晶圆加工、检测和识别
晶圆又称切片或基材，是光电电池制造中使用的半导体材料薄片，负责将光转换为电。机器视觉可使晶圆加工自动化；实现精度校准；检查母线槽和 AR 涂层以形成薄而高质量的精确栅距晶圆。质量检测可帮助制造商减少晶圆扭曲、翻转、碎裂、含有锯痕或整体外形缺陷。

Solar PV Module Assembly
In the final step, many PV cells are assembled into strings and packaged into a single unit, called a module. Machine vision ensures accurate cell spacing, construction, and part placement during module assembly. During stringing alignment and inspection, machine vision centers the PV cells, minimizing the need for mechanical contact, and examines the cells for defects while also verifying the continuity and correct assembly of each string. Multiple modules may be assembled into a solar panel.
Wafer-to-Package Traceability
Industrial image-based barcode readers handle even degraded, reflective, or low-contrast marks from die backsides, substrates, encapsulated packages, and PCBs for complete traceability. Barcode readers reliably track parts and identify wafers, PV cells, and modules throughout production and assembly.
Ingot Formation
Cognex machine vision products monitor ingot formation, providing precise dimensional measurements during the crystal pulling process. The In-Sight 8000’s small form factor and robust edge detection tool ensure the crystal seeding, shouldering, shoulder circuiting, and diameter equalizing stages are performed to exacting standards for proper ingot formation.
