• Detection even when holes or openings are present

  A challenge in this area is the reliable detection of circuit boards with different colors, surfaces, and equipment. Thanks to their extra large light spot, the special sensor solutions from Leuze electronic function very reliably even where other sensors fail due to holes or openings. An additional advantage is the problem-free maintenance of the systems.

• From wafer to chip

  Before separating the individual chips, the rear side of the wafer is worn down by polishing or cauterizing until the final thickness is attained. Then the individual chips are sawed apart. Sawing and grinding are two of the critical processes for achieving a high yield, and they must be completely controlled, monitored and safeguarded with sensors.

• To the right circuit with the right mask

  The so-called front end in the production of integrated circuits deals with the manufacture of electrically live construction elements such as transistors, capacitors, etc. under clean room conditions. 2D-code readers from Leuze electronic are used here, e.g. for decoding masks labeled with IDs from the mask SMIF pod (Standard Mechanical InterFace), which are needed for the exposure of the circuits.

• Precise work in every aspect

  Absolute precision is required for the production of semiconductor wafers in clean rooms. Automated processes reduce the probability of errors and enable consistent product quality of the extremely thin wafers. These processes are controlled and monitored with our sensors and, for example, the wafers in the FOUP are correctly detected. In addition, these systems reliably detect notches/flat areas on the wafer edge, what is necessary for centering.

• From individual parts to a functioning product

  After the circuit boards are equipped, they are mounted to other components to make finished products. During the final mounting process, automatic tests are performed to ensure and monitor that all circuit boards and mechanical attachments are present and in the correct position. Excellent sensor solutions from Leuze electronic, such as the smart camera, can be used for these quality inspections.

• Efficiently equipping circuit boards

  When equipping circuit boards with electronic components, our sensors are confronted with many different challenges. These include highly diverse, sometimes strongly reflective surfaces, very small components and high cycle rates. For these tasks, Leuze electronic offers an extensive selection of product solutions for all types of applications as well as expansive practical application know-how.
