\tI reheated the existing IC using an SMD rework heatgun which I know the temperature of the heatgun.<\/p>\n
\tApply flux generously before re-flowing.<\/p>\n
\t1. Warm up the IC area at ~200C for 2 mins.
\t2. Heat the IC area at ~250C for 2 mins.
\t3. Reflow the IC at ~300C for 30-45 secs.
\t4. Use a pencil (I used a strong toothpick ) to put pressure on the audio IC as you cool down the IC area for at least 5 mins with cool air.<\/p>\n
\tThose are the hot air temp so it will be cooler when it hits the IC\/board (nozzle >15mm above the IC).<\/p>\n
\tPS: I also used this technique to fix the RROD on XBOX 360 and YLOD on PS3 but with longer heating times due to the board thickness and IC size<\/p>\n
\t <\/p>\n
\tOnly had to heat the component side due to the thin board (steps 1-3).<\/p>\n
\tIt is recommended to cool the board quickly to stop crystallization (i think). Just use a hair dryer on cool setting and don’t bump the board<\/p>\n
