I'm trying to create a formula sheet to measure defects in percentages quantities..
example: 30 DU (defected uints) are to be inspected, all faults per unit are to be recorded... % off faults against total number of units.
I will also need to record total percentage of each error against all boards..
Total number of units will change depending on batch size, up to a maximum of 200 units...
I have attached a spread sheet with the information I need to record..
Hopefully it will make sense ?!?
If you can think of an easier way to collate info, all input will be greatly appreciated.
Thanks in advance
