Hi, We have in out design some 0.13micron devices. We use Fluke 73-III DMM and EZ DM333 DMM for impedance and voltage measurement on the power section of the PCB. Some of the devices had gone bad. There is some argument that the multimeter voltage whose output is 0.74V may be the cause of the problem. Can I know if there is any specific way a CMOS circuit of high pkg density be measured. Also can any one suggest if this is the real reason behind the failures we are encountering. We had taken precautions for ESD related issues. Is there any thing more we are missing on. The VDD section of the chip which was measuring around 10 to 15Kohms has drastically reduced to 3 to 6 ohms. One possibility what we are looking at is the component degradation (Especially decaps).
