Hello,
May I get someone' help on PCBA Cleanliness test process?
For Ionic Residues on PCBA, there are three methods of testing in IPC-TM-650: Dynamic Extraction Methods, Static Extraction Methods and manual method.
And J-STD-001F have define ionic residue upper limit value(<1.56 micrograms/cm2) for Static Extraction Methods and manual method. But why not define upper limit value for Dynamic Extraction Methods?
Is there any suggested value for Dynamic Extraction Methods in industry?
