Slideshow: Apple iPad 4 Teardown
11/13/2012

< Previous   Image 2 of 21      Next >

When we picked up our iPad 4 on Nov. 2 (coincidentally, at the same time we picked up our iPad mini), we took it to our lab as soon as we could to take it apart and analyze what differences there were, if any, between this new iPad and the iPad 3. We used a heat gun to soften the adhesive around the touchscreen.

Tool_maker, you're right about the glue being the problem with repairing the tear-down. Once the glue is broken, that's it for reconstruction.

  I did not mean to imply that I had the expertise to undertake this particular teardown, I was just talking in general terms. I have taken somethings apart and been able to repair simple items. Eight track tapes, minnow bucket areators and a flash attachment for my 35mm camera. They were already "Throw-away" if I could not fix them. I would never attempt the teardown in this video, but might be willing to take the cover off and look at stuff if it was screwed on rather than glued.

That makes sense, Tool_maker. I didn't realize you had experience in this area. So basically, you have to ruin the product in order to do the tear down.

  I have never been able to clean all residue off the surfaces to get the proper seal. Also since it is an electronic device is it not the case that things could become overheated and then malfuction. If there are mechanical fasteners, even rivets, I am much more likely to attempt tear down and repair. But, welds, glue, crimp and seal have rarely worked well for me when I attempt to open and reseal.

Tool-maker -- why is hot glue a probably for reassembly?

  I suspect it ends up in somebody's lab facility so some engineer can figure out what parts can be altered slightly, copied and stolen for a competitors product. That is what passes for research in many instances today.

  As soon as I see Hot Glue being an integral part of the assembly, I decide against reassembly.

I'm still amazed, Chuck, by the small size of computer brains. The smart phones really prove it. The power of NASA moon-shot brains are now in the palm of our hand.

Never thought of a tear down as art. Personally, I would try to put the device back together and use it. But I will say the brains of this device is a thing of beauty.

I've always wondered what it is about that iPxxx dock connector that makes it so much better than USB2.0 micro connector that seems to work for everybody else.

I think it's obvious - Apple wants/needs to spread the Lightning connector across their product line as quickly as possible, otherwise it remains something of a "quirk" on the iPhone 5 and iPad mini vs the enormous installed base of the larger dock connector. 


Personally at this time I'd still go for the iPad4 as the CPU change is IMO not worth dealing with the connector incompatibility (also have an iPhone 4 and a 4S).

With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
The Industrial Internet of Things is bringing a previously reluctant process industry into the wireless fold. The ability to connect smart sensors to the Internet has spiked the demand for wireless devices in process manufacturing, according to the new study from ARC Advisory Group.
Enterprising Tesla Model S owner Steve Sasman seems to have figured out a way of recouping some of the cost on his car by renting the trunk out on AirBnB, the room/house rental website.
Everyone has had the experience of trying to scrape the last of the peanut butter or mayonnaise from the bottom of a glass jar without getting your hand sticky. Inventor Ron Jidmar thinks he has a solution to all of that nonsense with a flexible jar design that can be squeezed with one hand to lift contents from the bottom to the top of a jar or container, leaving the other hand free to scoop the contents out cleanly.
