaking of CAM programs... I want to share with all of you a FOSS program that I am excited about - HeeksCAD/HeeksCNC. It is an integrated CAD/CAM software project started by Dan Heeks. http://code.google.com/p/heekscad/ http://code.google.com/p/heekscnc/ Dan has a great blog where he shows parts he has made with HeeksCAD/CNC: http://heekscnc.blogspot.com/ The current Vol. 5, No. 3, Fall 2010 issue of Digital Machinist Magazine has an article on it. I was able to compile it from source easily on my EMC2-Ubuntu-10.04LTS system. At only 2 years old it has an incredible level of CAD and CAM functionality. I am most interested right now in its 2.5 axis and 3 axis CAM abilities. It freezes, crashes, and runs very slow at times, but heck, its only 2 years old. Several months ago I wrote the gEDA-user list about my attempts to get a dxf outline of gEDA pcb's artwork using FOSS software like inkscape and pstoedit. The goal was to get an outline of all of the traces and pads so that I could pocket route away all of the copper exactly as it looks in gerbv - using a 2.5 axis cam program. HeeksCAD/HeeksCNC has the ability to open .grb files and gives you four conversion choices: Produce trace isolation sketches Produce trace centre-line sketches Produce mirrored trace isolation sketches Produce mirrored centre-line sketches Currently, I am only able to load small .grb files or else HeeksCAD/CNC freezes. The program produces a beautiful smooth outline on the circular pads using 'G03 - Circular interpolation counterclockwise' g-codes. However, the program does not recognize the ground plane clearance outlines. It only gives the outside border of the entire ground plane rectangle. I hope that will come in the future. Please, share your thoughts on this. Thanks, Dave ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
