FFSD connectors are high performance, high reliability printed circuit board connectors that are used to connect flat flexible cables (FFC/FPC), to flexible printed circuits. FFC/FPC connectors can adapt to different shapes and sizes and are flexible. The connector was designed for electronic devices that require compact and high density connections. This device’s main goal is to effectively transmit electrical signals while minimising electromagnetic interferance (EMI) to ensure reliable and stable transmission.

A FFSD PCB Connector is made up of two parts.

The connector body: Usually made from plastic or another insulating material, with a locking system to secure the cable in place.

Metal contacts: These are used to contact the metal conductor wiring on the FFC/FPC in order to transmit signal or power.

What Is a Connector PCB?

A PCB connector connects and secures a printed circuit (PCB). The pin-press-in design has a superior clamping force for FPC cables. It is primarily used for board-toboard connections in order to provide a reliable and precise electrical connection. Plug-and-play (easy to connect, replace) and solder (stable, but difficult to replace) are the three most common types of connections.

What Is an FFSD PCB Connector?

FFSD connectors have specific housings and contact systems. They also feature unique locking mechanisms and compact housings. To ensure connection stability, reliability and adapt to specific application scenarios.

The FFSD connectors were designed for flexible connections to shielded cables. They are able to provide a high level of performance in environments that require high interference immunity, compact layouts and efficient connections for flexible flat cables and flexible printed circuits.

The majority of FFSD cables consist of flexible, flex-resistant material. These connectors have a double row of pins with a distance between them of 0.050 inches (1.27mm) to meet different signal transmission needs.

What’s the Structure of FFSD PCB Connector?

The connectors have a double row of pins with a distance between them of 0.050 inches (1.27mm) to meet different signal transmission needs. Pin counts can range from 3 to 25 and are suitable for a variety of circuit connections. Connector housings are often made of insulating plastics like PBT to protect internal components and facilitate alignment. They also incorporate features such as locking mechanisms for secure connection.

Cable mounting is a common mounting technique, in which the connector and cable can be joined by soldering, crimping or other methods, before the cable is attached on the PCB to transmit the signal. Some FFSD Connectors support surface mount technology, where the connector can be soldered directly on the surface of the board. This allows for different circuit layouts or design requirements.

What Are the Common PCB Connectors?

The most common PCB connectors are: Connectors with a male socket and a female pin, and a flexible metal plating. These are used to connect circuit boards and components.

USB connectors of Type A, B, and C are used to link circuit boards with components. These connectors transmit data and power using internal metal tabs. These connectors can also be used to charge electronic devices or transfer data.

HDMI connectors have shielding, multiple pins and are capable of transmitting audio and video in high definition.

SATA Connectors are used for serial data transfers. Both the data and power interfaces are present. This component is necessary to connect optical drives and hard disks with motherboards.

D-Sub Connector is also known as VGA Connector. It has multiple pins that transmit analog video signals. This connector is still used in older equipment and low-resolution environments to connect monitors and computers.

RJ45 Connector is equipped with 8 metal contacts on the inside for Ethernet connection. This is an essential part for wired network communication, such as the computer NIC and router LAN interface.

How Do you Choose a Plug in Connector?

When selecting PCB connectors, there are a few key things to keep in mind:

Understand the technical requirements for the application. This includes pin spacing, the soldering technique, the rated voltage and current, the number of plugs/unplugs, the temperature range, the board spacing, the connector geometry, the solder hole diameters on the tabs.

Contact resistance, insulation resistance and current limiting are all electrical properties of connectors.

Check the dimensions of the mounting space and the connector. Pay attention to the pins during the SMT procedure.

Packaging is important for automated assembly. The two most common packaging types are strip boxes and tape-and-reel packaging. The first is better for high-volume production. Tips on selecting PCB connectors: Female and Pin headers are common, cheap and ideal for large devices. It is also convenient and inexpensive.

Tips for Selecting Different Types of PCB Connectors:

Pin and Female headers is common and cheap, and suitable for large devices. The advantage is that it is convenient and cheap. However, the disadvantage is its large size.

High-end Board-to-Board Connectors are small and have many pins. They are suitable for compact products. The disadvantage is the high price and inability to plug-in/unplug frequently.

The thickened board to board connector is perfect for development and test boards. The connector is easy to connect and measure, but its downside is the large volume.

FPC connectors connect mother boards and daughter boards. The connectors are small, flexible and expensive. The FFSD PCB Connector’s Operating Principle The FFSD connector can be explained as follows: The FFC/FPC cable is inserted into the connector slot, and the conductive conductors on the cable are connected to the contacts of the connector. Many FFSD connectors feature a locking mechanism that prevents cables from coming out of the connector or falling out. After inserting and locking the FFC/FPC cable, the electrical signal is transmitted to the PCB through the connector contacts. The connector acts as a transmission bridge.

How Does the FFSD Connector Work?

FFSD connectors are based primarily on the manufacture and design of printed circuit boards, which are composed of printed components and circuits or a combination thereof. They are also pre-engineered to include insulating materials for the purpose of realizing the electrical connection between the electronic components.

The PCB connectors’ exact working mechanism is:

Metal wires and wires are used on the PCB to connect electronic components. The circuit’s electrical requirements are met by arranging and designing parameters such as wire path, width, and spacing.

PCBs anchor electronic components and provide mechanical support. They can be secured by soldering or insertion, and they ensure relative position and stability.

Wires and circuits on a PCB transmit signals to electronic devices. Factors such as noise rejection and interconnect lengths are taken into consideration to ensure stable transmission of signal and to reduce interference.

PCB connectors do not have to be traditional terminal blocks or pin connectors. These connectors are available in different forms such as BGA and SMT .

These connectors improve miniaturization, reliability, and integration in electronic products. PCB connectors have been widely used as carriers to connect, support, and manage electronic components in various electronic devices.

What Is the Advantage of FFSD PCB Connectors?

The main advantages of FFSD pcb connectors are:

Firstly the cable is adaptable and flexible. FFC/FPC Connectors can be bent and moved in a limited space when connected to FFC/FPC cables. The connectors can be adapted to fit different shapes and sizes of circuit boards.

The cable is also excellent at reducing electromagnetic interference in high-frequency environments, thanks to the shielding layer that’s applied on the surface. The cable is stable and reliable in its signal transmission, allowing the equipment to operate normally in complex electromagnetic environments.

The connector’s locking mechanism is also highly reliable. It can prevent the cable from falling out of place due to vibrations or shocks. It improves the durability and reliability of the electronic system by ensuring a stable connection.

The connector has good electrical performance. It is also highly customizable. The FFSD connectors are designed to meet specific requirements for applications, including cable length, width and bending angles, as well as the number of pins.
