Of course analysis is need to supply data when analyzing processes; however
it's important to chose the correct analysis technique. When it comes to
the small amount of deleterious materials left behind on a circuit after
water washing, weight gain is not a particularly sensitive analysis tool.
IPA/water extraction followed by ion chromatography would provide better
data with regard to materials on the circuit that may cause circuit
failure. Applying elevated temperature and humidity with power on the
circuit to determine whether electrochemical failures occur may also
indicate that a circuit is not clean enough. If a circuit board washed in
tap water with a blow-off passes the temperature humidity power test, then
it's likely that tap water wash is good enough; if not, it might be wise to
use DI water during the wash process.

When it comes to selecting someone to help analyze a company's processes I
will take the "Fresh Out of School" MBA over an experienced electronic
technician any day.
When I asked about rinsing in tap water followed with a water blow off so
many folks said "Must Use DI" without even considering an analysis. A fresh
out of school MBA might think about it longer. Hmmm I think I will pay them
more money.
What would they do in China? Put in a DI system of blow off tap water with
an air gun? Hmmm, sounds like China knows the value of a dollar!

There seems to be two types of MBAs. Those that start with an undergrad
degree and get their MBA as they, and those that get their MBAs before
entering the real world. The problem came in the 80's, when every company
wanted to hire those freshly minted MBAs right out of school. About the
same time that share price became the only barometer. So began a cycle of
formulatic answers because the textbook said so. Profits temporarily down?
Reduce the workforce. Wnat more profits? Send it to China. The MBAs with
real experience knew better, wouldn't go for the instant gratification
ideas, so they aren't the ones who got promoted to positions to make
significant business decisions. Part of the reason American companies seem
to be stuck in a ditch is because we're now starting to see the long term
effects of short term efforts to prop up that share price.
I could show rather convincingly how moving some R&D workforce to China
because they bill 1/3 is costing us twice as much, and losing us market
share. But I don't have the right letters after my name, I don't get to go
to those meetings.
