Apple supplier and Taiwanese firm Unimicron Technology Corporation said on Thursday that it has partially resumed production at one of its two plants in the locked-down eastern China city of Kunshan.
Unimicron said one plant had resumed some production under a “closed-loop management” system that keeps workers isolated inside, while the other would remain closed to comply with Covid-19 curbs.
A company representative said it was difficult to estimate current production capacity, but it was “not high”.
A chip substrate and printed circuit board maker that supplies Apple and Intel, Unimicron plans to keep one plant running under the closed-loop system until next Wednesday.
Most of Unimicron’s manufacturing capacity is in Taiwan but it also has other plants in China, Germany and Japan.
China has put Shanghai under a tight lockdown since late March and neighbouring Kunshan has also tightened curbs to control the country’s biggest Covid-19 outbreak since the coronavirus was discovered in late 2019 in the city of Wuhan.
That had caused dozens of Taiwanese firms, many making parts for the semiconductor and electronics industries, to suspend operations.
Unimicron’s shares were down 1% on Thursday morning, while the broader index was flat.
