According to noted KGI Securities analyst Ming-Chi Kuo, Apple is planning to embed Touch ID in every non-iPod iOS device launched this year, including both iPhone 6 versions, the second-generation iPad Air and refreshed iPad mini with Retina display. In a research note obtained by AppleInsider, Kuo goes on to say that Apple will switch up chemicals used in Touch ID module production to boost durability, possibly moving to tin as applied with Japan Unix’s laser welding equipment. As for manufacturing, Apple partner Taiwan Semiconductor Manufacturing Co. is said to be the go-to foundry for Touch ID production, with redistribution layer services covered by XinTec and WLCSP and packaging going to ASE. ASE and Sharp will be responsible for the module itself, while welding equipment is to be furnished by Japan Unix through Taiwanese agent Sunnic.
