Incoming Quality
Verify approved parts, supplier lots, revisions and critical materials before release to production.
IQC · AVL · TraceabilityQuality by design · Quality at every stage
Built for Quality.
Proven by Process.
Designed into the process. Verified at every gate. Traceable to every unit.
Quality verified
The quality system
Six layers of manufacturing confidence
Connected controls that prevent defects, detect variation early and protect every product release.
Process Control
Control SMT, soldering, assembly and test parameters with validated instructions and checkpoints.
Process window · SPCInspection & Test
Combine visual inspection, SPI/AOI and X-ray where justified with electrical and functional tests.
Detect · Verify · RecordTrained Manpower
Role-based training, workmanship qualification, visual standards and periodic competency checks.
Train · Qualify · RevalidateQuality Documentation
Maintain controlled PFMEA, control plans, work instructions, inspection records and customer-specific requirements.
Revision-controlledContinuous Improvement
Use FPY, defect Pareto, root-cause analysis and corrective action to reduce recurrence and variation.
Measure · Improve · SustainQuality built into the flow
One controlled journey.
Zero assumptions.
Every stage leaves evidence. Every failed gate stops the flow until disposition.

Inspection with intent
See the defect. Stop the escape.
Inspection methods are selected according to package, risk, customer requirements and the product's critical-to-quality characteristics.
Visual & Automated Inspection
Layered inspection helps identify workmanship and assembly issues before they move downstream.

Standards & documentation
Quality that is documented, not assumed.
We align product and process controls with the applicable customer specification, workmanship criteria and quality-management requirements.
IPC-A-610
Electronic assembly acceptabilityWorkmanship criteria applied at the class and revision specified by the customer.
J-STD-001
Soldered electrical assembliesApplicable soldering material and process requirements, where contractually required.
ISO 9001

Standards are applied according to the contract, product class, agreed revision and verified capability. No certification claim is implied by this page; publish a certification badge only when the current certificate and scope are confirmed.
Customer quality documentation
The right document. At the right revision.
Risk becomes action. Action becomes a controlled shop-floor check.
RISK → ACTION
PFMEA
Spot process risk. Assign action. Verify the control.
