Hi,

What's the acceptable criteria for Ion Chromatography Testing? I found a test lab but they said we have to define what is pass or failed. Can anyone guide me to the right document either IPC or MIL Std?

thanks,

You can start with J-STD-001 for assemblies or IPC-6012 for Bare Boards.

J-STD-001 8.4.1 Chlorine content should not exceed the following:

<0.75 to 0.78 ug/cm2 for WSF

Why only for Chlorine Content? I know its corrosive.

thanks davef for your never ending assistance.

J-STD-001 8.4.1 Chlorine content should not exceed the following:

<0.75 to 0.78 ug/cm2 for WSF

Why only for Chlorine Content? I know its corrosive. And how come the criteria has a range when it says should not exceed? Or I'm just confused?
