2. Soldering station - Wikipedia

   en.wikipedia.org/wiki/Soldering_station

   A soldering station is a multipurpose power soldering device designed for electronic components soldering. This type of equipment is mostly used in electronics and electrical engineering . Soldering station consists of one or more soldering tools connected to the main unit, which includes the controls (temperature adjustment), means of ...

3. Contact pad - Wikipedia

   en.wikipedia.org/wiki/Contact_pad

   Pads are positioned on the edges of die, to facilitate connections without shorting. Contact pads exist to provide a larger surface area for connections to a microchip or PCB, allowing for the input and output of data and power. Possible methods of connecting contact pads to a system include soldering, wirebonding, or flip chip mounting.

4. Thermal relief - Wikipedia

   en.wikipedia.org/wiki/Thermal_relief

   Thermal pads can be seen in several locations on this printed circuit board (PCB), in particular, the bottom pad of the three vertical pads in the top left corner. A thermal relief pad, thermal pad or simply thermal, is a printed circuit board (PCB) pad connected to a copper pour using a thermal connection. It looks like a normal pad with ...

5. Solder paste - Wikipedia

   en.wikipedia.org/wiki/Solder_paste

   Solder paste is used in the manufacture of printed circuit boards to connect surface mount components to pads on the board. It is also possible to solder through-hole pin in paste components by printing solder paste in and over the holes. The sticky paste temporarily holds components in place; the board is then heated, melting the paste and ...

6. Wave soldering - Wikipedia

   en.wikipedia.org/wiki/Wave_soldering

   Wave soldering is a bulk soldering process used in printed circuit board manufacturing. The circuit board is passed over a pan of molten solder in which a pump produces an upwelling of solder that looks like a standing wave. As the circuit board makes contact with this wave, the components become soldered to the board.

7. Thermal expansion valve - Wikipedia

   en.wikipedia.org/wiki/Thermal_expansion_valve

   A thermal expansion valve or thermostatic expansion valve (often abbreviated as TEV, TXV, or TX valve) is a component in vapor-compression refrigeration and air conditioning systems that controls the amount of refrigerant released into the evaporator and is intended to regulate the superheat of the refrigerant that flows out of the evaporator ...
