Vapor Pressure and Boiling
The molecules leaving a liquid through evaporation create an upward pressure as they collide with air molecules. This upward push is called the vapor pressure. Different substances have different vapor pressures and therefore different boiling points. This is due to differing intermolecular forces between molecules. The vapor pressure of a ...

Reflow soldering Solder Paste
Do you know the three main flux types in solder paste? Each of them has different properties. They are: 💧Rosin flux: This type of flux can withstand high soldering temperatures and is non-corrosive. It is typically not water-soluble and requires solvent-based cleaning after reflow to remove leftover flux. 💧Water-soluble flux: This type of flux, made from organic acids and solvents, is highly active. After reflow, the flux must be thoroughly washed away using water to avoid any corrosion. 💧No-
