The single-slot 0.8mm BTB (Board-to-Board) female connector with H3.8 stack height is an interconnect component suitable for medium-to-high density connection scenarios. The 0.8mm pitch balances connection density and assembly convenience, the 3.8mm stack height adapts to the layout of slim devices, and the single-slot structure meets the requirements of precise docking and simplified assembly. It is often used as a key component for signal and power transmission between PCB boards. Detailed analysis based on industry general standards is as follows:
Core Parameters & Structural Features
0.8mm Pitch
As a mainstream medium-precision specification in electronic devices, compared with 0.5mm pitch, it can reduce PCB routing difficulty and the risk of alignment errors during assembly, minimizing poor contact issues. Meanwhile, it adopts a double-row pin design, with common configurations such as 2×8P to 2×60P, which can meet the multi-signal channel transmission needs of medium and high-end electronic devices, balancing practicality and economy.
Single-Slot & Female Connector
The "single-slot" means the connector has only one mating slot. When docked, it can form basic positioning with the male connector of the same specification, ensuring docking accuracy while simplifying plugging and unplugging operations. It is suitable for device scenarios with moderate anti-vibration requirements. As a "female connector", it is the passive mating end with pin sockets, which must be paired with the 0.8mm BTB male connector of the same specification and soldered on the PCB board to form a complete transmission link.
H3.8 Stack Height
The 3.8mm mating stack height of male and female connectors is a transitional specification from slim to standard height. It can not only avoid the insufficient pulling force of ultra-slim models (such as below H2.0) but also not occupy too much internal space of the device like models above H5.0. It is suitable for the inter-board stacking needs of devices with moderate thickness, such as tablets and small industrial controllers.
Material Selection & Core Performance
Material Matching
Contact terminals are mostly made of copper alloy or phosphor bronze, with selective gold plating on the surface. This not only reduces contact resistance to ensure stable signal transmission but also the gold plating layer can improve oxidation resistance and wear resistance. Insulators are generally made of LCP engineering plastic, which can withstand the high temperature of reflow soldering in the SMT mounting process and meets the UL94 V-0 flame retardant standard, ensuring higher safety.
Key Performance
The contact resistance of this type of female connector can usually be controlled within 50mΩ, the insulation resistance is not less than 10MΩ, and the rated current is generally 0.5A, which can meet the power transmission needs of low-to-medium power devices. The operating temperature range is mostly -55℃ to 85℃, which can adapt to most indoor and outdoor temperature conditions. The plugging life can generally reach hundreds of times, which can meet the plugging needs during daily equipment maintenance, and most products comply with environmental standards such as RoHS and REACH.
Typical Application Scenarios
With balanced performance, this type of connector is widely used in various fields. In the consumer electronics field, it can be used for connecting the main board and sound module of mid-to-high-end smart speakers, and the main control board and display module of portable game consoles. In the industrial field, it is suitable for inter-board signal transmission of small sensors and PLC modules, coping with normal working conditions in industrial environments. In automotive electronics, it can be used for internal connection of auxiliary electronic components such as on-board small screens and on-board chargers. In addition, it is also commonly used in medical auxiliary equipment such as portable blood glucose meters and small electrocardiogram monitors, as well as the docking between the core board and functional modules of office equipment such as printers and scanners.
