KINGBROTHER received SGS certification from AS9100 Aerospace Quality Management System

KINGBROTHER recently passed the AS9100 aerospace quality management system certification issued by SGS. This qualification officially allows the company's PCB manufacturing and electronics manufacturing service capabilities to be incorporated into the qualified supplier system of the international aerospace supply chain.

The weight of AS9100 standard in supplier evaluation

AS9100 was developed by the International Aerospace Quality Organization (IAQG) and is based on ISO 9001 and adds about 80 special requirements for the aerospace industry. These additional terms cover dimensions such as product safety, reliability, traceability, configuration management, anti-counterfeiting component control and special process verification, and are far more stringent than the general ISO 9001. In Europe, the same standard is released in the form of EN9100 and is called JISQ 9100 in the Asia-Pacific region. The three are completely equivalent in technical content and recognize each other. AS9100 is the latest revision, which further strengthens regulations on risk management, product safety requirements and organizational knowledge management.

Boeing, Airbus, China Commercial Aircraft and other complete aircraft manufacturers have listed AS9100 certification as a basic prerequisite in the supplier access process. Suppliers lacking this qualification will be excluded from the shortlist during the technical capability assessment stage. The scope of application of AS9100 covers key aspects such as design input review, supplier control, production process traceability, special process verification and non-conforming product control, requiring suppliers to establish an auditable record chain on each core process. From the entire process of tracing raw material batches to the shipment of finished products, every operation must be documented and traced. Missing records in any link may become a non-conformance during the review. When evaluating potential PCB suppliers, the procurement team can regard AS9100 certification as an endor*t of a mature supplier's quality management system, reducing investment in the self-audit system.

SGS review process endorses the credibility of supplier qualifications

In terms of the selection of certification bodies for AS9100, SGS is the world's leading inspection, verification, testing and certification body. The strictness of its audit process and the international recognition of its certificates constitute core considerations. SGS's audit team is usually composed of experts with a background in aerospace engineering and can assess whether a company's process capabilities meet industry requirements from a technical level, rather than just checking the compliance of a document list. This technology-oriented review method makes the certification results more reference value to the international procurement team. For purchasers, suppliers hold AS9100 certificates issued by SGS, which means that their quality management system has been fully verified from documents to site by independent third parties.

Moreover, the provisions of the AS9100 standard focus on whether the program design of product safety, anti-counterfeiting component control, configuration management and risk management is complete. In-depth on-site audit of the production workshop and conduct on-site observations and record spot checks on key PCB manufacturing processes. Taking the lamination process as an example, the auditor will retrieve the lamination temperature curve records for the past three months, check the consistency of the actual parameters with the process regulations, and check whether the equipment calibration certificate is within the validity period. The review of the drilling process focuses on the batch stability of drilling parameters and whether tool life management meets regulations, while the plating process requires providing thickness inspection reports and bath fluid analysis records. KINGBROTHER has accepted a complete audit process, and its quality management system has passed the certification audit coverage of the AS9100D standard, providing flexibility for global customers to choose nearby delivery and capacity backup at different project stages.

Practical value brought to the project by selecting an AS 9100D certified supplier

International aerospace projects usually have stricter qualification requirements for suppliers than general industrial projects, especially in terms of traceability and document management. Including PCB suppliers with AS9100D certification in the Approved Vendor List (AVL) provides the project team with practical value at multiple levels.

The significant shortening of supply chain access cycles is the primary value brought by certification. Many aerospace OEMs and Tier 1 suppliers use AS9100 certification as the first threshold for screening when evaluating potential PCB partners, and uncertified suppliers will be excluded during the qualification review stage. When the procurement team includes AS9100 certified suppliers such as KINGBROTHER into the AVL list, there is no need to conduct additional system reviews, the supplier qualification certification cycle is correspondingly shortened, and the project start time is advanced. For defense and aerospace projects with strict compliance requirements, the supplier qualification review cycle usually lasts as long as three to six months, and the existence of AS9100 certification can compress this cycle to less than a few weeks.

