Look, Dad—They print wires now!

In a wide variety of electronic wonders—from hearing aids to guided missiles—printed wiring, etched from paper-thin Anaconda “Electro-Sheet” Copper, saves space, time, and money.

Remember the time you tried to fix the radio?

Inside you found a maze of wires. You hustled it down to the corner repair shop. It was no job for a novice.

Look in some of today’s radios. The wires are gone—or seem to be. They are printed!

HOW IT’S DONE Very thin copper—called “Electro-Sheet”—is bonded to a plastic laminate panel. On this copper sheet you print the wiring circuit you want with an ink that resists acid. Then you etch away the unwanted metal, leaving the pattern intact. This type of circuit is far superior to wires. It is accurate, compact and stable. Next you snap-fasten tube sockets and other parts in place and dip-solder the connections. To make a hundred electrical connections this way takes only a few seconds.

With printed wiring and other devices—such as transistors—electronic experts are concocting match-box-size hearing aids, vest pocket radios, more compact TV sets and portable electronic “brains.” They are speeding up the production of precision instruments vital in the operation of aircraft and control of guided missiles.

WHERE THE COPPER COMES FROM “Electro-Sheet” was developed and is made only by Anaconda*. Down at the Raritan Copper Works of the International Smelting and Refining Company (an Anaconda subsidiary) at Perth Amboy, N. J., production engineers turn it out in a wide range of thicknesses, as thin as one-thousandth of an inch as thick as this page) and in five-foot-wide rolls thousands of feet in length.

Besides printed circuits, Anaconda “Electro-Sheet” is ideal for a wide range of electrical applications such as static shielding, contacts and capacitors. Builders use it as an easily applied concealed flashing, an efficient vapor barrier and for economical waterproofing (see photo above).

There are dozens of other uses—gaskets, cable wrapping, hydrogen-furnace brazing metal, utility-pole capping, to name a few. Because so many new jobs are being found for “Electro-Sheet,” Anaconda is making more and more of it.

To provide the copper for “Electro-Sheet,” and thousands of other copper, brass, and bronze products, Anaconda has developed vast new ore bodies and has expanded production capacity from mine to finished products.

There will be plenty of copper. On the drawing boards of peacetime U. S. industry, copper has the green light— for years and years to come.

    Just wait until they start printing on a silicon chip…….that kid hadn’t seen nothing yet….

    So…you’re suggesting printed circuits are easier to repair than point-to-point wiring?

    Oh, and that’s one sweet radio he’s holding:

    @2 yeah that story sort of didn’t go anywhere, i don’t think they’re suggesting that though that would be pretty crazy huh
