Re: [PEDA] gold plating?
John, After talking with the board house, I've decided to just plate the whole thing in hard gold. It turned out to be much cheaper than selectively plating one component. The only reason I hadn't planned to gold plate the whole thing was cost - wrong again! BTW for all who asked, the component is a six land circular pattern to mate with a gold POGO pin connector.

Is there a way to specify this? Bob You could probably specify this on a spare mechanical layer and add it to the top layer ident to make sure it gets noticed. On the print preview you could merge these layers (in colour) to give a graphical view of the where, why, when. The plating, is it going to be immersion or hard gold? Both will need masking of the rest of the board but because of the electrical requirements of hard gold you might need to add some way of coupling the nets together electrically (same idea as edge connector). Any reason the board cannot be completely immersion gold? (if this one part needs to be hard gold the anser does not matter as same issues apply).

Re: [PEDA] gold plating?
You specify it the same way you specify any special requirement. 1. Call your fab and ask them what documentation they would like to see for selective plating. 2. Put a note on the drill drawing referring to an outline box, circle, etc. on the drill drawing that identifies the pads to be selectively plated. Call out the desired plating thicknesses for nickle and gold in the note. 3. If necessary, outline the precise selective plating area on a separate mechanical layer with a note specifying the nickle and gold thicknesses.

Re: [PEDA] gold plating?
Dear Sir, Specify the location on your fabrication drawing and the PC board shop will tape off the unwanted area. Mind you its less expensive just to finish the whole board with the immersion gold.

Getting whole board plated will probably come out cheaper. Contact your board house directly for info on what they require. All depends on their capabilities.

Re: [PEDA] gold plating?
Manually there is always a way, actually in this instance it's the only way I can come up with, sounds like a very special part - Original Message - From: "bob stephens" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, August 27, 2004 12:44 PM Subject: [PEDA] gold plating? > I've just run across a problem that has never come up before.
