The soldering below has metallurgically joined the components to the PCB. However, it looks ‘messy’ and suggests more practice soldering is required. The soldering iron has been held for too long against the track and the component and consequently too much solder has been used. It is possib...
Soldering is a joining process used to join different types of metals, usually made of tin and lead which is melted using a hot iron and cooled to create a bond.
Soldering is one of the key processes in the manufacture of electronic equipment. Soldering allows electronic components to be electrically and mechanically joined so that they provide good stable and reliable connections for the life of the product....
PCB Manual Soldering: Temperature typically ranges between 240°C and 280°C, with higher temperatures (up to 350-370°C) for larger components.
The liquid is dispensed by hand or in a spray or foam format during wave or select soldering. In the wave process, the liquid can flow to the top side of an assembly. When this happens, the temperature on the top side of the board may not be high enough to evaporate the solvent. A...
What is lead-free soldering? Why has lead-free solder become mainstream?In the 1990's, a problem was revealed that lead (Pb) contained in soldering materials (such as Sn-Pb) of waste electronic components was melted away by acid rain and contaminated groundwater. Since then, the study of...

In the development of soldering materials, tin-lead alloy has always been the best and cheapest welding material, and it can meet the requirements of welding quality and reliability. However, with the strengthening of human awareness of environmental pro
The solder connection must be a solid mechanical joint as well as an effective corona suppression device. If it fails at either of these requirements it is not acceptable ball soldering. Making a good ball solder joint requires experience with the materials, solder time, temperature and technique...
Unlike welding and brazing, soldering doesn't melt the base metals; instead, it relies on the solder to create the bond. Soldering is good for delicate components and materials that can't handle the high temperatures needed for welding and brazing. Soldered joints are often flexible and provide...
