Introduction to Automated Test Fixtures

May 02, 2022 | Circuit Check

Testing of electronic assemblies involves three elements: the device under test, test equipment, and fixturing to make the connections between them. The challenge for a test engineer building a sophisticated test system is that instrumentation may need to measure thousands of test points through the mechanical interconnect....

The Effects of Temperature and Solute Diffusion on Volume Change in Sn-Bi Solder Alloys

Apr 26, 2022 | Qichao Hao, Xin F. Tan , Qinfen Gu, Keith Sweatman, Stuart D. Mcdonald, and Kazuhiro Nogita1

The different rates of thermal expansion of the many materials that make up an electronic assembly combined with temperature fluctuations are the driver of the thermal fatigue failure of solder joints. A characteristic of the Sn-Bi system, which provided the basis for many of the low process temperature solder alloys that the electronics industry is now adopting, is the very temperature-sensitive solubility of Bi and Sn in the other phase. In this study, in situ synchrotron powder x-ray diffraction was used to characterize the temperature dependence of the lattice parameters of the bSn and Bi phases in Sn-57wt%Bi and Sn-37wt%Bi. The effects of temperature and solute were separated by comparing with the data from pure bSn and pure Bi and verified using density functional theory calculations. Furthermore, the coefficients of thermal expansion of bSn and during heating were also derived to reveal the thermal expansion behavior.

SMT chip capacitor naming rules and methods

Apr 26, 2022 | Wendy

The naming of the chip capacitor: The parameters included in the name of the chip capacitor include the size of the chip capacitor, the material used for this chip capacitor, the required accuracy, the required voltage, the required capacity, the requirements of the terminal and packaging requirements. Generally, the parameters to be provided for ordering a chip capacitor should be the size, the required accuracy, the voltage requirement, the capacity value, and the required brand....
