HMI is the abbreviation of human machine interface, which is also known as user interface. It is the medium of interaction and information exchange between the system and users. It can complete the work of information transformation between the internal form of machinery and the acceptable form of human beings. Wherever there's human-computer information exchange, there's HMI.

The use of an electroless nickel, immersion gold (ENIG) surface finish comes with the inherent potential risk of Black Pad failures that can cause fracture embrittlement at the interface between the solder and the metal pad. As yet, there is no conclusive agreed solution to effectively eliminate Black Pad failures. The case studies presented are intended to add to the understanding of the Black Pad failure mechanism and to identify both the plating and the subsequent assembly processes and conditions that can help to prevent the likelihood of Black Pad occurring.
