Human-Metal Electrostatic Discharge in IEC, ANSI and MIL Standards

 

Janusz Baran, Częstochowa University of Technology, Częstochowa, Poland, Jan Sroka, Warsaw University of Technology, IETiSIP, Warsaw, Poland Abstract Simulation of the human-metal electrostatic discharge alters slightly from one to another standard. As a result, setups with different frequency bandwidth are required for the calibration of the ESD simulators. The rule of … [Read more...]

IEC Publishes Semiconductor Standard

 

IEC 60749-30:2005+A1:2011 establishes a standard procedure for determining the preconditioning of non-hermetic surface mount devices (SMDs) prior to reliability testing. The test method defines the preconditioning flow for non-hermetic solid-state SMDs representative of a typical industry multiple solder reflow operation. These SMDs should be subjected to the appropriate … [Read more...]

Standard on EMC Requirements for Power Supply Units

 

IEC 61204-3:2011 specifies electromagnetic compatibility (EMC) requirements for power supply units (PSUs) providing d.c. output(s) with or without auxiliary a.c. output(s), operating from a.c. or d.c. source voltages up to 600 V a.c. or 1 000 V d.c. The main changes with respect to the previous edition are listed below: - Update of the scope to align with IEC 61204-7. - Update … [Read more...]

IEC Releases RF Connectors Standard

 

IEC 61169-35:2011(E) provides information and rules for preparation of detail specification of 2,92 series RF coaxial connectors together with the pro-forma blank detail specification. It also prescribes mating face dimensions for high performance connectors - grade 1, dimensional detail of standard test connectors - Grade 0, gauging information and tests selected from IEC … [Read more...]

IEC Releases Semiconductor Standard

 

IEC 60749-40:2011 is intended to evaluate and compare drop performance of a surface mount semiconductor device for handheld electronic product applications in an accelerated test environment, where excessive flexure of a circuit board causes product failure. The purpose is to standardize test methodology to provide a reproducible assessment of the drop test performance of a … [Read more...]

EMC and Electrical Protection Standard

 

This technical report addresses electromagnetic compatibility and protection of telecommunications equipment that is typically used by telecommunications service providers. Topics covered included ESD, EMI (both emissions and susceptibility), Lightning, Power Induction (transient and steady state), Power Contact, Corrosion, and DC Power.Purchase the standard. … [Read more...]

IEC Releases Connectors Standard

 

IEC 60512-9-3:2011 defines a standard test method to assess the mechanical and electrical operational endurance, i.e. engaging and separating cycles, of a connector in an operating mode which includes a specified electrical load. This second edition cancels and replaces Test 9c of IEC 60512-5, issued in 1992, and constitutes a technical revision. The main technical changes with … [Read more...]

IEC Releases Microprocessor System Standard

 

ISO/IEC/IEEE 60559:2011(E) specifies formats and methods for floating-point arithmetic in computer systems - standard and extended functions with single, double, extended, and extendable precision - and recommends formats for data interchange. Exception conditions are defined and standard handling of these conditions is specified. It provides a method for computation with … [Read more...]

EU Begins Enforcement of Toy Safety Directive

 

The member states of the European Union will begin applying on July 20 the new measures of the Toy Safety Directive 2009/48/EC, regarding toys for children age 14 and under.The new Directive, which came into force in July 2009 and was implemented into national legislation in January 2011, brings in particular more references on chemicals by limiting the amounts of certain … [Read more...]
