[PEDA] Export & import DXF drawings.

Hi all, I'm preparing some mechanical drawings in Protel so that a plastic mold designer can have a reference for items on one of my PCBs. I'm exporting Metric .DXF drawing. To test, I re-import the .DXF on a new PCB and find that some border lines are completely in the wrong place. Is

Re: [PEDA] Export & import DXF drawings.

Hi Brian, I would guess, the import is messing up. To make sure, you could (or maybe should) try to import the generated DXF-files in Camtastic. That will give you more certainty about your DXF's. When you generate DXF in Protel, the file contains everything on all layers, even if you have hidden

Re: [PEDA] gerbers from a scan ??

hello, this has been enlightening. i really appreciate everyone's post here. let me repeat that i'm not the one who's actually supposed to perform this operation. another facility here on base already does it. but it is my job to make sure that we get good work out of them for our boards, and

Re: [PEDA] gerbers from a scan ??

thanks clive, thats an interesting idea of using a transparency. the only problem i'd have with that is moving around and doing different parts of the board... i find myself zooming in even on a 6x6 board until it doesn't all fit on the screen. i didn't state my post very clearly... another

Re: [PEDA] PCB RF Inductors

Hello Francisco, Hewlett Packard (Agilent) has a freeware program on there web site for calculating spiral inductors, as well as certain microwave features. The program is DOS based, but it works very well. It is called AppCAD. I don't recall the exact URL, but I'm sure you can find it if you perf

Francisco, I found the web site for the AppCAD software for calculation of spiral inductors: http://www.semiconductor.agilent.com/cgi-bin/morpheus/home/home.jsp?mktSeg=W ireless&pSection=Wireless&subSection=Wireless Enjoy! Mark Richards CAD Designer ON Semiconductor Phone: 602.244.7267 Fax: 602

Re: [PEDA] PCB RF Inductors

Sorry but Appcad 2.0 doesn't calculate spiral inductors or any kind of inductors. It does calculate microstrip, stripline, slabline, etc but not filters, inductors etc. Best Regards, Matt Tudor, MSEE- RF Design & Consulting Gigahertz Electronics http://www.gigahertzelectronics.com -Original

Re: [PEDA] PCB RF Inductors

there's a new appcad version out (v2.5) which is not posted yet on the agilent website but IS posted for download on the appcad website at: http://www.hp.woodshot.com/ this however does NOT include spiral inductors. If you go down the page and download the old "classic" version that is the one wit

Re: [PEDA] PCB RF Inductors

Yes, sorry for the confusion. I was referring to the "classic" DOS version of AppCAD as being capable of calculating spiral inductors. Regards, Mark Richards CAD Designer ON Semiconductor Phone: 602.244.7267 Fax: 602.244.6716 Pager: 866.208.9913 Cell: 480.236.1566 - Original Message - F

[PEDA] TO-3 footprint question

Hello everyone: I have created a footprint for a TO-3 NPN transistor. The TO-3 can as you may be aware has two mounting holes, in my case these two mounting holes are attached to the collector of the transistor. I have a pad for each mounting hole which I have labelled pad 3 and pad 4. Now when

[PEDA] Loop removal deletes vias in manual route?

I have a board that was mostly auto-routed. I'm finishing it up, and find that if I have "automatically remove loops" checked, when I finish manually routing a net (right-clicking once), any vias I put down in the process are deleted! If I turn OFF loop removal, the vias remain. The problem occ

Great news, Importing the .DXF generated from Protel into Camtastic generates a fatal exception error. Brian Guralnick - Original Message - From: "Ian Wilson" <[EMAIL PROTECTED]> To: "Protel EDA Forum" <[EMAIL PROTECTED]> Sent: Monday, October 22, 2001 7:13 AM Subject:

Re: [PEDA] TO-3 footprint question

Daniel, We have had this exact problem on a TO-3 device as well as a couple of similar devices. The easiest way we found to get around it was on the schematic symbol to place the pins (in your case pins 3 and 4) on top of each other. What this does is place a junction on your schematic, this is v
