Introduction

4

Everfeed Technology Pte Ltd was founded in 1997 and hence is still a relatively young

company. The core business focuses largely on Electrostatic Discharge (ESD) related

matters. The 3 main categories of their services are 1) Consultation & Products, 2)

Training & Personal Certification and lastly, 3) Auditing & Maintenance.

The primary business stem from the following industries listed below:

1) Electronics & Electrical Manufacturing Industries

2) Front-End / Back-End Wafer Fabrication Industries

3) F&B Industries

For a relatively small establishment, Everfeed has a large and extensive network of

associates when it comes to electrostatic control. More notably, some of the customers

include Hewlett Packard (HP), Epson, Hitachi, STATSChipPac, Panasonic and Infineon.

Training Assignments

Week 1: Introduction to Company Operations and Basic ESD

When I initially entered the company, my very first task was to read

up on the company operations and the fundamentals of electrostatic

discharge. I was given 2 ebooks (ESD A to Z) and (ESD Control

Management) together with a range of product catalogues to read up

and to understand.

As the content of electrostatic discharge (ESD) are not taught to mechanical engineering

students (more applicable to electrical engineering), the concepts are relatively new and

foreign to me. Nonetheless, it is a good learning experience to be trained in a completely

new subject matter.

Furthermore, I had the privilege to accompany my fellow colleagues for site work at

United Test and Assembly Center Ltd (UTAC) and DSO National Laboratories to

experience first-hand the conditions of an actual cleanroom environment. This was the

first time I had to wear a full body ESD smock that consists of headwear, mask, smock,

ESD shoes and gloves.

To sum up week 1, it was a 1-week intensive revision of the concepts of ESD and to

know the products that the company deals with. The following are some of the ESD

control products:

Week 2: DSO product demonstration and SIMCO-ION product training

Week 2 started off with a

fundamentals MCQ test to

examine my ESD learning progress in which I scored 17/20. That being said, even though

it has been a week of intensive reading on ESD, I still have not fully grasp the entire

concept together. Hence, I was to continue revising on the 2 ebooks given to me.

Subsequently, my colleague was tasked to visit DSO for product

demonstration and training and thus I tagged along to learn more. The

products demonstrated were the 3M™ EM Eye Meter and the Charge

Plate Monitor.

The EM Eye meter is a versatile and multi-purpose instrument capable

of ESD event detection, Electromagnetic Field (EMF) Measurement

and RF Signal Sensor. More remarkably, it is competent to detect ESD

event and classify them into the various models (HBM, CDM & MM)

and rejecting non-ESD related events making analysis easier.

The charge plate monitor is mainly to test the performance of ionizers.

Typically, it was to be charged up to a certain potential (1000V), and

the time taken for an ionizer to reduce the monitor’s potential to 100V

is then measured.

Following that, I was also tasked to begin my preparation of the

power-point presentation for both Germany and the upcoming

Singapore ESD symposiums. I was to read up on the various technical

papers to gain insights to how to structure and to explain the new concepts brought forth

by the proposed technical papers.

Last but not least, the more significant event for the week was that the product training by

Mr. Pony Chiu (Asian Regional Manager) of SIMCO-ION. It was a comprehensive

training on their products and I really got to understand how the products can be

applicable and marketed to the industries.

Week 3: Initial Preparation of PPT for symposiums & ESD Training Course at DSO National laboratories

After reading up on the ESD eBooks and the various technical papers, I was more

equipped to start creating the power-points for the symposium. There are 3 different

power-points to be prepared on 3 different technical papers.

1) PPT 1 - ESD Process Capability Analysis & Probabilistic Analytical Benchmarking

2) PPT 2 - Evaluation of Length to Diameter Ratio of Grounding Wires

3) PPT 3 - Static Control Considerations for Automated Handling Equipment with High Temperature Testing

The challenge was that there was a lack of background information for me to understand

the whole situation and hence, at times, I was caught in a deadlock of not knowing how

to proceed with the presentation. However, with the help of my colleagues patiently

explaining to me, I was more aware of the issue and better organized to work on the

power-points.

