EUNOS, Singapore - June 2, 2020 - Board to board connectors basically used to provide signal connections between two printed circuit boards (PCBs). These versatile contacts can be mounted on a single footprint which helps to swap in a new size easily when a design change is needed. These connectors are used for high-speed trains and industrial controls, and in data center storage and switching systems as it provide reliable high-speed data transmission with greater clarity, with flame-retardant, available in polarized housings that protect connections in harsh environments. Moreover, pre-loaded spring fingers are used on the board to provide shielding for preventing EMI noise and static. These have vast applications from a PCB in mobile and wearable devices, patient monitoring technology to security systems.

For single board computers (SBCs), designers need to fit as much processing power, functionality, and I/O as possible onto that circuit board to make the system compact. However, the reality a single board design can not provide best solution to industrial, consumer, and medical applications therefore multiple pc boards are needed. This is where board-to-board (BTB) connectors become really important and used to connect varios boards.

Board-to-board connectors provides major advantages in design, production, and marketing in situations where

• 
  
  Form factor limit the overall size of a single, larger board approach, and a three-dimensional arrangement is required to take benefit of available package depth.
• It is unacceptable to place low-level, highly sensitive analog I/O near high-speed, noisy digital circuits.
• High voltages are present, and safe as well as regulatory standards mandate separation.
• Thermal concerns require placing hotter components in a different locationor place for improved thermal management.
• A given circuit subpart may be used across multiple versions of a product, such as a core processing board which is paired with basic multiline user display and pushbuttons, as well as with a more sophisticated graphic touchscreen for different models of an alarm or sensor system.
• 
  Production requires special components, such as power devices and heatsinks that call for a special manufacturing/assembly process or manual insertion, while the rest can use automated insertion and soldering.
• 
  The vendor expects to upgrade one function in a system, such as the processor and memory, but wants to leave the analog function unchanged for technical confidence and cost amortization.

Connectors and interconnects are critical elements of a complete design that need due consideration up front. When multiple pc boards are used, BTB connectors (https://www.phoenixcontact.com/online/portal/sg?1dmy&urile=wcm:path:/sgen/web/main/products/subcategory_pages/Board_to_board_connector_P-11-09/07085809-594a-4650-bb64-8251a70150d7) offer a convenient, reliable, high-performance technique for connection between two or more boards in varied arrangements.
