Vacuum Technology for the Electronics Industry

With increasing digitization and connectivity in almost every industry, not only the demand for electronic components is increasing, but also their complexity. In the automotive, consumer electronics (handsets), infrastructure and aviation sectors, for example, the demands placed on parts and components are constantly increasing. New production technologies and miniaturization are the results. In the semiconductor sector, increasingly better and more powerful chips are manufactured, which are further processed in complex processes in the packaging sector. Due to the steadily decreasing form factor, PCB manufacturers and developers are required to generate more complex circuits and to manufacture them reliably. The high demand for electronic devices also requires manufacturers in all areas to improve their processes, increase throughput and achieve YIELD increases. Automation and information processing are part of this process. Safe and sensitive handling of components and products within the process chain are becoming increasingly important. Vacuum technology and the associated vacuum systems make it possible to meet the requirements. Thanks to Schmalz’s expertise in the field of vacuum technology and the associated knowledge of the electronics industry, Schmalz can offer the right solutions for the most advanced processes. In addition, new products are constantly being developed to meet the increasing requirements in the individual areas of semiconductor, printed circuit board and end product production.

Vacuum Technology during the Manufacturing of Printed Circuit Boards

During the manufacturing of printed circuit boards, vacuum and vacuum technology can be used at various points in the process chain. Schmalz distinguishes between PCB handling (automation) in the process chain and process vacuum within a production step, for example when clamping workpieces. The following table shows the essential process steps and gives an overview of the areas in which Schmalz vacuum technology can be used in the manufacturing of printed circuit boards.
Vacuum Technology for Printed Circuit Board Assembly

Following the manufacture of blank printed-circuit boards (PCBs), the boards are assembled with various electrical parts and components. Resistors, IC chips, capacitors and all manner of interfaces are used in the PCB assembly, depending on the individual requirements and layout. The high number of different components, along with their diverse geometries and properties, places very high demands on the necessary vacuum technology. High cycle times and positioning accuracy are additional requirements that can be addressed with vacuum technology from Schmalz.
