Segregation Procedure
Administrative containment halts the movement of electronic components upon the detection of non-conformance during incoming inspection or assembly stages. A lot quarantine protocol acts as the formal mechanism that triggers this state, preventing suspect parts from entering the production line or reaching inventory. It forces an immediate cessation of all automated pick and place activity involving the identified material until a quality review determines the viability of the batch.
This control barrier ensures that compromised hardware does not contaminate final circuit assemblies.
Review Criteria
Quality personnel initiate this action after verifying that physical defects or parametric variations fall outside defined acceptance limits. The protocol necessitates the physical relocation of the affected goods to a restricted zone, which effectively isolates the inventory from standard warehouse logistics. Labels and digital flags mark the containers to prevent unauthorized withdrawal or usage during the investigation period.
Technicians evaluate the failure rate against specific workmanship standards, such as those governing solderability or dimensional tolerances for surface mount components. Results from these inspections dictate whether the material undergoes rework, return to the vendor, or destruction.
Validation Impact
Accurate enforcement of these isolation rules prevents the propagation of systemic failures through expensive sub-assembly processes. Production throughput benefits from the exclusion of problematic lots that would otherwise create erratic performance in finished printed circuit boards. Establishing a rigorous gate at the point of receipt minimizes the risk of hidden faults surfacing during final electrical testing.
Proper segregation of non-conforming items maintains the integrity of the supply chain by ensuring that only verified material proceeds to integration.
