CAN WE FIX IT? PROJECT 4 PRACTICAL REPAIRS FOR EVERYONE APRIL 2, 2016 HACKER HOTEL DATUM KLANT
REFLOW BAKE COOKIES AND BGA’S
Why do we reflow? Bad GPU’s and other chips Board connection Die-carrier connection Relatively easy replace QFN packages and other SMT stu ff
TOOLS REQUIRED AND RECOMMENDED
MY SETUP BEFORE I BOUGHT A PREHEATER
Reflow profile Preheat at 150 ℃ for 3 mins Soak at 230 for 1.5 mins Peak at 350 for 45 secs Soak at 230 for 1.5 mins Cool at 150 for 3 mins Cooldown for at least 15 minutes! Ikea FORSÅ (seriously!)
Top Tips Aluminium and Kapton tape are your friends Flux should be your BFF Reflow profile is up for experimentation Stu ff is hot!
A BIT MORE ADVANCED HOT AIR REWORK

Closing thoughts Most repairs i do are mechanical in nature and are really easy Even complex problems can always be traced back to a root cause The older, the more di ffi cult to diagnose but also the easier to repair.
