Component of the month - July 2021

Our component of the month July is about two core components for a vacuum table, which were manufactured for the Institute for Nuclear Physics of the Westfälische Wilhelms-Universität Münster.

The vacuum table represents a user-friendly clamping device and enables the exact and level clamping of large-format printed circuit boards for an assembly process. The aluminum head plate, which is also precision-milled and equipped with 1,680 suction holes, is placed on the precision-milled base plate with suction channels and sealed via a circumferential soft seal. The suction holes are connected to a vacuum pump via the suction channels on the base plate.

In this way, the component is evenly sucked in over the entire surface and securely fixed. The employees of the Institute of Nuclear Physics can thus ensure that their components remain fixed flat for the subsequent manufacturing process and that a very good flatness of the end product is guaranteed. 

The high precision in milling the aluminum plates is crucial for the final product, which is manufactured on the vacuum table. The aluminum plates are 1,200 x 1,200 mm in size. Another special requirement for the two precision aluminum plates is the roughness Ra <= 0.25 µm and the flatness < 0.15 mm.
