Board to Board Connector
Industrial, IT Datacom
In high-density electronic designs, every millimeter and every connection counts. The CONSHARE 0.8mm pitch vertical BTB female receptacle isn't just another connector in your BOM — it's a purpose-built interface designed to solve the real challenges engineers face when packing more functionality into smaller form factors.
What sets this connector apart isn't just the 80-pin count or the surface-mount form factor. It's the combination of selective gold plating on critical contact areas, a high-temperature LCP housing rated to UL94V-0, and a 2.2N minimum pushout force per contact that gives you confidence your board-to-board connection won't fail under thermal cycling, vibration, or assembly stress.
Rated at 2 amps per pin (with 2 pins powered in parallel), this 80-pin connector gives you the headroom to handle both signal and moderate power distribution across a single interface. But here's what the spec sheet doesn't always tell you: the real value lies in derating. At your typical operating current — say 0.5–1A per signal line — you're running well below the rated limit, which means lower I²R losses, less self-heating, and more margin for thermal spikes in compact enclosures.
With a 225V AC / 318V DC rating, this connector handles far more than typical low-voltage board-to-board signaling. Why does that matter for your design? Because even if your application runs at 3.3V or 5V logic, having a high voltage-rated connector means:
Greater dielectric withstand between adjacent pins
Better protection against transient voltage events
More flexibility if your design evolves to include higher-voltage subsystems
This isn't just a number. A -55°C to +125°C operating range means this connector is qualified for environments that go well beyond standard commercial-grade components. Whether your product sees cold-start conditions in industrial equipment, elevated temperatures inside sealed consumer electronics, or thermal cycling in automotive under-hood applications, the contact resistance stays stable and the housing maintains its structural integrity.
At 5.3mm mated height (female side), this connector strikes a practical balance between low-profile design and mechanical robustness. It's low enough for slim form-factor products, but tall enough to accommodate:
Component height clearance on both boards
Thermal gap pads or heat spreaders between boards
Tolerance stack-up in volume manufacturing
The surface-mount design isn't just about saving board space — it's about manufacturing efficiency. This connector is optimized for standard SMT pick-and-place processes, with a co-planarity that works with standard reflow profiles. The tape-and-reel packaging (available on 100-position variants) integrates seamlessly into high-volume assembly lines without special handling.
With a 2.2N minimum pushout force per contact, you're getting a connector that holds up to the realities of PCB assembly. Whether it's the stress of mating/unmating during prototyping, the vibration of transport, or the thermal expansion/contraction cycles of reflow soldering, each contact stays firmly seated in its housing.
The housing is molded from Liquid Crystal Polymer (LCP) with a UL94V-0 flammability rating. LCP isn't the cheapest housing material, but it's the right choice for high-performance connectors because:
Exceptional dimensional stability — minimal warpage after reflow, ensuring consistent co-planarity
High heat resistance — survives multiple reflow cycles without degradation
Low moisture absorption — no popcorning issues during soldering
Excellent dielectric properties — maintains signal integrity at high frequencies
The 10µ" selective gold plating on the contact area is a deliberate engineering choice, not a marketing bullet. Gold provides the lowest, most stable contact resistance over the product's lifetime, especially in corrosive environments. But plating the entire contact in gold would be wasteful and expensive. Selective plating puts the gold only where it matters — the mating interface — while the solder tails use matte tin for reliable solder joints. You get the performance of gold where you need it, without paying for gold where you don't.
Underneath the plating, the contacts are formed from copper alloy. This base material delivers:
High electrical conductivity for minimal signal loss
Good mechanical spring properties for consistent normal force
Compatibility with both gold and tin plating systems
One size rarely fits all in connector design. The CONSHARE 0.8mm BTB platform is available in multiple configurations so you can match the connector to your design, not the other way around.

Mating Heights | Multiple stack heights from 7.0mm to 18.0mm total | Match with corresponding male header for your required board-to-board distance |
This 0.8mm pitch BTB connector excels in applications where density, reliability, and manufacturing efficiency all matter:
Smartphones and wearables where board space is at a premium
Tablet and laptop motherboards connecting to daughterboards
IoT devices with multiple PCBs in compact enclosures
PLC I/O modules requiring high signal density
Industrial sensor interfaces with mixed signal/power needs
Control boards needing reliable connections in temperature-varying environments
Infotainment system board-to-board connections
ADAS module interfaces
Body electronics controllers
Patient monitoring equipment
Diagnostic instrument internal connections
Portable medical devices requiring compact, reliable interconnects
When selecting the male header to pair with this female receptacle, pay attention to the total mating height. The 5.3mm female receptacle can pair with various male header heights to achieve total stack heights ranging from 7.0mm up to 18.0mm. This flexibility lets you optimize the board-to-board distance for component clearance, thermal management, or mechanical structure without switching connector platforms.
Before you lock in this connector for your design, run through this quick checklist to avoid common pitfalls:
Follow the recommended PCB land pattern — the 0.8mm pitch leaves little room for error
Account for the ±0.05mm PCB board tolerance in your footprint
Place fiducials near the connector for accurate SMT placement
Consider keep-out areas on both top and bottom sides
Verify the total mated height works with your enclosure and component clearances
Check that the male/female pair are from the same platform for proper mating
Plan for alignment features if blind mating is required in your assembly process
Calculate your total current per pin across all powered lines
Derate appropriately for high-temperature operation
Consider signal integrity for high-speed lines — 0.8mm pitch is good, but impedance control still matters
Verify voltage rating is sufficient for any power rails crossing the connector
Confirm your assembly house can handle the 0.8mm pitch fine-pitch SMT
Check packaging compatibility with your pick-and-place equipment
Plan for reflow profile compatibility with the LCP housing
A: The 0.8mm pitch and copper alloy contacts provide a solid foundation for high-speed signaling. For specific impedance requirements or multi-gigabit data rates, we recommend simulating your specific stack-up and trace geometry, as performance also depends heavily on PCB design and the mating pair configuration.
A: The selective gold plating is designed for multiple mating cycles while maintaining low contact resistance. For applications requiring frequent mating/unmating, consider a higher gold thickness option. Contact our engineering team for cycle life data specific to your plating selection.
