DV-series notebook? :) --- Enviado do meu Motorola PT550 Meu site: http://www.tabalabs.com.br ----- Original Message ----- From: "Scott Quinn" <saquinn624 at aol.com> To: <cctalk at classiccmp.org> Sent: Thursday, November 22, 2012 7:45 PM Subject: BGA resoldering - flux? I have a non-CC HP device that has developed issues, probably because of a combination of the lead-free transition and usual Chinese quality. I'm planning on attempting a re-solder by reflowing in an oven (no hot-air rework station yet). It seems as though it would be best to find some way to flux the balls to ensure that the connection is good. I'm not removing the chip, so would a solution of rosin flux diluted in alcohol and dripped onto the BGA work? Any better way, or is it unnecessary? My plan was to ramp it up to 400F in an oven, soak for 5 mins, then cool down to minimize thermal issues. Does this sound good?
