TQ | More than an EMS Service Provider

An EMS provider (Electronic Manufacturing Services) handles the production of electronic assemblies based on fully developed designs, including PCB assembly, system integration, quality assurance, and logistics. They are typically involved only in later project stages, once the design has already been finalized, which means that potential optimizations in terms of manufacturability, testability, or material availability may remain unused.

EMS stands for Electronic Manufacturing Services. A traditional EMS service provider focuses on contract manufacturing and production of electronic assemblies. 

An E²MS service provider such as TQ becomes involved much earlier in the process—starting with product development. The additional “E” in E²MS stands for Engineering, making it Electronic Engineering & Manufacturing Services. As an E²MS system supplier, TQ covers not only hardware, software, and mechanical development, but also validation and certification, manufacturing, and complete lifecycle management. As a result, customers receive more than manufactured products—they gain a partner who supports and takes responsibility for the product from the initial idea through to after-sales service.

TQ’s E²MS model covers the entire product lifecycle through four core pillars: development, manufacturing, validation, and supply chain management.
The process begins with product development, supported by continuous testing and resulting optimizations. Particular emphasis is placed on approaches such as Design for Manufacturing (DfM) and Design for Testing (DfT) to ensure products are optimized for efficient production and reliable verification from the outset.
Following development, TQ manufactures prototypes, small series, and medium-volume production runs at one of its eight harmonized and certified production sites across Europe, China, and the USA. TQ also supports industrialization and the transition to series production, as well as product certifications for international markets through its in-house accredited test laboratory, the TQ Product Compliance Center (TQ-PCC).
Beyond manufacturing, TQ supports products throughout their entire lifecycle—from concept to end of life—with comprehensive supply chain management. This includes strategic sourcing, logistics concepts, after-sales services, and proactive obsolescence management to ensure long-term product availability and supply chain resilience.

For decades, TQ has developed and manufactured solutions for technologically demanding industries and applications, including aviation, medical technology, robotics, transportation, IoT and industrial systems, agricultural technology, energy and smart grid, as well as drive technology. These industries are characterized by high requirements for reliability, long-term availability, certifications, and compliance with strict regulatory standards. TQ addresses these challenges with deep system expertise and extensive industry-specific development and manufacturing know-how.

TQ is the right partner for any company looking to develop and/or manufacture electronic products – from medium-sized businesses to international corporations. Customers receive reliable support in every project phase and a tailored service package. TQ is particularly suitable for projects with high quality requirements, long product lifecycles, and the need for a long-term system partner rather than a pure contract manufacturer.
