(f) Wire Bond
To connect the gold wire from the bond pad of the die to the lead finger on the substrate

(g) Plasma Cleaning Repeated
To clean the bonding part with plasma

(h) Mold
To liquified mold compound fills the cavities around the die

(i) Post Cure
To molded material sent for further curing in an oven

(g) Solder Ball
The balls are soldered on the back of the substrate on the specific location

(h) Reflow Cure
Heat the soldered ball for better cAontact with substrawte

(i) Laser Marking
