Introduction of board-to-board connectors

According to the current connector market to see the Board-To-Board Connectors are more and more widely used background and driving force from the wireless device market two major trends: the size will be smaller, the price will be lower. As seen in the wireless terminal market, smaller, lighter, cheaper, and is the trend in the development of the wireless device market.

The reduction in device size means that it saves space, reduces weight and leaves more excess for the rest of the system design. The decreasing size of devices requires higher integration and smaller size of all devices in the device, including RF coaxial connectors and their cable assemblies that are widely used in RF modules and interconnections between them.

The RRH (remote radio head), which is widely used in distributed base station systems, must be designed to be very compact and controlled in size in order to be easily, conveniently and reliably installed on top of towers and in dense urban environments, which requires the coaxial interconnection system carrying the RF signal transmission to be more compact and simple.

Traditional cumbersome cable assembly connections are being replaced by simple, compact, reliable "board-to-board" coaxial connector connections that can carry more than 100W of RF signal power at the same time.

Now more and more RF and structural design engineers are becoming more familiar with the board-to-board connectors, and more and more designs are using board-to-board connector connections, which makes designers more and more cost considerations, the market needs to design simpler, lower-cost board-to-board connector solutions.

Connector size continues to get smaller brings in the mechanical design challenges in two main areas: First, compared to large size connectors, small size connectors are more difficult to match the alignment. Second, the mechanical strength of the small size connector is low, such as improper use is more likely to damage. Generally large connectors can withstand the use of greater mechanical force in the fit without damage, but small connectors need to be more accurate in the fit.
