Quality Control & Audit Readiness
Audit Readiness & Quality Control Process
Every KOSEN SEMI certification reflects an active, rigorously enforced quality management system. Learn more about us and how our end-to-end traceability standards and continuous audit readiness protocols ensure every production lot is backed by verifiable documentation, giving global procurement teams complete confidence during supplier evaluations.
Sustaining ISO 9001, ISO 14001, and IATf 16949 compliance goes far beyond passing annual third-party audits. It requires a disciplined, process-driven quality management system that monitors parameters at every manufacturing stage, verifies material compliance with RoHS Directive and REACH SVHC requirements, and locks down complete documentation before components ship.
The four-stage framework below details how KOSEN SEMI maintains continuous audit readiness across raw material entry, in-process manufacturing, final testing, and documentation archiving—providing QA directors and procurement managers with absolute visibility into product lot lineage.
Every batch of raw materials undergoes multi-point compliance testing before entering production. Dimensional, chemical, and electrical characteristics are validated against approved technical specifications and strict ISO 9001 incoming quality assurance criteria.
To ensure full RoHS REACH compliance, materials undergo X-ray fluorescence (XRF) spectroscopy and independent laboratory testing to verify strict adherence to hazardous substance concentration thresholds for lead, cadmium, mercury, and hexavalent chromium under RoHS 2011/65/EU and REACH candidate lists.
- Approved vendor list (AVL) verification is performed for every incoming material batch.
- Non-conforming material quarantine prevents unverified stock from entering active manufacturing lines.
- RoHS/REACH substance screening data is digitally archived and mapped directly to production lot numbers.
Manufacturing workflows inside our state-of-the-art manufacturing facility are governed by detailed control plans grounded in ISO 9001 process standards and IATF 16949 Advanced Product Quality Planning (APQP) frameworks. High-precision production lines leverage Statistical Process Control (SPC) to monitor tolerance drift in real time.
Automated optical inspection (AOI), solder paste inspection (SPI), thermal profiling, and key tooling parameters generate real-time digital logs for every production run. This data is instantly indexed for engineering oversight and stored in alignment with global automotive and industrial retention standards.
- Version-controlled work instructions ensure strict process consistency across all manufacturing shifts.
- Automated non-conformance containment immediately isolates out-of-spec production variables.
- Certified operator tracking ensures compliance with IATF 16949 competency matrix guidelines.
Before release, 100% of finished products undergo automated electrical testing, parameter qualification, and visual inspection. Acceptance criteria are strictly aligned with customer-approved control plans and international IPC/IEEE standards.
For high-reliability automotive and industrial applications, secondary sampling verification is performed by accredited third-party testing laboratories. This dual-layer validation provides unbiased proof of conformance, streamlining supplier quality audits and incoming inspection at customer facilities.
- Serialized test logs connect final inspection data to specific component reels and lots.
- Accredited laboratory reports provide independent verification for critical customer applications.
- Defect-reduction targets drive ongoing root-cause analysis and preventive action initiatives.
Every outbound shipment is issued an official Certificate of Conformance (CoC) alongside comprehensive batch test reports. The CoC certifies that delivered products meet all agreed customer specifications, industry standards, and environmental regulatory mandates.
All compliance assets—including CoC records, material test reports, RoHS/REACH declarations, and inspection certificates—are stored in an enterprise document management system. Full lot traceability records can be retrieved within 24 hours to support customer compliance reviews, audits, or technical inquiries.
- Comprehensive CoC documentation includes lot numbers, test metrics, standards compliance, and QA sign-offs.
- Rapid 24-hour audit response guarantees fast delivery of complete lot traceability packages.
- Secure digital document archive facilitates effortless remote auditing for global procurement teams.
