    offset solder mask from net/trace/cline Reply

    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

    Fran

    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

    Fran

    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.

    Hi Steve, thanks for the reply i have attached an image of the result i get what im experienceing happening is the trace itself is actually not getting covered by soldermask when i zcopy the route keepout. it is just the offset shape area that is been covered. i have attached an image of it below hopefully you will be able to see the result. the trace is not been covered itself and the area in between contactor soldermask and sma solder mask as pointed out is not been covered as a result.

    OK - Use the cline keepout to create a route keepout on the bottom layer as well. Then zcopy this shape back to the soldermask top. The keepout on the bottom should be a better shape for you to use.

    When you run the app there's a checkbox for TOP and BOTTOM keepouts.... Pick the BOTTOM one.....

    Yes you do. Check the box next to BOTTOM (or any other layer) and a route keepout is created on that layer....
