Now we insert a new 24 pin socket - doing a socket will make it far easier to test this part in future or to replace it next time - if needed.   Below is a picture of the bottom of the board after we soldered in the socket.  Again to keep heat to the board a minimum, I soldered in an alternating pattern from one side to another and skipped every other pin.  Then came back and did the ones that were not yet done, again alternating from one row to the other so you dont do two or three side by side which might heat stress the board more or overheat the new socket's plastic frame and allow a contact or two to shift position.

Note you can see some flux residue here, slightly yellow or brownish clear puddles around each pin - which will be cleaned off after checking connectivity.

 

And here another pic from the side for a better view
