Association Connecting Electronics Industries K Grinsteinner 2005 60 Hibbing workers lose jobs; Noble Industries closing down Mesabi Daily News, April 27 THE PRINTED CIRCUIT TECHNOLOGY INDUSTRY 15 cost regions in Asia, Eastern Europe and Latin America."8 Sanmina-SCI purchased Pentex Schweitzer in 2004, and in doing so, bought PrCB manufacturing capacity with one plant in Singapore and two facilities in China.9... U.S economy Semiconductor technology performance continues to double every 18 months,7 and most semiconductor chips require packaging that includes some form of interconnecter such as a printed circuit board The increasing globalization of the electronics industry has driven the capability to manufacture interconnection technology overseas.8 The intense competition in the face of this increasing globalization... global component Only in the past 4 years, however, has the U.S manufacturing base faced a serious decline The decline is continuing as the remaining larger companies close facilities and increase their investment in China and in other lower-cost manufacturing locations In 2000, the United States was second only to Japan in production of PrCBs, and these two countries had swapped the lead position at various... paper-base printed boards and multilayer polyimide printed boards BOARD DESIGN The main function of printed boards is to support and interconnect the electronic components mounted on them; they may also serve to dissipate heat and protect components The base materials, wires, and wire layers vary widely; design decisions are made according to the specific requirements of the application Constraints include... function of a printed circuit board (PrCB), simply, is to connect a variety of active components (such as microchips and transistors) and passive components (such as capacitors and fuses) into an electronic assembly that controls a system A typical printed circuit board consists of conductive "printed wires" attached to a rigid, insulating sheet of glass-fiber-reinforced polymer, or "board. " The insulating... the following areas: • • • • • • • Government, military, and aerospace uses; Medical devices; Automotive electronics; Computers and business electronics; Consumer electronics; Industrial electronics and instrumentation; and Communication Today, interconnecting electronics in increasingly complex systems is leading to complex designs, components, and systems The advent of integrated electronics, such... sales.3 A growing sector in electronics manufacturing is in the contract manufacturing of electronics manufacturing services (EMS) EMS has become a major component of the electronics industry in the past 5 years This migration is less true for the PrCB industry Only one electronics manufacturing systems company, Sanmina-SCI, is vertically integrated and manufactures PrCBs The rest of the EMS industry buys... regulations Because many companies supply components worldwide, they are finding the cost of producing two types of printed circuit boards, both with and without lead, to be a poor business proposition Challenges in Supply-Chain Management Outsourcing and offshoring are growing trends with dramatic effects on supply chains and supplychain management Within these trends, supply chains are also evolving... Congress, and the federal government lack a clear understanding of the importance of high-quality, trustworthy printed circuit boards (PrCBs) for properly functioning weapons and other defense systems and components This report of the National Research Council's Committee on Manufacturing Trends in Printed Circuit Technology aims to illuminate the issues related to PrCBs for military use In addition, this . Committee on Manufacturing Trends in Printed Circuit Technology Board on Manufacturing and Engineering Design Division on Engineering and Physical. Council convened a panel of experts—the Committee on Manufacturing Trends in Printed Circuit Technology to examine trends in electronics interconnection technology
