Kunshan, a city in Jiangsu province situated between Shanghai and Suzhou, began a full city-wide lockdown on April 2 in an attempt to halt the spread of Covid-19. Kunshan has a printed circuit board (PCB) industrial cluster according to ICSmart, a Chinese media outlet focusing on integrated circuits, and the businesses based there have been impacted by the lockdown. Taiwan-headquartered PCB manufacturers Elite Material and Nan Ya were among those to confirm plans to stop production at their Kunshan facilities after the lockdown was announced. Elite Material’s production volume in Kunshan accounts for 30% to 40% of the company’s total, while 40% of Nan Ya’s production ordinarily happens in the city. Kunshan, which is also home to a large number of semiconductor manufacturers, was originally due to lift its lockdown on Wednesday, however, given that the neighboring city of Shanghai has extended its lockdown indefinitely it remains unclear when businesses will be able to restart.
