High-quality products for PCB assembly since 1984

Siebtronic was established in 1984 by Franz Grubmüller in Oberndorf. Even then he recognised the significance of high-quality precision screens for PCB assembly. Through personal dedication and continuous improvements in quality, the company grew quickly and expanded its initial core business. The company began producing SMD stencils in 1995, with the laser precision cutting service in high demand. In the meantime, the company added three high-precision laser cutting machines to its technical equipment. From its humble beginnings as a one-man company, Siebtronic has become a market and technology leader in Austria.  

In 2014, the second generation took the helm, with brothers Franz and Andreas Grubmüller in charge of the company's fortunes since then. Much like their father before them, they both value personal contact with the customer and trusting partnerships with the suppliers. These include Koki, who produce soldering materials, and Zestron, who produce precision cleaning agents play key roles.

Precision screens, laser precision cutting, SMD stencils, soldering materials and cleaning agents – all available in premium quality from Siebtronic.

In light of advancing globalisation, but also resulting from the wish to have Siebtronic's high quality standards confirmed by an independent party, ISO certification was top of the agenda when the brothers took over. As per its mission statement ‘Quality = continuous improvement’, the company also aims to keep its machinery in line with the state of the art. So shortly after taking over they invested in two new machines, including a machine for producing stepped stencils.

We are well equipped for the future, which means our customers are too. Whether it's precision screens, SMD stencils, soldering materials from Koki, cleaning agents from Zestron or our laser precision cutting service – with us, your PCB assembly and much more is in experienced hands.



What sets us apart? Everything for SMD assembly, and much more besides …

There aren't many products that rely as heavily on precision as those that we produce for our customers in the broad area of SMD assembly. The quality of our customers' products depends on the quality of ours. Quality assurance is one of our top priorities, that's why we have put in place a multi-level quality management system.

A sense of responsibility and a high awareness of qualityform the central pillars of Siebtronic's company philosophy.

These are supported by values on which we place particular importance as a well-established company that wants to develop in a positive manner. These include honesty and openness in our dealings with customers and partners, as well as reliability and flexibility.

These values were embodied right from the start by Siebtronic's founder Franz Grubmüller, who was well aware that they gave the company a USP in comparison to the larger suppliers of products for SMD assembly. He proved himself to be a visionary in this respect, as is still evident today, with Siebtronic having grown from a one-man operation to the market leader in Austria.

SMD assembly is a matter of trust – even within the company

We are fully aware that the success of Siebtronic is directly linked to the performance and commitment of our staff. We see these as invaluable assets in the development of the company. It is therefore equally important for us to be respectful in our dealings with all of our employees and to offer them regular training opportunities.

Companies that not only want a fully technically equipped partner for their PCB production and SMD assembly, but that also value honesty, integrity and reliable quality, are in exactly the right place with Siebtronic. Get in touch and get to know us!
