It is common for solder to cover up some of the holes through solder pads on the board. Opening these holes greatly simplifies soldering.

Open the holes through the solder pads by pressing a straightened staple against the blockage while heating the same pad from the other side of the board.

A "third hand" tool (or a friend) can greatly help in this procedure.
