gEDA-user: Footprints!!!
Hi, I encounter some problems while using the gsch2pcb. The major problem was about the footprints. Somehow I can't get it to work. I followed all the instructions on this webpage http://geda.seul.org/wiki/geda:gsch2pcb_tutorial;. However, the computer cannot detect what is in the pcb_element file, because the strange thing is, what ever footprint which is not found in the pcb_element folder, the PCB symbol can be created whereas the footprint that is in the pcb_element folder, the PCB element shows an error that pcb_element cannot be located. The footprint i used was the package number of the product, for example this connector Molex-5045-03A. Can you tell me what should I do ? Thanks :) With Regards, Louis _ What can you do with the new Windows Live?

You insert promotion for windows software and send your text twice, so I guess you use PCB on windows. I do only use Linux. What should be clear: For PCB/gsch2pcb the footprints must exist on your computer, i.e. a file with ending .fp. You can not expect to use some funny product name and magically get the correct footprint. Look on your harddisk (I do locate -i myname for Linux), look at gedasymbols, look at John Luciani's page, ask here, or make your own footprint. Maybe one of the developers or PCB experts can understand your problem better than I.

I don't think tragesym caters for such symbols. Anyway, I submitted the problem as a bug report on sourceforge - I hope someone reads it. There seems to be little activity there. I solved the problem by drawing the symbol, rotating 90 degrees, adding the pins, and rotating back. It's only _drawing_ the symbol that causes the problems - it may be a GUI issue.

I don't think tragesym caters for such symbols. Tragesym (or djboxsym) gives you a template, i.e. all pins with right direction, numbers, label, fontsize... I take that and move pins to other position and do some graphical fine-tuning. Sometimes I only copy a similar symbol and modify it, maybe copy a few pins. Anyway, I submitted the problem as a bug report on sourceforge - I hope someone reads it. There seems to be little activity there.

And maybe you should give more details about your box, i.e. compiler-version, OS, version of GTK and other libraries...

Re: gEDA-user: Footprints!!!
I renamed the connector to Molex_5045_03A.fp as John told me, this message came out M4: can't find PCB element for footprint Molex_5045_03A.fp (value=unknown) So device M4 will not be in the layout. :) Date: Mon, 27 Apr 2009 14:39:36 -0500 From: j...@ecosensory.com To: geda-user@moria.seul.org Subject: Re: gEDA-user: Footprints!!! louis lry wrote: The footprint i used was the package number of the product, for example this connector Molex-5045-03A.

Well, if you don't tell gsch2pcb where your footprints are, how do you expect it to find them?

gEDA-user: OT: soldering QFN packages with exposed bottom pad?
Guys: Got any recommendations for how to hand-solder a QFN package that has an exposed bottom pad? At the moment, all I have is a soldering iron. Do you think I could just put a plated-through via underneath the pad, and then flow solder through that from the back side? b.g. -- Bill Gatliff b...@billgatliff.com ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
Re: gEDA-user: OT: soldering QFN packages with exposed bottom pad?
Got any recommendations for how to hand-solder a QFN package that has an exposed bottom pad? At the moment, all I have is a soldering iron. Spend $20 and buy a cheap hotplate :-) Not sure what you'd do about solder paste; perhaps put solder dots on the pcb with your iron, add flux, and reflow it. Do you think I could just put a plated-through via underneath the pad, and then flow solder through that from the back side? I've done that as well, but beware you need a pretty hefty iron to generate enough heat to melt the solder. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
Re: gEDA-user: OT: soldering QFN packages with exposed bottom pad?
I've done this, but not always with success. First, get some fine solder paste and a flux pen. When you do the layout, put a pad on the other side of the board, connect with a few vias to the part's bottom pad. Be sure to have a solder resist opening on the back side pad. Apply flux to the large pad only, on both sides of the board. Then paste the pad, both sides. Then place the part. When you heat the back with the iron, the part may want to move. It often helps to tack-solder a couple of the other pads on the QFN (farthest away from the large pad) to keep it from moving. Solder the remaining small pins last.
