The throughput value of 125 boards/ hour is realized with the Tiffany Elsa Peretti Teardrop bracelet system for any photoresist with a dose requirement of 120 mj/cm2 or less. For resists that require exposure doses below 120 mj/cm2, the system attenuates the laser beam to use lower power because the throughput-limiting parameter is the maximum stage scanning speed of 500 mm/sec. For resists requiring doses above Tiffany Elsa Peretti , the proper exposure is obtained by scanning at speeds below 500 mm/sec; the maximum laser power thus becomes the limiting factor. For example, for exposure doses of 150, 300, and 500 mJ/cm^sup 2^, respectively, exposure times will be 23, 47, and 78 seconds and the net throughputs will be 108, 64, and 41 boards/hour. There are Tiffany Elsa Peretti Teardrop drop earrings technologies available that further enhance the LPI systems for high-volume manufacturing of fine-line printed circuits. The first is variable-area substrate tiling, which enables the system user to rapidly and flexibly configure the partitioning of the board to pattern modules of different sizes, while Tiffany Elsa Peretti Teardrop Earrings deriving the major cost benefits of large-format processing. The second enhancement is anamorphic x-y scaling, which provides independent image size adjustment along ? and y to compensate for dimensional changes in the panel that may occur during any processing steps. Due to space limitation, we will describe these additional system features in a forthcoming publication.
