In this article we will talk about the main elements located on the iPad 2 motherboard. Above is a diagram of the iPad 2 motherboard with the main elements labeled. Let's take a closer look at what they mean.

• J5900, J3700, J3010, J3011 - connectors for connecting cables
• U3100 - Broadcom BCM5973KFBGH Microcontroller used for touchscreen. Microcontroller used for correct operation of the touchscreen
• U3001 - Broadcom BCM5974 CKFBGH capacitative touchscreen controller. Microcontroller responding to changes in touchscreen capacity
• The diagram at the top right shows a Wi-Fi board (WLAN/BT PCB). This is a Broadcom BCM43291HKUBC chip
• U3103 - Texas Instruments CD3240B0 11AZ4JT G1 (controls the sensor), works in tandem with Broadcom BCM5973 and BCM5974.
• U8100 - Apple 343S0542 - power management chip. Inductors and capacitors around are the wiring of the chip
• U2000 - S6T2MLC N33C50V - power management chip
• U0652 - Apple A5 - processor, the heart of the second iPad
• U1410, U1400 - Toshiba TH58NVG7D2FLA89 - NAND FLASH (iPad memory 2. In this case 32GB)
• J5600, J5501 - connectors for cables

Most often, knowledge about the marking of an individual chip is required when filling an iPad. In this case, we carry out BGA soldering of the microcircuits and replace the flooded faulty microcircuit with a working chip. This helps avoid costly motherboard replacements!
