Re: Problem uploading 4-layer boards

That's a shame - I've built most of my prototype FPGA development hardware with boards from batchpcb, and I was returning to fab new boards that incorporate bug fixes. Unfortunately, there aren't many hobby level board houses that will do shared runs like this. The closest I've seen is DorkbotPDX, b...

Problem uploading 4-layer boards

Hello, I have been trying to upload a couple of 4-layer designs, both of which are slightly tweaked/refined versions of boards I have already built using BatchPCB. In both cases, despite specifying the inner layers during upload, they came up as 2-layer boards and failed DRC. I tried going into the ...

Can you do castellated pads with BatchPCB

Is it possible to do castellated pads, which appear like a normal circular pad cut in half, with BatchPCB? These are boards that you place flat onto another board, and solder in the cup.

I learned this the hard way as well. I did a four-layer board with 6 mil trace and space, and used a connector that wouldn't fly on a two-layer board with 8 mil trace and space. Unless your board is very large, it might be worthwhile to consider 4-layer anyway. The power distribution properties are ...

Are 4-layer boards still available?

I tried placing an order for a 4-layer board, and it sat waiting for panelization for 4 days. On the 4th day, the order was cancelled, and I received a refund. I've tried emailing, but I am getting no response at all - so I don't know what the problem is. My next option is Sierra Proto Express, but ...

It seems the problem stems from the board layout not being centered at 0,0 - I moved the board to the origin, and it started giving me closer to accurate sizing information. It's now only off by a few mils.

Also, it appears the bot totally ignored the outline layer for sizing.

For the admin - the board ID is 43171. Everything seems cool except the size - it's still reporting it as 5x5

No. I fixed the overlap on an over-hanging RJ-45 connector in the first go-around by editing the component symbol. The final silk screen truncates at the board edge. The only place where something overlaps is on the mechanical layer, but that didn't get submitted. Also, it would have only added a ha...

Problem with four-layer board

I'm trying to submit a four-layer board, and I've run into a couple of problems. The first is that the top layer is showing up differently from the rest, and it is making the board size huge - it should be an 8 square in board, but instead is being shown as a 25 square in board. The layers all look ...

What is the layer order?

 by jshamlet ¦  Thu Jul 23, 2009 7:40 am ¦  Forum: BatchPCB ¦  Topic: What is the layer order? ¦  Replies: 0 ¦  Views: 1138

I am doing a 4-layer board, and I would really like the order to be top, ground, vcc, bottom. I believe that works out to assigning GTL, G1, G2, and GBL. (Makes sense, but I wanted to check) It's not critical, but the ground plane is much less cut up than the Vcc plane. Is this the correct layer ord...

I'm doing a EQFP-144 (Cyclone III, 3C16) and the bot hasn't complained yet. I haven't actually built one up yet, however.

Yep - I redid the plane layers as copper pours, and the bot now sees them correctly. This was mildly annoying, since I had a bunch of split planes, but now, at least, the report is mostly correct. (All of the layers show up correctly) Now, I just need to figure out how to get the bot to realize that...

I tried Altium, and they suggested centering the output layers on the film, as opposed to the default setting. I tried it, but the plane layers are still screwed up. Other than that, there really aren't that many buttons to mess with in the exporter. I'll try converting to normal signal layers and u...

Problem exporting Gerbers from Altium

I'm running Altium Winter 09, and I have a board that is 4.75"x2.65", and all of the gerber outputs look fine in Camtastic. It's a four layer board with interior plane layers for ground and Vcc. I setup the DRC to match the specs in the FAQ, and the board passes. Unfortunately, when I upload, the pl...

4-layer and split planes

 by jshamlet ¦  Sat May 30, 2009 1:46 pm ¦  Forum: BatchPCB ¦  Topic: 4-layer and split planes ¦  Replies: 1 ¦  Views: 1677

I'm working on a board with an FPGA and Gig-E PHY, and following the recommendations on power & ground has resulted in a fairly complex beastie of a board. It's got split planes on both power and ground - about 4 splits per plane. I would assume that all four layers can be treated as signal layers, ...
