CONSTITUTION:Organic solvent photoresist is coated on base material surface made of Cu or Cu alloy and dried. Next, said material is printed by exposure, then spray development treated to form corrosion resistant film of desired picture. Successively, said material is dipped in aqueous CrO3 soln....

The starting point is a substrate, preferably a dielectric with a patterned copper layer. It features various reference markers and also electrical traces when appropriate. The lower cladding layer, a liquid polymer, is deposited onto the substrate. Depending on the application, the desired layer th...
introduced by several individuals. Such a method waspatentedin 1893, and in 1925 a camera attachment was introduced, making it possible to impart a slight motion to the image on the film and thus reduce exposure to the point at which small highlight halftone dots were not printed or ...

With straightforward instructions, you’ll learn how to cut and stain a plywood frame to resemble a Polaroid, add custom lettering without fancy tools, and construct a sturdy copper frame to bring it all together. Not only is this project cost-effective, but it also results in a one-of-a...
An infrared-light-emitting-diode-based photometer has been developed for use in measuring copper concentrations in hard-chromium and other plating baths. This device provides accuracy comparable to that of more sophisticated techniques, is easy to operate, requires no sample preparation, creates no wa...
