Quality Management

Quality is an investment, not a cost. This applies to our customers as well as to us. A well-established quality management system allows us to systematically control all quality-related processes and thus to ensure the right quality of our products and services. Based on this foundation, we are able to make the most of our know-how and create value for our customers. Trustful and honest collaboration allows us to translate feedback into improvement and thereby achieve the highest level of customer satisfaction.

We aspire to always keep our commitments and to deliver the required quality. This is why our products undergo a dedicated qualification process. This process verifies the functionality, reliability and manufacturability of our products. It also ensures that the products are suitable for subsequent processing by our customer.

We take care of our employees and create value for our customers by investing significantly in innovation, technology, capacity and service to deliver best-in-industry performance and for a sustainable future.

MS Power fulfils international Quality Management Standards such as ISO 9001.

Qualification and reliability

We aspire to always keep our commitments and to deliver the required quality. This is why our products undergo a dedicated qualification process. This process verifies the functionality, reliability and manufacturability of our products. It also ensures that the products are suitable for subsequent processing by our customer.

Technology & product qualification

The related wafer technology and package technology are qualified prior to product qualification. This step includes detailed investigations of specific failure mechanisms. The procedure is further characterized by early identification of our customers’ needs; potential future market developments are also considered. Detailed reliability testing during the entire development phase of wafer and package technologies guarantees built-in quality for our products.

All qualification tests are performed according to international standards such as IEC (International Electro technical Commission).

Qualification and reliability

Dynamic Testing: In-house simulation of field conditions-Rated current passed through the device and Rated VDRM /VRRM applied when device is in OFF state and observed the blocking voltage characteristic on X-Y curve tracer and record IDRM /IRRM at specified case temperature.

Significance of dynamic test: Confirmation of Pw, Rth(j-c)

Supplier quality management

In order for us to be a quality leader, our suppliers have to fulfill a high level of quality expectations as well. MS Power follows Total supplier Management principles to ensure that all kinds of suppliers (suppliers of material, equipment and spare parts, silicon foundry, outsourced assembly and test manufacturing services) are in line with MS Power’s requirements and expectations with respect to functionality, on-time delivery and quality.

During the supplier selection process, a supplier undergoes a detailed evaluation and risk analysis on expertise, sustaining manufacturing capability and security. The supplier also has to fulfill prerequisites with respect to social responsibility and the maturity of its quality management system.

Operational performance control

MS Power monitors and reviews supplier operational performance to steer the supplier in order to meet our requirements. Compliance with expectations placed on the products and services provided is supported by audits and inspection methods which are aligned with those used in MS Power’s own manufacturing plants. In order to also meet and maintain our customer’s requirements, we are prepared to work together with our suppliers to implement sustainable improvements across the supply chain.

Change management and PCN

At MS Power we follow the global change management process, which describes how to introduce and manage changes to products and product realization processes up to delivery to the customer. The global change management process guarantees compliance with ISO 9001, industry-specific standards and individual customer contracts.

Change-specific and automated workflows control company-wide, cross-functional approval and information processes between manufacturing and business departments. Integrated risk assessment, a change-specific review by all stakeholders and release by change review boards at management level all contribute to our quality objective: zero defect regarding our commitments.

In case of major changes that may affect the form, fit or function of a product or adversely affect the product’s quality or reliability, MS Power informs the affected customers via a product/process change notification (PCN).

Complaint management and problem solving

Customer satisfaction is our highest priority. To achieve it, it is necessary to understand the customer’s needs and requirements. Equally important: in case we were not able to meet a requirement, it is crucial that we know about it. Based on this knowledge, we are able to improve our products and services. We aspire to thoroughly analyze the deviation, identify all root causes and eliminate them with long-term improvements, while preventing any form of re-occurrence. For this reason, we have established a well-functioning complaint management system along the entire value chain. Everyone supporting this process shares the common goal of correcting any deviation as fast as possible.

MS Power follows the 8D problem solving method to understand and correct a confirmed deviation. One main principle is to collaborate closely and transparently with each other as a team, as well as with the customer. In the event of a complaint, the customer interface validates all complaint information provided in terms of completeness, consistency and data accuracy. The customer interface also regularly updates the customer during the complaint handling process, from the verification to the final report. This is the basis of an ongoing strong and trustful partnership. Our complaint management process complies with international standards.

Failure analysis :

In the event of a customer complaint, FA investigates the root cause to prevent similar issues in the future. In case of a single failing device – which is typical for customer complaints – the failed device is analyzed according to a predefined analysis flow.

In verifying the reported abnormal behaviour of the device, a precise description from our customers of the device history (e.g. stress, application conditions and the observed failure behaviour) is crucial for a successful analysis. Depending on the complexity of this verification, bench measurements, application boards and sophisticated automated testing systems are used. In addition to the electrical test, the device is investigated using non-destructive methods such as x-ray.
