Technetters,
After routing stage the PCBs are washed to remove dust , fingerprints etc .
Normally , this is done using washing machine fitted with hot water rinse ,
soft brushes , high pressure rinse , DI rinse and dryer . As long as the PCB
is bigger than , say , 7" by 4" , we have no problems . Probles are with
really small boards such as 2" by 3" or even less .
What kind of washing machines are used for such small boards ?
