Panelization

Hi guys,

This is about panelization. If I send the attached gerbers [attachment=2], will I get a board that looks like the attached render?
[attachment=1]

My desired outline (including internal cutouts) is in the GKO gerber file. I'm concerned because on the about page it says "Multiple outlines: if you include multiple board outlines in your file, the indlustry standard dictates that the SMALLEST OUTLINE will be used."

Since my cutouts are defined in the GKO layer as well, technically speaking I do have multiple board outlines so will just the cutout be fabricated?
[attachment=0]

If not in the GKO layer, in what layer are the cutouts specified?

Thanks in advance!

Here is the GKO from my last panelised order.


And here is what the result is.


So in other words, yes routed slots on the GKO is how it's done.

Note that this is only supported for the 2 layer boards, 4 layer boards do not support this, as per the Dirty PCBs specs.

Perfect, thanks bunches! From the photo it looks like the mouse bite holes and some (mounting) holes are non plated. How did you manage that? Tenting or two separate drill files?

No all the holes are plated, they just don't have any annular rings.  I don't think non-plated holes would be possible in a dirtypcb.

You can see on your own picture that the mounting holes and mouse bites are non-plated. All holes that are not covered by copper on the top and/or bottom layer are non-plated.

Actually on closer inspection, you are right in this instance

But here is another board, produced by dirtypcbs, using the exact same method of gerber and drill production, and as you can see the bites and mounting holes were plated in this case.

So in other words, it probably depends on what the human at the layup CAD station decides on the day. These are DirtyPCBs after all, you get what you're given.

Fair enough, thanks again. I will post what happens to mine.

I've had similar experience.
I've had probably half a dozen boards designs from DirtyPCB's now.

I have had some come back with plating on the NPT holes, some without.

I'm guessing that depending on which board house they actually go to, or the whim of whoever processes the files.

Presumably to make a mix of plated and NPT requires two drilling operations. I guess if they cannot see a reason why plating the holes is a problem, they take the opportunity to save an operation. In all cases I've submitted two drill files, separate for NPT and through plated.

Same with B side silkscreen. In some cases they merge the front and rear screen onto the front, sometimes omit the rear screen entirely, sometimes do exactly as requested.

In no case has this affected the board functionality, but it is marginally irritating.

If the board house is not going to do the backside silk screen, it would be nice to know ahead, as they do not always do a good job of merging the front and back screen.

One board has come back with licence logo (from the back of the board) half under the silk screen for a connector placement on the front of the board.
