A desoldering pump, colloquially known as a solder sucker, is a manually-operated device which is used to remove solder from a printed circuit board. There are two types: the plunger style and bulb style. [1] (An electrically-operated pump for this purpose would usually be called a vacuum pump.)
Wiped joints were used for centuries to install water plumbing and similar joints can be seen in Roman plumbing. [3] As the wiping technique allowed a great deal of on-site flexibility for the style and dimensions of the work produced, this meant that plumbers needed few parts other than pipe, lead sheet and solder.
"Hard soldering" or "silver soldering" is used to join precious and semi-precious metals such as gold, silver, brass, and copper. The solder is usually described as easy, medium, or hard in reference to its melting temperature, not the strength of the joint. Extra-easy solder contains 56% silver and has a melting point of 618 °C (1,145 °F).
Solder (UK: / ˈ s ɒ l d ə, ˈ s ə ʊ l d ə /; [1] NA: / ˈ s ɒ d ər /) [2] is a fusible metal alloy used to create a permanent bond between metal workpieces. Solder is melted in order to wet the parts of the joint, where it adheres to and connects the pieces after cooling.
Both quantitative and qualitative tests for solderability exist. [6] The two most common testing methods are the 'dip and look' method and wetting balance analysis.In both of these tests, the soldered pieces undergo an accelerated aging process before being tested for solderability, to take into consideration the time a component was in storage prior to mounting to final assembly.
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. Hence a wide range of solder alloys exist, and only major ...
The most common leak detection method for pipeline operators is called the Supervisory Control And Data Acquisition (SCADA) system. This system uses a series of sensors to track data such as pressure, flow rates, temperature, and whether valves are open or closed.
Reflow soldering is a process in which a solder paste (a sticky mixture of powdered solder and flux) is used to temporarily attach anywhere from one to thousands of tiny electrical components to their contact pads, after which the entire assembly is subjected to controlled heat. The solder paste reflows in a molten state, creating permanent ...
