Consistency managed by systems, proven by data.

Sanjin’s quality management approach combines certified systems, process control, inspection data, and in-house reliability validation for high-reliability semiconductor packaging components.

Certified systems for controlled manufacturing.

Sanjin’s operating framework is built around internationally recognized management systems that support defect prevention, process consistency, environmental responsibility, and continuous improvement.

IATF 16949

Automotive quality management system focused on defect prevention, variation reduction, and supply-chain discipline.

ISO 9001

Quality management system supporting consistent product realization, documented processes, and continual improvement.

ISO 14001

Environmental management system guiding responsible operations, compliance, and resource-conscious manufacturing.

Quality control begins before production.

Sanjin’s quality work starts with material protection, controlled production conditions, drawing management, and process planning before parts move through manufacturing.

Material, environment, and drawing control

Sensitive raw materials and protected finished parts can be stored in nitrogen cabinets when required. Temperature and humidity are monitored for relevant processes, while customer drawings, R&D files, orders, and production records are managed through controlled internal systems.

In-process inspection

Inspection is built across the manufacturing flow, from incoming materials to stamping, plating, assembly, and final release. Typical controls include burrs, warpage, surface condition, plating thickness, dimensions, coplanarity, and hermetic performance depending on product type.

Automated inspection and traceability

AOI is applied across product lines, while CCD inspection supports high-volume production where continuous visual and dimensional monitoring is required. Each production lot is traceable through Sanjin’s internal ERP system.

Validation record

Validation matched to product risk.

Different components fail in different ways. Sanjin selects inspection and reliability methods around the actual risks of the product, material, and application.

Risk focus Validation methods

Metal components

Burrs, warpage, plating thickness, surface condition, dimensions, and coplanarity.

AOI, CCD inspection, high-resolution projection, X-ray spectrometry, and dimensional verification.

Hermetic packages & GTMS

Leak performance, thermal stability, material compatibility, and expansion matching.

Helium leak detection, thermal shock cycling, X-ray analysis, projection measurement, and reliability checks.

Plastic packages & material programs

Thermal dissipation, shrinkage behavior, mechanical stability, and process consistency.

Material validation, thermal cycling, dimensional inspection, AOI/CCD monitoring, and process data review.

When issues happen, the process improves.

Customer feedback and nonconformities are reviewed through structured internal meetings. When required, Sanjin follows 8D corrective-action methods so lessons are fed back into process control, inspection planning, and production standards.

Identify

Customer feedback, inspection data, or production abnormalities are recorded and brought into the quality review process.

Review

Quality, engineering, and production teams review root cause, containment actions, and the process conditions behind the issue.

Improve

Corrective actions are fed back into process control, inspection planning, operator standards, and future production requirements.
