Affected by two earthquakes in Southern Japan last week, electronics giant Sony suspended work at its Kumamoto factory that produces CIS (CMOS Image Sensors) which are key components of Apple iPhones, reported Reuters on April 16. Sony takes up around 40% of the worldwide CIS market and the suspension of production at its Kumamoto factory might have an impact on the availability of iPhone 6S,SE and the upcoming 7, said the report. However, Sony stated it is not expecting any immediate supply disruption while still having some inventories. Besides, its image sensor plants in Nagasaki and Oita, also on the southern Japanese island of Kyushu, have fully resumed operation, said the company.
