Hi,
Quick newbie soldering question. I need to solder some wires to pins
on an SOIC package. I've never soldered something with this small of
pin spacing. Is there a trick for first tacking down the wire to the
pin before you solder so that it stays in place? Thanks for any tips

I used to do it all the time when SMD parts first came out. Invert
the chip and anchor it to a piece of blank PCB with a dob of hot-melt
glue. Then tin the wire and the SMD leg, touch the two together, then
reflow it with just a touch of the iron. Takes longer to write than
do!

One slight thing to remember though. When the chip has been placed on the
board upside down, in BluTack or whatever, the pin numbering is back to
front. Oh how many times have I caught myself out on that one ... !!
