Electrical Wiring Interconnection Systems

Advanced Electrical Architecture Design

EtoE Interconnections specializes in the design and development of advanced Electrical Wiring Interconnection Systems (EWIS) for mission-critical platforms. Our engineers leverage digital twin modeling and advanced simulation tools to create efficient, lightweight, and high-performance electrical architectures. Each design is optimized for safety, functionality, and serviceability while meeting strict industry and defense standards. The result is a robust system architecture that delivers superior reliability across diverse applications.

Precision and Compliance

Every EWIS solution is engineered with precision, EMI shielding, and optimized weight-to-performance ratios. We ensure full compliance with international aerospace and defense standards, including AS9100D, MIL-STD, and JSS 55555 specifications. Whether it’s a build-to-print or print-to-build project, our process emphasizes traceability, verification, and quality assurance at every stage. This commitment to precision guarantees reliability and long-term performance in even the most demanding environments.

Applications Across Industries

Our EWIS solutions power a broad spectrum of industries, including aerospace, defense, UAVs, and industrial automation. Designed for critical power and signal distribution, these systems provide robust connectivity and operational safety in complex environments. From aircraft platforms to automated production systems, our interconnections ensure uninterrupted performance, minimal maintenance, and extended service life across all mission-critical applications.

A Streamlined Process Built for Reliability, Safety, and Performance

Step 01

Requirements Analysis & Engineering Support

We collaborate with clients to review technical documents, schematics, and interface requirements. Our team ensures manufacturability, compliance, and optimized harness routing. We provide engineering support that enhances build efficiency without modifying the original design.

Step 02

Prototyping & Validation

Our team develops prototype harnesses and assemblies, performing mechanical, electrical, and environmental validation to guarantee performance and reliability in mission-critical conditions.

Step 03

Manufacturing & Assembly

Through automated wire processing, robotic assembly, and precision crimping, we produce EWIS systems built to the highest quality standards. Every assembly undergoes IPC-certified inspection and documentation for full traceability.

Step 04

Testing & Quality Assurance

Before deployment, all systems undergo rigorous testing—including continuity, vibration, and EMI/EMC per MIL-STD and RTCA DO-160 standards. We also offer installation support, maintenance, and product lifecycle management to ensure sustained performance.
