Nowwere using anywhere from 9 to 16, and there are newcircuits with 18 to 20 on the way. It makes the testingjob that much more complex. It also makes it thatmuch more difficult to develop a working productionline process. The more complicated and delicatethese things get, the bigger our job is. With wholecircuits, youre speaking a different language. With new designs arriving from the DCL at todaysaccelerating pace, Mr. Santanginis human engineer-ing is important. People here enjoy working withnew things, he points out. They cant be bothered. 23 Working interface between Bell Laboratories and WE: on the design capability line at Allentown — the step between design and pilot line — Western development engineer Robert Whitner, left, and Bell Laboratories Paul Perron determine if newly designed products will be amenable to manufacture. Today its beam lead integrated circuits, says Mr. Perron. Tomorrow it may be something else, requiring different materials, different methods and equipment. Whatever it is, it will require continuous coordination between research and manufacturing.
