Low-temperature solder paste makes it easier to reflow-solder and re-work surface mount circuit boards. MG Chemicals offers a Bismuth-based paste that works great from larger passive components to fine pitched packages, like QFN. In this video, learn what solder paste is, what it means for a paste to be “low temperature,” and some things to watch out for when using it. This episode was sponsored by MG Chemicals.

Compare the ideal and measured cut-off frequency for a filter with a handheld LCR meter. Unlike a DMM, these meters apply an AC signal (from 100 Hz to 100 kHz) to determine the reactive component of an inductor, capacitor, or resistor. A simple example here is a low-pass filter. See how the ideal and measured cut-off frequency varies. And THEN, see how it compares between a PCB and a Breadboard. This episode was sponsored by…
