Types of FPC Connectors

There are several types of FPC connectors, each designed for specific applications and configurations. The most common types include:

  • Zero Insertion Force (ZIF) Connectors: ZIF connectors are designed to allow easy insertion and removal of the FPC. They have a mechanism that eliminates the need for excessive force, reducing the risk of damage to both the connector and the circuit. These connectors are ideal for applications requiring frequent reconnects.
  • Non-Zero Insertion Force (NZIF) Connectors: Unlike ZIF connectors, NZIF connectors require some force for the FPC to be engaged fully. They are simpler in design and often used in applications where the connections are made less frequently, providing a more robust and durable connection.
  • Vertical and Horizontal Connectors: Depending on the orientation of the FPC relative to the mainboard, connectors can be classified as vertical or horizontal. Vertical connectors are typically mounted perpendicular to the board, while horizontal connectors lie flat against the board surface. The choice between the two depends on space constraints and design specifications.
  • Shielded vs. Unshielded Connectors: Shielded connectors provide an additional layer of protection against electromagnetic interference (EMI), making them suitable for sensitive applications. Unshielded connectors, on the other hand, are lighter and more compact, making them a good choice when EMI is less of a concern.

FPC Connector Specifications

When selecting FPC connector types, understanding the specifications is critical. Key specifications to consider include the number of contacts, pitch (the distance between adjacent contacts), and the thickness of the FPC. Precision in these dimensions ensures compatibility and functionality within your electronic system.

The current rating of the connector is also essential, as it indicates the maximum load the connector can handle without overheating or failing. Furthermore, the operating temperature range is crucial for ensuring that the connector remains functional under the expected environmental conditions.
