Hi, All: I design a fair amount of audio stuff using expressPCB. Among my favorite parts are the Analog Devices AGC amps. The old SSM2165 and SSM2166 are no...
Andrew, I use a 0.5mm pitch 30 pin socket for a tiny display I use on one of my boards. While I did have to "construct" the component's lans, it was really...
Ed, Many, many thanks! The critical info I was lacking was that there IS a SMD shape available in pad manager. I've made custom parts before, but this is the...
Glad to help, Andrew. I recently got into doing SMD boards and found that there is a lot of variation in packages even of the same type component. With a...

Hi, I'm new to ExpressPCB and this group. I'm planning to rework a hand-soldered perf-board design in SMT. Basically I'm going to integrate a Basic Stamp into...
You can certainly create the 48pin QFP. The trick is that you won't do it by drag n drop. When you place a SMT pad on the board, you can locate it's position...
Rafel, I have used the ExpressPCB Component and Pad Manager to create component pads with a 0.5mm pitch (smaller than TQFP) for a 30 pin connector. The...
Another trick that works is to set the show grid and snap to grid (from View / Options/ View tab to 0.5mm Turn snap to grid on. Close the dialog. Zoom in...
I have had excellent results in creating any component that was not included in the component library using the create option. The initial component library...

Hi! I was wondering if anyone has (or can point me to) PCI add-in card edge fingers / traces board layout please. I noticed that there is a zp file in the...
Mike, activity on this group seems to be non-existant so I would hazard a guess and say that if its not in the files directory, then no. Regards EK ... From:...

Folks, I'd like renew this request and to join it. I'm looking for DFN-8 and DFN-16. Could anyone upload it of tell me where in the group's files it is? ...
This DFN-8 was derived from Linear Tech's web site: DFN-8 The thermal pad is designated pin 9. Pad sizes should be to the drawing, but it has never been used,...
