Cum sa dai jos adezivul de pe placa Hyundai !?

[Duster]

Vreau sa va intreb cum sa dau jos adezivul din jurul procesorului de pe placa de baza din Hyundai ?
Am obtinut o solutie care merge la multe tipuri de adeziv (chinezesc BGA IC ADHESIVE REMOVER) dar nu are efect.
Alte solutii inafara de polizat ?

Multumesc in avans pentru raspunsuri.

cel mai simplu prin polizare.

<< We placed the slides in sodium ethoxide for 1/2 hour >>

I agree with Cathy, sodium ethoxide usually works well for epoxy removal.

We used to make our own by *slowly* adding sodium hydroxide pellets (one at a
time; wait until pellet is dissolved before adding another) to 100% ethanol.
A good, muddy brown color usually indicates the ethoxide is ready to use.
You won't need much, only a few microliters to cover the section on the
slide. Also, monitor carefully. The dissolution of the epoxy occurs fairly
rapidly.

CAUTION! Consult the literature for additional details before you make your
own sodium ethoxide...this is an exothermic reaction and should only be
performed in a fume hood! And the sodium ethoxide is nasty stuff indeed.
Treat it with respect.

Good Luck!


poate merge un spray , dar poate iti curata nu numai pasta ci si placa de baza :D:gathering:
