2. Solder paste - Wikipedia

   en.wikipedia.org/wiki/Solder_paste

   The amount of time solder paste can stay on a stencil without affecting its printing properties. The paste manufacturer provides this value. Tack Tack is the property of a solder paste to hold a component after the component had been placed by the placement machine. Hence, tack life is the critical property of solder pastes.

3. Tin-silver-copper - Wikipedia

   en.wikipedia.org/wiki/Tin-silver-copper

   Tin-silver-copper (Sn-Ag-Cu, also known as SAC), is a lead-free alloy commonly used for electronic solder. It is the main choice for lead-free surface-mount technology (SMT) assembly in the industry, [ 1 ] as it is near eutectic , with adequate thermal fatigue properties, strength, and wettability. [ 2 ]

4. Solder alloys - Wikipedia

   en.wikipedia.org/wiki/Solder_alloys

   Soldering copper pipes using a propane torch and a lead-free solder Solder is a metallic material that is used to connect metal workpieces. The choice of specific solder alloys depends on their melting point , chemical reactivity, mechanical properties, toxicity, and other properties.

5. Soldering - Wikipedia

   en.wikipedia.org/wiki/Soldering

   Reflow soldering is a process in which a solder paste (a mixture of prealloyed solder powder and a flux-vehicle that has a peanut butter-like consistency [8]) is used to stick the components to their attachment pads, after which the assembly is heated by an infrared lamp, a hot air pencil, or, more commonly, by passing it through a carefully ...

6. Solder - Wikipedia

   en.wikipedia.org/wiki/Solder

   Solder used in making electrical connections also needs to have favorable electrical characteristics. Soft solder typically has a melting point range of 90 to 450 °C (190 to 840 °F; 360 to 720 K), [3] and is commonly used in electronics, plumbing, and sheet metal work.

7. Solder ring fitting - Wikipedia

   en.wikipedia.org/wiki/Solder_ring_fitting

   To obtain functional joints, the inside of the fitting and the outside of the copper pipe are cleaned using steel wool or cleaning tape, flux paste is applied, the pipe is inserted into the fitting and heat is applied from a portable butane torch or propane torch until a ring of solder shows at the edges of the fitting. To obtain a durable ...
