Re: [Kicad-developers] Additional Patch for via properties dialog (2)

To clarify, I agree fully that critical functionality should be core. Extra functionality could be available via an exposed scripting interface, which I suppose is already available via the existing python framework. On 23 Aug 2017 14:55, "Wayne Stambaugh" wrote: > On

To assist compilation of a set of rules, we might be able to use this link to my effortson loading/saving an Eagle DRU file. I've listed all the settings saved by the Eagledesign rule check dialog, and annotated the output file. I list the equivalent DRU keywordwith its associated dialog entry

I have experience in python DRCs and have a background in ASIC layout software and Design Rule Checks as well as a healthy experience in GIS and layer manipulation.. I have started KiPadCheck exactly to fill in some missing (IMHO) DRC checks. It might be a good as a base for further

Re: [Kicad-developers] Additional Patch for via properties dialog (2)

Something I have been considering for a while - instead of hard coding complex DRC rules into base code, what if we developed a DRC API and write the rules in Python? Each rule could be a separate python file (similar to how footprint wizards are done). Users could enable/disable each DRC and

If you're looking for good DFM manuals, check out protoexpress, otherwise known as Sierra Circuits. They're a professional board house in the USA with simple to complex board design support including high speed interfaces, uvias, etc. On Tue, Aug 22, 2017 at 2:33 PM, Thomas Langås

Re: [Kicad-developers] Additional Patch for via properties dialog (2)

I have created KiPadCheck as a post-layout DRC addition to KiCad. It has some checks related to pads, vias, drill, silkscreen, paste, and mask that address some shortcomings in KiCad DRC. I have also researched Eagle's DRC and they allow a fairly wide range of specifications for layers, vias

Hi! Maybe, some of these HDI Design Guides + documents are useful: http://www.we-online.com/web/de/index.php/download/media/04_leiterplatte/2011_2/relaunch/produkte_5/microvia_hdi/141030_DesignGuide_HDI_1_1.pdf Page 8 gives quite a good overview of what's possible - at least!

I second this. Working in a Research Institute I can assure you, that very often there are circuit boards with "interesting" stackups and via configurations... These boards are not produced by quick-turn factories like eurocircuits but companies such as ILFA or Optiprint. It would be unwise

Re: [Kicad-developers] Additional Patch for via properties dialog (2)

Manufacturing techniques vary between manufacturers and continuously evolve. Why would kicad limit itself to what eurocircuits can do? They have optimized their process for quick turn prototyping and while they document their process nicely, they are probably not a good reference for what

Oh I did not realize that gmail does not reply to the mailing list, but to you directly. I know how the progress of creating boards work. I know that you can only have symmetrical stackups. What I don't know is why KiCad limits micro-vias to outer to first inner layer only. To know where

Hi, the last patch for this function was not correct I am sorry. This patch gives the correct functionality to notify the user when die via size is smaller than the minimum size given in the net class. Cheers From 07756c6c7d28aac83cf9ee7b0e087c8b6b09bd01 Mon Sep 17 00:00:00 2001 From: Bastian
