INCOMING MATERIAL INSPECTION

Quality Starts Before Assembly

Before materials enter production, key components are checked against approved specifications, samples and purchase requirements.

We inspect critical incoming materials to identify obvious defects, specification mismatches and batch inconsistencies before they reach the assembly line.

INCOMING MATERIAL INSPECTION

Preventing Material Issues Before Production Begins

Every stable production batch starts with controlled incoming materials.

Before components are released to production, our quality team checks incoming parts against approved specifications, reference samples and purchase requirements.

Typical incoming materials for TENS and EMS products include PCBs, batteries, electrode pads, lead wires, plastic housings, display components, heating elements, connectors and packaging materials.

 

Inspection focuses on the characteristics that can directly affect assembly, function and finished-product consistency.

Depending on the material type, checks may include appearance, dimensions, identification, electrical characteristics, fitting condition and basic functional verification.

Non-conforming Material Control

Materials that do not meet the required specification are identified and separated before production use. Inspection records also help support batch traceability and later root-cause investigation.

FAQs

What materials are checked before production?

Key incoming materials may include PCBs, batteries, electrode pads, lead wires, housings, displays, connectors, heating components and packaging materials, depending on the product configuration.

Are custom components checked against approved samples?

Yes. For customized projects, incoming components can be checked against confirmed specifications, approved samples or agreed product requirements before they are released to production.

What happens if incoming materials fail inspection?

Non-conforming materials are identified and separated from approved production materials for further evaluation, supplier feedback or replacement according to the actual issue.

Can incoming material batches be traced?

Inspection and material information can be recorded by batch to support production traceability and later quality investigation when required.

Specification Verification

Incoming components are checked against approved specifications, reference samples or purchasing requirements before production use.

Critical Component Verification

Key electrical or functional characteristics are checked when required for materials such as PCBs, batteries, heating components and electrode accessories.

Appearance & Dimension Check

Housing parts, connectors, wires, pads and other materials are checked for visible defects, dimensions, fitting condition and workmanship.

Batch Identification & Traceability

Material batches and inspection results can be recorded to support production control, issue tracking and quality investigation.
