Floor Life Tracking

System Registry

Electronic tracking databases or manual log sheets record each transition of a component reel between dry storage and the active assembly floor. These logs capture the component part number, the moisture sensitivity level, the time of removal from the dry cabinet, and the duration of assembly floor exposure. If the accumulated exposure time exceeds the allowed threshold for that device class, the system flags the reel as expired and blocks it from being loaded onto the pick-and-place machine.

This automated lockout protects the assembly from assembly-level soldering failures.

Assembly Risk

Expired components require a low-temperature bake to remove the absorbed moisture safely before they can be processed through the reflow oven. This baking step resets the exposure clock but can degrade the solderability of the component leads if performed repeatedly. Accurate tracking minimizes the need for these corrective bake cycles, preserving both production throughput and joint quality.
