Apply plenty of flux, then use hot air at roughly 350°C (660°F) to evenly heat all four sides until the solder melts. Lift gently with tweezers.
: Includes PWM (Pulse Width Modulation) for fan speed control, A/D and D/A converters, and multiple GPIO pins. kb926qf datasheet
The KB926QF acts as an Embedded Controller (EC) . In a computer system, it handles the "always-on" tasks, such as listening for the power button press, controlling fan speeds, monitoring temperatures, and handling keyboard input, even when the main CPU is off or in sleep mode. Apply plenty of flux, then use hot air
The KB926QF is most commonly found on motherboards from manufacturers such as Compal, Quanta, Wistron, and Foxconn, used in brands like Acer, Dell, HP, and Toshiba. Common Fault Symptoms The KB926QF acts as an Embedded Controller (EC)
The IC unifies several critical sub-systems into a single LQFP (Low-profile Quad Flat Package):
