HI Mod,

to remove CCONT with glued , i used (hakko 850) to set :

AIR : 3.5
heater: 3
if use temp. meter to test it with 2 CM, it around 260 ~280 C.,

first heat side of CCONT, till tin come out !
then continue to heat CCONT and use knife to "VERY SLOW" to pull up CCONT !

almost all glue will stay in CCONT chip, PCB have few glue only!
then make AIR to 1, heater set to 2.5, then use knife to clean glue in PCB !

then clean CCONT chip upper all tin , and you can easy remove glue as like remove a paper !

Hi.
I heard about this liqiud. But all people who bought says it is fake. Did you test it yourself? What is it name?
Thanks for attention.

Pandemonio100 · 09-26-2002, 19:51

right willy I use the same your method and work fine.

willy · 09-26-2002, 20:09

@Pandemonio100

also use squaren nozzle to heat MAD , so, it will not go over to flash rom or CCONT

Willy

Pandemonio100 · 09-26-2002, 20:23

Yes, there is however to say an important thing, to work the component BGA has to have a good hand and above all you has to understand how much air to use and how much heat for every type of component, if you succeed in understanding this the game is done.
