Project-specific quality control

QUALITY PROCESS

Quality is a controlled workflow.

From requirement review to shipment release, inspection is tied to the approved model, configuration, target market, agreed approval evidence and project quality plan. Sample availability is confirmed by model; S18D is bulk-only with no evaluation samples.

01 / REFERENCEApproved specificationThe confirmed configuration and commercial documents form the control baseline.
02 / VALIDATIONSample approvalAppearance, function, accessories and packaging are reviewed before production.
03 / TRACEABILITYInspection recordsChecks and project documents are organised around the relevant order and model.
04 / RELEASEDefined acceptanceShipment follows the agreed sampling method, criteria and release decision.

PRODUCTION PROCESS

Eleven stages, from R&D to shipment.

The sequence below is a production-workflow reference. Applicable stages, responsibilities, test scope and records depend on the model and order. A stock order does not repeat a new development and production cycle; confirm what verification and release evidence apply to the goods supplied.

01R&DPlatform selection, feasibility review and the specification the programme will be built to.
02MaterialsComponent and material sourcing against the approved bill of materials.
03InspectionIncoming material inspection - the first gate, before any component reaches the line.
04AssemblySub-assembly and final assembly of the unit.
05LQCLine quality control, carried out during assembly rather than after it.
06Burn-in RackThe agreed stability or aging procedure is applied where required by the model and project quality plan; duration, load and acceptance criteria are confirmed separately.
07FQCFinal quality control - function, configuration and appearance verified before packing.
08Software WritingOperating system image, drivers and the agreed software set written and verified.
09OQCOutgoing quality control - a sampling check on finished, packed goods before release.
10PackagingRetail or bulk packaging, artwork and shipping marks to the approved artwork.
11Shipment & TransportationDocuments, compliance set and despatch from the factory.

Where surface-mount assembly fits: the surface-mount stage inside steps 02 to 04 is itself a multi-stage sub-process - incoming material inspection, the placement line, appearance check and functional testing. Aging duration, test scope and sampling method are confirmed per project rather than assumed.

SIX CONTROL GATES

Control begins before production.

A final inspection cannot correct an unclear specification. Our process starts by defining what will be built, how it will be checked and what evidence the project requires.

01

Requirement review

Confirm model, configuration, target market, accessories, artwork, packaging, test items, sampling approach and required documents.

02

Incoming material inspection

Review relevant materials and components against the approved project reference before they enter the production process.

03

Assembly & functional testing

Carry out defined checks during assembly and verify essential device functions for the approved configuration.

04

Burn-in / aging test

Run the agreed stability or aging procedure where applicable to the model and project quality plan.

05

Outgoing quality control

Check sampled finished units for appearance, function, configuration, accessories, labels and packaging before release.

06

Shipment release

Close identified issues, complete the agreed records and release goods according to the confirmed acceptance requirements.

PROJECT EVIDENCE

The proof should match the exact product.

Specifications, samples, reports and inspection records are useful only when they correspond to the supplied model, configuration and destination.

01 / SPECIFICATION

Configuration reference

Processor, memory, storage, display, wireless, ports, battery, accessories and software scope.

02 / SAMPLE

Approval reference

Appearance, structure, functionality, branding, packaging and agreed deviations.

03 / INSPECTION

Quality records

Project-defined checkpoints, findings, corrective action and release status where agreed.

04 / COMPLIANCE

Applicable documents

Relevant reports or certificates reviewed against the specific model and target market.

DOCUMENTATION & COMPLIANCE

Documents matched to your model and market.

Available documentation depends on the exact platform and destination. It may include CE, RED, FCC, DoC, EAA, RoHS, UN38.3 and MSDS. We confirm the applicable documents for your configuration and target market before order confirmation.

Confirm the scope: a document for one model, battery or configuration does not automatically cover another. The agreed document set is listed with the project requirements.
CEPlatform conformity documentation, where applicable.
REDRadio equipment documentation, where applicable.
FCCAvailable documentation for US market review.
DoCDeclaration of conformity for the applicable product.
EAAAccessibility documentation where available and applicable.
RoHSMaterials-related compliance documentation.
UN38.3Battery test documentation for the relevant battery pack.
MSDSBattery handling and safety information.

QUALITY FAQ

Quality and certification questions.

Short answers to the questions buyers ask most often before an order is placed.

What compliance documentation is available?

Available documentation depends on the exact platform and destination. It may include CE, RED, FCC, DoC, EAA, RoHS, UN38.3 and MSDS. We confirm the applicable documents for your configuration and target market before order confirmation.

How do we confirm which certifications apply to our order?

Send the destination market and the exact configuration. We review the requirement against the specific product, confirm the applicable documents during quotation, and list the agreed compliance deliverables in the approved commercial documents. A certificate covering one model or configuration is not automatically valid for another.

How is quality controlled during production?

At defined gates rather than at the end: incoming material inspection before components reach the line, line quality control during assembly, burn-in on the aging rack, final quality control before packing, and outgoing sampling before release. Test scope, sampling method and acceptance criteria are agreed with the project.

What is the difference between LQC, FQC and OQC?

LQC is line quality control and runs during assembly, so a fault is caught on the line rather than after the unit is finished. FQC is final quality control and checks function, configuration and appearance before the unit is packed. OQC is outgoing quality control and samples finished, packed goods before shipment is released.

Do you carry out aging or burn-in testing?

An aging or stability procedure can form part of the project quality plan. Confirm the exact model, test scope, workload, duration, power and environmental conditions, acceptance criteria and records before approval. This page does not establish a universal test duration or 100% test scope for every order.

What documentation ships with an order?

Confirm the packing list, accessories, adapter and plug, manual language, labels, inspection evidence and applicable product and battery documents for the ordered build. Inclusion, translation, branding and any extra preparation are stated in the quotation. S18D supplied adapter, charging power, cable and plug remain to be confirmed.

Can we evaluate the quality before placing a production order?

Selected available standard configurations may be quoted from one unit for evaluation. Confirm the exact model, configuration, sample price, preparation and dispatch before payment. S18D is bulk-only with no evaluation samples; agree the bulk-order approval evidence, and do not treat a different model’s sample as its approval.

Does an inspection stage mean every unit receives the same tests?

No universal sample size, test duration or acceptance threshold is established by the stage name. Confirm the inspection method, unit coverage, test conditions, pass/fail criteria, handling of findings and required release evidence in the project quality plan.

APPROVAL RECORDS

Five decisions to record in the quality plan.

Agree these before inspection. A named process stage is not evidence of a particular test duration, sample size or acceptance threshold.

01

Control reference

Exact model and build, specification revision, artwork, supplied power, accessories and the sample or agreed approval evidence. Mark unresolved items before release.

02

Inspection method and quantity

Batch size, which checks cover which units, any sampling method, sample size and the person responsible. Do not infer a 100% inspection from the existence of an OQC stage.

03

Test conditions and acceptance

Test item, procedure, workload, duration, relevant conditions, permitted variation and pass/fail criteria. Record cosmetic and functional requirements separately.

04

Nonconformity and retest

How findings are identified, contained and corrected; who approves any deviation and what must be retested before goods can be released.

05

Release evidence

Agreed inspection results, photos or records, batch identifiers, open-item closure, release approver and any buyer review required before collection.

Use the specification status guide, batch-release checklist and battery-document review to keep the build, inspection and shipping records aligned.
