IPC J-STD-001E Ionic Cleanliness Standard | 30 August, 2013

IPC-J-STD-001E in regards to Ionic Cleanliness standards states less than 1.56 µg/cm² of total NaCL.

Assuming a typical electronic process which involves smt, wave, and post-hand soldering and uses NO-Clean flux throughout all process, is it typically possible for electronic mfg companies to meet the IPC requirements of less than 1.56 µg/cm² of total NaCL without having to implement a cleaning process?

Yes, providing your:
* Inbound material does not compromise your process.
* Soldering processes apply the proper amount of flux and activate it properly
* Material handling does not contaminate your boards

Recognize that the IPC requirements of less than 1.56 µg/cm² of total NaCl is an anachronism based on rosin flux.
