RE: [N8VEM-S100:5157] PCB Via Counts

Way overpriced IMHO, The PCBCart boards are about $13-$18 each and excellent quality. They have done 100’s of boards for us by now, see no reason to change

Don,

I suggested OSHpark because of the quality of PCB they produce. They aren't as cheap as some, but for boards of this type, the quality is worth paying for, for boards of this complexity, IMO.

It would be interesting, though, to get a board made by the various fabs that we all use, and do a direct comparison, to see where it is worth spending money.

I also really like OSHpark's customer service.

$30 qty 100 seems a bit over priced.

Try Imagineering (PCBnet.com). They did my FPMini qty 75 for $12 per unit. No need for silkscreen on bottom.

Talk to Hasnain (847)806-0003. US company based in IL. Tell her I sent ya.

Sorry for the long delay, but here's what I heard. OSHpark could do the 80386 board for $30, for quantity 100, each, including hard gold contacts and beveling.

They did say that this sort of thing isn't their usual order, but that they liked the project quite a bit.

So, they're up for the work, if anyone wants to use them. Don't mind the fact that the silkscreen on the back of the board is backwards, OSHpark requires some kind of silk on both sides, and I didn't want to make a new one, so I just re-used the front.

Alex the files are generated with kiCAD. I’m attaching it here.
The files were sent to http://www.pcbcart.com/ not all the files are actually used by them they were just pumped out by KiCad

John,

Sorry I couldn't respond sooner. I've been caught up in a machining project for the past few days.

The PCB archive you posted has a naming scheme that I'm not familiar with. Can you send me a link that explains what the various files are? Some of them, I can guess, but I've really only worked with OSHpark, and their scheme is:

boardname.GTL Top Layer
boardname.GBL Bottom Layer
boardname.GTS Top Soldermask
boardname.GBS Bottom Soldermask
boardname.GTO Top Silkscreen
boardname.GBO Bottom Silkscreen
boardname.GKO Board Outline
boardname.G2L only if you're uploading a four layer board
boardname.G3L only if you're uploading a four layer board
boardname.XLN Drills

Thanks!

John,
I believe that they will do gold fingers, and I don't think there is an additional charge for them. However, since I haven't done it, I don't know, for sure.
If you want to send me an example set of Gerbers and drills, I'll request a quote, and find out.

If so what cost per board

I've been using a manufacturer here in the USA (IL).
They have waived setup fee for me a couple times and work hard at being
competitive.

75 boards with gold fingers, 10 days @ about $12 a board.
Check them out. They are good folks.
