Is it possible to have mounting holes drilled, but without any pads? It seems my only option right now is to just add the minimal .043 inch pad around the...
I've been wondering about this issue as well. I need non-plated holes on some of my boards for mechanical alignment (i.e. tooling holes) and am concerned I...
In fact, i even put the holes w/minimal pads, and am now being flagged by the "Group to make Component" feature that the mounting holes are not numbered....
I've successfully used the smallest pad possible for the hole size on several boards. To make the 'group to make component' nag-o-matic be quiet, I assign it a...
... see no ... I don't think it's the pad that's the issue, I think it may be the plating inside the hole. If the hole is being used as a fiducial for ...
Well mr. nit I hope you realize that nobody here is dumb enough to buy goods or services from a spammer. Spammers are dishonest by their very nature. Doing...
Hi there! Can anyone suggest how to make our own custom pads of different shapes? I have no option than using either the round or square ones available from...
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...
Colleagues, I'm not using ExpressPCB any more – I've switched to OrCAD. My client has asked me to get some competitive quotes from three (3) different PCB...

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...
