I-PEX has applied the same technology we used in the development of coaxial connectors, “signal integrity × ultra-miniaturization,” to our high-speed transmission to board-to-board (FPC) connectors. In addition to the advantages of general board-to-board (FPC) connectors, we offer connectors that are ideal for internal connections that require high-speed transmission for mobile devices.

3) Full EMI Shield

General connector without metal shell I-PEX connector with metal shell
Without shell With shell

Connectors from I-PEX have  a structure that encloses the signal contacts/soldered parts of the plug/receptacle by providing shells on both the plug/receptacle. These connectors have excellent grounding characteristics  due to the structure in which the plug shell/receptacle shell connect with each other at multiple points when the connector is mated. Grounding takes place on  the board at multiple points, and the structure in which all signal contacts of the plug/receptacle are enclosed by a shield giving the connector  excellent i360-degree EMI shielding performance.
Interference with other high-frequency signals can be suppressed, allowing designers to place connectors near the antenna.

4) Install an Independent Power Terminal

We have connectors that achieve ultra-miniaturization while ensuring the power supply required for each application of mobile devices.

4-1) Connectors that can use hold-down as a power supply contact

NOVASTACK F3-1Because the hold-down feature of the  board-to-board connector is metal, it can be used as a power supply contact, as well as adding additional robustness to the connector.  The guide shape of the connector makes for smooth insertion and mating. Since the signal contacts do not have to be used for power supply, reducing the number of pin counts is effective in saving space.

4-2) Connector with Dedicated Power Terminal

NOVASTACK F3-2The dedicated power supply is 3.5 times wider than the signal contact and uses a Corson alloy that excels in electrical conductivity and heat conduction. (Signal terminal width: 0.12 mm, power supply dedicated contact width: 0.42 mm)

4-3) Connector for Power Supply

Input current Power contact : 6.0 A / pin  
Signal contact : 1.0 A / pin

Power contacts 6.0A x 4 pins and signal contacts 4 pins are equipped, and the hold-down and metal guide ensure mating easability and robustness.
