The demand of standardized interface plug connectors increases steadily especially on the market particularly by the reduction and complexity of the terminals in the area of mobile phones, computer technology, digital photography, film readers, entertainment electronics and GPS.
Therefore the trend also continues by I/O connectors getting smaller and smaller: After USB the mini-USB came and after this Micro-USB now. The concept for the standard Micro-USB 2.0 was developed by HIROSE Electric Co.,Ltd. in Japan. Of all introduced concepts the development of HIROSE Electric Co.,Ltd. was selected by the MicroUSB committee to the new MicroUSB standard.
