Hi Simon, Thanks for the immediate reply. We really appreciate it very much. Currently, we are using Class 2 for the visual inspection criteria of our telecom boards. In IPC-A-610 Rev. C criteria, there are TARGET, ACCEPTABLE and REJECT criterias.

Allowable bow & twist: Together, both IPC-A-600G and IPC-6012B represent the core IPC documents for describing the acceptable and nonconforming conditions that are either externally or internally visible on finished printed boards. IPC-A-600G relies

MTBF is hard to nail down raw data based on whether or not it is classified as IPC CII or CIII alone. Given that most failures are environmentally based, you might be able to get this data for CII and CIII in similar environmental testing situations

Hi This is an excellent question or research project. I would call the IPC and find out if anyone has already done this work. My guess is that Class III should be slightly better, yet considering the application difference where Class III is used
IPC is the trade association for the printed wiring board and electronics assembly industries.
