Photonics System on growth path

By Antonio Cives, Managing Partner

The Photonics Systems Group is establishing itself as a renowned machine manufacturer for laser micromaterial processing. The acquisition of Proaut Technology has strengthened its semiconductor division. The trimming business is newly positioned under the L-Tris brand and aligned specifically to customer requirements. A new and much more spacious building in Krailling with larger production capacity, state-of-the-art laboratory and cleanroom provides the basis for future growth.

At the end of 2021, the Photonics Systems Group (PSG) acquired Proaut Technology GmbH as part of the succession from the founder and partner Helmut Muchow. Proaut is an established and innovative provider of process automation solutions in the fields of microelectronics and semiconductor technology based in Berlin. One of the company’s specializations is precision measurement machines for electronic components on wafers and panels. As part of PSG, Proaut benefits from synergies in the areas of sales, services and development and provides the Group with an additional growth platform.

A comprehensive offering

Proaut ideally complements the PSG product and services portfolio in microelectronics and semiconductor technology. The Group’s global sales channels enables a broader client base to benefit from the comprehensive offering with additional products and an even better service offering. PSG has expanded its range of competencies and strengthened its innovative capacity through the acquisition and resulting scope for crossdisciplinary exchange in research and development.

New markets

Proaut notably gives the Group access to the rapidly growing 5G technology market. Its solutions enable the testing of radio frequency filters and microphones used in consumer electronics – mobile phones, tablets, smart watches etc. – or for connectivity and the Internet of things – smart homes, electromobility etc. This also opens up cross-selling opportunities with existing clients in sister companies.

Consolidation of Trimming business unit

In 2019, PSG established the basis for the Trimming business unit when it acquired LS Laser Systems and EPP Electronic Production Partners. At the end of 2020, it combined the two companies and their laser trimming expertise into the new L-Tris.

L-Tris has emerged as a leading global manufacturer of laser systems for trimming circuits and wafers used to produce sensors and thick and thin film chips. The company serves a renowned clientele in Europe, North America and Asia. There are over 1,000 L-Tris machines installed all over the world.

Optimal location

In late summer 2021, PSG completed another fundamental milestone in the integration and consolidation of the Group and merged the four locations around Krailling into a new building in Krailling Innovation Mile. The new company location with 1,000m2 of production space also has an ISO class 6 cleanroom for manufacturing machines used in semiconductor technology. A state-of-the-art laboratory of more than 200m2 with the latest technology covers the Group’s entire product range. PSG has a wealth of laser sources and inspection equipment with which to test varied and technologically advanced potential applications for clients.

Sustaining the growth rate

PSG aims to increase headcount at its locations in the US and Asia over the coming months in order to meet client requirements for local sales and service support.

The company also wants to maintain its above-average growth in all areas over the coming years. The growth will be both organic and acquisition-based and cover all Group locations. The company is therefore living up to its claim of being a leading global micromaterial processor.
