Closed-Loop Systems Allow Chinese Plants to Operate During Lockdown
SHANGHAI—China’s biggest microchip producer, Semiconductor Manufacturing International Corp. (SMIC), and Apple Inc. supplier
Pegatron Corp. continue to operate factories here during the city’s most-recent COVID-19 lockdown by isolating workers and running a closed-off
procedure allowed by local authorities.
These manufacturers are running closed-loop systems where employees are able to keep working as long as they’re confined to the
factory campus and adhere to certain COVID and testing protocols, the people said, asking not to be named discussing internal
procedures. Production capacity, however, may still be affected to some degree due to disruptions to logistics and supply chains.
