Details

1

Method of delivery

The participants are first taught the essential skills in mechanical engineering including GD&T, DFMA, tolerance analysis, and DOE.

The participants will then be taught stress analysis, finite element analysis, mechanical design for EMC, and plastic injection moulding technology.

Having acquired both pre-requisite knowledge and practical mechanical design and analysis skills, the participants would be able to perform a mechanical engineer’s task for EE industry.
