San Jose, Calif. – FlexTech Alliance today announced the successful conclusion to its Large-Area Roll-to-Roll In-Line Surface Metrology Program with 4D Technology Corporation of Tucson, Arizona. The product, the FlexCamTM Defect and Roughness Metrology Module, was launched to substantial interest in February at 2015FLEX in Monterey and will be featured in several upcoming events. This project was started in 2012 with the intent of developing high-speed inspection and measurement — two important measures of success in roll-to-roll manufacturing of electronics.
The project started with a request from FlexTech members for an inspection system which could provide insight into the characteristics of a web in motion. 4D Technology proposed, and was accepted to complete, the project. Important characteristics included: freedom from vibration of the rest of the system, detection of surface roughness in the 1 nanometer range, web speeds up to 1 meter per minute, and a field of view of 4 millimeters. The company’s final product has exceeded several of the original technical targets and has demonstrated the expectation for further improvement. Originally intended for barrier film manufacturers, the FlexCam is also gaining interest for characterizing substrates and intermediate layers. Interest has also been seen in other market areas, including non-roll-to-roll applications, precision optics manufacturing, and in place measurement of roughness on polished metal parts in precision machining centers.
