Two of these wavelengths are also in the infrared and red colour range. That allows some of the re-emitted light to emerge from the paste to where it can be analysed by an external instrument called a spectrometer. By precisely measuring the difference between the two wavelengths, the temperat...

The difference between wave soldering and reflow soldering: 1. Reflow soldering is the formation of high temperature hot air to reflow and melt solder to solder components; Wave soldering is to form molten solder into a solder wave to solder components. 2. During reflow soldering, the PCB alrea...
A substance applied to a surface to be joined by welding, soldering, or brazing to facilitate the flowing of solder and prevent formation of oxides. Flow To cause to flow "One of the real keys to success is developing a system where you can flow traffic to yourselves" (Marc Klee). Flux...

during welding or dewelding. However, the disadvantage is that the method reduces the copper surface area that can be used for solder joint connections and reduces the space between adjacentpads. This limits the thickness of the trace lines between the pads and may affect the use ofthrough-...
heat is transmitted downward due to the temperature difference between the high-temperature liquid at the top and the unmelted powder at the bottom. At the same time, the molten solder on the upper layer needs to absorb more laser energy to raise or maintain the temperature, resulting in a ...

① Flux is mainly suitable for soldering scenarios at high temperatures, such as electronic high temperature spot soldering, plate gold soldering and so on. It is added to the solder to improve the welding performance, such as reducing the welding temperature, extend the welding time. As well ...
