Operating procedures

Image Modified	Mixing SE4445 cartridges for storage This page describes how to set up and mix SE4445 into smaller syringes for later use in the B33 cleanroom complex gowning area.
Image Modified	Building 33 - Glue freezer monitoring setup Page describing the setup of the LabJack 7 + thermocouples, as well as monitoring software, PC setup, network setup. Frozen glue log [archived]
	Dispensing SE4445 Step-by-step procedure for using the Nordson dispenser and robot in B33 to deposit SE4445 in a star pattern.
Image Modified	Advanced: Programming concepts in Janome Points for the glue dispensing robot We can only predict so many eventualities: This page describes how to create your own custom Janome Points program file. It breaks down some key concepts (like Janome jargon "Point Job," "PTP," and "palette") as well as how to set up the Janome Points programme.
	Running the CMM Describes how to operate the CMM in the small clean room in B33
	Rework procedure Using fishing line and ethanol, we can remove heaters from staves. [Confluence]

Analyzing glue dispensing performance

	Coverage	Glue layer thickness
Purpose	Determine the area of the glue layer beneath a module as a percentage of the module area	Determine the thickness of the layer of glue underneath the module
Target range	75-85%	75-125 microns (ATLAS specification: 100⁺¹⁰⁰_-50 microns)
Measurement strategy	Extract glue layer area from images collected of samples on a clean, solid, high-contrast background. Please note that a ruler or other clearly known dimension must be in the image frame to provide a pixel-real world coordinates calibration source.	Height gauge measurements
Analysis resources	Charlie created a MATLAB script for measuring coverage in images of dispensed samples collected on a clean white background. Alternatively, we can extract these areas with image processing tools like ImageJ.	Hannah and Rachel prepared Python-based scripts to analyze csv files containing height gauge measurement results. The (messy) scripts are available on GitLab: https://gitlab.cern.ch/hherde/slacpixelsanalysis
