Once a die has been attached and bonded, it is still fragile. The packaging technician's job is to turn that assembly into a robust, finished component. On a typical OSAT or ATMP line, that means running and monitoring moulding presses that encapsulate the die, post-mould cure ovens, deflash and plating steps, laser marking, trim and form, and singulation. On substrate-based packages the work extends to ball attach, reflow and saw singulation.
The role is hands-on and highly procedural. A packaging technician sets up tools for each product, loads and unloads strips and magazines, checks the first pieces off each run, and keeps the tool within its process window through the shift. They read and follow standard operating procedures, record results in the manufacturing execution system, and raise the alarm the moment something drifts, whether that is incomplete fill, voids, wire sweep, mis-marking, or dimensional issues after trim and form.
Good packaging technicians also protect yield in quieter ways. They handle material to strict ESD and cleanliness rules, manage mould compound and consumables by lot and shelf life, carry out routine cleaning and first-level maintenance, and make clean handovers at shift change. When a problem goes beyond first-level troubleshooting, they give equipment and process engineers the precise information they need to fix it quickly.
Because the packaging steps sit between assembly and test, a weak packaging team shows up immediately as scrap, rework and delayed shipments. A strong one is one of the biggest levers a new Indian plant has on output and quality in its first year.
