I. Solidify Technical Foundations: Core Processes & Advanced Equipment

1. Mastery of Core Processes

• Key Process Expertise: We excel in three core areas—circuit formation (lithography + etching), interlayer interconnection (lamination + via metallization), and flexibility assurance (material selection + bending life optimization). Our FPCs achieve standard line width/spacing ≤20μm (precision down to 10μm), interlayer alignment accuracy within ±3μm, and bending life ≥1 million cycles for dynamic applications (e.g., foldable devices).
• Versatile Process Adaptability: Seamlessly switch between single-sided/double-sided/multi-layer FPCs (up to 20 layers), adhesive-free/adhesive-based structures, and rigid-flex PCBs to meet diverse flexibility and density requirements.

2. Advanced Equipment Investment

• Circuit Formation: LDI laser direct imaging machines (alignment accuracy ±2μm), acid etching lines with side-etch control;
• Interlayer Processing: Vacuum laminators (vacuum degree ≤10Pa), UV laser drilling machines (hole diameter ≥50μm, hole position accuracy ±5μm);
• Inspection Equipment: AOI (Automated Optical Inspection) systems (resolution ≥10μm), 100% coverage flying probe testers, X-ray interlayer inspectors, and bending life test machines.

3. Rigorous Material Management

• Qualified Supplier Network: Core materials (PI/PET substrates, roll-annealed/electrolytic copper foil, adhesives) are sourced exclusively from global renowned brands such as DuPont, Toray, and Nan Ya. 100% incoming inspection (thickness tolerance, temperature resistance, adhesion) ensures zero material defects.
• Scenario-Based Material Matching: Recommend optimal material combinations—e.g., "modified PI + RACu + adhesive-free structure" for foldable screens, and "PET + electrolytic copper + adhesive-based structure" for cost-sensitive applications—balancing performance and budget.

II. Establish Quality Systems: End-to-End Control & Certified Compliance

1. Standardized QMS Implementation

• Incoming Quality Control (IQC): Comprehensive inspection of substrates, copper foil, and auxiliary materials; unqualified materials are rejected outright.
• In-Process Quality Control (IPQC): First-article inspection + regular audits at critical processes (lithography, etching, lamination, drilling), with real-time recording of process parameters (temperature, pressure, time) to prevent batch defects.
• Final Quality Control (FQC): 100% electrical testing (continuity/insulation/impedance), 100% visual inspection (AOI + manual review), and random reliability testing (temperature cycling, humidity testing, bending tests).
• Full-Traceability System: Unique batch codes track raw material batches, production equipment, operators, and test data for rapid issue localization.

2. Authoritative Certifications

• General Certifications: ISO9001 (Quality Management System), ISO14001 (Environmental Management System);
• Industry-Specific Certifications: IATF16949 (automotive electronics), ISO13485 (medical devices);

• Environmental Compliance: RoHS, REACH-compliant products with halogen-free materials and low-VOC processes.
  

III. Ensure Production Capacity & Delivery: Flexible Adaptation & Rapid Response

1. Flexible Production Line Design

• Modular Production Lines: Swiftly switch between small-batch customization (≤1000 units) and mass production (≥100,000 units), eliminating the pain point of "unable to handle large orders or unwilling to accept small ones."
• Capacity Redundancy: 20%-30% reserved capacity to address urgent orders and peak demand.

2. Efficient Delivery Cycle

• Prototype Lead Time: 3-5 days for standard single/double-sided FPCs, 5-7 days for multi-layer FPCs—accelerating customers’ R&D cycles.
• Mass Production Lead Time: 15-25 days for batches ≥10,000 units (including scheduling, production, inspection, and packaging).
• Supply Chain Synergy: Emergency supply agreements with core material suppliers and safety stock reserves prevent delivery delays due to material shortages.

IV. Strengthen Customized Services: From "Order Fulfillment" to "Solution Partner"

1. Pre-Sales Technical Support

• DFM Engineering Team: Offer free FPC design optimization (wiring rationality, stackup structure, bending area reinforcement) to avoid "production difficulties or product failure caused by poor design." Provide detailed DFM (Design for Manufacturability) reports specifying minimum line width, hole diameter, pad size, and other manufacturability parameters.

2. Flexible Customization Capabilities

• Parameter Customization: Tailor line width/spacing, layers, thickness, surface finishes (ENIG/tin plating/OSP), and forming shapes (special-shaped cutting) to customer requirements.
• Scenario-Specific Customization: Develop specialized FPCs for high-temperature (≥150℃), high-flexibility (1 million bending cycles), and biocompatible (medical) applications, with complete reliability test reports (salt spray, humidity, bending life, etc.).

3. Rapid After-Sales Response

• Dedicated After-Sales Team: 24-hour response and 48-hour solution provision for customer inquiries (e.g., performance issues, delivery delays).
• Defect Handling: Unconditional replacement/refund for production-related defects, with corrective action reports to prevent recurrence.

V. Compliance & Sustainable Development: Uphold Principles & Long-Term Growth

1. Compliant Operations

• Intellectual Property Protection: Strictly safeguard customer design drawings and patents, adhering to business integrity.
• Environmental Responsibility: Adopt halogen-free materials and low-VOC processes; ensure wastewater and waste gas meet emission standards in line with global environmental policies.

2. Continuous R&D Investment

• Process Optimization: Pursue 5μm/5μm precision wiring and cost reduction.
• New Material Application: Test advanced PI substrates and eco-friendly adhesives to enhance bending life and temperature resistance.
• Scenario Expansion: Develop high-reliability FPCs for autonomous driving, wearable medical devices, and aerospace applications.

VI. Build Professional Teams: Talent as Core Competitiveness

1. Key Role Configuration

• Process Engineers: Proficient in full FPC production processes, resolving technical issues such as uneven etching, interlayer bubbles, and via conduction failures.
• Quality Engineers: Deeply familiar with IPC standards, designing custom inspection plans for accurate product qualification assessment.
• Sales Engineers: Combine technical expertise and market insight to accurately translate customer needs and coordinate internal resources for seamless collaboration.

2. Comprehensive Training System
