Try mo muna low setting, then increase gradually to the point na tama lang madetach yung paa ng component sa board. Do it sa junk or patapon ng board, practice to get the feel of it. Then pagnakuhha mo na tamang setting, i-matk mo yung temp knob kung saan nakatapat para next time alam mo na optimum setting.

Uy ngayon ko lang nabasa ito ah.
Gawin mong starting temperature yung melting point ng solder which is around 180C ata for leaded and 220C for lead free solder. Tapos timpla timplahin mo yung air and slowly increase the temp. Pagpraktisan mo muna yung solder lead para makuha mo yung melting temperature at airflow.
Paggagamitin mo na sa board, huwag mo diretso sa legs ng iC itutok kaagad. Pasadahan mo yung buong area surrounding the ic ng hotair, pero huwag mo itutok yung nozzle, using circular motion around the IC. Kailangan kasi ipre-heat mo muna yung surrounding pcb area sa chip kundi mag kakaruon ng pop-corn effect at matutuklap yung pcb pag tinamaan na nung na hangin.
