What happens when a V-groove hits your copper pour

Posted on Tuesday, January 8th, 2013 in manufacturing, PCBs by DP


Panelizing multiple PCBs onto a single panel is a cost effective way of prototyping. V-groves are usually used to separate the different PCBs, making it easy to snap them off. The picture above depicts what happens when the V-grove hits a copper pour such as a ground plane.

Anyway, back to the topic. You usually want to have a copper pour on your boards, be it ground or a power plane. Sometimes it just so happens that you send your Gerbers to the PCB fab but they reply back saying the V-groove will cut the copper, is this OK? Well, in one of my prototype boards I just told them “go ahead”. This is what came back

    does seeedstudio allow v-groves?

  2. Matseng says:

    Yes and no… :-) They don’t do it as a part of their cheap fusion pcb service, but they can do almost anything as a special service if you ask them.

    Never mind the faeces hitting the fan – we have the v-groove hitting the copper pour.
    I can already imagine the blank faces if I trotted out THAT line in a conversation.

    Thanks matsing :).. a v-grove on the cheap PCB service would be great though
