Elongated hole

Former Member

Hi,

I'm designing a circuit that requires a long thin slot (6x1 mm) in a pad for

a relay terminal, has anyone come up with a solution for this?

 

Thanks,

Rob

    Search for slot in user and in support for detailed threads on the

    subject. The short answer. Use the milling layer and contact your board

    house.

    A warning to this issue if the hole is plated: (a useful warning can not be

    repeated too often)

    If you use milling layer on plated holes, take care if you use fill's or

    power layers somewhere between upper and lower layer. If you have that,

    either make sure it doesnt fill under the plating, or tell the manufacturer

    to make sure the plating doesnt make shorts.

    By always giving the manufacturer a netlist with test points (like

    ipc-d-356), the manufacturer will find problems like that before he starts

    manufacturing.
