Can anyone tell if blanking G-6050 cause corrion on 42 alloy leadframe
surface?
This type of blanking oil has chlorintaed compounds in it shich will cause
corrosion. Is this true?
Is corroded 42 alloy surface susceptible to contamination. I have an Auger
analysis and found traces of Cl Na C and O.

Please e-mail me if you've got the answer.

Thanks & regards
