Singing to the Quire here, Talk about a PITA,
I ovaled the pads on my latest PCB and pre tined all four pads (2-chip) and the PCB two.
With nothing soldered I clamp(gently with long spring clamp. Flip it over and solder the holes in the pads (SLOWLY) a tad more heat exposure but it works well. Then I flip it and solder 4-5 top pins, not soldering un-used pins. Took a couple tries but that’s the tech I’m using to hand attach each to my PCB’s 5 so far NO issues.
this is the first one,

NOTE: on the PCB order those holes are plated thru also.(called-out)
