Industry & manufacturing
In industry and manufacturing, UV radiation is a production step with a cycle time and a release criterion – from UV curing and bonding through electronics, packaging and optics to vehicle manufacturing. Measurement therefore happens at the least favourable point on the part and during the running process.
Additive Manufacturing
Measurand: irradiance on the part, post-cure dose
Light-based 3D printing cures parts through spatially controlled photopolymerisation – and reaches the final state only in post-curing. The article shows how exposure, post-cure and shadowing on the part are measured.
Electronics & Semiconductor Industry
Measurand: UVC irradiance, dose at wafer and component level
In semiconductor and electronics manufacturing UV serves photochemical cleaning and activation of surfaces and the exposure of radiation-sensitive layers. The article covers both tasks and their measurands in the back-end.
Packaging & Filling Technology
Measurand: UVC dose at the least favourable point of the packaging
UV disinfection of closures, preforms and equipment surfaces replaces chemical and thermal processes in filling lines. The article shows why the dose has to be measured at the least favourable point within the cycle time.
Optics & Precision Components
Measurand: irradiance with defined measurement geometry, UVC dose
For optical precision components the surface is the function. UV removes organic films, activates glass and plastic and cures joints – the article shows how this is measured and documented without contact.
Automotive & Vehicle Components
Measurand: dose profile along the path, irradiance on the part
In vehicle manufacturing UV curing cross-links adhesives, coatings and potting compounds on three-dimensional parts with varying distances and angles. The article shows how dose profiles are measured with robot guidance.
