Atium Designer: How to make a groove on pcb with customized depth and width

[WMY0318]

Hi I would like to make a groove on PCB, which cannot cut through the PCB, instead it should have a small depth which can be user defined. So which layer in altium designer shall I draw the groove on? and how to define its depth and width? Thanks

I hope there is no facility available in altium to mention the depth of the V-groove. Normally these things are taken care by the manucaturer & if need to specify the depth you can write a string outside the PCB design & it goes along with the gerber file. For this option you can use keep out layer.

Any mechanical layer can be used for that. But as mentioned udhay_cit, manufacture should understand what do you mean by that.

This is something that has to be communicated verbally to the fabhouse. Make a new layer with just the groove drawn on it, throw some text on it describing its desired properties. The fabhouse should know what to do, assuming they are actually capable of making the groove in the first place.

Communicated to the fab house yes - verbally - not unless it is also backed up with a drawing showing exactly what you want.

Verbal instructions are fraught with being forgotten, not passed on etc.
Do it in a drawing, supply that with the Gerbers.

Is the V-groove for de-panelisation?
If so maximum angle and minimum web left are the important criteria...

Right, you also provide clear written instructions with the files you send, in case they screw up and try to shirk the blame. But it's prudent to also give them a call beforehand so that you're sure someone there understands the instructions.
