I too have a project going to pemnuts. Please cc me on this topic. -Rosebud We have a member who has submitted the following inquiry. Any information is greatly appreciated: "I would like to get any information that you have to offer concerning broach type pemnut fasteners in FR4 material. Normally in our designs we try not to use pemnuts in multilayer boards because of the damage they can do to internal layers. We have a recent design that does use pemnuts and would like to know of any concerns there might be, especially any spacing requirement in internal layers. "I would appreciate any adive you can give me on this concern." Thanks for your help. **************************************** Lisa M.
