Since its official release on December 9, 2002, HDMI has been available for 15 years. As a new digital multimedia transmission interface, HDMI has higher bandwidth, stronger anti-interference ability, support for audio and video The advantages of synchronous transmission and the like have successfully replaced the traditional VGA and DVI interfaces. Recently, the HDMI organization has developed the HDMI 2.1 standard, which provides up to 48Gbps of bandwidth, allows you to watch 4K 120Hz video content, and each pixel has a color depth of up to 12bit, for Intel, NVIDA and AMD, this It will be good news. What's even more exciting is that HDMI 2.1 is backwards compatible with versions under 2.1, which means that you don't have to change the HDMI cable to use it, but it's worth noting that if you want to experience high 48 Gbps, you have to use Cables that support the HDMI 2.1 standard are available. In terms of sound effects, HDMI 2.1 supports the new eARC technology and can return Object-based sound effects such as Dolby Atmos over existing ARC (Audio Return Channel). Interfaces, HDMI 2.1 will continue to correspond to the original HDMI A, C and D plug design. And support for the new Dynamic HDR technology, compared to the current "static" HDR, "dynamic" HDR can further enhance the contrast with the light and dark levels of performance.
Antenk manufactures a wide range of application specific board stacking connectors which were designed and built to specific customer requirements. Our experienced staff has developed custom products in a variety of contact styles, pitches and stacking heights. Our designs range from new concepts to duplicating existing market products identically or with improvements. Many desigsn are produced using automated manufacturing processes to increase reliability and provide significant cost savings
Board to Board Connector
Board-to-board (BTB) connectors as the name indicates is used for connecting circuits board together. This kind of connectors are suitable for stacking circuits boards one over another. Flat flexible cables can be avoided using these kinds of connectors; moreover it makes the entire unit more compact. The commonly used BTB connectors are SMT connectors and Berg Strip. We will discuss about them in detail in the following section.
SMT CONNECTOR
Board-to-board (BTB) connectors are used to connect printed circuit boards (PCB), electronic components that contain a conductive pattern printed on the surface of the insulating base in an accurate and repeatable manner. Each terminal on a BTB connector is connected to a PCB. A BTB connector includes housing and a specific number of terminals. The terminal is made from a conductive material (mostly copper alloy), and plated to improve conductivity and antirust. Terminals transmit the current/signal between PCBs connected by BTB; the housing is made of insulating material (mostly plastic).
The way mount Board to Board Connectors on a PCB
board to board connectors are available in the following pitches: 04mm/0.5mm/0.8mm/1.0mm/1.27mm/2.54mm/3.96mm/4.0mm

Surface Mount Technology (SMT) connector is a commonly found board-to-board connector in advanced circuit boards. As the name indicates this connector is available only in surface mount model. It is carefully mounted on to the solder pads on the surface of the PCB.
SMT connectors are ideal candidate for miniaturization due to their small area of occupancy and stacking height. They are suitable for double layered or multilayered PCBs. They are designed for high performance and reliability.
They commonly found in advanced circuit boards in networking equipment, telephones, mobile phones, computers and other consumer electronics.
The basic types of Board to Board Connector
Broadly speaking, board to board connectors are manufactured in the following types:
Pin Header
Elevated Pin Header
Socket
Elevated Socket
Shrouded Header
Box Header
board to board connectors are available in through hole (TH) and Surface Mount (SMT) variants.
Locating pegs (also referred to as locating posts, alignment pins or board locks) are used to assist alignment of connectors to the PCB. Locating pegs are particularly useful when using surface mount components.
For experienced hardware designers choosing board to board connectors is second nature, for the uninitiated it can be daunting. We offer design support and will help guide you through the options available. If you need help with your board to board connector design, contact antenk. Where required antenk also offer non standard pitches.
