I've tried this several times but I just seem unable to solder the new LGA socket.
I have no problem removing the old socket with broken pins, but using the same profile (or a bit hotter one) to fir the new socket results in a socket that is firmly attached to the board but just using the multimeter and checking continuity between Vcc pins (or ground pins) it is obvious the new socket is not soldered properly. I find maybe the outer pins and the next row may solder but not the inner ones and not all around the socket either
I've tried about half a dozen times now on various boards with various profiles and get the same result
I am using the technique - remove old LGA1151...
clean PCB with leaded solder ball and then braid
use paintbrush to apply this layer of Amtech 559 to the PCB
use optical alignment to set the socket position
solder
I've now come across this other method, on a very similar machine to mine, where they don't use flux, not any that it mentions anyway, and use a stencil and solder paste instead

Has anyone tried this method, and did it work?
