Card Edge Connector
Industrial, IT Datacom
The CONSHARE PCIe 3.0 64-pin low-angle clamp SMT connector handles board-to-card edge connections where vertical clearance is tight and retention still matters. With a 1.00 mm pitch across 64 positions, it fits standard PCIe x4 edge card footprints while the low-angle clamp body keeps the mated profile close to the PCB. LCP housing, gold-plated copper alloy contacts, and tray packing make it a practical drop-in for high-density motherboards, embedded systems, and industrial computing platforms that need reliable signal integrity without oversized hardware.
The clamp-style body sits at a shallow angle after mating, which is the real advantage here. In 1U servers, compact industrial PCs, and embedded IoT gateways, every millimeter above the board counts. A conventional vertical connector can force a taller enclosure or awkward cable routing; this low-angle design lets the edge card run nearly parallel to the motherboard, freeing headroom for heatsinks, shields, or adjacent components.
Retention comes from the spring clamp action rather than a simple friction fit. That matters during shipment and vibration: once the card is seated, the contact pair maintains a minimum extraction force that resists loosening from thermal cycling or mechanical shock. The insertion force is capped at 1.15 N per contact pair, so assembly technicians do not need excessive pressure to seat the card, reducing the risk of cracked solder joints or misaligned PCBs during manual or semi-automated insertion.
CONSHARE uses an LCP housing loaded with 30% glass fiber and rated UL94V-0. The material holds dimensional stability through lead-free reflow profiles, so the contact pitch and coplanarity stay within tolerance after soldering. For boards that see repeated thermal swing — think outdoor digital signage, factory automation controllers, or automotive edge gateways — that stability translates to fewer intermittent contacts over the product life.
The terminals are copper alloy, 0.25 mm thick, with selective plating: gold on the contact area for low and stable resistance, tin on the solder area for wetting, and a nickel underplate across the whole terminal for corrosion barrier and wear resistance. The result is a 30 mΩ maximum contact resistance and a 1.1 A per-pin current rating, enough for PCIe 3.0 signal lines and auxiliary power delivery without running the connector near its limit.
Property | Value | Why It Matters |
|---|---|---|
Contact pitch | 1.00 mm | Matches standard PCIe x4 card edge spacing |
Contact resistance | ≤ 30 mΩ | Stable signal levels across the link |
Insulation resistance | ≥ 1000 MΩ | Low leakage between adjacent pins |
Dielectric strength | 500V AC/min | Adequate margin for board-level isolation |
Current rating | ≥ 1.1 A per pin | Headroom for signal and light power |
Operating temperature | -25°C to +85°C | Covers commercial and light industrial environments |
Durability | 50 cycles min | Supports field service and test fixtures |
Not every PCIe edge connector needs a clamp. Standard SMT versions cost less and work fine in static office equipment. The low-angle clamp format earns its place when:
The board sits in a shallow chassis and the mated card must stay low.
The product faces vibration, shock, or frequent thermal cycling.
Field technicians may swap cards, and you want the connector to survive more mating cycles than a basic friction socket.
One detail buyers often miss is solderability. The tin-over-nickel solder tail on this part wets well with SAC305 paste, but the footprint still needs the correct pad geometry and paste stencil. CONSHARE provides recommended PCB layout guidance aligned with the part geometry so your CM does not have to reverse-engineer the land pattern.
We produce these connectors on automated stamping, plating, and insertion lines with in-process checks for contact force, coplanarity, and plating thickness. Each lot is sampled for contact resistance, insulation resistance, and dielectric withstand before tray packing.
The standard tray pack keeps parts flat and protected through shipping and SMT line feeding, which is important for a connector with 64 fine-pitch pins that can bend if dumped loose in a bag.
Standard lead time runs 4–6 weeks for catalog configurations. For programs with predictable pull schedules, CONSHARE can set up rolling forecast releases to shorten effective lead time and avoid last-minute air freight.
While BR0641X57XXXX covers the common PCIe 3.0 x4 configuration, some programs need a different plating thickness, a specific housing color for visual identification, or modified tape-and-reel packaging for high-speed pick-and-place. CONSHARE supports:
Gold flash up to 30 µ" on contact area
Halogen-free or RoHS-only material variants
Embossed tape-and-reel alternative to tray
Marked housings with customer-specific locator keying
Custom changes are evaluated against the existing tooling to keep NRE low and timing predictable.
This connector shows up in designs where a PCIe add-in card needs to stay low and secure: industrial motherboards, network appliances, edge AI boxes, video capture cards, and COM Express carrier boards. It also works well in test fixtures and programming stations where boards are inserted and removed repeatedly, since the 50-cycle durability rating outlasts basic sockets.
It is electrically compatible with PCIe 3.0 data rates. For PCIe 4.0 or 5.0 designs, CONSHARE recommends connectors specifically validated for higher insertion loss and crosstalk budgets.
Yes, the 1.00 mm pitch and 64-pin count match the PCIe x4 card edge footprint.
Standard material is RoHS and halogen-free compliant. Confirm the exact suffix when ordering if your project needs a specific environmental certification.
Tray pack is standard. Tape-and-reel is available as a custom option for automated assembly lines.
