Hi,

Can anyone tell me which official standards apply to the 3 following areas?:

1/ Acceptable cleanliness level of bare pcbs direct from the manufacturer.

2/ Acceptable cleanliness level of finished PCB assemblies.

(I am looking for data concerning the maximum ugNaCl / sq.cm allowed.)

3/ Conformal coating of PCB Assemblies.

Thanks
Ben Hammond
