I want to make a minus 400vdc supply for my grounded screen QRO PA. I
have iron on resist for masking, for solder masking silk screening and PCB etching I'd like to make it look professional. The Solder Masking Iron on is blue and can be used to etch and silk screen I have 5 sheets of 8.5X11. I have PCB material and ferric chloride I thought PCB123 had schematic layouts that went to PCB layouts so I could just print that on clear mylar on my printer and expose it to the iron on resist. I could do every thing by hand then I need a drafting table. Anybody have a link to a good tutorial? I got laptop wit 32bit XP pro and an HP printer |

I got laptop wit 32bit XP pro and an HP printer I haven't used PCB123 but I have used ExpressPCB which is similar. The purpose of these products is to sell PC boards made by the company that provides the software. Since this is the case, there is no provision (at least in ExpressPCB) to print a layout in a way that can be used to etch a board. Also, at least for ExpressPCB, the NRE is way too expensive to have one board made for home use. If you find these things to not be true for PCB123, please let us know; it would be welcome news. Another thing that I haven't done but have heard is that clear mylar isn't a good medium for making masks; the ink/toner won't go on thickly enough to be opaque. Vellum is a better choice.

Well then, when I send in the files they need to produce the PCB how will I know it's going to come out right, wait unless the software shows me a layout of the PCB on my monitor and I just do a print screen and photoshop it?
A costumer would be not so bright to spend hundreds of USD on a bunch of PCB's that don't come out right. PCB123's minimum cost is $109 for 2pcs of 9 square inch board. You must be from a third world backwater country if you think that is a high price. |

Otherwise they would just let you produce Gerber files from the tool. Why not use a good, open source tool like FreePCB? That is what I recommend. Rick |

You're supposed to be good enough to look at the layout on the screen and know. The whole point of the rapid-turn PCB houses is that they make you a board so that you don't have to. A costumer would be not so bright to spend hundreds of USD on a bunch of PCB's that don't come out right. PCB123's minimum cost is $109 for 2pcs of 9 square inch board. You must be from a third world backwater country if you think that is a high price. That's a much higher price than BatchPCB, which charges $2.50/sqin + $10/ order. $109/board is too much for my hobby budget, although I routinely pay that much for professional stuff. -- My liberal friends think I'm a conservative kook.

Rick I use Eagle, but I started before the open-source tools got good enough to be real. They have a limited-size free (but not open source) version. -- My liberal friends think I'm a conservative kook. My conservative friends think I'm a liberal kook.

ExpressPCB is great if you need a quick prototype, and, if it works out, you can get Gerbers to go into production. The software is very easy to use; hardly any learning curve at all. It's just not appropriate for hobby projects. I used it when laying out the board myself was quicker than writing instructions for our regular layout person. They also include a schematic capture program which is equally easy to use and, if all you need is a schematic, is fine. It's made for Windows but I'm using it under Linux with the aid of Wine (a popular Windows emulator). -- Jim Mueller To get my real email address, replace wrongname with dadoheadman.

Yep.. $109 seems a bit steep, unless you need them really fast. Oshpark charges $5/sqin for 3pcs, for sharp looking boards. FR4 .063" 2-layers 1oz copper. purple boards, gold flashed. About a 12-14 day turnaround. I think they are made in the US. They also do 4 layer boards for $10/sqin. Thre are several Chinese shops that will do 10pcs of 5x5cm boards for ~$10, larger sizes for a bit more. About a month turnaround. Seeed Studio, and a couple of others. Lets see.. for a 9sqin board.. PCB123 $109/2 = $54.50 per board BatchPCB 9sqin x $2.50 = $22.50 per board +$10 order = $32.50 for first board $55 for 2 boards. Oshpark 9sqin x $5 = $45. $45/3 = $15 per board So PCB123 is ~2x the price of BatchPCB, and 3x the price of Oshpark. -- -- Welcome My Son, Welcome To The Machine -- Bob Vaughan | | AF6RR | P.O.
