Hi Richard,

We do not test for cleanliness on incoming PCB's. Probably because we've
never run across any issues due to incoming PCB cleanliness, and
secondarily at anywhere from $10,000 - $30,000 (used) we do not have the
resources to purchase such a piece of equipment.

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.
