A Design Defect Is Breaking a Ton of iPhone 6 Pluses - YouTube


On iPhone repair specialty shop "iPad Rehab" based in New York, a large amount of request for repair of certain troubles concerning touch screen regarding iPhone 6/6 Plus has been received.


That is, something like "gray strip" is displayed at the top of the screen and the touch screen will not function.


Jessa Jones of iPad Rehab says, "About three months since iPhone 6 Plus came out, we began to tell you about the problem" A band appears at the top of the screen ".


This is the symptom of "Touch Disease". A gray strip is displayed at the top of the screen. This band seems to be sometimes disappearing once the width of the belt changes by pushing lightly as bending the iPhone.


However, the iPhone who developed Touch Disease will not accept touch operations after a while.


"A lot of people who thought it was a touch screen malfunction brought in a terminal to a special repair shop such as iPad Rehab and fixed it, but the symptoms of Touch Disease will soon recur again."


Jones explaining the cause of Touch Disease points out that the Touch IC chip of the logic board of the iPhone 6/6 Plus has a cause.


According to the decomposition report of iFixit, the Touch IC chip of the logic board of the iPhone 6/6 Plus is a red frame chip. The chip is bonded to several contacts with spherical solder.


Mr. Jones points out that the layout method of the chip differs from the conventional one on the logic board of iPhone 6/6 Plus. This is the logic board of iPhone 5s. A reinforcing agent called underfill is used at the edge of the chip to firmly bond the chip so that it does not come off the board.


On the other hand, underfill is not used on the logic board of iPhone 6/6 Plus.


Only a thin black sticker sticker is affixed so as to cover the chip.


When removing the cover, we were able to check the condenser and chip.


Even the inexpensive model iPhone 5c chip ......


Underfill is used to connect chip and logic board.


For the Touch Disease in iPad Rehab, it is caused by two points: "There is no underfill around the chip" and "The logic board of the iPhone 6 Plus is easy to bend".


The enormous iPhone 6 Plus is remembered for the fact that the "Bend Gate" incident that it was bent easily because of its thinness was also remembered.


If you put it in the back pocket, the iPhone 6 Plus will be twisted in the form of an ass.


Even though this is an extreme example, it is thought that due to a flexible housing, the logic board bends and the chip floats up, which is causing Touch Disease.


To repair the Touch Disease, you only have to reseat the floating Touch IC chip.


Fill a powerful liquid adhesive ... ...


Mr. Jones carefully rearranging the Touch IC chip. Professional skills are indispensable for such tip replacement work, Apple StoreGenius BarBut it is not so, but it is impossible to deal with.


According to Mr. Jones, Apple's official view is "I do not recognize Touch Disease". Therefore, users who have passed the warranty period can recommend "rebuilding the iPhone". Since Apple is not going to approve Touch IC chip replacement work by a repair shop, the way left to the user seems to be to replace or replace the logic board for a fee.


However, Mr. Jones and many other repair shops think that Touch Disease is a design problem and Apple should respond to users who have problems. Touch Disease occurs when the state of the chip deteriorates while using the iPhone 6/6 Plus, so it is unknown when it will occur. And once it occurs, there is no chance of recovery. IFixit says that if symptoms of Touch Disease appear and it is within the warranty period, prompt replacement should be requested.
