Cheers, Tom Hi Tom, Being so new at this, I don't even know what you mean by 'tombstone style', and it sounds like an awful lot of work to be scoring pcboard with an Xacto knife to create transmission line effects. It's really not all that difficult. Just use a ruler to guide the knife, use a sharp knife, and the strips you want to remove can usually just be pulled up in one piece (each). Or do it as Ian suggested, with sticky copper tape. As Ian wrote, keep lead lengths extremely short, like "zero." He suggested putting a piece of heavy copper wire through the board where you want to connect to the ground plane. Another way is to simply drill a hole through the board and drop an 0805-size surface mount part into the hole, and solder both ends. A 1/16" hole would work, but you'd do better to pick a size that just fits the part you want to use. Not all 0805 parts are quite the same size, but the body lengths are pretty accurate and work nicely in 1/16" thick board material. Any of the methods mentioned by Ian and myself will work well, and all are reasonably easy to implement with a bit of practice and patience. Cheers, Tom |
