Soldering (see RoHS), has led to a change in formulation of both solders and fluxes. Water-soluble non-rosin-based fluxes have been increasingly used since the 1980s so that soldered boards can be cleaned with water or water-based cleaners. This eliminates hazardous solvents from the production environment, and from factory effluents. Those regulations have also reduced the use of lead based solders, and caused the melting temperatures of solders in use to increase by up to . "Hot-bar reflow" is a selective soldering process where two pre-fluxed, solder coated parts are heated with heating element (called a thermode) to a sufficient temperature to
Electrical connector other connectors such as Banana connectors. A connector that locks a metal spade to a terminal by screwing them together. Crimp connectors can be used for fast and friction-type connections in DC applications where connections are broken repeatedly. Alligator connectors are often used as temporary test leads. A screw terminal is a type of electrical connector where a wire is held by the tightening of a screw. Phone connectors can be used as connectors in microphone cables and for low-voltage, low-current applications. Pogo Pin Connectors or Spring Loaded Connectors is a connector type commonly used in consumer products. The Connector
