If you build to this IPC standard, it is mandatory to provide OE. Alongside this, if your technology is ahead of the standards, you can use the OE concept to demonstrate the validity of how you test.
You may be familiar with the number 1.56µg/cm² from the ROSE test. This number has now been removed and is no longer a requirement for quality. OE is the replacement.
Reliability in the everyday world is of paramount importance. The electronics that Impact our daily life get more and more important, so ensuring they work and are reliable is everything.
Regularly! Having used SIR to achieve OE, you now need to prove it repeatably! You can do this quickly and effectively on a shop floor using the Ionic Contamination technique for process control.
