The design kit brochure and the photographs do not help in providing usage information. How do they work? |

A wooden drumstick ,great for prodding and poking things in industrial panels. |

Each one in the kit is a plastic stick, several inches long. On the end is a chip capacitor with short stiff wires soldered to the terminations. The capacitor is held to the stick with heat-shrink tubing. One uses it by pushing it against the pads or terminations of a similar capacitor on a surface-mount board to increase the capacitance there. |

No solder, low mass, made from a single piece of high quality solid core conductor, all to get as low a thermal EMF as possible without spending daft money. --- End quote --- I would only advise regular cleaning before measurements in order to avoid the thermal EMF generated in the interface between copper and copper oxide. In a sense, one wants the maximum area of exposed copper to minimize resistance but on the other the more copper surface there is (without any protection like for instance gold plating) makes oxide more likely to appear. --- End quote --- Yep. Fortunately it's rarely humid here, so shouldn't oxidise much. I wonder if it would be worth getting one of those gold plating kits? I don't imagine making one out of gold wire would be cheap... |

for me, the Erem 15AGW Cutting tweezer is indispensible for all fine cutting and stripping work: https://www.newark.com/erem/15agw/smd-tweezer-bent-flat-4-5-carbon/dp/50B8499 |
