offset solder mask from net/trace/cline

FrancisFogarty

Hi Guys, 

im just wondering is it possible to assign a soldermask area to be offset from a net or put another way is it possible to assign to a net/trace a soldermask.

see i have curved lines and i need a soldermask area to prevent soldermask been put onto the trace/clines. see attached images of my board.

All help very welcome.Thanks 

 Regards

    Theres a free app available from the OrCAD Capture Marketplace called Graseware ClineRouteKeepout that will create a route keepout area based on the clines. Once that's been used you can zcopy the shapes to the soldermask layer. Go to:-

    Hi Steve, 

    i have tried the using the tool Graseware  ClineRouteKeepout its a handy tool. but when  i zcopy the route keepout shape to the soldermask top layer it doesnt create soldermask over the actual traces themselves only over the clearance. Any ideas?

    Regards

    The tool makes a route keepout that is larger than the track by the amount you specify. When you zcopy that shape to a soldermask layer use the contract option in the Options window to make the shape the same size as the track again.
