Machine vision company Isra has announced its Solar Vision 3D technology for surface inspection and geometrical gauging at the printing process stage. In addition to the existing inspection and measuring functions of Isra's Solarscan front print and Solarscan rear print systems, the new 3D option allows the detection of splinters and other height relevant structural defects.
Cell manufacturers benefit directly from implementation of the new inspection technology through significantly higher machine uptimes and reduced cell breakage. In total, Isra says, this enables an increase of high-quality yield and the reduction of manufacturing costs, because 100 per cent inspection is carried out.
In addition to the two-dimensional surface images, 3D inspection provides important additional information for structure and topography. The result for print inspection is the detection and classification of height related defects such as splinters or particles. And a significant increase of measurement accuracy, such as for wafer bow gauging.
These new features, in combination with the existing inspection functions, allow for production quality and a secure print process. The Solarscan systems with the 3D option support the latest production technologies such as metal wrap through. As a result, cell manufacturers no longer have to fear the increasing risk of cell breakage. The return on investment on the single systems is under four months.
