I was about to put together an array of 19 white Nichia leds when I read the discussion on heat-sinking awhile back...and the project has been sitting ever since. I have had no cash to buy any copper sheeting, and am not sure how I would drill all those holes accurately anyway; I was just using perfboard. So the question is, if I just solder them up in the perfboard, will they overheat if I keep the current down to 20mA?
