🧾 Overview
Feedback from module loading during production is essential to understand which QC parameters are critical. This helps to refine, simplify, or adapt the module QC procedures.
This section collects the main topics currently under investigation based on observations from Outer Barrel (OB) module loading.
🧼 Module Backside Cleanliness
Impact of Parylene on Sensor Side
Status: Under evaluation
Investigations are ongoing to assess the impact on loading of potential contamination or impact due to parylene presence on the sensor-facing side of modules observed by some module QC sites
Impact of Vacuum Jig
Status: Under evaluation
Studies are examining whether the marks/residues left by vacuum jig used during module QC is an issue for loading
📏 Module Backside Flatness
Impact on Cell Conductivity
Status: Under evaluation
Possible correlation between backside flatness and proper connectivity/conductivity in loaded cells is being studied.
📊 OBWBP Electrical Resistance and Noise
Latest Observations (Reported by Susanne Kuehn, 28/07/2025)
- A correlation study was performed between noise and canopy resistance on the first pre-production longeron.
- All modules used had resistance values below 60 Ohm.
- No strong correlation was observed in this first dataset. Since no high-resistance module was present, conclusions are still limited.
- Two additional pre-production loaded local supports will be assembled in August–September 2025, using modules from all production sites. These are expected to provide more comprehensive insights.
