PCB-Investigator is a software tool used for the analysis, visualization, and optimization of printed circuit boards (PCBs). It is used for tasks such as PCB design validation and quality assurance. It is developed by EasyLogix [1] owned by Schindler & Schill GmbH, a German company specializing in electronic design automation (EDA) software.
Worst-case analysis is the analysis of a device (or system) that assures that the device meets its performance specifications. These are typically accounting for tolerances that are due to initial component tolerance, temperature tolerance, age tolerance and environmental exposures (such as radiation for a space device).
Uncertainty and decision analysis: Hall applied generalised theories of probability to civil engineering and environmental systems, including random set theory, [60] the theory of imprecise probability [61] and info-gap theory. [62] He applied the theory of imprecise probabilities to analyse tipping points in the Earth System. [63]
OrCAD Systems Corporation was a software company that made OrCAD, a proprietary software tool suite used primarily for electronic design automation (EDA). The software is used mainly by electronic design engineers and electronic technicians to create electronic schematics, and perform mixed-signal simulation and electronic prints for manufacturing printed circuit boards (PCBs).
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 ...
The first LOC analysis system was a gas chromatograph, developed in 1979 by S.C. Terry at Stanford University. [ 2 ] [ 3 ] However, only at the end of the 1980s and beginning of the 1990s did the LOC research start to seriously grow as a few research groups in Europe developed micropumps, flowsensors and the concepts for integrated fluid ...
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.
A common form of in-circuit testing uses a bed-of-nails tester.This is a fixture that uses an array of spring-loaded pins known as "pogo pins". When a printed circuit board is aligned with and pressed down onto the bed-of-nails tester, the pins make electrical contact with locations on the circuit board, allowing them to be used as test points for in-circuit testing.
