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...]
