It's a good idea to use the pre-coated PCB material fairly soon after buying it, as the shelf-life is limited. I find I get rather poor results when using stock much older than about six months. I tend to accumulate a lot of odd-sized pieces of unknown vintage, so I need some sort of FIFO technique. Leon -- Leon Heller, G1HSM leon_heller@... http://www.geocities.com/leon_heller
