Re: [PEDA] Ground Planes

Be careful with planes. I made a pallet of 2 boards, and two of the planes changed nets. If I didn't catch it reviewing the gerbers, BOOM! Instant shorts. Sean James PCB Designer Telecast Fiber Systems, Inc. 102 Grove Street Worcester, MA 01605 (TEL) 508.754.4858 x33 (FAX) 413.541.6170 -

Re: [PEDA] Design Rules

The best and quickest way I have addressed this problem is to use mid layer 30, I place a courtyard around the component just outside the pads. I use a .5mm grid, it is an electrical trace now you can use the DRC to keep your spacing between your pads and overlay. The only draw back is

[PEDA] Multisheet Problems Updates etc.

OK Here is the scenario, I ran through this today. Hopefully I have described it clearly enough. I am running 99SE, SP6 on WIN98 Second Ed. Using the Database structure. Create 3 footprints called KP1, KP2, KP3 that could be used for this part in a library, Create a part for a contact pattern

Re: [PEDA] Multisheet Problems Updates etc.

I haven't read all the other replies so forgive me if I repeat someone else's fix. It sounds like you are editing your schematic lib each time to get the new footprint into the footprint attribute of schematic symbol KEY. You should be able to use the footprint pulldown and select the alternate

Re: [PEDA] Multisheet Problems Updates etc.

Peter, Thanks very much, I understand you can put anything you want in there for a footprint, I just would like the system to update what IS there and use it, without any extra work involved. I just used the 3 footprints for the example of what I was trying to accomplish. Like was stated and
