What are the steps involved in wave soldering explain them briefly?
The wave soldering process is composed of four steps: flux spraying, preheating, wave soldering, and cooling. Flux Spraying. Cleanliness of metal surfaces is the basic element ensuring soldering performance, depending on functions of solder flux. Solder flux plays a crucial role in smooth implementation of soldering.
What is the difference between wave and reflow soldering?
Wave soldering and reflow soldering are two soldering techniques that are totally different from each other. In wave soldering, the components are soldered, with the help of wave crest, which is formed by a melted solder. Reflow soldering is soldering the components, with the help of reflow, which is formed by hot air.
What is the principle of wave soldering?
Wave soldering is based on the principle of convection heat transfer to the welding area heating . The molten solder wave acts as a source of heat. On the one hand, it flows to wash out the pin welding area, on the other hand, it acts as a heat conduction. The pin welding area is heated under this effect.
What are the wave soldering defects?
Cavities
What is selective soldering process?
Selective soldering is one of the processes used in the construction of various electronic assemblies, usually circuit boards. Typically, the process involves the soldering of specific electronic components onto a printed circuit board while leaving other areas of the board unaffected.
What is wave process?
Wave processes. Introduction. The extent to which the shape of a beach or coast is altered depends largely on the action of waves upon it. Waves can be gentle and infrequent or larger, more frequent and more powerful. The formation of waves and their size and shape is a result of the exchange of energy from wind blowing over the sea.
