Hit one number. Before it moves.
JUMO makes platinum temperature sensors. Each must hit an exact resistance.
Case study 01 / 09
A model that recommends the laser correction for platinum temperature sensors at JUMO, served with an audit trail an operator can trust.
01
JUMO makes platinum temperature sensors. Each must hit an exact resistance.
02
Printing and selection shift the resistance afterwards. The correction has to predict that.
03
Eight files that shrink stage by stage. One blind merge would have lied.
04
294 substrates broke before sputtering. 8,000+ had no order. One ID read 9.22E+18.
05
Some sensors are trimmed twice. The target is the last correction in the clean room: NCTr.
06
The first run looked brilliant, on the wrong target. We went back.
07
RMSE 0.1044 → 0.0202. 99.63% inside ±0.1 tolerance.
08
A parser reads type, geometry and resistance straight from the part number.
09
Model version, AI label and inputs are saved with each recommendation. The operator decides.
10
Framing, the source inventory, join audits, trust controls, the part number parser, the NCTr fix and the end to end test.

An explanation for every recommendation, and an alert when the line changes.
