目前很多MP4、数码相框都开始采用BGA封装芯片,如图1、图2所示。凌阳SPAC536方案的MP4采用的就是BGA封装。而在笔记本电脑中BGA封装芯片运用得更多,这里就BGA封装的概念给出解释。20世纪90年代,随着技术的进步,芯片集成度不断提高,I/O(输入/输出)引脚数急剧增加,功耗也随之增大,对集成电路封装的要求也更加严格。为了满足
Currently a lot of MP4, digital photo frame are beginning to use BGA package chip, shown in Figure 1, Figure 2. Sunplus SPAC536 program uses MP4 is BGA package. The BGA package in the notebook computer chip used more, here on the concept of BGA package gives an explanation. In the 1990s, with the advancement of technology, the chip integration increased continuously, the number of pins of I / O (I / O) increased sharply, the power consumption also increased, and the requirements of integrated circuit package were also more strict. to satisfy
