Strength and strain analysis for printed circuit boards

As electronic devices are getting smaller, thinner, and more functional, the density of printed circuit boards is increasing. As a result, key input components (such as integrated circuits and switches), connectors, etc. are mounted on an increasing number of single printed circuit boards. Parts such as key input components and connectors are subject to physical movement, such as pressing and connection to/disconnection from wires, and therefore apply a large load to printed circuit boards. Applying this load may cause damage or detachment of mounted components, so it is important to inspect the strength and strain of printed circuit boards beforehand using a strain gauge.
