Bonding With Infrared Energy A new technique that makes it possi-ble to bond simultaneously large num-bers of flexible cables to printed cir-cuits or to other cables has been de-veloped jointly by Bell Labs and West-ern Electrics Engineering ResearchCenter at Princeton, New Jersey. By using focused infrared energy tosolder the cable, the new techniqueprovides a quick, easy and inexpen-sive method of interconnecting circuitboards such as those containing min-iaturized solid state components usedin computers and communicationsequipment. Until now, connecting flexible cablerequired complicated preparation andeach conductor had to be solderedindividually. With the new process,fifty or more connections can be madein 10 A. p. Boyer of Bell Labs inspects new infrared soldering device as it bonds flexible cable toprinted circuit board. With this process, 50 or more connections can be made simultaneously. 17 A Seller: Market Some 45,000 companies, most of themsmall businesses with less than 500employees, sold more than $ bil-lion in goods and services to the BellSystem last year. The sales were made to WesternElectric, which acts as the purchasingagent for Bell companies. Purchaseswere made from suppliers in all 50states and in 21 foreign countries andterritories. In the , the purchaseswere spread over some 4,000 com-munities. Copper was again the major rawmaterial purchased — $130 millionworth — while telephone directorieswere the principal supply item boughtby Western. The total bill for the lattercame to more than $90 million. Laser Knife Developed A new light knife which allows sur-geons to use the focused beam of alaser as easily as they would a scalpelhas bee
