Disassembly report: Apple 1-meter Thunderbolt 4 Pro cable A2804.

The following is the disassembly report of Apple’s 1-meter Thunderbolt 4 Pro cable A2804. This data line is made of high-quality materials and is exquisitely designed, ensuring seamless integration with Mac and other devices for efficient charging and data transfer.

Firstly, the outer packaging of this data line is simple but not plain. On the packaging box, we can see the product name and model, as well as some descriptive information. Opening the packaging box, there is a paper manual and a delicate plastic protective case inside. The data line itself is stored inside the protective case, along with a Velcro strap for easy storage.

Next is the disassembly process. We first need to use a knife to cut the Velcro strap and then take the data line out of the plastic protective case. The outer casing of this data line adopts Apple’s unique Lightning docking connector design, which features anti-slip and durable properties. The connection part between the connector and the cable uses strong metal material, further enhancing the durability of the data line.

To further verify the quality of this data line, we can use some testing equipment for testing. For example, we can use a multimeter to test the resistance value of the data line. If the resistance value is within the normal range, it indicates that this data line is very good. At the same time, we can also test the charging and data transfer speed to see if it meets the standards of Thunderbolt 4 Pro.

Overall, Apple 1-meter Thunderbolt 4 Pro Cable A2804 is an excellent product. It has exquisite design, high-quality materials, and excellent performance. If you are looking for a high-quality Thunderbolt 4 Pro data line, this product is definitely worth considering.

The Apple 1-meter Thunderbolt 4 Pro data cable A2804 continues the design of Apple’s 1.8-meter and 3-meter Thunderbolt 4 Pro data cables, featuring a black body with a thick, braided outer jacket. The cable head is made of metal and features a semi-circular curved design on both sides, providing a good feel. The outer shell is engraved with the classic lightning logo, and the USB-C male head has a metal shell with product model A2804, origin (China), and serial number on one side. The USB-C male head is fully PIN-enabled and the pins are gold-plated.

The brass sleeve of the terminal is connected to the sleeve and the USB-C terminal and the wire tail bundle sleeve through laser welding, and the internal wires are welded to the terminal board. The front sides of the terminal board are welded with coaxial wires, and the middle is welded with an E-Marker chip and four parallel positive power line cores.

The E-Marker chip from Infineon is model CYPD2103A, which内置a 48MHz Cortex-M0 CPU, 32KB flash memory, and 4KB SRAM. It supports repeated programming and features internal timers and counters along with support for I2C, SPI, and UART serial interfaces. It also includes an oscillator that eliminates the need for an external crystal.

The Infineon EZ-PD CCG2 internally integrates a Type-C baseband physical layer and includes UFP and EMCA termination resistors. It supports a 2.7-5.5V operating voltage and features CC and VCONN pins that support the IEC61000-4-2 4C level standard of ±8kV contact discharge and 15kV air discharge. It also supports an industrial temperature range of -40 to 85℃.

The data cable features a coaxial wire design, with the wire cores wrapped in shielding mesh and aluminum foil to enhance anti-interference capability. The inner part of the wire cores is filled with tensile wire, which enhances the overall strength of the cable. The use of braided outer jacket further improves the service life of the data cable, with overall fine workmanship and solid materials.
