摘要： Phototools are located for processing both sides of printed circuit board panels by an apparatus and process that utilizes a work station with two alignment fixtures each including panel center registration PCR alignment mechanism to locate phototools and panels. Processing steps utilize the alignment fixtures to locate phototools on both sides of a panel. Each of the two phototools is initially positioned on its alignment fixture by the PCR alignment mechanism and secured to its alignment fixture by means of a vacuum supplied by a vacuum chuck which is operative as the top surface of the alignment fixture. The panel is then placed on top of the first phototool and aligned to the first phototool in the first alignment fixture using the PCR alignment mechanism. This first phototool is then affixed to the first side of the panel. The panel with the attached first phototool is then placed on the second phototool in the second alignment fixture and aligned to the second phototool using the PCR alignment mechanism. The second phototool is then affixed to the second side of the panel. The phototool-panel-phototool package is then placed in a printer for exposure.

摘要翻译： 摄影工具位于通过一个装置和工艺来处理印刷电路板面板的两侧，该设备和工艺利用具有两个对准夹具的工作站，每个对准夹具包括面板中心对准PCR对准机构来定位照相工具和面板。 处理步骤利用对准夹具来定位面板两侧的照相工具。 两个照相工具中的每一个最初通过PCR对准机构定位在其对准夹具上，并通过由作为对准夹具的顶表面的真空吸盘提供的真空固定到其对准夹具。 然后将面板放置在第一光学工具的顶部上，并使用PCR对准机构与第一对准夹具中的第一光学工具对准。 然后将第一张照片固定到面板的第一侧。 然后将具有附着的第一光固版的面板放置在第二对准夹具中的第二光学工具上，并使用PCR对准机构与第二光学工具对准。 然后将第二张照片固定到面板的第二侧。 然后将照相工具 - 面板照相工具包放置在用于曝光的打印机中。

摘要： A metrology system to analyze panel misregistration in a panel manufacturing process includes a software controlled system which checks defined panel parameters on the four corners of a panel and related artwork for processing with a master pattern etched on a glass reference with a machine vision measuring system. The panel or artwork being checked is positioned by panel center registration means to align the center of the panel with the center of the master pattern. Displacement and rotational differences are entered under software control into a data base and analyzed by a stored program intelligent analyses system into a plurality of parameters based on a parameter model which permits an analysis of the cause of the misregistration.

摘要： A panel locating method engages holes in a panel which are located in the panel symmetrically about a fixed point and axis and applies synchronized opposing displacements of engaging elements to locate and secure the panel on a work surface.
