Re: How to copy a PCB
Andy Eskelson
Hi Sudipta, and welcome.
What do you mean by "copy" a PCB Kicad is a PCB DESIGN suite, you first design the circuit, then assign the component modules, then you can start to create the PCB, laying out the tracks and so on. Once you have designed the PCB there are tools which allow you to place multiple copies of that design on a PCB. This is often used when you have a small board, and you want to have many duplicates made in order to reduce costs. This is often referred to as panellising. If you want to take an existing PCB and make a copy of that, then no Kicad is not that sort of program. I have reverse engineered a few old circuits (fairly simple stuff) in order to resurrect some old obsolete item of equipment, but I generally trace out the circuit enter than into eeschema and then go through the normal Kicad process, except that I have a old pcb that I can use as a reference when laying out the tracks.

My question is can I copy a PCB in KICAD?I get a bit nervous when I hear the word "copy". Conjures up images of stolen homework and the breaking of licenses. At the risk of making myself unpopular, and taking a different approach to the other replies, I'm wondering if you are entitled to make a copy. Whether the design is under an open license or not, there are still conditions that you have to meet in order to copy the board. If it's not an open license, you would need the permission of the board design's owner in order to copy it. If the original board has good RF properties, it's not by accident. it's because some fine engineer knew what he was doing. Copying that's not permitted doesn't reward him for his effort. Mitch. |

I have copied a job by just copying the whole directory with a new name. Or you could save the old job to a memory stick and continue your work on the old job. Richard On 13.07.2012 14:31, Richard Webb wrote: ? |

I don't know of a simple way to cut and paste between PCB projects. Doing so raises the issue of the mapping between a project netlist (from the schematic) and the resulting PCB copy, so it's not as simple as a Ctrl-C / Ctrl-V. It is possible to use a text editor and copy module sections from one .brd file to another but this doesn't solve the reference designator problem. What I would do in a similar case would be to make a "master" schematic and PCB layout project that contained the key elements and that had a good DRC/ERC check. Then copy the whole project to a new directory and make the changes there. |

Yahoo has allegedly been hacked
I've just been warned by the moderator of another Yahoo group that:
"Yahoo has recently been hacked and 450,000 accounts have had their email address AND password published in clear text. Please check your account urgently at and if yours is listed please change your password as soon as possible." I don't know how true this is, but I thought members of Kicad Users would rather be warned than get hacked. I can tell you that I didn't get any warnings when I visited the above link and I have quite a few defence mechanisms in place. Also other sites are reporting this. If anyone knows better, please say so. Regards, Robert. |

Re: Component position files in metric format possible?
Currently, the only way to do so without external processing but only using KiCAD is getting the KiCAD sources, modify pcbnew/gen_modules_placefile.cpp and change the #if 1 into #if 0 so that the unit conversion would be hardcoded to be in millimeters.

Then you'll have to compile and install the compiled KiCAD.. I understand this is not optimal, but worked perfectly for me in real product production. Hope this helps, Fabio Varesano On 07/12/2012 01:45 AM, oecherexpat wrote:

Re: Component position files in metric format possible?
Yes, I simply ran it through Libreoffice and added 2 more columns with converted positions - is's simple factor after all.

Will see how it goes. But I thought it might be possible in Kicad as it is possible to chose imperial/metric when creating Gerber files. Cheers, Heiko --- In kicad-users@..., Andy Eskelson <andyyahoo@...> wrote:

Re: Component position files in metric format possible?
Andy Eskelson
Kicad works in imperial internally, I think it's grid is 0.0001, might be
0.00001 I'm not 100% sure. So any metric output would be a simple conversion. I find it strange that a manufacturer cannot handle both formats, but if it is really that important I would write a script to do the conversion as needed.

Component position files in metric format possible?
Hi all,
Does anyone know if it is possible to have the component position file done in metric format (rather than imperial)? I am using fine-pitch connectors and my contract manufacturer mentioned that it would be easier and more accurate because their system apparently works better with metric inputs. Thanks, Heiko |

Digest only has problem. Change to one email per message. (Plain text only is my recommendation.)

Problem with new e-mail format. Since Yahoo groups changed the e-mail format, the e-mails are poorly readable. The menu and first message are fine, but all subsequent messages are a mess. Each word is on a single line like this. Example: The founder is truly a special person. Without bitterness he accepts the facts. Hope someone will help him back on Please fix this! |

How o make pcb side pads
Hi, i have two questions. One related to kicad and other to general pcb manufacture.
I want to develop a few pcb modules to be solderable on other PCBs. The pads i want to use are QFN like. Something close to these blue tooth modules. How can i place such pad on a PCB with kicad? Maybe a PTH pad placed at the corner of the board? Just to make clear, i want to make my PCB to be solderable on other PCBs.? The second question is if that kind of pad is a common feature to request from a PCB house or i will have problems with that? Thank you! Lu¨ªs Filipe Rossi

Can't select Mode footprint and mode track in Ubuntu 10.04 using ppa adamwolf
Can't select Mode footprint and mode track in Ubuntu 10.04 using ppa adamwolf and pcbnew.
A bit strange as other version of Ubuntu 11.04 seems to work fine. The icon won't stay highlighted after clicking it, and menus don't change. So I can't unstack all the components after importing them using the netlist. Any thoughts on a work around? Is there like for example keyboard short cuts? |
