December 27, 1965 Electronics Cover - RF Cafe[Table of Contents]

Wax nostalgic about and learn from the history of early electronics. See articles from Electronics, published 1930 - 1988. All copyrights hereby acknowledged.

Raise your hand if you're old enough to remember doing printed circuit board (PCB) layout using Rubylith tape. My hand is up. Back in the early 1980s, I did prototype PCB designs in an engineering development lab at Westinghouse Electric's Oceanic Division (Annapolis, Maryland). Most of it was for analog and RF substrates that would be photographically reduced in size for use with bare integrated circuit (IC) die and surface mount passive components (Rs, Ls, and Cs), upon which I would later epoxy-mount those components and wire-bond everything using 1−mil gold wire. However, there were projects where full-size leaded components were used on a through-hole PCB that used not only the Rubylith tapes but also sheets with special electronics shapes for solder pads around the holes for components leads, ground and power planes, board-edge connectors, turrets, etc. Computer-aided PCB layout was in its infancy at the time, and the proprietary software used for commercial operations ran on a mainframe. I do remember, though, sometime around 1985 using some really clunky PCB layout software on an IBM XT, but never actually produced a board from it. I don't remember the name of the software.

Here's How...

Lithographers, Engravers, Artists, Screen Processors All Use These Famous Masking Films to Separate Color, Eliminate Opaquing, Prepare Dropouts, Save Time, Reduce Job Costs

Cut a piece of the desired film large enough to cover area to be masked. Tape it down firmly at the top with dull-side up.

With sharp blade, outline the areas to be masked. Do not cut through the backing sheet. The Ulano Swivel Knife does the job quickly, easily.

Now carefully peel off the film. Your art work is now separated with the "second color" on a clear Mylar overlay ready for camera and in perfect register.

Rubylith™ • Amberlith™

Hand Cut Masking Films for the Graphic arts

Ulano Rubylith... a revolutionary knife cut red film is laminated to a stable transparent plastic backing sheet. The red film is "light safe" so that when contacted to a sensitized emulsion and exposed to a suitable light source, light passes through the cut-out portions only ... not through the red film. • The mylar* backing is absolutely stable ... insures perfect register. • Special effects such as crayon tones, paste ups, benday sheets, and opaquing are easily combined with versatile Ulano Rubylith. *T.M. Dupont Polyester Film

Ulano Amberlith ... a companion to Rubylith serves as a color separation medium used as the master on camera copy board to secure negatives or positives.

Available in Rolls and Sheets

About RF Cafe

Kirt Blattenberger - RF Cafe Webmaster

Copyright: 1996 - 2024


    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
