heat within the same unit, and the higher temperature of the chip, all of
the hot air machine are the same. While welding small size chips, use
small air nozzle, can turn down the wind speed via volume control knob,
this will decrease the probability of chip burst.
Another method
：
Appropriately increase the distance of the air nozzle to
chip, about 1-2mm.
1.775CPU Welding
The distribution of 775 PCB copper foil is not a even, the outboard 1/2
are ground wire and power supply copper foil, the inboard 1/2 are all
signal lines. According to our test, the maximum difference in
temperature can reach to 20
℃
between 775CPU and PCB copper foil.
because lots of ground wires and power supply copper foil heat to PCB's
other position.

add welding directly(needn’t desoldering),but must use liquid solder
paste.
When welding 775, please remove the metal cover of the new socket.
Choose appropriate air nozzle, select the same size air nozzle of
775plastic interior casing
When welding, make sure the jig can fixture 775 socket flattening, and
adjust the bottom air nozzle repeatedly, to ensure the 775 PCB is
