iPhone 7 Said to Expand Use of Single-Chip Electromagnetic Shielding

[Jax44]

So what is the proper term if you think you're so smart?

15. a day? 15.00 a day?

C'mon, I'd love to hear your answer.

Nowhere does it say Apple pays them.

A little more than 15 cents a day

That's from 2013

This is impossible because we all know Apple doesn't innovate.

We? Do you have a small mouse in your pocket?

They're sputtering metal on top of chips. They can electrically shield the chip without having to package the device with a metal lid or shield.

Correct. And "they" refers to...

"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."

These two chip packaging companies are known providers of chip shielding via sputtering. Anybody can hire them to do this service.

So can we now state this is the first move intend to reduce SAR exposure to the head and body regarding to upcoming scientific consensus and (as result) Governmental precautionary measures that reduce radiation exposure?

Nope. See posts 43 and 45 above. And it's not "radiation exposure". It's exposure to electromagnetic fields that radiate outward from an antenna. Like how waves radiate from a pebble dropped in a pond.

The moment you read a website calling it simply "radiation", then you know the site was written by either technical idiots or by someone who is deliberately abusing the word just to frighten you.

This is not to say that electromagnetic effects might not cause health problems, but that it's not anywhere near the same as talking about deadly ionizing radiation such as from a nuclear source.

Why do some MR members feel the need to respond with these passive-aggressive and totally nonconstructive responses?

I did read the article. I read it, I thought about it critically (something obviously a few others here did not do), I compared it with my experience, and realized the article doesn't actually say anything substantive.

The article says only the following on the topic:


Setting aside the poor grammar (maybe a machine translation from Chinese?), this paragraph also doesn't describe how Apple will do it. It makes a generic description about one type of EMI shielding, and asserting that it will be better in various ways without actually giving a single reason. Otherwise it's a pretty empty paragraph. Answer this question: after reading this article, do you know more facts than you did prior to reading it? The answer is mostly no. I'll admit I did not know Apple used this sputtering method on the S1 SoC - so I guess that was new to me...

The substance is YOU were aggressive (like you what the hell you were talking about) in your dismissal.
Do you think I can't read?

If you wondered if Apple was indeed doing something knew, you'd actually write that instead of affirming they did not vehemently. If you don't get what's said (for whatever reason), you don't comment as though you do.

"...densely packed circuit boards allowing for smaller devices or larger batteries."

Yay to bold.

Thinner devices

Don't get too excited. It's Apple. So the likely choice for Ive would be smaller device - IE - thinner.

Definitely won't be for larger batteries

Funnily enough the only time a new iPhone has had a smaller battery than a predecessor coincides with when they got thicker with the 3G and in the last generation:

iPhone - 1,400 mAh
iPhone 3G - 1,150 mAh
iPhone 3GS - 1,219 mAh
iPhone 4 - 1,420 mAh
iPhone 4S - 1,432 mAh
iPhone 5 - 1,440 mAh
iPhone 5C - 1,507 mAh
iPhone 5S - 1,570 mAh
iPhone 6 - 1,810 mAh
iPhone 6 Plus - 2,915 mAh
iPhone 6s - 1,715 mAh
iPhone 6s Plus - 2,750 mAh

It got smaller from 6 to 6s and from 6 + to 6s +. They're trending in the wrong direction.

I mentioned that it did in my post. The iPhone 3G was thicker than the OG iPhone, rumour was the increased size of the 3G radio required the space hence the dip. With the 6s and 6s Plus the devices again are thicker than predecessors, but the battery size took a hit due to 3D Touch.

7 straight increases followed by a dip is probably not trend territory just yet.

If you bothered to read the article, you'd find out what they're doing.

They're sputtering metal on top of chips. They can electrically shield the chip without having to package the device with a metal lid or shield.

Yup. In this case, lack of mounting holes, shield footprints, etc. buys you board space back and eliminates big holes in your planes. The improvement to voltage drops probably doesn't matter for low current density mobile platforms. Thermal probably comes out near a wash when increased component density cancels out slightly improved thermal paths.

 

[Tech198]

increase density + more chips = faster performance.. ....

Ideally, we could probably even see the iPhone case be used as EMI shielding,,, would that even work??.. Don't see why not see we already use it for antenna bands.

(heh, look at all those people dressed in bunny type suits.. Its like walking into full on medical centre)

 

[ray6712]

probably upping the shielding because they intend to make the A10 a SIP design similiar to the Apple Watch. Place as many components as possible in the smallest place as possible. make the phone physically smaller while increasing battery at the same time. Apple Watch and the new Macbook are good examples of this thinking, and also another reason to remove the headphone jack. Removing the larger DAC for a smaller one or moving the DAC to the speakers themselves. could be radically wrong on the DAC thing though just a hypothesis

This post is enough for me to smile for the rest of the day. Take care, American Hero.
