PRINTED CIRCUIT BOARDS

This category includes establishments primarily engaged in the manufacture of printed circuit boards, sometimes referred to as printed wiring boards.

A printed circuit board (PCB) is a thin piece of insulating material onto which tiny electrical wiring pathways or "traces" have been printed, usually by a photo-engraving process. PCBs provide the physical structure for mounting electronic components, such as semiconductors. The printed traces then serve to interconnect the components, forming an electronic system. PCBs are used in a wide range of electronic products, including computers, telecommunications equipment, electronic instruments, and automobiles.

Industry Snapshot

In the late 1990s, more than 1,300 U.S. facilities shipped printed circuit boards worth $9.1 billion. By 2000, the value of shipments had increased to more than $12 billion. The total number of industry employees grew steadily throughout the late 1990s, rising from 72,282 in 1997 to 84,018 in 2000.

Organization and Structure

According to the IPC, approximately 650 independent companies produced PCBs in the United States in 1997, accounting for 90 percent of the entire market. So called "captive" PCB-makers, primarily large original equipment manufacturers (OEMs) that make their own boards, comprised the remaining 10 percent. Though the largest market for OEM...
