 Course Overview

 

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 and semiconductor industry.

 

This 2-day 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.

 In-House Training Corrosion Courses

 

If you are concerned with corrosion in your business, in-house training is a great solution to train a group of employees from design, production, operation, quality assurance, inspection and maintenance, and technical sales and support on corrosion control and corrosion prevention technology. The contents of all corrosion courses can be customized to fit your organization's needs.

 

There is no minimum or maximum number of participants required for in-house training corrosion courses. We conduct the in-house training corrosion course at your company's premises and at a time convenient to your company. Requests for in-house training corrosion courses from overseas countries are also welcome.

 Corrosion Course-On-Demand

 

All our publicly scheduled corrosion short courses are conducted once a year. However, you do not need to wait for one year if you have missed any of the publicly scheduled corrosion courses as we have this unique corrosion course-on-demand scheme: we will conduct the course just for you on an one-on-one basis at a time and in a location convenient to you. This option costs significantly less than a full-scale in-house training program.

 Online and Distance Learning Corrosion Courses


All corrosion courses can be conducted through online or distance learning. An username and password will be emailed to course participants for accessing the online course materials. Alternatively, a CD-ROM containing the same online course material or a master hard copy of corrosion course notes can be sent to your organization. Instructions, course assignments, discussions and questions related to the corrosion courses are posted on the website. Free email support for online courses is provided for a period up to 12 months. A Certificate of Completion will be issued to participants who pass the online test with a score of 70% and above.

 PowerPoint Slides and Test Banks for Trainers, Instructors, Tutors, University Lecturers and Professors

 

If you are involved in teaching corrosion courses, you may wish to purchase a complete set of 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). These ready-to-use corrosion PowerPoint slides contain high quality color photographs, illustrations, animations and video clips. They can also be easily edited and customized to your own styles. The corrosion test banks contain over 1,000 corrosion questions for your use in tutorials, 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 and open-ended discussions).
