Board to Board Connector
Industrial, IT Datacom
In today's densely packed electronic designs, every millimeter counts. The CONSHARE 0.8mm pitch board-to-board male connector delivers high-density interconnect solutions without compromising on mechanical robustness or electrical integrity. Designed for surface-mount assembly and optimized for 5.0mm stacking heights, this 80-pin connector bridges PCBs in applications where space is premium but signal reliability is non-negotiable.
Engineered with LCP housings rated UL94V-0 and gold-plated copper alloy contacts, this connector is built to perform across a wide temperature range from -40°C to +105°C. Whether you're designing consumer electronics, industrial control modules, or medical devices, the CONSHARE BTB connector series provides the interconnect reliability your product demands.
At 0.8mm pitch, this connector achieves impressive pin density—80 contacts in a compact footprint—while maintaining 500V AC dielectric withstand capability and 50mΩ maximum contact resistance. The result? More I/O channels in less board space without sacrificing electrical isolation or signal integrity.
The dual plating system sets this connector apart: gold plating in the contact mating area ensures low contact resistance and corrosion resistance, while flash plating in the solder area optimizes wetting during SMT reflow. Combined with nickel underplating on the cap, you get a connector that survives both the assembly line and years of field operation.
Rated for operation from -40°C up to +105°C, this connector doesn't just survive lab conditions—it thrives where your product actually operates. Whether deployed in outdoor equipment, industrial enclosures, or devices with internal heat buildup, the LCP housing and copper alloy contacts maintain dimensional stability and electrical performance across the full temperature spectrum.
The 0.5A current rating per contact isn't just a number—it's the result of careful contact geometry and material selection. The copper alloy contacts provide the spring force needed for consistent mating, while the gold plating maintains low contact resistance even after thousands of insertion cycles. This balance of mechanical spring properties and electrical conductivity is what separates a reliable BTB connector from one that fails in the field.
Liquid Crystal Polymer (LCP) was chosen for a reason. Its UL94V-0 flammability rating meets the safety requirements of most commercial and industrial applications. More importantly, LCP exhibits exceptional dimensional stability during SMT reflow—critical for fine-pitch connectors where even minor warpage can cause misalignment and solder joint failures.
The connector's mechanical design accounts for real-world assembly variations. The guide features and polarized housing help prevent mis-mating during production, while the overall structure provides the mechanical retention needed to withstand vibration and shock in end applications.
CONSHARE offers this 0.8mm pitch BTB connector platform across a range of pin counts and stacking heights, giving you design flexibility without requalifying a new connector family.
Pin Count | Connector Length (A) | Body Width (B) | Width w/ Cap (C) | Overall Height (D) |
|---|---|---|---|---|
20 Pin | 9.80 mm | 3.20 mm | 4.80 mm | 8.20 mm |
30 Pin | 13.80 mm | 3.20 mm | 4.80 mm | 8.20 mm |
40 Pin | 17.80 mm | 3.20 mm | 4.80 mm | 8.20 mm |
50 Pin | 21.80 mm | 3.20 mm | 4.80 mm | 8.20 mm |
60 Pin | 25.80 mm | 3.20 mm | 4.80 mm | 8.20 mm |
70 Pin | 29.80 mm | 3.20 mm | 4.80 mm | 8.20 mm |
80 Pin | 33.80 mm | 3.20 mm | 4.80 mm | 8.20 mm |
100 Pin | 41.80 mm | 3.20 mm | 4.80 mm | 8.20 mm |
Stacking height options: 5.0mm through 8.0mm mated heights are available to accommodate different board-to-board spacing requirements.
Note: PCB board tolerance of ±0.05mm should be accounted for in your layout design.
In PLC modules and industrial I/O boards, this 0.8mm pitch BTB connector handles both signal and low-power connections between the main controller board and interface cards. The -40°C to +105°C operating range ensures reliable performance in factory floor environments where temperature fluctuations are the norm.
For portable medical equipment where size and weight are critical, the high-density 80-pin configuration allows designers to pack more functionality into smaller form factors. The LCP housing's UL94V-0 rating and gold-plated contacts meet the reliability standards expected in medical applications.
In compact consumer devices where board space is at a premium, the 5.0mm mated height profile enables slimmer product designs while still providing sufficient I/O for display interfaces, sensor arrays, and power management connections.
While not designed for under-hood extremes, this connector excels in cabin electronics—infotainment systems, driver display modules, and connectivity control units—where the wide temperature range and vibration resistance keep signals flowing reliably year after year.
Determine your total signal and power requirements first, then select the smallest pitch that can handle your current and voltage needs. At 0.8mm pitch with 0.5A per contact, this connector handles most signal-level and low-power applications. If you need higher current per pin, consider a larger pitch platform.
Measure the distance between your two PCBs in the final assembly. Remember to account for component heights on both boards and any mechanical tolerance stack-up. CONSHARE offers mated heights from 5.0mm to 8.0mm in this 0.8mm pitch family.
Surface-mount connectors like this one are optimized for automated SMT assembly lines. Ensure your PCB pad design matches the recommended footprint and that your reflow profile is compatible with LCP housing materials.
Temperature extremes: This connector handles -40°C to +105°C—verify this covers your application's operating range with margin.
Vibration and shock: The mechanical retention and contact normal force are designed for typical consumer and industrial applications; for high-vibration environments, consider additional mechanical securing options.
Humidity and corrosion: Gold-plated contacts provide good corrosion resistance for most indoor and protected outdoor environments.
CONSHARE maintains standard pin counts (20, 30, 40, 50, 60, 70, 80, 100) in production, which helps with lead times and pricing stability. Custom pin counts are available but may require minimum order quantities and longer lead times.
At CONSHARE, every 0.8mm pitch BTB connector undergoes rigorous testing to ensure it meets our performance specifications before it reaches your production line. Our quality control process includes:
Contact resistance testing to verify electrical performance
Insulation resistance and dielectric withstand testing for electrical safety
Temperature cycling from -40°C to +105°C to validate environmental robustness
Mechanical mating cycle testing to ensure long-term durability
Solderability testing to confirm SMT assembly compatibility
The nickel underplating on the cap and the dual plating system on contacts aren't just material choices—they're reliability features that extend the service life of the connector in real-world operating conditions.
A: Yes, with a 0.5A current rating per contact, you can allocate several pins for power distribution across the 80-pin array. We recommend distributing power across multiple contacts for higher current requirements and consulting with our engineering team for specific power delivery applications.
A: This connector uses selective plating: gold in the contact mating area for low resistance and corrosion resistance, and flash plating in the solder area for optimal solder wetting. This approach balances performance and cost—you get gold where it matters electrically, and solder-optimized plating where it matters for assembly.
A: CONSHARE provides recommended PCB layout drawings with each connector specification. The general guideline is to account for ±0.05mm PCB board tolerance in your pad design. Our application engineers can also review your layout before production to ensure optimal solder joint formation.
