In quality control in assembly services, robust quality assurance isn’t just a requirement—it’s the cornerstone of competitive, contract manufacturing. Smartlink Engineering, with its ISO 9001:2015 and AS9100-certified processes, consistently delivers precise, defect-free assemblies. Here’s how they ensure quality excellence at every step.
1. Rigorous Quality Management System
Smartlink operates a certified Quality Management System (ISO 9001 and AS9100) across both Shah Alam and Penang plants, demonstrating adherence to global best practices in defect prevention, risk control, and compliance.
- Documented procedures & traceability: Every part and process is tracked—materials, inspections, and tests—ensuring full lineage .
- Skilled, certified teams: Named workspaces are staffed by operators trained to IPC-620 standards for cable & harness assembly.
- Continuous improvement: As an ISB-certified advisor, Smartlink also integrates ESG-driven practices to enhance quality and sustainability.
2. Multi-Layered Inspection & Testing
Quality assurance begins with incoming materials and runs through final delivery:
- Incoming inspection: All components undergo pre-assembly validation.
- In-process checks: Ongoing quality control during assembly, including functional tests and visual inspections.
- Final testing protocols: Includes in-circuit checks, functional testing, continuity and pull tests, especially for cable harnesses.
This tiered approach aligns with best practices outlined in ISO/AS standards.
3. Precision Toolshop & Metrology
Smartlink’s on-site toolshop enables meticulous part manufacturing and immediate correction:
- High-precision CNC machining: Achieves ±0.005 mm tolerances, backed by calibrated measurement tools.
- State-of-the-art metrology equipment: Features digital calipers, micrometers, granite tables, and plug gauges to maintain component integrity .
- Process verification: Routine calibration and control of measurement systems ensure consistent accuracy.
4. Clean & Controlled Production Environments
Maintaining product integrity requires the right environment:
- ISO6 certified cleanrooms: Smooth, dust-reduced surfaces support contamination-sensitive assembly.
- ESD compliance: Ensures safe handling of sensitive electronics during cable and module assembly.
5. Standardized Process Controls
Smartlink enforces strict process discipline using ISO/AS-aligned methods:
- Work instructions & control plans guide every step.
- First article inspection (FAI) ensures prototype integrity before production ramp-up.
- Corrective/preventive actions: Root-cause analysis tools like 8D are used to stop defects at the source.
- Inspection status monitoring: Products are clearly labeled to indicate approved, in-process, or rejected parts.
6. Traceability & Compliance Documentation
Traceability isn’t optional; it’s mandatory:
- Lot-to-lot traceability with documents retained as part of compliance audits.
- Compliance-ready reporting: Smartlink supports audits with documentation aligned with ISO and aerospace standards.
- RoHS, UL, Class 3 work: Available upon request to meet specific industry standards.
7. Strategic Facility Setup
Smartlink’s two-pronged facility structure enhances control:
| Location | Highlights |
| Shah Alam HQ | 35,000 sq ft total built up area; separate cleanrooms; laser automation, toolshop and harnessing areas with certified workforce |
| Penang branch + expansion
China |
Total Built-up Area: 45,000 sq ft of production space; ideal for high-mix, low-volume builds; IPC620-trained team
30,000 sq ft of built up area |
Their setup includes dedicated toolshops and QA zones at both sites for consistent quality across all builds.
