A mechanical fastening system having an engaging component and a receiving component. The semiconductor die and the conductive column are embedded in the molding compound. A biasing member maintains the valve plunger against the valve seat. At another end, the switch includes an elongated portion provided horizontally with a blind hole provided in the center. The system and apparatus can be used in a method for cyclically applying and reducing a load on a test specimen to thereby subject the test specimen to tensile testing and can also comprise a mechanism for decoupling at least a portion of the load from the test specimen when the load is reduced. Masking members having holes bored in a desired electrode shape are attached to at least one side of an electrolyte membrane for a fuel cell before an electrode is applied to the electrolyte membrane, in a self-adhering fashion or through a slight adhesive.
