This is the first stage of HDD assembly wherein the HGAs are mounted on the tips of actuator blocks. Assembled with flexible printed circuits, coil and unit bearing.

Disk stacking is where the required number of disk media is determined and stacked onto a DC motor separated by spacer rings.

Head insertion is the process where the Actuator Assembly bearing the MR Heads is matched with the Spindle Assemble carrying the Disks. The 2 assemblies are combined carefully positioning the head in between disks. The combined assemblies are then mounted on a base with matching cover to complete the Disk Enclosure or DE..

PCBA Mounting is the first process done outside the cleanroom. This is where the Printed Circuit Board Assemble is installed on Disk Enclosures to complete the Hard Disk Drive.

Hard Disk Drive is subjected to a series of function and reliability tests to ensure its superb quality. Function tests are conducted to calibrate the basic functions of the HDD. Moreso, the drives are subjected to a 24-hour Self-Running Test at high temperature. The drives are also subjected to 4-corner tests where varying conditions of high and low temperature and maximum and minimum voltage are simulated.

The HDDs are packed and sealed with the highest standard of quality. The drives are stored in a temperature and humidity controlled environment and handled with utmost care to preserve its quality.
