Moisture sensitivity level (MSL) is a rating that shows a device's susceptibility to damage due to absorbed moisture when subjected to reflow soldering as defined in J-STD-020. It relates to the packaging and handling precautions for some semiconductors.
The standard has withdrawn in favor of international standards IEC 60603-2 and EN 60603-2. DIN 41612 connectors are used in Pancon , [ 1 ] STEbus , [ 2 ] Futurebus , VMEbus , Multibus II, NuBus , Acorn Archimedes expansion bus, [ 3 ] VXI Bus, [ 4 ] eurocard TRAM motherboards, [ 5 ] and Europe Card Bus , all of which typically use male DIN 41612 ...
The European Committee for Standardization (CEN) had issued numerous standards covering welding processes, which unified and replaced former national standards. Of the former national standards, those issued by BSI and DIN were widely used outside their countries of origin. After the Vienna Agreement with ISO, CEN has replaced most of them with ...
The symbolic representation of a V weld of chamfered plates in a technical drawing. The symbols and conventions used in welding documentation are specified in national and international standards such as ISO 2553 Welded, brazed and soldered joints -- Symbolic representation on drawings and ISO 4063 Welding and allied processes -- Nomenclature of processes and reference numbers.
