Our commenteers have all said good things about the open-source TS100 soldering iron pencil: things like “it solders well”. But we’ve all got soldering irons that solder well. What possible ...

From there, some general soldering tools like flux and solder wick, a stencil for your chip, BGA balls, and a $20 USB-C hotplate are instrumental for reballing chips – tools you ought to have.

Abstract: A transformer winding method which can realize an adjustable turns ratio is proposed. In this paper, the LLC resonant converter is taken as an example, where the full-bridge (FB) LLC ...

Capacitance in a transformer winding cannot be avoided. The voltage difference between turns, between winding layers, and between windings to core, create these parasitic elements. In general, part of ...

Many dielectric and mechanical failures in large power transformers are preceded by mechanical changes in the winding structure. These changes, or displacements in the winding structure, may be the ...

Abstract: The 1916 A. I. E. E. Rules require that the temperature rise of transformer windings be observed by the resistance method. Since the measurement of resistance usually requires considerable ...
