2. Core Competitive Advantages

2.1 Comprehensive Quality Management & Traceability

TDT’s quality-first philosophy is anchored by globally recognized certifications:

IATF16949: Automotive-grade defect prevention and process stability.

ISO13485: Full lifecycle traceability for medical devices.

QC080000: RoHS/REACH compliance for eco-friendly industrial/consumer products.

ISO9001:2015: Cross-industry quality assurance with PDCA efficiency cycles.

Smart Quality Control Tools:

ERP-MES Integration: Real-time tracking from procurement to delivery.

Closed-Loop Traceability: Post-sales data analysis for warranty claims and failure diagnostics.

Material FIFO Management: Minimizes obsolescence risks.

2.2 Smart Production Ecosystem

Our digital transformation strategy leverages ERP and MES systems to eliminate silos and optimize workflows:

Example 1: Material Traceability

Every component is logged with batch numbers, expiry dates, and supplier details, enabling rapid root-cause analysis.

Example 2: Intelligent Warehouse

Automated alerts for component shortages, humidity/temperature deviations, and reorder triggers.

Example 3: Process Error Prevention

AI-powered AOI (Automated Optical Inspection) and X-ray systems detect defects at early stages, reducing rework costs.

2.3 State-of-the-Art Engineering Capabilities

PCB Fabrication

SMT Assembly

Mounting Accuracy: ±25μm (3σ) with Cpk≥1.33.

Components: Handles 01005 packages, 0.3mm-pitch ICs, and 74mm x 74mm BGAs.

Inspection: SPI, AOI, X-ray, and functional testing.

2.4 End-to-End Process Integration

Since 2016, our subsidiaries have streamlined the PCBA value chain:

BOM Optimization: Alternative component recommendations to slash procurement costs.

Component Sourcing: Partnerships with TI, ST, Murata, etc., backed by FAE technical support.

Full Turnkey Services:

SMT → DIP Soldering → Conformal Coating → Functional Testing → Final Assembly.

3. Case Studies: Delivering Measurable Value

Case 1: Automotive Client Cost Reduction

A European automotive supplier faced rising component costs for an ECU (Engine Control Unit). TDT’s FAE team proposed alternative ICs and passives, achieving a 22% BOM cost reduction without compromising performance.

Case 2: Medical Device Traceability Compliance

For a US-based MRI equipment manufacturer, TDT implemented a blockchain-enabled traceability system, reducing compliance audit time by 40%.

4. Financial Stability & Growth

TDT’s revenue growth reflects our reliability:

2021: $35.86M

2022: $35.96M

2023: $36.28M (projected)

Our consistent performance ensures long-term partnerships and risk-free scalability for clients.
