Hi everyone,
It has been mentioned that DPMO offers large advantages over First Pass
yield calculations for measuring process performance!!regarding the same I
have a few queries:
1. What are the benchmarks for using DPMO as measures of process
performance?
2. How is DPMO being employed in improving process performance?
3. Besides the IPC 7912 is any other approach being followed for estimating
DPMO levels.
4. What opportunities (Component, Placement, Termination) exist at each
stage of process, as Stencil printing, Placement and post reflow??
5. How is OMI interpreted as a measure of process performance??
6. What are the benchmark values used for the same?
Thanks and have a great weekend.
Praveen
