Corrosion in Microelectronics (1 day)

Course Overview                                                                                         (Online Registration)

Corrosion is responsible for more than 50% of microelectronic device failures. It is dependent on the package type, electronic materials, fabrication and assembly processes, and environmental conditions (such as humidity, contaminants, temperature, stress and electrical bias etc.) This course thoroughly and systematically covers the causes and prevention of corrosion in microelectronics.

This corrosion short course can be taken as in-house training course, online course and distance learning course worldwide. It can also be customized to meet the specific needs of your organization.

All corrosion courses can be conducted at any time for you as in-house training courses or distance-learning courses. There is no minimum or maximum number of participants required for each course. Public corrosion short courses, seminars and workshops are also conducted regularly. If you are concerned with corrosion in your business, in-house training is a great solution to train a group of employees from Production, Quality Assurance, Inspection & Maintenance, and Technical Sales & Support on corrosion control & corrosion prevention technology. Contents of all corrosion courses can be customized to fit your organization's needs. Requests for in-house training courses, online courses & distance learning courses from overseas countries are also welcome. Click here for course registration online.
 

All corrosion courses can be conducted through online or distance learning. A master hard copy of corrosion course notes can be mailed to your organization or a password may be issued to course participants for accessing the online course materials. Instructions, course assignments, discussions and questions related to the corrosion courses are posted to the website or exchanged through email for a period up to 12 months. Click here for course registration online.

If you are involved in teaching corrosion courses, you may wish to purchase a complete set of the PowerPoint slides and the computerized test banks (in MicroTest format) with solutions. These presentations are suitable for teaching corrosion courses at different levels (from undergraduate to postgraduate) and durations (from 6 hrs to 40 hrs). The PowerPoint slides can be easily edited and customized to your own styles. The test bank contains over 1,000 questions for your use in tutorials, quizzes, tests or examinations. These questions are conveniently grouped into 4 categories in the test bank: (1) true or false, (2) multiple choice, (3) calculation, and (4) reasoning & open-ended discussions).  If you need more information, please contact Corrosion Clinic.
