I use machine pin sockets, and suggest you do as well. Single or dual
wipe types don't age gracefully,especially the low cost ones. As has
been said previously, if the plate through holes were not damaged
removing the old IC's then proper heat and solder will wick up through
the hole. Another reason I like machine pin sockets are the legs tend
to be a bit longer. I can lift the socket off the board slightly and
get access to the top side of the pin, and solder directly onto the
top pad if needed.

I'm repairing a TZ opto board and replacing the LM339 chips. I've removed
the chips cleanly and I have IC sockets to solder to the board. The board
is 2-sided with contact pads above and below the board. What is the best
way to solder the socket to the board? I can't reach the top side pins or
pads when the socket is inserted. I could dab some solder to the pads
and/or pins before inserting the socket, but then I'm afraid it will keep
the socket from seating firmly on the board. I only have a normal soldering
iron (not one that can heat all socket pins at the same time).
Can I just solder the bottom pins and hope for firm contact and/or solder
flow to the top pads? Do I need to buy an IC soldering tip?
Thanks in advance for your help.
