Welding wire, also known as solder wire, is one of the indispensable auxiliary materials in the soldering of electronic products. Appropriate Application Solder wire can reasonably enhance the working efficiency of solder wire That is to say, the use of welding wire is very crucial. Factors such as improper use or differences in processing techniques, which are external force factors, all contribute to the actual welding effect of the welding wire. Now, JJY Tin Factory will give you a bonus:

Solder wireCauses of fatigue failure of solder joints:

During the transportation and application of the product after installation, spot welding is a weak point in stability. It plays various roles such as thermodynamics, electrical equipment, and sleeve connection, and is widely subject to regular mechanical stress and stress relaxation stress, especially in aerospace, aviation, ocean navigation, and vehicle cutting products. At this point, if there is an unreasonable overall planning causing some problems;Excessive ground stress or poor melt diffusion of the welding material aluminum alloy during the electric welding operation(Cold welding, segregation)Fatigue failure is more likely to occur, thereby reducing the service life of the solder joint.

How to remove exhausted and ineffective solder wire spot welding:

1If the process conditions are poor,6337Solder wire is prone to melting during welding and is likely to cause uneven diffusion. It must be avoided during the production process Only when the solder wire undergoes shrinkage porosity or the alloy composition is not ideal during the solidification process can the original stability or application service life of spot welding be reasonably enhanced.

2For solder wire spot welding, which is very prone to in-situ stress in the circulation system, the in-situ stress reduction plan should be taken into account in the overall planning. For instance, when fixing the installation holes and filling the electronic components suspended in the air with an appropriate amount of glue, it is also necessary to take into account the compatibility of the thermal expansion coefficients of various materials.

To enhance the service life of solder wires and solder joints, the above factors should be taken into account. It is advisable to purchase solder wires from regular manufacturers.
