I've been tearing some old PCBs up so I can build a nice collection of transistors and caps for myself, but the problem is I haven't figured out how I'm going to pull them off the PCB without cutting the legs off. For some reason the solder is very strong and won't melt. I even took a propane blow torch to a PCB (for test) and the board caught on fire without melting the solder (the components melted too). Is there a clever way of getting them off, or should I just use a Dremel to grind off the solder (is it even solder?) and pull them out?
