I. appearance

Apple's traditional white packaging, simple style atmosphere, full of force. Thunderbolt 3 (USB-C) in the upper left corner reflects the noble temperament deeply, which is as different as fireflies in the night.

The back of the box is written in six languages, English, French, Spanish and Japanese saying "Thunderbolt 3 (USB-C) 0.8m", then the interface looks like it can connect Apple's laptop Macbook and desktop. The lower right corner is the price tag, right! It's HK knife 288 yuan, a data line worth HK $288! Take a picture with the charge head VIP card and take a look while it's still in good condition.

Attached is the receipt, which I bought at the Apple Store in Kowloon Tong under the code name MQ4H2FE/A. Two pieces totaled HK$576. Even if it's a HK$288 data line, it will be disassembled in the charging head network, so that it can't be disassembled again.

The small label indicates the noble lineage of this thread, code MQ4H2FE/A, designed by Apple in California and made in China. Apple model A1896.

On the other hand, the same information is expressed in Chinese characters.

Compatible with Thunderbolt 3 (USB-C) devices, of course, Apple products, the specifications that support this line are Thunderbolt 3 (USB-C).

Remove the package and fix the two USB-C heads on the cardboard.

Thread winding is also cleverly fixed.

Although it's a data line, Apple also provides detailed instructions.

Like the original Apple data line, the white material does not seem to be very durable. It is also printed with "Designed by Apple in California, Assembled in China" and serial number.

Packing is made of paper jackets with buttons.

White body, 80cm, USB-C at both ends.

Counting the two USB-C heads, the length of the cable is 80CM, or 0.8m.

The diameter of the line is 4.4 mm, which is relatively thick.

Two： test

Using this line to read the PDO information of Apple's 87W power adapter, you can read PDO of 20V and 4.3A.

Using other wires to read the PD information of Apple's 87W power adapter, the maximum current is only 3A, which is limited by E-mark.

Using other lines to read the PD information of Netease 65W power adapter, the maximum current is only 3A, which is limited by E-mark.

Use this line to read the PDO information of Netease 65W power adapter. The maximum PDO can be 20V, 3.25A.

Reading the E-Mark information of this line, you can see that it supports 20V 5A, USB 3.1 Gen2.

Another E-Mark message for USB-C is Microsoft, which supports 20V 3A and USB 3.1 Gen2.

Apple has always practiced plastic casing.

Using this wire and Apple 87W to charge the mobile power supply of 20000PD, the visible voltage is 20V, the current is 3.364A, and the total power is 68W.

Lightning signs at joints, meticulous workmanship.

Contacts are complete, up and down 24 pins are complete.

Attached is a brief description of 24pin of USB-C.

The material of the thread is not smooth. The feel is astringent, just like the thread of Apple's mobile phone, which may be the environmentally friendly decomposition material Apple has been using.

SN begins with subtitle DTN.

Every line is printed with words.

The word "radium carving" can be seen from a micro-distance.

It can be seen that there are many wires combined to form this cable.

Similar structure to other data lines, but more obvious lines.

Attach Wikipedia's instructions on the color of USB-C cables. The latter comparison is much simpler.

Three： dismantling

Dismantle in turn, and then dismantle the wires in the core. The winding shield inside the outer skin is softer than the woven handle.

The net is made of aluminium foil. When the foil is removed, multiple strands of wire can be seen.

Look carefully, four pull-proof, two red, two blue, two gold, two yellow, four thin lines, one strong black.

The cross section shows that there is a shielding layer inside one of the light blue lines.

Inside the golden line there is a shielding layer, in the middle is the core.

The thinnest thread has a winding copper core inside the epidermis.

Green core.

The original black core, there are three strands inside, in addition to anti-pulling core.

There are shields in the two thin ones.

Blue line.

Red line.

Four thinnest cores.

Decompose all.

There are many smaller cables in a single cable, which is quite complicated.

Remove the head and tear the hard shell of the USB-C head violently.

Cut out the sleeve. It's shielded inside.

The whole steel head without riveting process is quite complicated.

The head is a steel sleeve with printing on it.

Two rows of solder joints are dense, and there are also solder joints on the side. The whole circle is full of solder joints, which is rare in wire rods.

There's no place to start. Cut the shield directly.

Inside is transparent glue.

Arrangements are welded on both sides of the pcb.

On the other hand, PCB has chips.

Open the head steel sleeve.

24 needle contact gold plating.

Side view of a very thick stylus, 5A high current protection.

The whole chip CPD21038-713-6227. Estimates are customized and no information is available.

The cut head can still read the emark.

Read emark at both ends, but not at the other end.

The other end is disassembled. The clasp is different from the previous one.

The same way, the same process, there are radium carving words.

On the other side of the radium sculpture.

Also pull out the head steel sleeve.

There is also a chip.

On the other hand, a row of capacitors.

Two heads are put together and each has a chip.

The other side of the head.

Head contacts are the same.

Two USB-C heads are disassembled.
