Stage 1
IQC
Incoming material, supplier documents, and program-specific requirements are checked before work begins.
Quality Systems
Documented inspection, held ISO systems, and qualification support from material intake to shipment release.
Quality Baseline
Control is defined before production starts
SIKING positions quality as a routed system, not a final inspection promise. Material review, in-process checks, finished-part approval, and shipment release all sit inside the same published quality boundary.
- Held ISO 9001:2015 and ISO 14001:2015 systems
- Four quality gates: IQC, IPQC, FQC, and OQC
- Published targets kept visible during supplier qualification
- Documentation routes raised before tooling or launch decisions

Qualification Route
Quote first, documentation aligned early
Four Quality Gates
One inspection rhythm from intake to release
The quality route stays simple on purpose: incoming materials are checked before production, in-process checks confirm stability, final review clears finished parts, and outgoing checks confirm shipment readiness.
That structure gives buyers a practical review path without inventing extra certifications or unsupported lab claims.
Stage 2
IPQC
First articles, key dimensions, and process consistency are reviewed during production, not after the fact.
Stage 3
FQC
Finished parts are checked against the agreed release package before an order is cleared internally.
Stage 4
OQC
Shipment release covers quantity, packaging, and the required documentation route for the program.
Qualification Review
What buyers can review without crossing the fact boundary
The trust cluster works best when held systems, published targets, and documentation routes stay clearly separated.
ISO
Held Certifications
Review the currently held ISO management systems and download the published certificates.

Documentation Handoff
Raise the document scope before the route is locked
Medical, automotive, or customer-specific requirements should be raised during quotation so the qualification package matches the route from the start.
- Share the latest drawing set, revision status, and critical dimensions
- Flag supplier or material preferences before DFM and quotation
- Confirm if RoHS or REACH documentation will be required for the program
Published quality metrics
- DPPM: <= 1,000
- First-pass yield: >= 97%
- Acceptance rate: >= 98%
Public-safe compliance position
RoHS and REACH are handled as documentation flows for applicable programs. They are not presented as extra held certifications.
Need qualification documents or an early quality review?
Start through the quote route when the program is ready for technical review, or use the standards page first if your team needs to align the qualification scope.
