Microchip Technology's Nantes manufacturing site has received an expansion of its MIL-PRF-38535 Qualified Manufacturers List (QML) certification to include Class Y. The upgrade, which adds to the site's existing Classes Q and V certifications in place since 1999, enables the facility to handle additional packaging technologies including non-hermetic solutions used in aerospace and defense, and supports qualification work for Microchip's PIC64-HPSC spaceflight processors. The announcement preceded a 2.6% rise in Microchip shares in premarket trading.

Key Points

  • Nantes facility expanded MIL-PRF-38535 QML certification to include Class Y, in addition to existing Classes Q and V.
  • Class Y enables support for additional packaging technologies, including non-hermetic solutions for aerospace and defense, and qualifies the site to test PIC64-HPSC spaceflight microprocessors.
  • Microchip now has multiple U.S. and European qualification sites with varying MIL-PRF certifications, and shares rose 2.6% in premarket trading after the announcement.

Microchip Technology reported that its Nantes, France manufacturing site has been granted an expansion to its MIL-PRF-38535 Qualified Manufacturers List (QML) certification to now include QML Class Y. The company said the expanded accreditation increases the facility's technical scope beyond the existing Q and V classifications.

Certification scope and capabilities

According to the company, adding Class Y to the Nantes site's credentials permits support for a broader set of packaging technologies, explicitly including non-hermetic solutions intended for aerospace and defense uses. The site had previously retained QML Classes Q and V since 1999.

Microchip described the Class Y qualification as enabling the Nantes plant to accommodate greater levels of integration and more advanced semiconductor architectures that the company says are required by next-generation military and space programs. The facility is also equipped to support qualification and testing for Microchip's PIC64 High-Performance Spaceflight Computing (PIC64-HPSC) family - a line of 64-bit microprocessors that the company describes as radiation-hardened and radiation-tolerant for space exploration applications.

Global qualification footprint

With the new accreditation, the Nantes location joins Microchip's San Jose, California site as company facilities qualified to MIL-PRF-38535 Classes Q, V and Y. The Nantes site also holds ESCC QML and AS9100:2018 certifications.

Microchip maintains multiple qualified sites across the United States and Europe. In the U.S., the company lists its Garden Grove, California site as supporting Class Q for analog and mixed-signal devices. Its Lawrence, Massachusetts location is cited as holding capabilities under MIL-PRF-19500 and MIL-PRF-38534 Classes H and K for discrete and hybrid microelectronics. In Europe, Microchip's Ennis, Ireland facility is certified to MIL-PRF-19500 for discrete manufacturing.

Market reaction

Microchip Technology shares rose 2.6% in premarket trading on Thursday following the announcement of the Nantes certification expansion.


Note on reporting

This report summarizes the company-stated certifications, facility capabilities and related trading reaction. The company statements form the basis of the details above.

Risks

  • The article does not provide information on production capacity or timelines at the Nantes facility following certification - this may affect how quickly new capabilities can be deployed (impacts semiconductor manufacturing and aerospace supply chains).
  • No financial impact, contract awards, or revenue implications are disclosed in the announcement - the certification expands technical capability but does not by itself guarantee program wins (impacts Microchip's defense and space contracting prospects).