The improvement of the quality traceability system constitutes the second level of value. AS9100 requires suppliers to establish a complete traceability chain from raw materials to finished products. The plate batches, copper foil specifications, drilling parameters, plating records and inspection data of each PCB can be traced back to specific operators and specific times. For aerospace projects, this traceability capability has irreplaceable value in quality problem investigation and root cause analysis. When an abnormality occurs in the terminal product, it is possible to quickly locate the source of the problem and assess the scope of impact to avoid the risk of large-scale recalls and line outages. In a satellite communication control board project, abnormal impedance deviations were found in the downstream assembly process, and PCB suppliers were required to provide complete process data for root cause analysis. Relying on the traceability records established under the AS9100 system, KINGBROTHER completed the full-process data retrieval of this batch of cards within 24 hours, assisting the project team in locating the problem to the connector crimping process deviation in the assembly process rather than the PCB manufacturing process itself. The value of this rapid response capability in aerospace projects far exceeds that of conventional commercial projects, directly affecting project schedule and cost control. Continuous verification of special processes provides long-term guarantee of process stability. Processes such as lamination, plating, solder resist and surface treatment in aerospace PCB manufacturing are classified as special processes, and their quality cannot be fully verified through subsequent testing. AS9100 requires initial verification and periodic re-verification of these processes to ensure that process parameters remain under control. The special process verification system established by KINGBROTHER during the certification process includes SPC (Statistical Process Control) monitoring of lamination temperature curves, Cpk (Process Capability Index) analysis of plating thickness and regular random inspection plans of solder resist thickness, providing international customers with long-term data support for process stability and reducing the risk of quality fluctuations in mass production. These verification data can be directly invoked during customer reviews or project milestone reviews, reducing the purchaser's investment in independent verification.

Synergies between PCB suppliers 'technical capabilities and certification

AS9100 certification provides a system guarantee for quality management, while the accumulation of technical capabilities by suppliers determines the engineering implementation effect of the certification value. The technical requirements of aerospace PCBs are concentrated in three directions: high reliability, extreme environmental tolerance and long-term life assurance. When evaluating suppliers, it is necessary to cross-verify certification qualifications and specific technical capabilities.

KINGBROTHER's testing system is equipped with a complete set of methods such as AOI (Automatic Optical Inspection), X-RAY Inspection, Flying Probe Test and Impedance Test, and its testing capabilities meet the requirements of the IPC-6012 Class 3 standard. Aerospace PCBs are usually required to reach Class 3, which puts forward stricter requirements than Class 2 for hole wall quality, wire accuracy, solder resist thickness and interlayer alignment accuracy. Environmental testing capabilities cover high and low temperature cycling (-55 ° C to +125 ° C), moist heat aging, salt spray testing and insulation resistance testing. The test plan can be customized according to the specific deployment environment of the project. The collaboration of these technical capabilities with the AS9100 architecture framework enables the project requirements to be met simultaneously in both the dimensions of system compliance and engineering realization when undertaking aerospace PCB projects.

Supplier selection strategies in the context of supply chain diversification

The global aerospace supply chain is undergoing structural adjustments. Geopolitical factors and changes in trade policies have prompted many international aerospace companies to reassess their PCB supply sources, and their supply chain diversification strategies have changed from "optional" to "must-have." In this context, PCB suppliers with AS9100 certification have a natural advantage in the evaluation of supply chain backup solutions.

KINGBROTHER has a monthly production capacity of more than 100,000 square meters, providing international customers with greater flexibility in capacity allocation and emergency delivery. The company's rapid proofing capabilities shorten the sample delivery cycle to 24 hours, a response speed that matches the delivery pace of aerospace projects during prototype verification, design iteration and small-batch pilot production phases. For aerospace teams that need to carry out design freezes and engineering change management in multiple project phases, the supplier's delivery elasticity directly affects the project schedule and the efficiency of implementing engineering changes.

The global aerospace electronics market has maintained a compound annual growth rate of more than 5%, with the growth in demand for high-reliability PCBs in emerging areas such as commercial drones, satellite Internet and electric aviation particularly evident. Most of the customers in these emerging fields are entrepreneurial technology companies. The certification requirements for suppliers are as strict as those for mature OEMs, and the decision-making cycle is shorter. They are more inclined to choose suppliers that have passed AS9100 certification to simplify their own supply chain management. KINGBROTHER's AS9100 qualification provides access conditions for entering these emerging markets. The company provides customers with full-process support from design to mass production through the IPDM (Integrated Product Development and Manufacturing) model, reducing the management costs of customers coordinating between multiple suppliers.

In the comprehensive consideration of supplier evaluation, the engineering value of AS9100 certification is reflected in the improvement of the traceability system, the systematization of special process verification, and the pre-positioning of quality risk management and control. Selecting a PCB supplier holding this certification is equivalent to obtaining verification and endor*t of the supplier's quality management system by an independent third party at the early stage of the project, reducing later quality risks and audit investment. Against the backdrop of rapid development of emerging applications such as satellite Internet, commercial drones and electric aviation, PCB suppliers with AS9100 certification will play a more critical role in the global aerospace supply chain. KINGBROTHER's continuous investment in aerospace PCB process development and testing capabilities provides international customers with dual technical and institutional support for quality assurance during the prototype verification and mass production stages.
