:: Copper is so much softer than steel that it will cut very easily :: with the knife. Many moons ago (like the 80's) there was a company who sold sticky backed copper foil sheet. It was designed for the hobbyist (hobbiest ), one laid the PCB pattern over it and then 'knifed' out with a scalpel the unwanted copper and then peeled off the protective backing paper and slapped it onto a hard something or other of your choice - it was about 1.5 mm thick including it's semi rigid backing. It was advertised in the original ETI magazine by a company who also were big on wire wrapping equipment. End of useless thoughts for the day :) Colin -- cdb, colin@btech-online.co.uk on 24/06/2009 Web presence: www.btech-online.co.uk Hosted by: www.1and1.co.uk/?k_id=7988359 -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
