Re: PADS, ASCII output question: Scale factor?

Joerg,
There is a way to interpret that, but I use an unsupported script under VB scripts in Layout to make my X-Y ***. Some 3rd party programs that some assemblers use can directly read a PADS ASCII file, that is why they asked for that, but apparently yours cannot so use the built in script under VB scripts.

BTW I thought you were on the PADS ListServer as well. Probably get better answers there than here.

Hello Folks,

We weren't able to sort this out. The layouter said this is the usual file that SMT assemblers use to program their pick&place machines but the assembler said they can't use it since the scale factor or data format for the coordinates is unknown. PADS was set to the American dimensioning of "mils" (1/1000th of an inch). Contacting Mentor resulted in no help. Here is one example from the ASCII file:

R75.2 R66.2
-190690500 289179000 1 381000 1024 TEARDROP N 90 90
-190690500 287274000 31 381000 512 TEARDROP P 90 90

What does "-190690500 289179000" mean in terms of mils, or millimeter?
