Hole in stencil layer

Hello,

I have to provide a gerber file for stencil manufacturer house.

In the brd view I created a layer named "stencil" where I defined the

contour of the stencil. Then from CAM processor it's easy to add the

aperture from the cream layer(s).

 

I also need to add some hole for the SMT stencil printer.

These holes should be present only on the stencil gerber file, and not

in the PCB ones (they are outside the PCB of course).

 

Is there a convenient way to handle this?

I wouldn't create a second brd file just to add the holes...

Hello Marco,

I hope you're doing well. The easiest solution would be to draw a filled

in circle on the stencil layer. Click the circle command, set the width

to zero(this will make it fill).

Let me know if there's anything else I can do for you.

Best Regards,

Jorge Garcia

This is a good hint!

I bet I need to ask to the PCB house if they will recognize them as

holes, actually.

Hi Marco

The PCB house should not recognise the filled circle is a hole. Your

drill file specifies where holes go.

If you are sending the eagle board file and not gerbers, they may

calculate the board size as bigger because you have objects beyond the

board edges. Hence the cost of the board may go up.

That's what needs checking.

If this is true there is a way around it using assembly variants.

Make device that has a package with the filled circles on the stencil

layer and a symbol you would like for the schematic. Then make these

into simple device. Using assembly variants you essentially turn on and

off those stencil holes because you turn off the device/package when set

the assembly variant and save.

You can do all this without a user defined stencil layer. Just use the

cream layer

I will send gerber file, not the EAGLE board one.

And for stencil is a separate order, so I will upload only the stencil

layer.

If I understand correcly I need two variants. One with all components

but the stencil one, and another with only the stencil.

It might work! I'm going to give it a try.

Thanks
