This paper introduces FocalSpec’s recently patented optical Line Confocal Imaging (LCI) technology that was developed to measure 3D features of various surface and material types at sub-micron resolution. LCI enables automatic microtopographic scanning of challenging objects that are difficult or impossible to measure with traditional methods. Examples of such products include glossy and mirror-like metal surfaces and transparent polymer films and sheets. LCI can be used to measure fast-moving surfaces in real-time as well as stationary product samples in laboratory.
Operational principle of the LCI method and its strengths and weaknesses are discussed. Three potential applications for LCI sensors on flexible and printed electronics products are examined:
1. 3D conductor trace width and cross sectional trace profile measurement.
2. Surface roughness measurement for monitoring Ra/Rz value of copper surfaces.
3. Ink thickness measurement in printed electronics applications.
