IEC 60068-2-27 Shock Testing for Packaged Devices
The IEC 60068-2-27 standard is a critical protocol that engineers and quality managers must adhere to when ensuring the robustness of packaged devices used in semiconductor and microchip testing. This test evaluates the impact resistance of packaged electronic components, which are integral to many industries including automotive, aerospace, medical electronics, and consumer electronics. The primary goal is to determine how well these devices can withstand mechanical shocks without compromising functionality or integrity.
Shocks occur due to a variety of factors such as transportation, handling, installation, and operational environments. These stresses can lead to internal damage within the packaged device, affecting its performance over time. By conducting IEC 60068-2-27 shock tests, manufacturers ensure that their products meet the stringent requirements set by international standards.
The test involves subjecting a specimen to controlled mechanical shocks using either drop testers or vibration tables. The specimen is placed in a position that simulates its real-world orientation and then subjected to a series of shock pulses designed to mimic typical environmental conditions. After each pulse, the device’s electrical characteristics are measured to assess any changes caused by the impact.
The selection of appropriate test parameters depends on several factors including the size and shape of the packaged device, expected operating environment, and desired accuracy levels for detecting damage. Specimen preparation involves cleaning and positioning the device correctly within the testing apparatus according to specified guidelines outlined in IEC 60068-2-27.
Once prepared, the specimen undergoes multiple cycles of shock pulses at varying amplitudes and frequencies depending on the type of packaging material employed. Vibration tables generate sinusoidal waves while drop testers produce free-fall impacts upon contact with a hard surface. Both methods aim to replicate real-world conditions experienced during shipment or installation processes.
Post-test analysis focuses on evaluating changes in electrical parameters like resistance, capacitance, and inductance compared to baseline readings taken before testing began. Any significant deviations may indicate internal damage resulting from the applied shocks. Engineers then use this information to refine design practices aimed at improving shock tolerance without sacrificing performance or reliability.
Compliance with IEC 60068-2-27 is essential for ensuring product quality and safety, especially when dealing with critical applications where even minor flaws could lead to catastrophic failures. Additionally, it helps maintain consistent standards across different manufacturers and regions worldwide.
