苹果公司对iPhone 4 “天线门”事件不做表态?

前期报告 时,苹果公司可能已经悄悄地修改了 iPhone 4,在手机金属边框添加了一个非导电涂层。这将修复由于手触摸到左下角边框造成电桥导致手机信号突然下降的问题。

由于我们从论坛成员得到一个类似最新版手机的独立报告,我们决定进行调查。通过交换了我们其中一部设备(已经有和蓝牙连接无关的问题),了解到苹果已经改变最初的生产制造工艺。

本机的序列号可以确认制造日期,我们原来的电话是在 6 月中旬(25 周)制造。我们得到的新设备是在 7 月初(27 周),足够作出制造工艺变更。

序列号还确定生产工厂(我们没有物件制造工厂的数字编号,但我们可以告诉你两个电话是否来自同一个工厂)。苹果公司一直这样做,而且我们在 Mac 上已经有过有趣的比较,看看他们是否在同一个工厂生产。一个有趣的题外话:我曾经有一个 Mac 来自 Apple’s Elk Grove, California 工厂。如果苹果公司产品在一定时间内是循环出厂,此信息可能有用。

iPhone 4 序列号很容易解码!它这一固定格式:

aabccdddeef
aa = 工厂和机器 ID
b = 年
cc = 生产周
ddd = 唯一标识码
ee = 颜色
f = 大小

我们的产品序列号:
85025xxxA4S(16GB 对比设备)
86025xxxA4T(32GB 测试设备)
86027xxxA4T(32GB 更换设备)

有这么多的苹果 iPhone 手机在外面,很难了解是什么感受。他们可能在其中一家工厂已经转换到新生产程序,或者他们减慢了生产流程,或者这可能是一个互联网神话。唯一的办法是测试一个刚刚从工厂发货的产品。

我们需要你的帮助!如果你在最近几天得到一台 iPhone,检查序列号。如果生产周大于 27,请尝试用万用表测试金属框架阻抗。如果你测试长度大约一英寸部分,电阻应小于 1 欧姆。如果阻值相当高的,你可能拿到的是金属边框做了新涂层的手机(虽然万用表的精度不尽相同,但我们期望一个具有很高的阻抗的非导电涂层)。

苹果公司对 iPhone 4

如何衡量 iPhone 4 的金属边的阻抗。我们的电话边框阻抗 0.6 欧姆,或根本没有阻抗。

You really make it seem so easy with your presentation but I find this topic to be really something which I think I would never understand. It seems too complicated and very broad for me. I am looking forward for your next post.
