[SOLVED] Can't see legs: Microsoldering ?

[Marco_on_the_Grassland]

In the 61-pin FPC connector (the photo attached), 30 or 31 pins are aligned face-to-face within a width of
far less than an inch, so 0.01 inch per interval of every 2 pins. The photo captures the BACKside view,
and when seen from the front or directly above, the pins remain invisible.

How can I manually solder this?

Since the "feets" are not visible, a regular soldering iron won’t suffice. Using a hot air gun at a temperature
sufficient to melt solder would unfortunately cause the housing (likely made of nylon?) to melt before the solder does.
