Description: 用担心QFP 那样的引脚变形问题。
该封装是美国Motorola 公司开发的，首先在便携式电话等设备中被采用，今后在美国有可
能在个人计算机中普及。最初，BGA 的引脚(凸点)中心距为1.5mm，引脚数为225。现在也有
一些LSI 厂家正在开发500 引脚的BGA。
BGA 的问题是回流焊后的外观检查。现在尚不清楚是否有效的外观检查方法。有的认为，
由于焊接的中心距较大，连接可以看作是稳定的，只能通过功能检查来处理。
美国Motorola 公司把用模压树脂密封的封装称为OMPAC，而把灌封方法密封的封装称为
GPAC(见OMPAC 和GPAC)。-To worry about that kind of pin QFP deformation. The package is developed by Motorola, the first portable phones and other devices used in the future in the United States is possible in the popularity of personal computers. Initially, BGA pin (bump) for the center distance of 1.5mm, pin number is 225. LSI now some manufacturers are developing 500-pin BGA. BGA problem is the appearance after reflow inspection. It is not clear whether the appearance of an effective method of examination. Some believe that as a result of welding the center distance of a larger connection can be seen as a stable, only through the function test to deal with it. Motorola United States companies to use molded resin sealed package called OMPAC, and the casting method known as the sealed package GPAC (see OMPAC and GPAC).

Description: BGA(ball grid array)
球形触点陈列，表面贴装型封装之一。在印刷基板的背面按陈列方式制作出球形凸点用以 代替引脚，在印刷基板的正面装配LSI 芯片，然后用模压树脂或灌封方法进行密封。也称为凸点陈列载体(PAC)。引脚可超过200，是多引脚LSI 用的一种封装。封装本体也可做得比QFP(四侧引脚扁平封装)小。例如，引脚中心距为1.5mm 的360 引脚BGA 仅为31-BGA (ball grid array) display spherical contact, surface mount type packages. In the back of the printed substrate produced by the display means to replace the pin ball bump in the printing substrate positive LSI chip assembly, and then molded resin or potting sealing methods. Also known as the Braille display vector (PAC). Pin can be more than 200, is a multi-pin LSI with a package. Package body can also better than QFP (four-side-pin flat pack) Small. For example, the center distance for the 1.5mm pin 360-pin BGA only 31
