Soldering flux is (or at least, should be) one of the ubiquitous features of any electronics bench. It serves the purpose of excluding oxygen from a solder joint as it solidifies, and in most ...

and promote wetting of the surfaces by the solder metal. It is also important to use fluxes that meet the ASTM B 813 standard so that any flux residue left inside the system will flush out with water.

As the solvent volatizes, the viscosity of the flux remnant increases, making the residue less mobile or difficult to be excluded from the interior of the solder.返回搜狐，查看更多 ...
