Precision Engineering and Microengineering

Module name (EN):
Name of module in study programme. It should be precise and clear.
Precision Engineering and Microengineering
Degree programme:
Study Programme with validity of corresponding study regulations containing this module.
Mechatronics and Sensor Technology, Bachelor, ASPO 01.10.2020
Module code: MST2.FMF
SAP-Submodule-No.:
The exam administration creates a SAP-Submodule-No for every exam type in every module. The SAP-Submodule-No is equal for the same module in different study programs.
P231-0042
Hours per semester week / Teaching method:
The count of hours per week is a combination of lecture (V for German Vorlesung), exercise (U for Übung), practice (P) oder project (PA). For example a course of the form 2V+2U has 2 hours of lecture and 2 hours of exercise per week.
3V+1P (4 hours per week)
ECTS credits:
European Credit Transfer System. Points for successful completion of a course. Each ECTS point represents a workload of 30 hours.
5
Semester: 5
Mandatory course: yes
Language of instruction:
German
Assessment:
Written exam 120 min.

[updated 06.11.2020]
Applicability / Curricular relevance:
All study programs (with year of the version of study regulations) containing the course.

MST2.FMF (P231-0042) Mechatronics and Sensor Technology, Bachelor, ASPO 01.10.2019 , semester 5, mandatory course
MST2.FMF (P231-0042) Mechatronics and Sensor Technology, Bachelor, ASPO 01.10.2020 , semester 5, mandatory course
Workload:
Workload of student for successfully completing the course. Each ECTS credit represents 30 working hours. These are the combined effort of face-to-face time, post-processing the subject of the lecture, exercises and preparation for the exam.

The total workload is distributed on the semester (01.04.-30.09. during the summer term, 01.10.-31.03. during the winter term).
60 class hours (= 45 clock hours) over a 15-week period.
The total student study time is 150 hours (equivalent to 5 ECTS credits).
There are therefore 105 hours available for class preparation and follow-up work and exam preparation.
Recommended prerequisites (modules):
MST2.DAS
MST2.DIF

Learning outcomes:
After successfully completing this course, students will be familiar with the most important manufacturing processes of DIN 8580 with special reference to precision engineering. They will also be familiar with technological features such as operating principles and process parameters. Students will be able to assess the application areas of the processes and materials. They will have extended their knowledge about mechanics. And thus, link that knowledge with the content discussed in the course.
Students will be familiar with the most important manufacturing processes in microtechnology, their fields of application and MEMS design examples. They will understand precision and microtechnical products and their manufacturing processes.
