Title: Card Edge Chamfering. How to specify with PCB vendor?
Post by: LabSpokane on August 08, 2016, 12:56:37 am
I'm thinking about moving a project into a backplane arrangement.  While i realize chamfering a card edge is easy to do on my own, what's the correct way to handle it when getting a PCB manufactured?  Is this done in the Gerbers, or is it simply called out on a drawing and the PCB manufacturer adds it into their programming?

I suggest asking your supplier how they want it called out (or if they even offer it!). Everyone seems to have different ways of handling mechanical features like these.

If you are working with a Chinese fab, they call it a gold(en) finger.

Surely that refers to hard plating which may or may not involve an edge chamfer.

That one is called golden chamfered finger in Taiwan and chamfered golden finger in mainland.
