my board is always small and thin, I use scisors, accurate and handy. But I see a hand saw is good enough for cut thick and middle size pcb board. Wet tile diamond cutter is good, but I feel I got too much machine just for pcb: a spicified laser printer, a set of tool to do clean, a contant T laminator, a contant T etching tank, a drill table, a reflow oven, a set of chemicals. Cutting should be simplized. Actually I have a table saw for cutting Al heat sink and can be used for pcb when they are big and thick. ----- Original Message ----- From: "Howard Winter" To: "Microcontroller discussion list - Public."
