Wave flow soldering is a method of soldering all the connections on a printed circuit board in a single step on a machine (instead of one at a time by hand).
A wave flow soldering machine has the following parts:
- a heated tank containing molten solder covered with a thin layer of flux
- one or more printed circuit board fixtures
- a mechanical wave generator
Printed circuit boards are populated with components (on automatic part placement machines and/or manually by human assemblers). The populated printed circuit boards are placed in the fixtures. As each fixture goes into the wave flow soldering machine the wave generator sends a wave of solder down the length of the heated tank. The top of this wave just touches the bottom of the printed circuit board, soldering all the connections. After the fixtures leave the wave flow soldering machine they are allowed to cool a while and the printed circuit boards are removed.
The soldered printed circuit boards are then washed to remove any flux residue left by the wave soldering machine, then sent to be tested to make sure they function as intended.
Wave flow soldering works best for "through hole mounted" components.

How do you avoid hand soldering?
Wave soldering is a process where components are held in place and the entire board is soldered at once.

Why the components not fell down in case of wave soldering?
During wave soldering, components are held in place by surface tension of the solder. As the printed circuit board moves over the wave of molten solder, the surface tension of the solder keeps the components in position until the solder solidifies, preventing them from falling off. Additionally, the design of the PCB and components ensures proper alignment and stability during the wave soldering process.
What does 'continued their career' in surfing mean?
It means they continued to flow in the wave of the ocean or sea
What is the purpose of borax in soldering?
Borax is used as a flux in soldering to clean the metal surfaces being joined and to prevent oxidation during the soldering process. It helps the solder flow more easily and create a strong bond between the metals.
What is free flow solder?
Free flow solder is a type of solder designed to enhance its fluidity during the melting process, allowing it to easily and uniformly fill joints and gaps in electronic assemblies. It typically contains a combination of metals, such as tin and lead or lead-free alternatives, and is used to improve the reliability and strength of solder connections. Its properties enable better wetting on surfaces, making it particularly useful in wave soldering and reflow soldering processes in electronics manufacturing.
What is the difference between continuous and pulsed wave laser?
Continuous I assume would mean a constant flow of light from the laser in the form of a wave train. Conversely, a pulse is only a single wave emitted by the laser.
What does depolarization of the heart mean?
It is a positive wave in the hearts muscle cells, the process of electrical discharge and the flow of electrical activity.
What does wave-sliding mean?
Wave-sliding is a term used in surfing to describe the technique of riding a wave in a smooth and controlled manner without making abrupt movements. The surfer effortlessly glides along the face of the wave using the momentum and energy of the wave to maintain speed and flow.
Why soldering iron melt the lead?
Soldering irons are designed to heat up the lead in solder to its melting point, allowing it to flow and create electrical connections. The high temperature of the soldering iron transfers heat to the lead in the solder, causing it to melt and bond with the materials being soldered.
What is cold flow?
It is a term used when soldering with a soldering iron. It means that the solder is not completely up to temperature to make a proper joint. A good solder joint is very silvery in colour and shines when it is done right.
What is constant if flow through a Prandtl-Meyer expansion wave?
The flow's Mach angle is constant through a Prandtl-Meyer expansion wave.
