Please log in for more thread options Hello, I just finished creating a circuit, it's a drum machine, but I've done the whole thing on a solderless breadboard. I was wondering if anybody could give me any tips on how I could go about transferring my design onto a PCB. If anyone could reccomend any software or such that is good for this? I have a copy of PSPICE, but I'm not sure if that's mainly for simulations. I've seen the "do it yourself" kits with the photo-resist chemicals and everything, but that seems potentially messy and complicated. I was wondering if anyone was familiar with the places that you send the schematic to and then they mail you your PCB? Thanks Joshua | |||||||||||||||||||||||||

The process works quite well, it costs way less to have a few boards popped out than having a technician build one from scratch, and you have a 'real' board. But you still have to do the layout with a PCB layout tool, and that's not trivial if you haven't done it before. If I have a circuit that is working right on a breadboard, and I want to make a one-off permanent circuit, and I don't care to make it smaller, I hie myself down to Radio Shack and buy one of those PCBs that has the same hole and solder pattern as a breadboard, and I transfer it -- wires and all -- to the PCB just exactly the way it was on the breadboard. This is in the US -- I'm not sure if you can get those convenient little PCBs anywhere else. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com Posting from Google?

I'd second the motion that the easiest thing to do would be to use the Radio Shack perfboard (Model: 276-170, #3.29 ea) and just transfer over directly. But everyone has a yen to try making an etched board at leat once. Hey, get it out of your system -- it's not too expensive anymore, if waiting a while for board turnaround is OK with you. Try Express PCB. They've got free proprietary CAD software, and have a starter deal where you can get three 2.5" x 3.8" boards made for just $51. You might be amazed what can actually fit on a board that size. http://www.expresspcb.com/index.htm Many swear by them. Many swear at them. They do go to some lengths to make it easy for newbies, and engineering students doing senior projects. Just remember their software locks you in to buying from them or redoing the board in another CAD package -- the files are incompatible with other CAD software. Good luck Chris | |||||||||||||||||||||||||

AutoCAD has applications for electronic drawing and with some work CADkey is also available to draw electronic design. Using standard Electronic shop practices you can adapt any CAD software drawings as circuit board drawings. How do you thing electronic drawings are made? By hand? haw haw...
