00:00

Tear down time. This is the Apple Air

00:02

Tag 2. Let's uh take it out of the box,

00:04

disassemble it to the silicon level, and

00:06

see what it's made out of. So, the Air

00:08

Tag looks very similar to its previous

00:10

generation. Three major changes, I

00:12

understand. A louder speaker, a change

00:15

to the ultra wideband uh chip for better

00:18

performance, and a Bluetooth low energy

00:20

chip, I think, has been updated as well.

00:23

All right, let's start the tear down. Uh

00:25

the silver bit in the middle here is a

00:27

permanent magnet and then it's

00:28

surrounded by this uh wire copper. Uh

00:32

that's the voice coil for the speaker.

00:35

On the outer link, I believe this is the

00:37

ultra wide band antenna coming around

00:40

here. Uh what else can we see? We can

00:43

see what looks like a couple of test

00:44

points. Uh this is probably something

00:46

you can probe here. And then this collar

00:49

proides some sort of mechanical

00:50

fixturing probably for the

00:52

manufacturing.

00:54

That's about all we can see here. Uh

00:55

let's pry off this bit of plastic. It's

00:58

been glued on with a transfer adhesive

01:01

tape. Okay. Uh two big semiconductors uh

01:05

of great importance. Uh this one here is

01:07

the Nordic semiconductor 52 uh 840. Uh

01:12

this is a Bluetooth chip plus an

01:14

associated Cortex M4 processor. Uh this

01:17

is the brains of the operation uh that

01:19

provides the Bluetooth communication uh

01:22

plus all the software on this side here.

01:24

This is the ultra wideband chip. I think

01:26

it's the ultra wideband 2. It's not just

01:28

a chip. It's actually a full assembly.

01:30

There's substrate there and a lot of uh

01:32

circuitry below it. Um this one here

01:35

provides the precise pre uh positioning

01:39

and then the Bluetooth provides uh the

01:41

sort of sensing at a distance. With the

01:44

ultra wideband, you can actually get it.

01:46

So, you can just sort of point your

01:47

phone and uh it will tell you where it

01:50

is quite close. What else can we see? Uh

01:53

there's going to be a power spice

01:54
