Late one evening, just before the approaching holiday season, our Head of Software Development Masa heard a knock on the office door. To his big surprise, there was one of the Santa’s elves with a pair of skis. The elf was invited into the visitors’ showroom where he told Masa that he needed some help with Santa’s skis.

The skis need to be in top shape for Christmas because not every house can be reached by the reindeer sleigh, especially if the snow is soft and deep. Now the skis did not glide as smoothly as they should and Santa wanted to find out the reason for this.

Masa was so excited and more than glad to help Santa in his important work and so he measured the skis with UULA. The 3D images showed that there were some scratches and burned areas in the ski bases that don’t absorb wax. Masa suggested to the elf that he takes the skis for stone grinding.

The next evening, the elf returned with the skis and Masa measured them once more. Immediately, they both saw the effects of grinding in the 3D images. Later, Masa sent the elf a detailed report including measurements before and after grinding.

Masa just learned that Santa had been very happy not just with his fast gliding skis but also with the report Masa provided. Each elf has at least a dozen pairs of skis and they need to be inspected every winter which is why Santa is now looking for someone who can build a quality inspection line with FocalSpec sensors at his ski workshop.

The skis were measured with 3D Line Confocal Scanner UULA, equipped with a LCI1201 sensor.

The next level of metrology for consumer electronics manufacturing

FocalSpec, a supplier of 3D Line Confocal Imaging (LCI) sensors and systems is highlighting its unique technology combining 3D topography, 3D tomography and 2D grayscale intensity imaging at VISION trade fair in Stuttgart, Germany, 6-8 November 2018.

3D topography imaging is typically utilized in component assembly inspection and online quality assurance in consumer electronics manufacturing. In addition, the 3D topography is suitable for surface inspection and roughness measurement on various types of material which include mirror-like, shiny, glossy and transparent samples with surface angles of up to 20 degrees. In case of higher angles, such as 3D curved glass, the sensor or the sample should be tilted or illustrated with another FocalSpec sensor.

The combination of 3D tomography and 2D intensity imaging can be used for identifying defects such as delamination, scratches or dust on the surface or inside the transparent material. Contrary to various other types of imaging systems, FocalSpec technology helps not only seeing the place of the defect and identifying in which layer of the sample the defect is. Also, the dimensions including depth of the defect can be detected.

FocalSpec offering for consumer electronics manufacturing

The imaging speed and accuracy vary depending on the LCI sensor most appropriate for the purpose. The most accurate sensor reaches up to 10nm imaging accuracy and the fastest scanning applications perform with the speed of 5000Hz. The amount of measurement points in one measurement line per second is 2048, independent of the sensor type selected.

The FocalSpec range of LCI sensors is available for all third-party developers and systems integrators. FocalSpec 3D Line Confocal Scanner UULA includes ready-made calculation and analysis for the most typical 3D dimensions measurements. The SDK (Software Development Kit) provided with FocalSpec LCI sensors can be utilized by any experienced software developer or integrator for further online application development. Supported software languages include C+, C++, C#, Labview, HALCON, OpenCV and Python. The supported operating systems include various distributions of Linux, and Microsoft Windows versions 7 and newer.

FocalSpec will demonstrate their sensors’ capabilities in Hall 1 Stand 1J15 at VISION trade fair.

FocalSpec to establish subsidiary in China

FocalSpec, the leading manufacturer of optical 3D measuring devices, is responding to the continuous growth in demand in Asia by establishing a subsidiary in China. The new company will be created through FocalSpec’s merger with its current distributor in China. FocalSpec’s headquarters will remain in Oulu, Finland, and the company will also continue to grow the personnel in Finland.

In 2017, more than 1.5 billion mobile phones were sold around the world. The majority of them were either manufactured or assembled in China. Fifth-generation mobile networks and wireless communication systems, as well as the development of ever lighter and thinner mobile devices, increases the quality requirements for the manufacturing industry and the demand for the solutions of FocalSpec.

To meet its customers’ needs, FocalSpec provides Line Confocal Imaging sensors (LCI), which are able to measure mobile device parts made of glass and ceramic materials, among other things. This is something that continues to be a challenge for competing measuring devices.

FocalSpec’s new CEO Harri Leinonen says the company has ambitious growth targets: “After many years of hard work, we have reached a point where we have several industry-scale projects, which will make it possible to multiply our sales over the next few years. FocalSpec’s LCI technology is also being used in other industries, but over the next few years, the biggest growth is likely to be generated in the electronics industry.”
