Today, let's take a look at the second-generation Apple Pencil, it is said that Apple Pencil dismantling is quite difficult, let us challenge it. APPLE PENCIL (second generation), which uses the lightning mode of the lightning interface, which is changed to the method of side magnetic absorption, so that Apple PenCIL is further improved in applicability. Let's first look at the packaging, as always, very simple.
Open the box, this is a bad pen and has passed the warranty period, so the disassembly and see it will become its best destination.
Apple's things, industrial design has not been said, it looks very exquisite, and the second generation PenCIL integral pen body uses a matte grinding hand.
I looked at it, I only twisted it directly, there is no screw, which may be fixed.
The head is very strange, it may be antenna, maybe the sensor is in this position, can't open.
Then talk nonsense, unpack, there is a battery, not clear in that position, so you can only be removed from two heads.
The hardness is very high, the pliers, and Apple have never been repaired, so there may not be considered maintenance.
It's very laborious to get a little bit, there is a metal.
Then, from this beginning, violent dismantling, and finally we should have no way to restore.
It has been cut with the pliers, it is really difficult, all the gelatin is fixed, and this work has to be boast.
Look close, there is a block of magnets on both sides, used to secure it on the side of the iPad, and the coil is used for wireless charging.
Continue to open, the whole metal is covered, it seems that only the violent dismantling is continued, you have strong you strong, pliers with your bar.
Take the first module, the nib, the speculation should be the pressure sensor module.
The next is the motherboard, the integration is very high, the board looks at the pleasant.
Take it down, close, this PCB level is not apple, and it is not good to be a few layers.
Main chip:
Maxim-MAX14654EWC-circuit protection chip
FAIRCHILD SEMICONDUCTOR-FPF1204 - Circuit Protection Chip
Broadcom-bcm59358aoiupg-touch controller
ADI (AnalogDevices) -343S00 250-Touch Controller

STMICROELECTRONICS-STM32L 052X6-Microcontroller
STMicroelectronics-STM32L 476JGY6-Microcontroller
Be
Nordic (NordicSemiconductor) -NRF52832-RF simulation device
T1-TPS743-power chip
The motherboard and the front pressure sensing module are connected with a cable.
Going back, it is a battery, 53mA battery, and those used by friends know that the battery life is OK.
The head is really antenna.
Here are the dismantling of the whole family, it is really zero broken, the dismantling is really too high.
Circuit city dismantling summary:
In order to maintain a "pen", the motherboard of Apple Pencil is obviously designed. The width of the motherboard is almost the same as the width of the largest component of the area. In addition, there is a plurality of controller chips on the motherboard, so that the components on the motherboard are quite compact. Process design and manufacturing crafts can really be described in excellent, by dismantling us, in order to make Apple Pencil have better protection, Apple does not hesitate to add multi-layer metal pieces and use the in-integrated design.
