MTK平台手机的生产线测试合格率的问题

cuijw

我这边合格率很低，尤其是211、204的问题特别多，造成合格率低、误测率高、效率低的问题。各位也有这个问题吗？

请问你们的204、211是什么故障坏机？我们是用自己做的程序测试MTK平台，合格率98%左右，误测率3%左右。

<P>羡慕4楼，我们用的是MTK提供的ATE，所以毛病很多、不实用</P><P>各位有什么好办法吗？</P>

出现METAAPP_BOOT_FAIL = 204和METAAPP_CONNECT_WITH_TARGET_FAIL = 211这现象，在保证手机数据线与PC连接良好的情况下，可以在MTK_6218B_SETUP.ini文件里把Enter META Mode Timeout = 10000和Enter META Timer Delay = 2.0延迟时间改为50000和5.0，就可以了。

cuijw

<P>以前试过修改这两个事件,但感觉意义不大</P><P>还有其他办法吗?</P>

<P>自己可以编写阿.</P>[em01]

请教一下校准Pathloss Calibration Fail = 302
和ADC Calibration Fail = 305出错主要是什么原因
Pathloss Calibration Fail = 302
APC Calibration Fail = 303
PHASE ERROR Calibration Fail = 304
ADC Calibration Fail = 305

ADC校准出错的可能原因有：（1）校准模板ADC的参数不对（2）电路上硬件有问题（3）测试用电源仪表有问题或设置问题（4）电源输出的接线方式不对等[br]<p align=right><font color=red>+1 RD币</font></p>

修改上电后DELAY时间,因为这个DELAY跟很多因素有关,如MTK芯片,6217,6218,6219,6226他们进入测试模式的反应时间不同,也与电脑配置有关![br]<p align=right><font color=red>+1 RD币</font></p>
