Rosin Flux Rosin, or “Type R” flux, is the most basic soldering flux that has actually been used for thousands of years. Rosin is naturally derived from pine tar rosin, which can be farmed from trees. When it’s used as a soldering flux, rosin is then dissolved as a solvent in iso...

Insect flux also contains both harmful and beneficial substances (Chaves-Ulloa et al., 2016; Popova et al., 2017), differing between ecosystems. Moreover, very little is known on how potential changes in the synthesis and transfer of essential biomolecules in freshwater food webs influence ...
Reynolds Number: The Reynolds number is the ratio between the density, viscosity, velocity, and typical dimension of a flow in a dimensionless expression. The Reynolds number is used to identify whether a flow is laminar or turbulent. Studies have shown that the regime ...
This measurement can cut two ways – it can measure how much power you’ve used (which a utilities bill does), or how much capacity there is in a battery. For instance, a Tesla Model S 100D has 100kWh of capacity, of which you’ll be able to use about 90, because fully depl...
as a space-filling metal. This method is used to fabricate small components and perform maintenance on a circuit board. Silver offers a free-running individuality, although it is not typically an ideal choice for space filling on its own. This is why different flux is usually used to create...
