Mobile phones more and more micro-miniaturization, user groups are increasingly popular, the production of increasingly large number of mobile phone components, including connectors, including the increasingly stringent requirements. Current trends are as follows:

■ miniaturization of mobile phone size and weight significantly reduce the increased functionality, you need high-density mounting and interconnection. Clearly requires that its internal components (including connectors included) must be getting smaller, or to integrate them into a chip or circuit module. Micro-miniaturization is the only way.

■ With the development of miniaturization and mass production of high-speed automated assembly technology, surface mount, and to reduce the connection part of the occupied space, surface mount connectors to develop rapidly, and gradually replace the perforated plug connector. Production of surface mount connectors (SMC) leads (feet) spacing from 2.00mm, 1.27mm development to 0.8mm, 0.5mm, and even launched a 0.3mm flexible PCB connectors. Mounting height reduced from 10mm to 2mm, and even launched a 1.5mm board to board connector.

■ standardized and modular to adapt to the needs and convenience of the mobile phone mass production, space savings and ease of design, the phone circuits and components, including connectors including modular, rapidly and a strong need to form a unified international standards. Of course, this will affect all manufacturers with a different personality and characteristics, morphology, cell phone, but the problem is not difficult to resolve (see behind the introduction of the "Hamburg cell phone" design philosophy).

■ multi-function interface is easy to use for the user, but also simplify the design and manufacture of mobile phones, mobile phone number of the external interface as possible. This does not make users face a variety of interfaces at a loss. So they requested that the phone's external interface connector multi-functional, it can be low frequency contacts, high-frequency coaxial port and other interfaces with different characteristics compound in one to meet the connectivity requirements of different uses. Phone the bottom of an interface for connecting external devices such as charger, microphone, headset or hands-free bearing.

■ Operating the popularity of the simple user base, the use of mobile phones must be simple and clear, must be intuitive, the connector has the same requirements. Such as the SIM card is installed, install the battery, connect the charger must be easy to operate, a look will be. But also secure to prevent misuse and to prevent the inserted backwards or inserted in the wrong hole. However, these interfaces are more simple to the user, the connector design and manufacture of technical requirements for the higher and more complex.
