A small British company is now making RF prototyping boards that have square pads on a 0.1in grid, with a continuous copper groundplane on the reverse. Every pad has an unplated hole drilled through to the groundplane, which allows good RF grounding. The board is very versatile because you can mix and match various styles of construction on the two different sides. The groundplane side can be treated as continuous copper for dead-bug and 'ugly' styles of construction, but the pre-drilled holes make it very easy to connect through to the pad-style wiring on the other side. To make insulated lead-throughs, simply remove the copper around the selected holes. On the pad side, the 0.1in grid is suitable for conventional wire-leaded devices and DIL ICs, along with many of the larger SMD packages. Smaller-pitch devices can be soldered dead-bug style on either side of the board - whichever way works better for that particular part of the circuit. <http://cgi.ebay.co.uk/RF-Matrix-PadBoard-149x114x1-6-Prototype-Circuit-B oard-/170586485860> -- 73 from Ian GM3SEK http://www.ifwtech.co.uk/g3sek ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
