On the iPhone X, the main board is using special PCB technology from AT&S to reduce about 53 % of the main board footprint. AT&S has Physical Analysis managed to use two side mounted PCB and a via frame to compact the main board. The APE is located inside the structure under the DRAM package using PoP technology. This new version comes along with a new land-side decoupling capacitors (LSC) Physical Comparison technology. Manufacturing Process Flow Cost Analysis • The Apple A11 is a wafer-level package using new generation of TSMC’s packaging technology with copper pillar as Through inFO Via (TiV) to replace the well-known Through Molded Via (TMV) technology. Compared to standard PoP technology, Apple still have Feedbacks a head start with the inFO packaging and its innovations: Copper Pillars, Redistribution layer, silicon high density capacitor integration, … About System Plus • In this report, the complete packaging is analyzed from the DRAM memory to the LSC developed by TSMC. The report includes a complete cost analysis and price estimation of the device based on a detailed description of the packaging. It also features a complete technology comparison with standard PoP and Shinko’s MCeP PoP packaging used in the market. ©2017 by System Plus Consulting | Apple A11 with TSMC inFO Packaging 3 Apple

  • Final Project Milestone APA Format
    Running head: FINAL PROJECT MILESTONE ONE 1 FINAL PROJECT MILESTONE ONE [Author] [Institution] FINAL PROJECT MILESTONE ONE 2 Essay Technology is basically an application of scientific knowledge which is utilized for practical purposes, more likely in industry. Moreover, it can be referred to as the use of tools, machines, techniques, material and power sources for making the work in an easier and productive manner. Generally, science is concerned with the understanding on how and why things happen, whereas, technology deals with making things happen. The world in today’s life is surrounded with technologies. In every aspect of human lives, technology is making their work easier and in a productive way (Abroms & Phillips, 2011). Although, there are various disadvantages of these technologies but the advantages are always more. Whenever, someone hears the word technology, the first company which comes into their mind is Apple Inc. This is a firm which has brought enormous change in the world by introducing their iPhones and other i products. The company has changed the entire thought process of the humans. Apple Inc. is an American multinational technological corporation which is headquartered in Cupertino, California. The firm designs, develops and sells the consumer electronics products, computer software products and many other online services. Moreover, the hardware product of the firm includes iPhone smartphone, iPad Tablet computer, Mac personal computer, iPod portable media player, Apple smart watch, Apple TV and HomePod smart speaker. Software products include the macOS and iOS operating system, iTunes media player and many more.

The good news is that it'll cost you a lot less to get a lot more! If you've been thinking about upgrading (or downgrading) your iCloud storage plan, you're in luck. Apple has just made some changes to its iCloud storage plan that will probably make you happy. Apple has dropped the 1TB storage tier from the iCloud lineup. But have no fear 1TB subscribers! Apple also dropped the price of 2TB of storage by half the price. All former 1TB subscribers will be automatically upgraded to the 2TB plan without any extra cost. All 2TB subscribers will now only pay $9.99 per month for all the storage you can handle! The new tier structure is as follows: 5GB - Free 50GB - $0.99 200GB - $2.99 2TB - $9.99 If you're still not sure which plan is right for you, we've got a useful little guide to help you out.
