Finally got my Hakko 808 and am very happy with it - great build quality and I was able to desolder a bunch of chips easily and quickly. I would happily recommend it to anyone wanting a desolderer. But I wanted to ask what temperature setting people use it at. You can set it between 380 and 480C (715-895F) but the dial uses the numbers 1 to 5, not the actual temperature.
I'm going to be doing a couple of power supply rebuilds on Williams boards and I tested it on a junk Williams board at the 2 setting (probably around 400C). The solder started to liquify in about a second, so would that be about right? I didn't have any problems with pads lifting up, but I note that at this setting it's higher than the maximum temperature of the Aoyue desoldering station which I was looking at. It's also higher than the 350C temperature that a lot of people recommended for soldering.
Is it soldering practice to make one of the joints on a chip more solid than the rest? There always seems to be one at the end of a chip that is much harder to clear than the rest. Or is that just some variant of Murphy's law, that the last joint will always be a bugger?
Thanks, Dominic
