IC packagers Advanced Semiconductor Engineering (ASE) and Siliconware Precision Industries (SPIL) have said their supply chains will not be affected by two major earthquakes that struck Kumamoto Prefecture in Japan on April 14 and 16.

ASE indicated operations at its manufacturing site in Takahata, Yamagata, which was acquired from NEC in 2004, were not affected by the recent powerful earthquakes.

ASE's production base in Yamagata offers BGA packaging and other backend services for analog, digital and mixed-signal ICs. Monthly sales generated from the site are estimated at around US$100 million.

SPIL noted one of its suppliers which provides QFN substrate materials halted production due to the quakes. But with SPIL's dual-source strategy, there is no impact on SPIL's operations, the company said.

ASE's share price closed at NT$35.25 (NT$1.09) on the Taiwan Stock Exchange (TSE) on April 19, up NT$0.95, while SPIL's fell NT$0.65 to close at NT$49.85.
