Hi Mike,
I don't think we would need any prototypes since the board design has been proven before.

Jerry,

if you can get the file converted to gerber files, I’d spend the extra money and have them cut.

and if you can get them converted, I’ll make a few prototypes before a run is made.

Hi Guys,
I can get the boards from China for about $3 each. I have a good friend who can convert the ExpressPCB format to the Gerber format. I would have to buy 10 boards at a time. I would also have to cut the boards to size myself. I might be able to get my friend to cut them apart. Maybe we could get another group buy going. What do you guys think?

Thanks, Steve,

I guess what they say is so true, there is no such thing as a free lunch.

The pcb house I use could make those for about $5-8 a copy (100 pc lots) if they have the gerber 247 files (industry standard)

I also use a company that panelizes boards and with a small run of maybe 25 copies, the price should be about (I’m guess here!) $10-$15 a pop.

I wonder what the conversion would cost from ExpressPCB?

Then again, if you don’t have an issue, i could lay out a new pcb and bypass express all together. I’ll take a look at the schematic and see what’s going on.

I normally use a program called Circad to lay out pcbs, but this will give me an excuse to teach myself Eagle PCB Cad.

Mike,

It's a proprietary ExpressPCB format and I know of no easy way to convert to a Gerber file. ExpressPCB will do a conversion for you ...... at a price !
