Electromagnetic interference (EMI) shielding has recently been rumored to be shielding the iPhone 7. It will individually shield most of the device's major chips. This is great news because it will help to maintain the iPhone's performance while stopping potential interference signals which constantly become a bigger possibility with each new phone released.
Apple has used EMI shielding on large portions of the iPhone's circuit board in the past. The iPhone 7 will apparently include a broader array of single-chip EMI shields, from radio frequency to wireless LAN and Bluetooth chips. The amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic field. The cost of that production is also predicted to increase with the improved technology. South Korean manufacturers StatsChipPac and Amkor are both said to be responsible for the production of the EMI shielding process on the iPhone 7 line.
“As clock signals of digital chips have increased and as diverse functions such as 3D-touch and others have recently added, reduction of electromagnetic waves have emerged as major topic of this industry.” said a representative of this industry. “As other Smartphone businesses might be looking to apply EMI Shield technology to major chips just as Apple did, packaging and other related equipment industries will benefit a lot from this.”
Similar EMI shielding was applied to the S1 chip package used in the Apple Watch last year, so expect this rumor to come true. As always, feel free to comment or contact us. Thanks!
