To extend the utility of such disposables, it is necessary to provide a low cost manufacturing technology that enables fine structures with high resolution to be produced in high volume.
Laser ablation by mask projection is such a technology for the mass production of conductive fine line structures, which closes the gap between the classical photolithographic processes and the semiconductor technology. Depending on the material used, lines and spaces down to 15 micron for thin metal film (Au, Ag, Cu, Pd) or thin organic layers can be produced. Due to its simple process mechanism, laser ablation combines precision and economic efficiency. In combination with reel-to-reel web-handling the ultimate engineer’s dream comes true: higher performance at lower production costs.
Key words: medical disposable sensors, laser ablation, reel to reel processing.
