Frequently Asked Questions

Can you customize the pin length, pitch, or contact plating?
Yes, as a direct manufacturing factory, we offer full OEM/ODM customization services. We can adjust pin dimensions, change the pitch, and apply selective gold or tin plating based on your project requirements.
What is the standard Minimum Order Quantity (MOQ) for custom pin headers?
Our standard MOQ depends on the specific customization and tooling required, but we generally offer flexible terms to support both prototype pilot runs and high-volume mass production. Please contact our sales team for an accurate assessment.
Do your connectors comply with international environmental and safety standards?
Absolutely. All our electronic connectors are manufactured under strict ISO quality management systems and are fully compliant with RoHS, REACH, and UL standards.
What is the typical lead time for samples and volume orders?
Standard samples can usually be prepared and shipped within 3 to 7 business days. For mass production of customized volume orders, the lead time is typically 2 to 4 weeks, depending on material availability and production schedules.
Can you provide 3D models and engineering drawings for PCB layout design?
Yes, our engineering team provides comprehensive technical support, including 2D/3D CAD models (STEP/IGES) and detailed datasheets to help you streamline your PCB design and integration process.

Overview and Application Notes

  • Overview: Engineered for robust board-to-board interconnect solutions, our dual-row 4.00mm pitch through-hole pin header features a specialized bottom-entry design and tuning fork contacts. Designed to offer maximum mechanical stability and excellent electrical conductivity, it includes integrated locating pegs for precise PCB positioning and a polarization bump to prevent misinsertion. As an experienced OEM/ODM manufacturer, we provide comprehensive customization options—from pin length and plating to insulator materials—ensuring a perfect fit for your specific industrial, telecommunication, or consumer electronic applications.

  • Application Notes:

    • PCB Layout & Clearance: Ensure adequate clearance on the underside of the PCB to accommodate the bottom-entry profile and prevent electrical shorting.

    • Mating Orientation: Utilize the built-in polarization bump to align properly with the mating receptacle, avoiding damage to the tuning fork contacts.

    • Soldering Profile: Maintain standard wave soldering temperatures suitable for high-temperature thermoplastic insulators to prevent housing deformation.

    • Mechanical Support: For environments with high vibration, consider additional mechanical fastening to complement the locating pegs.
