Kingdta — PCB & PCBA Manufacturer
ISO 9001:2015

ISO 9001:2015 Certified Quality Management System

Kingdta's entire PCB assembly operation — from component receiving to final shipment — is certified to ISO 9001:2015, the world's most widely recognised quality management standard.

Certified Since 2015 Annual Surveillance Audits Covers Full Manufacturing Scope Continuous Improvement Culture

What Is ISO 9001:2015?

ISO 9001:2015 is the international standard for Quality Management Systems (QMS), published by the International Organization for Standardization (ISO). It defines a framework of processes, documentation, and controls that an organisation must maintain to consistently deliver products and services that meet customer and regulatory requirements.

The 2015 revision introduced a risk-based thinking approach, requiring certified organisations to proactively identify and address risks that could affect product quality — not just react to defects after they occur. It also strengthened requirements around leadership commitment, context of the organisation, and knowledge management.

Over one million organisations in 170+ countries hold ISO 9001 certification. For electronics manufacturing, it is widely considered the baseline quality credential that serious buyers require from their supply chain partners.

What This Means for Your Project

Consistent, Documented Processes

Every step of your PCBA order — from BOM review and component sourcing to SMT, reflow, inspection, and shipping — follows documented, audited procedures. No improvisation.

Full Traceability

ISO 9001 requires records at every stage. If a quality issue arises, we can trace exactly which components were used, which operator ran which machine, and at what time — critical for medical and automotive customers.

Risk-Based Quality Control

We proactively identify high-risk process steps (BGA soldering, fine-pitch SMT, mixed assembly) and apply additional controls — not just standard inspection — to prevent defects before they occur.

Third-Party Verified

Our ISO 9001:2015 certificate is issued by an accredited certification body and renewed through annual surveillance audits and triennial recertification audits — not a self-declaration.

Supplier Quality Management

ISO 9001 requires us to evaluate and monitor our component suppliers. We source from authorised distributors (Digi-Key, Mouser, Arrow) and maintain an approved vendor list with periodic performance reviews.

Continuous Improvement

Internal audits, management reviews, and corrective action processes are mandatory under ISO 9001. Our quality metrics — defect rates, on-time delivery, customer complaints — are tracked and improved every quarter.

How Kingdta Implements This Standard

01

Quality Management Manual & Procedures

We maintain a full QMS documentation set including a Quality Manual, 20+ Standard Operating Procedures (SOPs), and work instructions for every critical process step.

02

Incoming Quality Control (IQC)

All components are inspected against approved specifications upon receipt. Reels are verified for correct part number, quantity, and date code. Counterfeit-prevention checks are applied to high-risk components.

03

In-Process Controls (IPQC)

First-article inspection (FAI) is performed at the start of every production run. SPI (Solder Paste Inspection) checks paste deposition before component placement. AOI is performed after reflow on every board.

04

Corrective & Preventive Action (CAPA)

Any non-conformance triggers a formal CAPA process. Root cause analysis is documented, corrective actions are implemented, and effectiveness is verified before closure.

05

Internal Audits & Management Review

We conduct quarterly internal audits across all departments. Annual management reviews assess quality objectives, customer feedback, and process performance against targets.

Frequently Asked Questions

Does ISO 9001:2015 certification cover PCB assembly manufacturing?
Yes. Kingdta's ISO 9001:2015 certification covers the full scope of our PCB assembly manufacturing operation, including component receiving (IQC), SMT and DIP assembly, soldering, AOI and X-ray inspection, functional testing, and final packaging and shipment. The certification is issued by an accredited third-party certification body and renewed through annual surveillance audits.
What is the difference between ISO 9001 and IPC-A-610?
ISO 9001 is a process management standard — it certifies that a company has documented, consistent processes for delivering quality products. IPC-A-610 is a product workmanship standard — it defines the specific visual acceptance criteria for solder joints, component placement, and other assembly characteristics. Both are complementary: ISO 9001 ensures the processes are in place, while IPC-A-610 defines what a good PCBA looks like.
Can I request a copy of Kingdta's ISO 9001:2015 certificate?
Yes. We can provide a copy of our current ISO 9001:2015 certificate upon request. Please contact us at info@kingdta.com or use the quote form to request a copy. The certificate includes the certification body name, scope of certification, certificate number, and validity dates.
Does ISO 9001 certification guarantee zero defects?
ISO 9001 does not guarantee zero defects, but it significantly reduces defect rates by requiring systematic process controls, incoming inspection, in-process monitoring, and corrective action processes. Our internal defect rate data shows that ISO 9001 implementation has reduced our customer-reported defect rate by over 60% since certification.
Is ISO 9001 required for medical or aerospace PCB assembly?
ISO 9001 is typically the minimum quality management requirement for medical and aerospace PCB assembly. Medical device manufacturers often additionally require ISO 13485 compliance, while aerospace customers may require AS9100. We are ISO 9001:2015 certified and can discuss specific quality requirements for your application during the quoting process.
