Understanding IEC 60749-8:2013

IEC 60749-8:2013 is a standard that pertains to the reliability of semiconductor devices. It provides guidelines for conducting vibration, shock, and seismic tests on these devices to evaluate their resistance to such environmental stresses. This article aims to provide a simplified explanation of the technical aspects of this standard, making it easier to understand for non-experts in the field.

Vibration Testing

Vibration testing, as per IEC 60749-8:2013, involves subjecting semiconductor devices to mechanical vibrations. The purpose is to simulate real-world conditions and assess if the product can withstand these vibrations without any damage or degradation in performance. The standard outlines specific test procedures, including the use of sinusoidal motions with different frequency ranges and amplitudes. Vibration testing helps manufacturers identify potential weaknesses in their devices and make necessary design improvements.

Shock Testing

Shock testing evaluates the ability of semiconductor devices to withstand sudden shocks or impacts. As outlined by IEC 60749-8:2013, devices are subjected to controlled mechanical shocks in different directions and magnitudes. This testing simulates scenarios where devices may be dropped accidentally or exposed to abrupt movements during transportation or usage. The standard defines parameters for acceleration, duration, and repetition of shocks to ensure accurate and comparable results from different test setups.

Seismic Testing

Seismic testing focuses on assessing semiconductor devices' resilience to earthquakes or other ground-motion disturbances. The standard provides guidelines for subjecting devices to horizontal and vertical vibrations that simulate various intensities of seismic activity. These tests help manufacturers ensure the structural integrity of their devices and their ability to continue functioning under earthquake conditions. By complying with the procedures outlined in IEC 60749-8:2013, manufacturers can design more reliable devices for areas prone to seismic activity.
