Board to Board Connector
Industrial, IT Datacom
Modern PCB designs are under constant pressure to do more with less space. Every millimeter of board real estate counts, and the connector you choose directly impacts your overall system density, assembly yield, and long-term reliability.
The CONSHARE 1.00mm pitch single-row SMT connector addresses exactly this challenge. Designed in a 180° vertical orientation with a high-temperature LCP (Liquid Crystal Polymer) housing, this pin surface-mount connector delivers the density required for compact electronic assemblies without compromising on mechanical stability or thermal performance.
Unlike bulkier 2.54mm pitch alternatives that consume excessive board space, the 1.00mm center-to-center spacing enables up to 60% more signal paths in the same linear footprint. This makes it a natural fit for applications where miniaturization is non-negotiable—wearables, portable medical monitors, IoT sensors, and space-constrained automotive electronics.
The housing material is often the most overlooked factor in connector selection—yet it directly determines whether your assembly survives the reflow oven. CONSHARE specifies LCP for this connector series, and here’s why it matters:
Standard thermoplastics like nylon or PBT can absorb moisture and outgas during soldering, leading to blistering, warping, or dimensional shifts that compromise coplanarity. LCP, by contrast, withstands peak reflow temperatures of 260°C to 280°C without deformation. Its low coefficient of thermal expansion ensures the housing maintains critical dimensional stability throughout the soldering process, reducing the risk of open circuits or misalignment.
For engineers running lead-free, RoHS-compliant assembly lines, this is not a nice-to-have—it’s a requirement. LCP handles the thermal stress that would destroy lesser materials.
The vertical (180°) mounting configuration offers distinct advantages depending on your system architecture:
Stacked board designs: When PCBs are arranged in parallel layers, vertical connectors enable direct board-to-board interconnect with predictable, repeatable mating heights.
Edge-accessible interfaces: For modules that need to connect perpendicular to the main board, the vertical orientation provides a clean, low-profile solution.
Automated assembly: The vertical SMT footprint is fully compatible with standard pick-and-place equipment, supporting high-throughput production lines.
Single-row design keeps routing straightforward. With 15 positions arranged in a single line, trace routing on the PCB remains simple and predictable—no complex breakout patterns, no via fan-out headaches. This is particularly valuable for sensor modules, control interfaces, and diagnostic ports where pin counts are moderate but board space is tight.
The connector pitch you select has cascading effects on your entire design. Here’s a decision framework:
Consideration | 1.00mm Pitch | 1.27mm Pitch | 2.54mm Pitch |
|---|---|---|---|
Board Space Efficiency | Highest density—ideal for wearables, mobile devices | Good balance—suits industrial IoT, medical monitors | Lowest density—best for prototyping, legacy systems |
Assembly Complexity | Requires precise stencil and reflow control | Moderate—forgiving enough for most SMT lines | Easiest—supports hand-soldering and rework |
Current Capacity | Lower (signal-level applications) | Moderate (1.5–2A per pin) | Highest (3A+) |
Signal Integrity | Requires careful routing to manage crosstalk | Better margin for high-speed signals | Most forgiving |
CONSHARE’s recommendation: Choose 1.00mm pitch when board space is the primary constraint and your signals are digital or low-frequency analog. For power delivery or high-speed differential pairs (>1 GHz), evaluate your routing density and shielding requirements carefully.
Working with fine-pitch SMT connectors demands attention to process parameters:
Stencil design: Use laser-cut stencils with apertures sized appropriately for the pad geometry. Avoid hand-soldering 1.00mm pitch components—the margin for error is simply too small.
Reflow profiling: The LCP housing can tolerate the thermal cycles, but ensure your profile matches the solder paste manufacturer’s recommendations to prevent tombstoning or insufficient wetting.
PCB pad design: Maintain symmetrical pad sizes to promote even solder wetting across all pins. Asymmetrical pads are a leading cause of assembly defects in fine-pitch components.
Tape-and-reel packaging: CONSHARE supplies these connectors in tape-and-reel format, compatible with automated placement systems and including pickup caps where applicable.
A medical device OEM developing a continuous glucose monitor needed to reduce PCB size by 40% to fit a new form factor. Switching from 2.00mm to 1.00mm pitch connectors freed up critical board space while maintaining the vibration resistance required for patient-worn devices. The LCP housing additionally provided the chemical resistance needed to withstand alcohol-based sanitization wipes.
An automotive supplier designing blind-spot detection sensors required connectors that could survive under-hood temperature extremes. The CONSHARE 1.00mm vertical SMT connector’s LCP housing and robust contact system delivered reliable signal transmission across the -40°C to +105°C operating range. The single-row configuration simplified PCB routing in the compact sensor housing.
A drone manufacturer needed to interconnect the main flight controller board with a peripheral sensor array. The vertical SMT orientation enabled a clean, stackable board-to-board connection with minimal height penalty, while the 15-pin count provided sufficient I/O for the sensor suite.
This connector is designed for board-to-board or wire-to-board applications. It mates with corresponding receptacle connectors on the opposing PCB or cable assembly. Confirm the mating connector specifications with CONSHARE’s technical team to ensure compatibility.
Pad geometry should be designed to match the connector’s termination footprint. CONSHARE provides recommended land patterns upon request. Following the recommended footprint is critical—deviations can lead to solder bridging or insufficient fillet formation.
LCP offers excellent dimensional stability over temperature and humidity cycling. It does not absorb moisture like nylon-based housings, which means no hygroscopic swelling that could stress solder joints over time-. This translates to better field reliability in high-humidity environments.
Yes. While the 15-pin configuration is highlighted here, CONSHARE offers this connector series in a range of pin counts to suit different application requirements. Custom configurations are available upon request.
The standard contact plating is tin over nickel, providing a cost-effective solution with good solderability and corrosion resistance. Gold plating is also available for applications requiring lower contact resistance or enhanced durability in harsh environments.
The connector housing incorporates polarization features to prevent incorrect insertion. Always verify the mating orientation during assembly—forcing a misaligned connection can damage contacts and compromise reliability.
