In PCBA processing, soldering methods mainly include reflow soldering, wave soldering and manual soldering. Each of these several welding methods has its own characteristics. Today, Sanjing will mainly introduce wave soldering and manual soldering.

 

Manual welding, as the name suggests, is manual welding. The biggest problem with this welding method is that the welding quality and efficiency are relatively low. As the density of the circuit board increases and the thickness of the circuit board decreases, the soldering heat capacity increases, and the soldering iron soldering can easily lead to insufficient soldering heat, resulting in virtual soldering or insufficient through-hole climbing height. If the soldering temperature is increased excessively or the soldering time is prolonged, it is easy to damage the circuit board and cause the pad to fall off.

 

However, due to the wide application of high-quality intelligent soldering irons, the quality of welding has been improved. However, there are still some factors that are difficult to control, such as the control of the amount of solder and the wetting angle of the solder joints, the control of soldering consistency, and the The requirement of tin hole through tin rate, etc. Especially when the component leads are gold-plated, the parts that need to be soldered must be removed and tinned before soldering, which is more troublesome.

 

 

When wave soldering, the welding parameters of each solder joint can be "tailored", and there is enough process adjustment time to adjust the welding conditions of each solder joint to the best, such as the amount of flux sprayed, the welding time and Welding wave height, etc., can greatly reduce the defect rate, and even weld through-hole components with zero defects.

 

The traditional manual soldering iron soldering requires butt-point soldering on the PCBA, while the wave soldering method first applies the flux, then preheats the circuit board, melts the flux, and then uses the soldering nozzle for soldering. Welding nozzles of different sizes can be used for batch welding in the form of drag welding. The welding efficiency is dozens of times higher than that of manual welding. It is usually suitable for mass production mode of assembly line.

 

Wave soldering uses a programmable and movable small tin cylinder and a variety of flexible soldering nozzles, so certain fixing screws and ribs on the B side of the PCB can be avoided by programming during soldering to avoid contact To high temperature solder and cause damage.

 

From the comparison of wave soldering and manual soldering above, wave soldering has the excellent characteristics of good soldering quality, high efficiency, strong flexibility, low defect rate, less pollution and various soldering components.
