JCET will be a new contract provider of SiP assembly services for Apple, adding to the existing suppliers including Japan's Murata and Universal Scientific Industrial (USI) of Taiwan-based Advanced Semiconductor Engineering (ASE), according to industry sources. STATS ChipPAC, which was acquired by JCET earlier in 2015, already has its Korea-based operation obtain certification from Apple, said the sources.
Notably, JCET's board has approved a plan to spend $200 million to expand production lines for SiP modules. Currently, Apple uses a SiP design for the Apple Watch and there have been rumors that the company is looking to do the same for the iPhone.
