The Low Yield Rate Of Touch Screen Makes The Cost Of IPad2 High

The components and suppliers of iPad2 are the same with the first generation. There are some changes on the case and battery, but the touch screen always keeps the same. In these aspects, the iPad2 is similar with iPad2. They use the same component from the NAND Flash to the drive. In addition, iPad2 also applies the same core chip with iPhone 4. The other components, including the application processor, Bluetooth, radio frequency, GPRS and the WLAN chip, all choose the same suppliers of iPad1. The only difference is that iPad2 uses the updated editions. However, the cost of the touch screen is too high, which is 127 US dollars. The cost is higher than estimated one.

From the start to end, the manufacturers are always facing a succession of challenges which are the main reasons of high cost. Although many manufacturers devote themselves to improving this situation, the yield rate is still very low. Therefore, the price is higher than expected. Besides, the unceasing improvement of the touch screen drives the price of iPad2 to the higher point. The other elements, including the expensive adhesive, the thinner Gorilla glasses and the additional devices, all make the cost high.

In the iPad2 of GSM/HSPA, Apple still uses the same frequency and power amplifier solution with the iPhone 4. The CDMA iPhone4 has applied the wireless chip which produced by Qualcomm Company; therefore, Apple may draw the chip suppliers in and use the chips of Qualcomm in the iPad2 of GSM/HSPA edition. When compared with A4 processor, the cost of A5 processor is higher by seventy-five percent, because its performance and design are improved. A5 processor, which is also used by the other manufacturers, is designed by Apple Company. Apple has the intellectual property rights of this processor. The over cost of this processor can be ignored after the production of iPad2.

The more advanced battery is used by iPad2. The battery costs 25 US dollars in iPad2, while it costs 21 US dollars in the first generation. The new battery is thinner and uses three units. Apple has never used the standard battery plan, which challenges its suppliers. They should develop the unique solutions to meet its demand. Although the other manufacturers also apply the similar flat battery, this thin battery and unique battery management circuit is especially designed for Apple. Besides, the battery management circuit plays an important role in iPad2, because it is relevant to the service life of this component. The related integrated circuit MC54HC27J.
