Jdm-050 replace tactile switch smd buttom share

[zis2104]

Basically I bought 3 broken controllers and repaired 2, but the last one is almost all fixed except the share button has been removed, how do I solder it for a new one? How many degrees do I have to heat it up?

 There is no magic temperature that will just work. Using solder paste and a hot air setup would work best. Preheating the board will help, but you'll just have to find the balance there between the solder reflowing and not nuking the plastic of the new switch.

Rip the dome out of an existing tactile button and use clear tape to stick it is the easiest method because those small points are really hard to solder
