High-Density FC Series Mini-Rectangular Connectors - China Suppliers & Factory for Reliable PCB Interconnection
Features and Advantages
-
1The primary feature of this series is its 2x2mm mesh grid contact arrangement. This uniform grid pattern provides significant design flexibility and allows for efficient, high-density routing on the PCB.
-
2This layout offers the key advantage of maximizing the contact count in a minimal area, which is essential for modern, miniaturized electronics.
-
3The connectors are typically designed with a secure mating interface, such as a low-insertion-force (LIF) or zero-insertion-force (ZIF) mechanism with a positive locking system, to ensure reliable connection and resistance to vibration.
-
4This design delivers stable electrical performance and durability through repeated mating cycles. The construction often utilizes materials and plating (e.g., gold over nickel) that ensure excellent conductivity, corrosion resistance, and longevity.

Frequently Asked Questions
Q
What does the 2x2mm mesh grid contact arrangement mean for PCB design?
The 2x2mm mesh grid contact arrangement means that the connector's contacts are distributed in a uniform grid with 2mm spacing in both directions. This predictable pattern simplifies PCB layout, enables efficient signal routing, and allows engineers to achieve high contact density without complex custom footprints.
Q
What is the difference between LIF and ZIF connector mechanisms?
LIF (Low-Insertion-Force) connectors require a small amount of force to mate but provide a firm, secure connection. ZIF (Zero-Insertion-Force) connectors allow mating with virtually no force applied, making them ideal for delicate assemblies or frequent connect/disconnect cycles. Both types typically include a positive locking system to prevent accidental disconnection.
Q
Why is gold-over-nickel plating used in these connectors?
Gold-over-nickel plating is used because gold provides excellent electrical conductivity and outstanding resistance to oxidation and corrosion, ensuring a reliable signal path over the connector's lifetime. The nickel underlayer acts as a barrier to prevent gold migration and adds mechanical hardness, extending the connector's durability through many mating cycles.
Q
Are these connectors suitable for high-vibration environments such as aerospace?
Yes. These connectors are specifically designed with secure mating interfaces and positive locking systems that resist vibration and mechanical shock. This makes them well-suited for demanding aerospace and defense applications where connection reliability under extreme conditions is critical.
Q
Can these connectors be used in medical imaging equipment?
Absolutely. These connectors are used in the dense internal electronics of medical imaging systems such as MRI and CT scanners. Their compact footprint, high contact density, and reliable electrical performance make them an excellent fit for the sophisticated signal processing boards found in medical devices.
Q
How does the high-density design benefit high-performance computing applications?
In high-performance computing, maximizing the number of signal connections within a limited board area is essential for achieving high data throughput. The high-density 2x2mm grid design enables more parallel data lanes between daughtercards, memory modules, and accelerator cards, supporting faster bus speeds and reducing overall system size and weight.
