... demonstrated that polyimide can be removed from large areas, as well as from copper leads and places where circuit patterns are located. Fig. 1 - Raster Pattern. Fig. 2 - Polyimide Removed in a Continuous Line. Comments: Laser skiving has traditionally been performed with shorter wavelength, solid-state ...

... and use of a traditional phototool. In the most common LDI implementation, the front end CAM system is used to modulate a focused laser beam that is raster scanned across the panel. The desired image pattern is built up line by line, analogous to the way in which an image is formed on a CRT display ...

12 . SEPTEMBER 2005 . WWW.CIRCUITREE.COM LDI systems based on raster scanning account for nearly all the current installations for a number of reasons. Historically, raster scanning LDI technology was first developed around 1990, long before practical, high resolution SLMs came into being. As a result ...

... the first to have commercial success. The performance issue mainly concerns scan speed. To deliver completely flicker-free images, a single-channel raster scan system would probably operate at frame rates of up to 300 frames per second (fps). This means a scan rate of up to 900 fps for each color, with ...

... intracavity tripling). Q-switched lasers offer the required high peak power for effi cient frequency conversion, but their pulsed output can't be raster scanned at the speeds required for LDI. Now, a radically different type of solid-state laser has completely by-passed this effi ciency problem. Specifi ...

... both be directly modulated in the DPSS laser. This facilitates grayscale marking and permits flexibility in terms of write speed. Both vector and raster scanning techniques are employed for card marking (figure 2). In vector scanning, the laser beam traces out the marked pattern as a series of lines ...
