Automotive-Grade Electronic Components Manufacturing

IATF 16949 certification demonstrates our commitment to automotive quality management standards. The standard builds on ISO 9001 and adds the discipline the automotive supply chain runs on: a part is not just made to print, it is planned, proven, and monitored. That means the process is designed up front (APQP), failure modes are analyzed and designed out before tooling (FMEA), the finished process is formally proven and submitted for sign-off (PPAP), and critical characteristics are watched in production with statistical process control. The result is a part that is traceable from the raw coil to the shipped lot, which is what lets a Tier-1 or OEM accept it into a safety-relevant system.

Key aspects of our IATF compliance:

• Advanced Product Quality Planning (APQP)
• Production Part Approval Process (PPAP)
• Failure Mode and Effects Analysis (FMEA)
• Statistical Process Control (SPC)
• Full traceability from raw material to finished part

Modern vehicles contain dozens of electronic control units (ECUs) sharing a harness and a battery rail, so one module's noise is every other module's immunity problem. The dominant aggressor is switching power conversion: every DC-DC converter and motor driver produces broadband harmonics that ring well into the hundreds of MHz. Component-level EMC is qualified against CISPR 25 (roughly 150 kHz to 2.5 GHz, conducted and radiated), and a shield only delivers across that band if its grounding stays continuous — at the GHz end of CISPR 25 the λ/20 aperture rule pushes lid-finger and via spacing down to a few millimeters. Board-level shields, grounding clips, and spring contacts are the parts that hold that continuity in a vibrating, thermally cycled environment.

Common automotive EMI applications:

• Powertrain control modules
• ADAS and sensor systems
• Infotainment and connectivity modules
• Battery management systems (EV/HEV)
• Body control and lighting systems

Automotive components must perform reliably across wide temperature ranges, vibration environments, and multi-year operational lifespans — typically 15 years and 150,000+ miles. For stamped EMI and contact parts, the failure modes that matter are mechanical and electrochemical rather than catastrophic: a grounding spring that relaxes and loses normal force at +125 °C, a contact interface that develops fretting corrosion under vibration and rising resistance, or a plating choice that corrodes under thermal-humidity cycling. Our design and manufacturing processes account for these by controlling spring temper, contact normal force, and surface finish, and by validating against the environments below rather than nominal room conditions.

Reliability considerations include:

• Temperature cycling validation (-40°C to +125°C typical)
• Vibration and shock resistance per automotive standards
• Corrosion resistance and environmental sealing
• Long-term material stability and contact resistance
• Compliance with OEM-specific reliability requirements

We work directly with automotive OEMs and Tier-1 suppliers to support product development, qualification, and transition to production. In practice that means engaging at the design-in stage with DFM and tolerance review, building the APQP and control-plan documentation as the tool is developed, and delivering the PPAP package at the submission level the customer requires before the part is approved for production. Our San Diego team coordinates with our Korea R&D and manufacturing group to keep this aligned with the customer's program timing.

Collaboration includes:

• Joint design reviews and DFM consultation
• Prototype and validation sample support
• PPAP documentation and submission
• Production ramp and capacity planning
• Ongoing quality and continuous improvement
