Smartphones and other wireless mobile devices are like an 800-pound gorilla in the consumer electronics industry. Today, the mobile device market accounts for nearly 36% of the telecommunications market, and its sales continue to grow at a rapid rate. Since July 2010, mobile device users have exceeded the 5 billion mark, and the global market penetration rate is about 73%. From a statistical point of view, the number of people with mobile phones in the world today exceeds the number of people who have access to electricity.
When consumers buy smart phones, tablets, and other smart mobile devices, they often make decisions based on what they can use. In the case of Apple products, there are now more than 250,000 available applications (easy-to-use applications), and about 300 new applications are added every day, and more than 50,000 software developers actively develop software for this popular platform. While other popular smartphone operating systems may currently have few applications, these operating systems are also experiencing rapid growth as the number of 3G/4G networked devices grows.
Wireless users require wireless devices for greater convenience and versatility. In addition, they want devices that are portable and easy to read, so they can access information and entertainment at any time, anytime. Whether it's sending vacation photos from your mobile phone to Weibo, looking for restaurants and map directions on the road, watching a favorite HDTV series video, or taking a quick glance at a football game during a meeting, they demand that the smart mobile device in hand be instantly implemented. .
Clearly, we see that the convergence of content and demand has changed the way consumers interact with their computers and mobile devices; convergence is also affecting the performance of versatility and the need to quickly access information and entertainment content. The new smartphone will feature a next-generation ultra-fast memory card connector that allows users to download apps or videos from high-speed wireless networks and save, store, or download video content from the Internet to mobile devices, as well as from their Mobile devices are uploaded to their home network.
Connector supplier challenge
So how do these convergence trends affect suppliers of embedded connector systems in products such as smartphones, handhelds and tablets? As processors become more powerful and the content and transactions that need to be processed are almost endless, connector vendors are under pressure to provide small and micro-miniature connector products for mobile device manufacturers and their design engineers. Greater capacity, faster data speeds, and signal integrity and reliability.
These requirements have spurred leading connector manufacturers to develop a wide range of different types of microminiature connectors, offering extremely compact size, low cost, high performance and flexibility, making them ideal for wireless handheld devices. Below you'll find some of today's available microminiature connector solutions, developed specifically for handling typical 40-way signal applications in smartphones and other compact wireless devices.

Miniature Coax-to-Board Connector Solutions
The need for multi-pin micro-coaxial wire-to-board connection systems is enormous because of the large amount of data that must be processed in tightly packed mobile devices.
Flexible Printed Circuit (FPC) has been used to connect a high-resolution LCD display to the main keyboard of a flip phone. However, these flexible solutions also have problems such as electromagnetic interference (EMI) and mechanical durability and flexibility. For example, the latest screen-changing phones require the LCD screen to be rotated at approximately 360 degrees in any direction, but the flexible line cannot handle this excessive rotation. In order to absorb stray EMI, grounding and shielding should be provided between the signal traces. However, the extra ground traces take up more space and hinder the miniaturization of handheld devices. The use of shielded flexible circuit boards reduces the flexibility and durability of devices that use flip or swivel hinges.
A miniature coaxial cable system with fully shielded, 0.40mm or 0.30mm pitch multi-pin, ultra-thin 42AWG or 44AWG coaxial wire provides a solution to all of these problems. While this solution is more expensive than a flexible solution, miniature coaxial cables are a more appropriate choice when designers demand better performance and additional functionality. The miniature coaxial wire-to-board connector system is ideal for rotary hinges/necks, digital video cameras, notebook computers, smart phones and IP webcams for mobile phones.
Micro-pitch flexible printed circuit board connector solution
Micro-pitch flexible printed circuit connectors (FPCs) offer many features that are important for use in tight-package applications, and their compact size provides the space savings required, for example, between PCB boards and LCD modules. Space.
In addition, the FPC connector also provides a zero insertion force actuator that can be used repeatedly with minimal wear. These miniature connectors come in a variety of fine pitch options, including slide and flip actuators, all pre-assembled to include connection protection between the FPC and the connector terminals.
Some connectors feature a two-contact design, so those that require a top contact type for one board and a bottom contact type for the other board do not need to order two different types of FPC connectors. Some products offer a unique FPC lock that helps provide positioning and cable retention while keeping the cable in place for easy insertion.
In general, FPC connectors offer flexibility in both board design and tight package, eliminating the need for mating connectors such as wire-to-board or board-to-board connectors by providing a one-piece solution that reduces The cost.
Mini Board-to-Board Connector Solutions
As you said in the real estate industry, the three most important factors are location, location or location. In the PCB "real estate" market, size is really important for micro-mini board-to-board connectors. Due to the reduced size and increased functionality of consumer entertainment devices, smart phones and other handheld devices, there are four most important dimensions when designing a PCB that connects two small PCBs:
• Low side height, stack height (H) less than 1.00mm
• Shallow depth, the connector has a narrow width of less than 3.00mm
• Small footprint, connector end-to-end dimensions (depending on circuit size)
• Small pitch, center-to-center contact point spacing of 0.40mm or less
Figure 2 These miniature surface mount connectors are suitable for tightly packed applications such as cell phones, digital cameras or portable audio devices.
Where does the development trend point?
As smartphones and other consumer devices continue to shrink in size, design engineers are increasingly under pressure to maximize PCB space and power efficiency. The new features of these devices increase the number of signals required and improve the quality of signal performance. Leading connector manufacturers must be creative and provide innovative technologies and products to enhance electrical and mechanical performance in smaller PCB footprints.
Today, 3G/4G smartphones in the OEM market require smaller connectors than before, and this trend will continue. Design engineers now have connectors available, with low side height (H = 0.70mm), very shallow depth (W = 2.60mm) and very fine 0.40mm pitch; and also with a unique design Mounting pins under the plastic seat for maximum package area and design flexibility. For example, a 40-way ultra-low side height (H = 0.70 mm) micro-board-to-board connector occupies less than 28 mm of PCB area.
To address other signal integrity issues or interference caused by PCB components being too "noisy", some micro-board-to-board connectors provide an external metal shield to improve performance. Design engineers who consider the electronics to operate in high-vibration applications can utilize micro-pitch micro-board-to-board connectors to achieve very high retention or to provide a permanent mating solution that can be tested by drop.
The cost of PCB boards is approximately 0.015 cents per millimeter. These miniature connectors provide designers with a wide range of connections, including LCD displays, keyboards, membrane switches, A/V or RF boards, and modems. , or a GPS card connected to the main PCB. Moreover, as the market continues to grow, the world's leading connector suppliers will continue to break through the limits of technology and provide the best solution at a competitive price.
