20090244510 | PROCESS AND APPARATUS FOR THE PRODUCTION OF COLLIMATED UV RAYS FOR PHOTOLITHOGRAPHIC TRANSFER - The present invention provides an improved process and an apparatus for producing collimated UV radiation for exposing printed circuit boards. The process consists in shortening the optical length of the downstream optics by dividing the UV radiation over many radiation sources, and in distributing the UV radiation uniformly on the substrate by using a scanning slide. | 10-01-2009 |
