Another joining process which is commonly used in industrial production and electrical engineerig is soldering. This process guarantees a stable, stainless, electrographic and thermoconductive joint between two metallic components. Soldering uses a metal alloy that melts easily as a filter material. This is applied additionally to join the parts and allows the joining of different materials.
Furthermore soldering can be conducted in vacuum or shielding gas. Then it ensures to meet stringent cleanliness requirements, e.g. for semiconductor assembly or special joints for high vacuum systems or electron tubes. The process is used for example in the production of photovoltaic modules or in general in the small-series production of electronic components.
