Same bath. Same process sheet. Same setpoints.
One production load passes.
The next one doesn't.
If you've spent years around plating lines, you know this situation.
And this is where “the process was the same” can become a dangerous assumption.
A process sheet tells us what was supposed to happen.
It doesn't necessarily tell us what the part actually experienced during deposition.
A small difference in loading density, rack position, electrical contact, effective plated area, surface condition, current distribution, bath history, or operating conditions can change the outcome.
So when a good load and a defective load come from the same process, the first question shouldn't always be
“Which parameter is out of specification?”
Sometimes the better question is
“What was different between these two loads?”
Compare the good load against the defective load.
Look at the part.
Look at the rack.
Look at the loading.
Look at the electrical conditions.
Look at the bath history.
Then look at how these variables interact.
Because in electroplating, identical setpoints do not always mean identical deposition conditions.
And for a plant, variability doesn't stop at the tank.
It can become rework, lost capacity, lower FPY, higher cost, and delivery risk.
At 𝗚𝗔𝗟𝗩𝗔.𝗔𝗜, we're building engineering intelligence to help teams connect process context, historical information, defect evidence, and technical knowledge so engineers can investigate variability more systematically.
The goal isn't just to produce one good load.
It's to understand what makes the good load repeatable.
When one load passes and another fails, what is the first thing your team compares?
