Product Introduction

In the intricate architecture of electronic devices, the fundamental connection between components often relies on one of the most essential and versatile building blocks: the pin header and socket system. YFS Technology (SZ) Co., Ltd. presents the PinConnect series—a comprehensive portfolio of precision-engineered male pin headers and corresponding female sockets designed to establish robust, reliable, and cost-effective board-to-board or board-to-wire connections. These components form the backbone of countless electronic assemblies, serving as the primary interface for power, signal, and data transfer in applications ranging from simple prototypes to complex, high-volume commercial products.

The PinConnect system addresses the universal need for a standardized, yet highly customizable, interconnection method. Unlike proprietary connectors, pin headers offer unparalleled design flexibility, allowing engineers to specify the exact pin count, orientation, spacing, and mounting style required for their application. YFS Technology elevates this standard with a focus on manufacturing precision, material integrity, and long-term reliability. Our PinConnect series ensures that these seemingly simple components do not become the weak link in your system, providing consistent electrical performance, secure mechanical mating, and resilience against environmental stress factors common in industrial, automotive, and consumer environments.

Product Features

The PinConnect system is engineered with features that guarantee performance and simplify integration:

Precision-Formed Contacts: Male pins and female socket contacts are manufactured from high-conductivity copper alloys and precision-stamped or machined to ensure consistent dimensions, optimal spring force in sockets, and low, stable contact resistance.

Durable Housing Construction: Headers and sockets feature housings made from high-temperature, UL94-rated plastics (such as PA6T, PA9T, or PBT). These materials provide excellent dimensional stability across temperature fluctuations, resistance to soldering heat, and long-term durability.

Comprehensive Configuration Matrix: Available in single-row, double-row, and multi-row formats. Offered in standard pitches (1.27mm, 2.00mm, 2.54mm), with straight (vertical) or right-angle orientations. Options include through-hole (THT) or surface-mount (SMT) terminations, with or without polarization/keying features.

Secure Locking Mechanisms: Select socket models include friction locks, push-pull locks, or screw locks with mating headers to ensure a vibration-resistant connection, critical for automotive and industrial applications.

Optimized for Manufacturing: Provided in tape-and-reel packaging for SMT types or anti-static tubes/bags for THT types, fully compatible with automated assembly processes to ensure high placement accuracy and yield.

Product Advantages

Choosing the YFS PinConnect system delivers significant benefits throughout the product lifecycle:

Unmatched Design Freedom: The modular nature of pin headers allows engineers to create custom interconnect solutions without custom tooling. Pin count, row spacing, and mounting style can be tailored precisely to the PCB layout and mechanical enclosure.

Proven Reliability & Cost-Effectiveness: As a mature, widely adopted technology, pin header systems offer an excellent balance of performance and cost. YFS's enhanced manufacturing and material quality provide superior reliability within this cost-effective paradigm.

Simplified Assembly & Rework: The straightforward design facilitates easy manual or automated assembly. Components are also generally easier to rework or replace in the field compared to more complex, sealed connector systems.

Broad Compatibility & Second-Sourcing: Adherence to industry-standard dimensions ensures compatibility with a vast ecosystem of existing sockets, shrouds, and cable assemblies, mitigating supply chain risk.

Scalability from Prototype to Production: Ideal for prototyping due to availability and ease of use, and seamlessly scales into mass production with automated assembly options.

Product Applications

PinConnect headers and sockets are ubiquitous across the electronics industry:

Development Kits & Evaluation Boards: The standard interface for connecting expansion boards, sensor modules, and debugging interfaces to microcontroller and FPGA development platforms.

Internal Board-to-Board Connections: Used to stack daughterboards (e.g., memory modules, WiFi/Bluetooth cards) onto a mainboard in computers, networking gear, and industrial controllers.

Power Supply Connections: Commonly used to bring low-voltage DC power from a supply board to system boards, often with higher-current-rated pins.

Consumer Electronics: Found inside appliances, audio/video equipment, and smart home devices for internal wiring harness connections and modular sub-assemblies.

Industrial Control Systems (ICS): Connect I/O modules, communication boards, and indicator panels within PLCs, HMIs, and automation equipment.

Automotive Sub-Modules: Used in non-safety-critical electronic control units (ECUs) for infotainment, climate control, and lighting, where cost and flexibility are key.

Telecommunications Infrastructure: Provide inter-board connectivity within routers, switches, and base station units where modularity is required for different configurations.

FAQ Section

Q: What is the difference between shrouded and unshrouded headers?
A: A shrouded (or box) header has a plastic barrier around the pins, which provides polarization (prevents incorrect mating) and protects the pins from physical damage. An unshrouded header is just the pins on a base. Shrouded headers mate with corresponding shrouded sockets, while unshrouded headers can mate with sockets or be used with discrete jumper wires.

Q: How do I choose the right current rating for my pin header?
A: The current rating depends on the pin material, cross-sectional area, and plating. Standard 2.54mm pitch pins typically handle 1-3A. For higher currents, look for headers with thicker pins or those made from specific high-current alloys. Always consult the datasheet and consider derating for temperature and continuous operation.

Q: Are your surface-mount (SMT) pin headers suitable for reflow soldering?
A: Yes, our SMT PinConnect headers are manufactured with high-temperature plastic housings and are fully compatible with standard lead-free reflow soldering profiles. We provide recommended footprint and stencil designs to ensure a reliable solder joint.

Q: Can I get custom pin header lengths or unusual pin arrangements?
A: Yes, YFS Technology offers custom services. We can produce headers with custom pin counts, missing pins (for keying), custom row spacings, and unique colors for identification. Minimum order quantities (MOQs) apply for custom configurations.

Q: What plating options are available for the contacts?
A: Standard options include tin (Sn) plating for general purpose, cost-sensitive applications, and gold flash over nickel (Ni/Au) for applications requiring better corrosion resistance, lower contact resistance, and higher mating durability (e.g., frequently connected test points).

Q: Do you offer matching wire harness sockets/cables?
A: Yes. For many of our standard PinConnect header series, we offer compatible crimp-style or IDC (Insulation Displacement Connector) socket housings and pre-made cable assemblies. This provides a complete interconnect solution from board to wire.
