A printed circuit board (PCB), also called printed wiring board (PWB), is a laminated sandwich structure of conductive and insulating layers, each with a pattern of traces, planes and other features (similar to wires on a flat surface) etched from one or more sheet layers of copper laminated onto or between sheet layers of a non-conductive ...
One of the largest deliberate PCB spills in American history occurred in the summer of 1978 when 31,000 gallons (117 m^3) of PCB-contaminated oil were illegally sprayed by the Ward PCB Transformer Company in 3-foot (0.91 m) swaths along the roadsides of some 240 miles (390 km) of North Carolina highway shoulders in 14 counties and at the Fort ...

A via (Latin, 'path' or 'way') is an electrical connection between two or more metal layers of a printed circuit boards (PCB) or integrated circuit. Essentially a via is a small drilled hole that goes through two or more adjacent layers; the hole is plated with metal (often copper) that forms an electrical connection through the insulating layers.
General structure of a PCB. Polychlorinated biphenyls (PCBs) are various biphenyl based artificial products that are widely used as a dielectric fluid, industrial coolant, and lubricants in the 1960s and 1970s. There is no evidence its synthesis occurs naturally. They are classified as persistent organic pollutants.
TTM Technologies, Inc. was founded in 1998 by Kent Alder in Redmond, Washington, [3] via an acquisition of Pacific Circuits, Inc., and moved to Santa Ana, California, in 1999, after acquiring Power Circuits, Inc. [4] Alder was previously the president of Lundahl Astro Circuits, Inc. in Logan, Utah, from 1987, and president and CEO of its successor ElectroStar, Inc. from 1994.
the PCB (printed circuit board), plastic-injection molding and; the SCB. Using the SCB technology it is possible to structure and laminate the most widely differing material combinations in a reel-to-reel production process. [2] As the layers are structured separately, improved design concepts are able to be implemented.
PCB Bank (previously known as Pacific City Bank) is an American community bank that focuses on the Korean-American community based in California and offers commercial banking services. It has branches in 8 states and is the third largest Korean American Bank after Bank of Hope and Hanmi Bank .
