Quality management system

IQC, IPQC, OQC and traceability — ISO 9001 quality process for every batch.

Four lines of quality defense

Inspection scope and record requirements for each stage are in the detail panels below.

  • Incoming IQC

    Electronic components, mechanical parts and packaging sampled or fully inspected per spec; nonconforming material quarantined with supplier feedback.

  • In-process IPQC

    Patrol points at SMT, soldering, assembly and test stations; deviations trigger immediate line stop and correction to prevent defect propagation.

  • Outgoing OQC

    Before shipment verify model, appearance, function, accessories and labels; AQL sampling with inspection records retained.

  • After-sales traceability

    Link production batches, firmware versions and service tickets to root cause and drive corrective and preventive action (CAPA).

Incoming IQC

Critical electronics, relays, plastics and packaging sampled or fully inspected per enterprise standard with incoming batch records. Nonconforming material quarantined and supplier corrective action triggered to avoid line introduction.

How the system is implemented

Documented quality management system and internal audit meeting

Documented, auditable, improvable

Quality manual, procedures and work instructions cover design, purchasing, production, inspection and after-sales. Internal audits and management reviews regularly assess effectiveness — ensuring what is written matches what is done on the floor.

  • Design and BOM changes reviewed and engineering docs synced
  • Inspection specs and enterprise standards iterate with product versions
  • Customer complaints in quality meetings and satisfaction tracking
Automated test laboratory

Engineering-oriented quality metrics

We track not only outgoing yield but first-pass commissioning rate and in-warranty failure rate. Quality data feeds R&D and process teams to optimize connector selection, thermal design and firmware strategy.

  • Typical failure mode library and rework analysis reports
  • Known issue lists and avoidance guidance shared with integrators
  • Spares same process and inspection as mass production

Certifications & credentials

Selected certificates shown below; see the dedicated page for the full list.

Outgoing inspection record sample

Redacted sample showing OQC record structure and traceability fields; PDF samples available for bulk projects on request.

Outgoing inspection record sample
Redacted sample · not a formal release document

What fields are included?

Formal outgoing inspection records link production batch, order number, inspector and approval signatures — forming a trace chain with IQC / IPQC in-process records.

  • Product model, batch number, inspection date and sampling plan
  • Appearance, power-on self-test, relay/comm, accessory list verdicts
  • Inspection conclusion and release signature (samples available per project)

Batch traceability

Production batch traceability and ledger management

From batch number to service ticket

Outgoing labels, packing lists and production ledgers use unified batch coding. After-sales issues trace back to incoming batches, process stations and firmware versions — supporting 8D reports and CAPA closure.

  • Batch numbers through IQC → in-process → OQC → logistics
  • Linked to R&D document versions and firmware release notes
  • Major incidents communicated to integrator partners

8D corrective & preventive process

For major batch incidents or customer complaints, quality leads cross-functional 8D closure — mapped to the five CAPA steps below; reports available to integrators for owner filing.

Nonconformance & corrective process

Switch steps to view CAPA closure highlights at each stage.

  1. Identify & isolate

    Incoming, in-process or complaint trigger; nonconforming material tagged and isolated; related batches held.

  2. Root cause analysis

    Engineering, quality and production joint review; separate design, process, material and operation factors.

  3. Corrective action

    Short-term containment and long-term countermeasures in parallel; update SOP or design docs.

  4. Verify & close

    Post-action sampling verification; record closure and add to lessons learned.

  5. Preventive rollout

    Alert similar models and suppliers; issue technical notices when needed.

Quality points owners often ask about

  • Bid technical chapters can cite ISO system and product certification scans (see Honors page)
  • Bulk deliveries can include outgoing inspection record samples and batch traceability statements
  • Transparent warranty and after-sales; spare parts match mass-production quality
  • Major quality issues trigger 8D reports with integrator support for owner briefings
