We do not. However, we clean our boards post process. If you have a no clean
process, and high rel service environments I would recommend testing, in a
COC from your supplier, or a lot sample internally.

Subject: [TN] PCB Cleanliness Via Ion Chromatography Poll (informal)
I actually sent this out on May 16th, but never got a single response.
Hoping that was not due to lack of interest, but rather due to the TechNet
being down. Hence, I think I'll try this one more time.
I am hoping to run an informal " min straw poll " here.
Questions stated are as follows:
1. "Is your organization testing incoming PCB cleanliness via ion-
chromatography? Replies such as "YES" or "NO" will suffice, but
more detailed explanations are also acceptable.
2. " If testing via IC, do you use IPC -5704 Table 4.1 limits or
other? Replies such as " IPC"
or "other" will suffice, but more detailed explanations are also
acceptable.
What's in it for you? I will summarize and post the results after a few
days of replies.
