Card Edge Connector
Industrial, IT Datacom
The PCIe 4.0 98-pin DIP connector represents a critical interconnect solution for modern high-speed computing platforms. Designed to meet the rigorous demands of PCI Express Gen 4 signaling environments, this connector delivers the electrical and mechanical reliability required for server, storage, and high-performance computing applications.
CONSHARE has engineered this connector to address the specific challenges of high-speed differential signaling—maintaining signal integrity across the interconnect path while providing the mechanical robustness needed for repeated mating cycles in enterprise environments. The 98-position configuration supports x16 PCIe lane architectures commonly found in add-in cards, motherboards, and expansion backplanes.
The connector is built to support PCIe 4.0 signaling speeds up to 16 GT/s, making it suitable for bandwidth-intensive applications including AI accelerators, high-performance computing clusters, and data center networking equipment. The 1.00mm contact pitch provides the controlled impedance environment necessary for maintaining signal integrity at these elevated frequencies.
The contact mating area features 15 microinches of gold plating over a suitable underplating. This gold thickness strikes an optimal balance between cost and performance—providing excellent corrosion resistance, stable contact resistance over the product lifetime, and reliable performance through the rated 50 mating cycles.
Through-hole DIP termination offers superior mechanical retention compared to surface-mount alternatives, with a terminal retention force of ≥4.9N per contact. This makes the connector particularly well-suited for applications subject to vibration, thermal cycling, or mechanical shock. The 2.3mm tail length is optimized for standard PCB thicknesses, providing consistent solder joint formation during wave soldering processes.
The connector body is molded from high-temperature halogen-free plastic, supporting wave soldering at 260°C for 3–5 seconds without material degradation. The -40°C to +105°C operating temperature range ensures reliable performance across diverse deployment environments, from cold-start data centers to thermally challenging industrial settings.

In server environments, this connector is commonly used for PCIe add-in card interfaces—supporting network interface cards (NICs), host bus adapters (HBAs), RAID controllers, and GPU accelerators. The robust DIP termination ensures reliable connections in high-vibration chassis environments typical of rack-mount servers.
Enterprise storage arrays and NVMe SSD backplanes benefit from the connector's stable contact resistance and high mating cycle durability. The halogen-free construction also aligns with enterprise sustainability requirements.
The wide operating temperature range and mechanical robustness make this connector suitable for industrial PCs, edge computing devices, and transportation systems where environmental conditions are less controlled.
Routers, switches, and other networking infrastructure that incorporate PCIe-based data plane processing can leverage this connector's signal integrity performance for reliable high-speed data throughput.
CONSHARE maintains rigorous quality control across the manufacturing process. Each connector undergoes electrical testing to verify contact resistance (≤30mΩ initial, ≤50mΩ after environmental exposure) and insulation resistance (≥1000MΩ). The 500V AC dielectric withstand voltage rating confirms adequate creepage and clearance distances for safe operation in standard equipment designs.
The connector meets applicable RoHS and halogen-free requirements, supporting customers' environmental compliance objectives.
The connector is supplied in tray packaging optimized for automated assembly processes. Each tray contains 30 pieces, with 12 trays per inner box (360 pieces total) and 4 inner boxes per carton (1,440 pieces total). Antistatic trays and PE film protection ensure components arrive in optimal condition for surface-mount or wave-solder assembly.
When specifying this connector for your design, consider the following factors:
PCB Thickness Compatibility: The 2.3mm tail length is designed for standard PCB thicknesses. Verify your PCB thickness falls within the recommended range for proper through-hole solder joint formation.
Mating Cycle Requirements: The connector is rated for 50 mating cycles. For applications requiring more frequent card swaps, evaluate your expected lifecycle requirements against this specification.
Soldering Process: The connector supports wave soldering at 260°C for 3–5 seconds. For reflow processes or different soldering profiles, please consult CONSHARE's application engineering team.
Environmental Considerations: The -40°C to +105°C operating range covers most industrial and enterprise applications. For extreme environments beyond this range, contact CONSHARE for alternative material options.
A: Thicker gold plating (30μ″) provides additional durability for applications with higher mating cycle requirements or more aggressive environmental conditions. The 15μ″ option offered here provides an excellent cost-performance balance for most enterprise and industrial applications, delivering reliable performance through the rated 50 mating cycles.
A: Yes. PCIe connectors are backward compatible. This connector's electrical design supports PCIe 4.0 signaling (16 GT/s) and is fully compatible with PCIe 3.0 (8 GT/s), PCIe 2.0 (5 GT/s), and PCIe 1.0 (2.5 GT/s) signaling.
