Outline cut?

Hi

My board outline cut is not according to the Gerber dimension layer? The board was cut too large, on each side. It look like they don’t use the dimension layer at all.

I have uses other board houses before and my board was always cut according to my dimension layer.

Is there some problem using dimension layer at BatchPCB?

You can’t depend on it, you need to check the supplier’s requirements. I never use a dimension layer when ordering boards, the Pulsonix software I use has a board outline created as a through-board shape that appears on all layers by default.

Hi

Don’t understand, because the dimension layer is the outline cut marker!

I normally just supply the board house with Gerber files, and they know if there are a dimension layer, that mean they cut the board according to this layer!

How do BatchPCB cut the board???

They actually state that the best method is to put the outline on an outline layer or the silk screen layer, although it can be on a copper layer. They say that the dimension layer should be combined with the top copper layer, if it is used. You should have checked.

Hi

Thanks for helping:-)

I have now looked at http://batchpcb.com/index.php/Faq#How%2 … my%20board

I can see that the outline must be 8 mil tick, I only supply a outline with 0 mil track, can this be my problem???

Probably.

I don't think so. A 0 mil outline in my top copper worked well for me. This included two radiused corners.

A dimension layer on its own isn’t sufficient, though.

When you run the CAM processor, your dimension layer must be processed as the top copper layer or the top silk screen layer. It needs to leave a visible line on the finished boards so they can route along it.

No way they routinely route by eye.

As long as you make your dimension layer in the top copper or the top silk, it should come back the way you wanted it to. If you have anymore questions email me at Support@batchpcb.com.
