Dear Technetters,

I am seeking your advice regarding Electrical Test requirement for a Class 3
PCB.

Would it be acceptable to use a Flying probe tester or not?

For me, Flying Probe Testers do NOT perform a full proof ET as it does not
test each equipotential against all the other equipotentials.. but only the
adjacent ones.. 
Moreover, after the 1-2 first PCBs are tested, then most if not all Flying
Probe Tester are using a "signature" system (discharge/RF/..) to compare a
supposed good first boards with the other "signatures"... made with one
finger probe onto 1 equipotential.. and done!

More and more PCB manufacturers do not even have a bed of nail tester
anymore.. 

And even if they do have it, they tend not to use Flying Probe Tester for
small / medium batch regardless of the Class! 

Thank you for your help/advice  

Meilleures salutations
Very Best Regards
