Few industries have changed as radically and as rapidly as the electronics industry. In fact, the technology practiced today draws upon specialties that simply did not exist when man- ufacturing began at Reading. Diffusion technology, ion im- plantation, thermocompression bonding, thick film technology, epitaxial layering, beam lead interconnection, and laser etch- ing are just some of the pro- cesses that have challenged the ability of our engineering staff in this new age of electronics. To meet this challenge, our en- gineers must he drawn from many different disciplines in- cluding electrical, chemical, 100 years history.

So, a Western Electric engineer's training doesn't stop when he graduates from college; in fact, it's just beginning. Our Corporate Education Center, located near Princeton, New Jersey, and our Summer on Campus Mas-ter's Program are only two ways that education continues. More importantly, it occurs on the job, where engineers interact daily with their peers, technicians, and other professionals from a wide variety of backgrounds, as well as the techni-cal/professional employees in Bell Laboratories, Together, WE manufacturing engineers and research engineers and scientists strive to improve the new and existing products upon which a reliable communications network depends. Engineers are involved in all aspects of our business from planning process and product development, to facilities engineering. Their diverse backgrounds and interests come together to meet the challenge of our ever-changing world.

6 quality and reliability. Quality control is twofold: throughout the manufacturing cycle, indi- vidual devices are inspected at critical points and the processes and machinery used to produce them are also inspected. This in- process checking is designed to discover, correct, and prevent product defects at their points of origin. To ensure that quality is built in, everything that touches our products, even the one mil- lion gallons of water we use daily, must be free of im- purities. Just as we constructed clean rooms to provide clean air. we also constructed a water treatment plant at our location to provide clean water. Many of the operations performed at the Works require that chemicals be rinsed off products. A spot of residue from regular drinking water would block out critical portions and functions of an in- tegrated circuit chip. In fact, our products need even cleaner water than the human body does. If one million pounds (120,000 gallons) of good drink- ing water were evaporated, it would leave behind about four hundred pounds of residue. Yet, if the same amount of water we use were evaporated the same way, less than one pound of res- idue would remain. Not only is the water treat- ment plant's input to the Works clean, its output is even cleaner than the water it joins from local streams and springs. The plant treats about a million gallons of water per day. helping our local community keep our water- ways free of pollution. Our em-ployees are proud of the water treatment plant, which was cited by the Environmental Protection Agency (EPA) as a model plant for the electronics industry. In addition to providing a quality product to our customers, the Reading Works is com-mitted to providing a quality work environment for our em-ployees. As the record shows, the Reading Works is a clean, safe place to work.

It means that production employees can go to a terminal to find out which product groups to work on and to obtain in- structions as to which process steps should be followed For engineers it means keeping track of product information from the design stage through manufacture. And accountants use computers to develop fore- casts and results and in the many day-to-clay financial oper- ations, inherent in a business enterprise of the Reading Works' size.

Bell Labs has proved the value of long-term investment in research and development – not only for telecommunica- tions, but for society as well.

13 Reading People

Employees at the Reading Works come from a wide variety of backgrounds and reflect a broad range of interests. During their free time, Reading people are involved in a number of di- verse activities ranging from hobbies and community service to competing in world class running and championship chess. Their jobs here are just as varied as their personal inter- ests and all play an important role in maintaining the Reading Works' leading-edge position in the telecommunications Indus- try.

14 15 16 17 Pioneers

Working, taking care of a family, and participating in re- ligious and social activities is enough to more than fill the av- erage person's life. But Tele- phone Pioneers aren't "average" people. They are people with energy, purpose, and a dedica- tion to helping others. The Telephone Pioneers of America is an association of telephone industry employees and retirees with more than half a million members world- wide. Thanks to their large membership and high degree of activity, local Reading Works and BTL Pioneers became the Laureldale Chapter in 1982, after serving more than twenty years as a Council. Pioneers are continually in- volved in new and on-going community service projects. One recent innovation, designed by a BTL Pioneer, is a playback re- corder which tapes sounds and automatically plays them back.

19 Community Involvement

Take a look into any organi- zation of people helping their community, school or church, or their neighbors, and you'll surely find a Reading Works employee representing WE or volunteering his own time to help get the job done. Western Electric demon- strates its commitment to the youth of the community by sponsoring Junior Achievement. an organization designed to help young people better understand the free enterprise system and an Explorer Scout Post. which encourages young people with interests in electronics. In both these groups, employees serve as advisors. Taking volun- teerism one step further, the Explorers often choose a project which makes a meaningful con- tribution to the handicapped. The Reading Works also re- sponds to the needs of youth by accounting, construction, and member agencies. Whether it's offering a "Careers" program to labor relations.
