Chamfers on edge connectors - how ?

David Slipper All Messages By This Member #23748 I need to make a board with a PCB edge connector - I have the footprint for the pads OK - but how do I define the chamfer edge on the connector ?? Or is this a case of just telling the foundry what I want and where ??? Regards, Dave

May cost a bit more to deal with edge plating. I use Electronic Interconnect (EI) as they are very helpful. Not sure how to work with Sunstone as we use EI for production work.

Jerry Durand #23751 开云体育 It's in your fabrication notes, we have a whole block of notes on the fabrication layer.? Not saying anyone reads them, but the instructions are there.

Glenn Hamblin All Messages By This Member #23753 Hi David, You should always supply the fab with a mechanical drawing or fab drawing of your PCB. This is where you will specify the dimensions and tolerances. This drawing should also contain a drill chart with hole sizes and if they are to be plated through or not. As well as a notes section where you specify the materials used, copper weights, soldermask type and color, nomenclature (silk screen) color, finish (HASL, ENiG, etc) and for the fingers hard gold if that's what?you want. Typical thickness of Gold (Au) is 30 to 50 ui(micro-inches) over Ni 150-250 ui. Hope?this helps.
