Compared with SMT surface-mounted pin headers and common double-ended pin headers, our double row double-ended through-hole soldering pin headers have prominent comprehensive advantages in structural stability, assembly adaptability, service reliability, and cost performance, solving many pain points in electronic assembly and circuit connection.

Excellent Mechanical Stability & Anti-Vibration Performance: Different from surface-mounted connectors that only rely on surface solder paste bonding, the through-hole soldering structure allows pins to completely penetrate the PCB board and be fully wrapped and fixed by solder on the back of the board. This forming method greatly improves the tensile resistance, torsion resistance and anti-vibration ability of the connector. It can effectively resist loose connection and pin detachment caused by equipment vibration, mechanical impact and frequent cable pulling, which is especially suitable for equipment working in vibrating industrial environments. The double-ended pin structure further enhances the overall structural balance, avoiding unilateral stress deformation and improving the overall assembly firmness.

Strong Process Adaptability & Low Assembly Threshold: The product is compatible with automated industrial mass production and small-batch manual processing. It can be perfectly adapted to wave soldering assembly lines to realize efficient batch processing, greatly improving production efficiency and reducing labor costs. For small-batch customized products and prototype debugging, manual electric iron soldering can also complete precise installation with low error rate and simple operation. The through-hole installation has strong tolerance for PCB hole position deviation and pin position error, with high assembly fault tolerance rate and low defective rate, effectively reducing production and after-sales costs.

Durable & High Temperature Resistant with Long Service Life: The high-quality phosphor bronze pins with tin-plated surface have excellent oxidation resistance and corrosion resistance, which can prevent pin oxidation and poor contact caused by long-term exposure to air. The PA66 high-temperature resistant base can resist the high temperature impact during soldering and long-term high-temperature operation of equipment, without aging, deformation or cracking. The product maintains stable electrical and mechanical performance in long-term working state, with low failure rate and long service cycle, reducing the frequency of equipment maintenance and parts replacement.

Stable Electrical Transmission & High Safety: Ultra-low contact resistance ensures lossless transmission of power signals and high-frequency signals, avoiding signal distortion, delay and power loss. Excellent insulation performance completely isolates current between pins, effectively preventing short circuit, leakage and other electrical faults. The standardized structural design ensures consistent electrical performance of each product, providing reliable guarantee for the stable operation of electronic systems.

High Cost Performance & Wide Compatibility: With standardized industrial production, the product has stable quality and moderate price, realizing high cost performance in mass application. It is compatible with various mainstream PCB board designs, insulating materials and assembly processes, and can be matched with various terminal equipment and wire harness accessories. The modular design supports customized pin number and pin length, meeting the personalized connection needs of different products.

Benefiting from its high stability, strong adaptability and high reliability, this double row double-ended through-hole soldering pin header is widely used in civil consumer electronics, industrial control equipment, intelligent Internet of Things devices, electronic instrumentation and other fields, covering most conventional circuit connection scenarios.

Industrial Control & Automation Equipment: It is applied to PLC control boards, industrial sensor modules, servo drive equipment, and industrial communication terminals. In complex industrial environments with frequent vibration and temperature changes, its anti-vibration and high and low temperature resistance can ensure long-term stable circuit connection and avoid equipment shutdown and failure caused by loose connectors.

Smart Home & Consumer Electronics: Suitable for smart control panels, intelligent lighting modules, household appliance control boards, and wearable electronic devices. It realizes stable internal circuit connection of household electronic equipment, with safe and reliable performance, meeting the long-term standby and frequent use requirements of household equipment.

Q1: What is the mounting method of this pin header? Is it compatible with automated production?

A1: This product adopts standard through-hole soldering mounting method. The pins vertically penetrate the PCB through holes and are fixed by soldering on the back of the board. It is fully compatible with industrial automated wave soldering production lines and also supports manual soldering installation, adapting to mass production and small-batch prototype debugging scenarios.

Q2: What are the advantages of through-hole soldering compared with SMT patch type pin headers?

A2: Through-hole soldering structure has higher mechanical strength and anti-vibration ability, not easy to fall off and loose. It has higher fault tolerance during installation, simpler maintenance and rework, and better heat dissipation performance, which is more suitable for high-current and vibrating working environments. SMT patch type is only suitable for static and low-current lightweight equipment, with poor shock resistance.
