Simultaneously, the continued pressure on manufacturing costs requires Tiffany Elsa Peretti Teardrop drop earrings advances in equipment performance be coupled with lower cost of ownership through such key factors as throughput, yield, and use of conventional photoresists.There are two primary drivers for the push in development of new imaging systems. The first is the recognition by the global Tiffany Elsa Peretti Teardrop Earrings fabrication community of the fact that current tools are at the end of their capabilities. The second and equally important driver is the assessment by industry experts that the limitations of current tools are fundamental; evolutionary advances in the tools that result in marginal improvements will no longer be sufficient to Tiffany Elsa Peretti Teardrop necklace the demanding manufacturing requirements. Contact printers can have low yields due to defects produced in the board and low mask life, and there are also risks of poor alignment performance and off-contact problems due to nonplanarity of board surfaces. Because exposure can be done only after the board Tiffany Cushion mask are brought in hard contact, whereas the relative positioning between them necessary for precise alignment must be done before the contact, high-precision board-to-mask alignment becomes an issue. Contact printers also use very high-power arc lamps, including inefficient provision of UV radiation, the need for enormous heat filtering, vibrations and thermal distortion, and poor resolution. These limitations are eliminated in LPI. LDI systems do not require a mask (i.e., artwork), therefore the aforementioned artwork-related issues disappear.
