Solder joint is the major part of electronic devices to form an electrical connection and mechanical bond. Thus, study of electronics joint reliability is significant to determine the ability of the interconnection to maintain its functionality under subjected environments. Reliability of electronics joint is actually can be affected by its structure and materials used. As currently electronic devices is widely applied in automobiles application, the reliability of electronics interconnections under vibration loading is also an issue in this study as its leads to joint failure. Two 3D led with different conductive adhesive electronic joint structure that connected to a circuit model is developed by using Solidworks 2016, whereas ANSYS workbench 16.0 was used to simulate the models. Purpose of this research is to study the structural of conductive adhesive joint, strength and its reliability under vibration load. Two analyses were done, structural analysis and random vibration. Models was simulated in structural analysis and subjected to 1mm/min Y-axis displacement loading to analyze the adhesive joint structure and its strength.
