How to relieve solder wire solder joint fatigue

How to relieve solder wire solder joint fatigue

Jan 13, 2023

01-132023

To sum up, in view of the fatigue failure of solder wire solder joints, we require that the solder joints of solder wire must be very bright and not black in actual operation and application. The fatigue failure of solder wire solder joints mainly includes thermal fatigue and mechanical fatigue, of which thermal fatigue is the dominant cause.

Solder wire is one of the indispensable auxiliary materials in the welding of electronic products. That is to say, the use of solder wire is very critical, such as improper operation or process differences and other external factors. Both will lead to the welding effect of solder wire. Let's mainly understand the little knowledge about fatigue failure of solder wire solder joints:

Solder wire refers to the composition of tin alloy and flux. Lead solder alloy is divided into tin-lead + lead flux. Environmentally friendly solder is composed of tin-copper alloy + lead-free flux. Solder Wire is mainly used to fill, repair, and connect the main welding materials between two components, so what materials can solder wire weld, let's talk about it:

Solder is an important raw material for connecting electronic components when soldering lines, including tin wire, tin ball, tin bar, etc. Applied to all kinds of electronic soldering, suitable for manual soldering, wave soldering, reflow soldering and other processes. The wire solder used in standard soldering operations is called rosin cored solder wire or wire. Flux is added to the solder. This flux is composed of rosin and a small amount of activator.

Solder wire is an indispensable electronic auxiliary material in the post-soldering process, and PCB refers to the printed circuit board, which is the provider of electrical connections for electronic components. The printed circuit board is often represented by "PCB" instead of Call it a "PCB board".

One of the essential solder raw materials in the SMT production process is solder paste. The solder paste is divided into lead-free environmental protection solder paste and leaded solder paste according to environmental protection standards. Among them, lead-free solder paste is divided into low-temperature solder paste according to the melting point of the solder paste. So how to choose the solder paste suitable for patch in actual production?

Tin wire is a kind of solder material, which is mostly used for manual soldering products. At present, most tin wires contain flux such as rosin. Using tin wire can reduce the process and improve the efficiency of soldering operations. Leaded tin wires and lead-free tin wires can be distinguished from the following aspects:
1. Judging from the glossy color of tin appearance: the surface of lead solder looks bright white; lead-free solder is light yellow.
