It relates to the packaging and handling precautions for some semiconductors. The MSL is an electronic standard for the time period in which a moisture sensitive device can be exposed to ambient room conditions (30 °C/85%RH at Level 1; 30 °C/60%RH at all other levels). Increasingly, semiconductors have been manufactured in smaller sizes.
IEC 60068 is an international standard for the environmental testing of electrotechnical products that is published by the International Electrotechnical Commission (IEC).. IEC 60068 is a collection of methods [1] for environmental testing of electronic equipment and products to assess their ability to perform under environmental conditions including extreme cold and dry heat.
IEC 60077 Railway applications – Electric equipment for rolling stock; IEC 60079 Explosive atmospheres; IEC 60081 Double-capped fluorescent lamps – Performance specifications; IEC 60083 Plugs and socket-outlets for domestic and similar general use standardized in member countries of IEC
Virtually all rugged computers share an underlying design philosophy of providing a controlled environment for the installed electronics. Rugged computers are engineered to operate in the face of multiple challenges including: Shock and vibration; Temperature and humidity; Corrosion and abrasion; Minimal size, weight, and power (SWaP)
The European Telecommunications Standards Institute (ETSI) is an independent, not-for-profit, standardization organization operating in the field of information and communications. [1] ETSI supports the development and testing of global technical standards for ICT-enabled systems, applications and services.
A hygrometer is an instrument which measures the humidity of air or some other gas: that is, how much of it is water vapor. [1] Humidity measurement instruments usually rely on measurements of some other quantities such as temperature, pressure, mass, and mechanical or electrical changes in a substance as moisture is absorbed.
An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum operating temperature to the maximum operating temperature (or peak operating ...
The typical sweet spot for IrDA communications is from 5 to 60 cm (2.0 to 23.6 in) away from a transceiver, in the center of the cone. IrDA data communications operate in half-duplex mode because while transmitting, a device's receiver is blinded by the light of its own transmitter, and thus full-duplex communication is not feasible. The two ...
