Latest Patents
Tetz's latest patents include a "Method and apparatus for aligning phototools for photoprocessing of printed circuit board panels." This invention involves a sophisticated work station equipped with two alignment fixtures. Each fixture utilizes a panel center registration (PCR) alignment mechanism to accurately position phototools and panels for processing on both sides. The process ensures that each phototool is securely affixed to the panel using a vacuum chuck, allowing for precise alignment and exposure in the manufacturing process.
Another significant patent is the "Metrology system for analyzing panel misregistration in a panel manufacturing process." This system employs a software-controlled mechanism to check defined panel parameters at the corners of a panel. It utilizes a master pattern etched on a glass reference and a machine vision measuring system to analyze displacement and rotational differences. The data collected is then analyzed by an intelligent system to identify the causes of misregistration, thereby improving the overall manufacturing process.
