Electronic Connectors: Precision Board-to-Board, Wire-to-Board & FPC Interconnects

 

Engineered for compact PCB layouts, high-density signaling, and automated SMT assembly, our electronic connector systems cover 0.50mm to 2.54mm pitch board-to-board, wire-to-board, wire-to-wire, and FPC configurations. Utilizing high-temperature Liquid Crystal Polymer (LCP) or PA9T thermoplastics and automated pin-coplanarity inspection, these interconnects deliver low contact resistance and solder heat resistance up to 260 deg C peak reflow temperatures.

Materials & Mechanical Structures
 

 

Insulator Housings

High-temperature Thermoplastics (LCP, PA9T, PA6T, PBT) with UL 94V-0 flame ratings. Material choice eliminates plastic blister risks during lead-free reflow profile cycles up to 260 deg C.

Contact Terminals

Precision-stamped Phosphor Bronze (for spring resilience and fatigue resistance) or Brass (for standard headers).

Plating Specifications

Matte Tin (100 u-inch min) over Nickel underplate for standard solderability; Gold flash or Selective Gold plating (1 u-inch to 30 u-inch) on contact touchpoints to prevent contact oxidation and fretting wear across 50+ mating cycles.

SMT Mechanical Anchors

Optional board locks, metal solder tabs, and post alignment pegs to provide PCB shear strain relief during manual cable plugging.

 

OEM/ODM & Drop-in Replacement Services

OEM/ODM & Drop-in Replacement Services

Cross-compatibles matched pin-for-pin to major industry part numbers (Molex Picoblade / Micro-Fit, JST SH / PH / XH, Samtec FTSH / SSW series), requiring zero layout changes on customer PCBs.

Custom Molding & Pin Heights

Custom header insulator heights, pin lengths, selective pin loading (voided pins for creepage distances), and keying options. [ Note: Max pin count capability per row subject to custom mold limits - Please verify with Engineering ].

Packaging Formats

Automated pick-and-place compatible Tape & Reel packaging with pick-caps or vacuum tape film, as well as Tube and PE bag options.

FAQ

 

Q: What insulator materials are used to ensure connectors withstand lead-free reflow soldering without blistering?

A: We utilize high-temperature LCP (Liquid Crystal Polymer) or PA9T resin for all SMT and THR connector housings. These materials maintain structural rigidity and dimensional tolerance during 260 deg C peak lead-free reflow temperature profiles.

Q: How do you verify pin coplanarity for High-Density SMT headers before shipping?

A: Every SMT header reel passes through automated 3D CCD optical inspection systems on the packing line. Any pin exhibiting coplanarity exceeding 0.10mm (or 0.08mm for fine-pitch FPC series) is automatically rejected.

Q: Can your connectors directly replace brand-name parts without modifying our existing PCB Gerber layout?

A: Yes. Our cross-reference series match the exact mounting footprints, solder pad dimensions, pin pitches, and mechanical heights of standard series from Molex, JST, Hirose, and Samtec.

Q: What selective plating options are available for low-voltage signal applications?

A: We offer selective gold plating ranging from Gold Flash (1 u-inch) up to 30 u-inch Gold over 50 u-inch Nickel on contact mating surfaces, paired with matte tin on soldering tails to optimize signal transmission while controlling cost.

Q: What is the standard packaging format for automated SMT assembly lines?

A: SMT connectors are packaged in EIA-481 compliant Tape & Reel reels equipped with pick-and-place suction caps or tape strips, enabling direct compatibility with high-speed feeder systems.

Q: What compliance documentation is provided for regulatory audits?

A: Every product family includes downloadable material declaration sheets, RoHS 2.0 compliance certificates, REACH SVHC declarations, UL safety certificates [ Technical Verification Required: Insert UL File Number, e.g., E123456 ], and batch-specific inspection reports (COA).
