[sdiy] There is no fun analogue chips anymore!

I would say that it's not for really fixing mistakes. And myself being
over 50 I find I do make 'mistakes'.

One technique to solder fine pitch chips (0.02) is to put more solder
than you need down on the pins. This results in numerous solder bridges.
Then you take a strand of solder wick and place it alone the rows of
pins. Next take a hot iron and run it across the solder wick soaking up
the extra solder and removing the bridges. Now if you're really, really
good at soldering you won't have this problem. But 0.02 pitch pins are
pretty close together.
