Typical Failure Rates

Darren,

You may/will get people referring you to the archives, which is a fair shout.

But, by "failure rate" you probably mean "acceptance". What is good and bad depends upon your own acceptance criteria (IPC-610 ?).

Find out what the acceptance criteria is, compare your manufacturing results to that and what ever doesn't meet that criteria is a "failure".

If your criteria are customer driven, ensure that they are achievable and realistic, not just what some purchasing guy thinks............meanwhile in the real world (!?)

Regards,

Chris May
