Board to Board Connector
Industrial, IT Datacom
Developed by CONSHARE, this vertical surface-mount dual-row board-to-board plug lineup is engineered to resolve compact PCB stacking interconnection challenges across portable medical electronics, industrial control sub-modules, consumer wearable hardware and automotive auxiliary circuit assemblies. Fixed 0.80mm center-to-center pitch paired with upright dual-contact layout prioritizes vertical space savings for miniaturized end-device internal wiring, a core design focus for OEMs pursuing slim product casing development.
Component construction splits insulating housing and conductive terminals into differentiated raw material grades to balance safety and circuit stability. Black UL94V-0 certified LCP thermoplastic forms the plug housing to satisfy global product fire-safety certification requirements, while signal contact and grounding terminals adopt two distinct copper-based alloys respectively. This separated metal formulation suppresses signal-to-power crosstalk commonly seen in single-alloy low-cost BTB alternatives.
Instead of rigid fixed-height specifications that restrict finished-product structural design, CONSHARE standardizes multi-tier mating height options spanning from 5.00mm up to 20.00mm. Every pre-defined height variant comes with calibrated internal terminal profiles, ensuring uniform retention force during repeated plug-in mating after full SMT assembly onto paired PCBs.
Nominal Total Mating Height | E Spec (mm) | H1 Spec (mm) | H2 Spec (mm) | H3 Spec (mm) |
|---|---|---|---|---|
5.00mm | 4.55 | 2.55 | 3.45 | 5.00 |
6.00mm | 4.55 | 2.55 | 3.45 | 6.00 |
10.00mm | 9.55 | 7.55 | 7.45 | 10.00 |
15.00mm | 14.55 | 12.55 | 7.45 | 15.00 |
20.00mm | 14.55 | 12.55 | 7.45 | 20.00 |

CONSHARE establishes seven split gold-plating grades for signal pins to eliminate unnecessary over-spec plating expenditure. Ultra-thin flash gold finishes suit static indoor consumer-grade equipment to cut component procurement cost, while heavy gold options from 1μ up to 30μ thickness target high-cycle plugging industrial/automotive interconnections to extend terminal service lifespan. All ground terminals deploy brass base with nickel underlayer + matte tin top plating, effectively blocking base metal oxidation during long-term warehouse storage before client assembly.
Plating Grade Code | Gold Thickness Grade | Optimal End-Use Environment |
|---|---|---|
S0 | Flash Gold | Static indoor low-frequency consumer electronics |
S1~S6 | 1μ/3μ/5μ/10μ/15μ/30μ Gold | Industrial, medical & automotive frequent-mating circuits |

All top-side PCB pad layouts for this 0.80mm pitch series feature factory pre-validated ±0.05mm unified tolerance margin. CONSHARE’s in-house verified PCB blueprint minimizes pick-and-place displacement during high-speed automated SMT processing, directly helping OEM manufacturers slash soldering open/short defect ratios in mass production. Additionally, overall plug body length scales proportionally with customized pin count; the modular structural design supports position configuration from 5 pins up to 70 pins without costly custom mold development for mid-volume prototype projects.
Full batch factory reliability testing calibrates the connector’s electrical performance to accommodate mixed low-current signal routing and limited auxiliary power feed circuits inside stacked PCBs. Capped maximum contact resistance and elevated insulation resistance thresholds preserve consistent signal integrity under transient current fluctuation, a critical feature for precision measuring and portable medical device internal wiring where signal distortion causes functional failure.
The complete connector assembly is engineered to maintain stable performance across -40°C ~ +105°C working temperature range. Such extensive thermal adaption makes the vertical SMT BTB plug viable for outdoor IoT hardware, vehicle cabin accessory modules and refrigeration control boards, locations with drastic seasonal or operational temperature swings.
Buyers can freely specify dual-row pin quantities starting at 5 positions and extending incrementally to 70 positions. The plug’s overall dimension automatically follows fixed pitch proportional scaling, drastically shortening CONSHARE’s prototype turnaround time compared to fully custom-molded non-standard BTB connectors; only mating height and pin number confirmation are required at the RFQ phase to lock finished component specifications.
Tape-and-reel packaging serves as the default shipping format, fully compatible with globally mainstream SMT feeder equipment from leading mounting machine manufacturers. This standard packing eliminates extra manual repacking overhead for clients’ automated production workflows, with custom loose bulk packaging available for small-batch prototype builds via separate negotiation.
Multi-Dimension Customization Shortens New Product R&D Cycles: Configurable pin count, mating height and plating specs reduce repeated prototype revision costs and accelerate OEM’s end-product market launch schedule.
Tiered Material Specification Controls Total BOM Spend: Graded gold plating and split base metal design avoid redundant high-cost plating over-specification, optimizing client component budget without compromising required circuit reliability grade.
Pre-Verified PCB Layout Eliminates Third-Party Design Fees: CONSHARE’s internally validated footprint removes outsourced PCB layout modification expense and lowers mass-production reject loss caused by soldering mismatches.
Global Compliance Ready for Cross-Border Sales: All production batches pass standardized electrical safety screening, simplifying CE/FCC certification procedures for finished goods targeting EU and North American market distribution.
