In the manufacturing process, the welding spot of PCB may lose efficacy because of the strain and stress impact. The reason for the occurrence of high-stress zones is the effect of the load brought by the manufacturing and assembly process. It is a giant challenge for the industry community to solve the problem of welding spots losing efficacy. In this paper, the manufacturing techniques and assembly process will be analyzed first. With the analysis result, the main impact of load would be checked. Then, with the confirmed allowable stress by calculation, the value of input stress, which may cause the welding spot to lose efficacy, would be obtained. Finally, the result of this study would be confirmed by the simulation result generated by the finite element analysis software.

“…Thus, a properly determined amount of Sn in the coating plays a vital role in influencing the tribological, mechanical, and chemical properties of the deposited layer [ 37 , 38 ]. Cu increases the thermal conductivity of the coating [ 26 , 39 , 40 , 41 ]. This property reduces the possibility of overheating among the contacting parts and maintains the temperature balance.…”

This article presents the research results of depositing anti-friction coatings (Babbitt) using three different casting methods: static casting, flame soldering, and clad welding. Babbitt alloy coatings deposited with different casting methods are discussed and explained in terms of changes in the coating properties, such as the microstructure, hardness, strength, and chemical composition. The results showed significant differences in the aforementioned properties, depending on the chosen coating deposition method. The results of the tests confirmed the importance of using shielding gas during deposition to ensure the chemical composition of the coating. The analysis revealed that decreases in the amounts of antimony and copper in the Babbitt coating compared with the initial concentrations were influenced by selective evaporation, oxidation, and the coating process parameters associated with different coating methods. To maintain the desired balance of mechanical properties in Babbitt coatings, it is important to control the antimony and copper contents. Clad welding deposition using a non-consumable tungsten electrode and argon shielding gas achieved a chemically stable coating quite close to the initial chemical composition of the Babbitt alloy.
