hello all,

i would just like some info on tools used to repair mobile phones.



ive been looking around and going to purchase some repair equipment consisting of : solder iron, hot air gun, solder tweezers.


i know i can buy all this as a 3 in 1 station.

on a few sites i have seen " bga multi function repair platform"
what is this used for????

also i have seen a dual vacum pens.
are these to lift up componets while soldering on and off, so we have a secure grip on the component?
also this equipemnt ie, dual vacums, do both pens have differnt uses? if so what are they?

also what other equpiment would i need to do repairs for mobilephones. i have some soldering knowledge.
