Hello PCBMan,

The workaround for decreasing the layers was very good that was really helpful.

But i have a concern here if suppose we have by mistake clicked the Maximum number of layers and they have gone from 8 layers to 256layers.

Than what will be the workaround to bring it back?

Thank you
Kumar

Hello Pcbman
The pads version which i am using is Pads2007.

I had problem last time that by mistake i clicked the Increasing Layer mode button and I was not able to go back because when the degin went for verification it was rasised as issue. This board was 14 layer board.


Max Layers
Opens the Increase Maximum Layer Number dialog box.

Tip: When you change to increased layer mode, layer numbers for all nonelectric layers increase by 100.

Thanks
kumar

Hello !

I used the pwrdemoa file.

This is the ascii file (with 4 layers) :

!PADS-POWERPCB-V2007.0-MILS! DESIGN DATABASE ASCII FILE 1.0
*PCB* GENERAL PARAMETERS OF THE PCB DESIGN

UNITS 0 2=Inches 1=Metric 0=Mils
USERGRID 25 25 Space between USER grid points

LAYERPAIR 1 4 Layer pair used to route connection
VIAMODE T Type of via to use when routing between layers

and now the file modified :

Import this file in Pads Layout. Go to [Setup] and [Layer Definition] and the pcb has only 2 layers. The 2 CAM Plane are deleted.

Re: PADS Tutorials

Hi pcbman,

I am new in PADS and to learn more I install a PADS demo. My problem now is that I can't view any of the sample projects. Could you help me with this? Thanks.

Re: PADS Tutorials

Hi,

Select [ File ] and [ Open ] commands then try to open pwrdemoa or preview file.

Re: PADS Tutorials

Hi all,
Do you know how to limit the number of via when using pads' auto router? Thanks..
