A method of manufacture of an integrated circuit packaging system includes: providing a package substrate; mounting an integrated circuit die on the package substrate; and attaching a heat spreader assembly, having a thermal adhesive layer formed therein, to the package substrate and the integrated circuit die. In one embodiment, the mobile device is configured to receive a product code associated with a manufacturer product offered for sale at a merchant location. At least one of the broad surface portions of the pouch includes a closable opening for admitting a waste holding bag, and that reduces the risk of spillage of the contents of the waste holding bag as it is removed from the pouch. The set of error intersections is updated, based at least in part on the Chase decoding, to obtain an updated set of error intersections. The controller then adjusts the duty cycle of the PWM signal to correspond to the value.