The week then concluded with a 3-day advanced training workshop conducted at DSO

National laboratories. In a class of 9 DSO employees and 1 3M employee, my fellow

intern and I were able to sit in the course to finally complete our fundamental ESD

training by Mr Marcus Koh (Supervisor). I was glad that we are able to undergo the

course for free that is worth thousand over dollars.

During the 3-day course, we had numerous tests to evaluate our understanding of the

concepts and calculations. The results are as follows: Electrostatic Fundamentals (24/25),

ESDA standards and measurements (43/50), Electrostatic Calculations (20/25) and lastly

Mock-up iNARTE exam (95/100).

Week 4: Start of Marketing & Publicity of Singapore Symposium 2014

Week 4 began with the start of our marketing and publicity stunts aimed to raise

awareness of the ESD symposium (Aug 4-6). We sent out invitations for the event

through LinkedIn and publicised through the various social media platforms.

In addition, I was tasked to compare and summarise the various standards with regards to

the requirement of a Electrostatic Protected Area (EPA). The different standards are by

11

American National Standards Institute (ANSI), Joint Electron Device Engineering

Council (JEDEC) and International Electrotechnical Commission (IEC).

Week 5: Continuation of Marketing & Publicity of Singapore Symposium 2014

To add on to our publicity effort, we continued to publicise by mass-emailing the ESD

symposium brochure using the contacts database. Keeping in mind the spam control act

that was put in place to restrict malicious and spam mails, the mass emails were sent

batch by batch throughout the weeks.

Furthermore, following the submission of the technical paper for Germany symposium,

there is a peer-to-peer evaluation to validate the quality of the papers. Hence, I was given

the assignment to finish reading and to comment. They are graded based on 3 criteria, 1)

Novelty & Relevance, 2) Completeness of Data and 3) Quality of Analysis. The

following are the papers evaluated.

Week 6: Continuation of Powerpoint for ESD symposium Singapore to meet 1 st deadline (25 th June 2014)

With the 3rd Asian ESD symposium drawing nearer, publicity efforts had to be stepped

up. For the mass-emailing part, we completed sending to the 1700+ contacts on Google

mail and hopefully, the next round of effort can be continued. The tentative plan is to

send out personalised emails to previous years’ participants of the 1st and 2nd Asian ESD

symposiums in hope that we might be able to engage them and to draw their attention to

the upcoming symposium.

At the moment, publicity is still an issue as the sign ups for the symposium (tutorial +

technical session) remained well below the target. Hence, for the next few weeks to

come, it is imperative to come up with more innovative and effective ways to help market

the event.

On top of that, the 1st draft for the power-point titled “Static Control Considerations

For Automated Handling Equipment With High Temperature Testing” is due for

submission the following week on 25 th June , hence I had to revamp the current version to

include more photos, diagrams and hopefully, this can make the presentation much more

interesting and easier to understand. With the knowledge I have gained from the past few

weeks of internship, I believe I am more able to grasp the concept relatively better.

Conclusion

13

At the end of these 6 weeks of VIP, I am already at the halfway mark of the entire

internship. I feel that it is a very enriching 6 weeks working at Everfeed Technology Pte

Ltd. For a start, I have learnt a lot about the ESD industry, the different measurement

equipment (CPM, multimeter, EMeye, etc), the current standards (IEC, JEDEC, ANSI),

the current industry practices and how important it is for engineering and manufacturing

companies to control and limit electrostatic discharge.

The experience is of course not without any challenges, with the limited amount of

resources I have and my brief understanding of ESD as of now, I have to work even

harder to fully understand and effectively interpret the concepts in the presentation.

With my primary role to help with the upcoming symposium’s presentation and to market

/ publicise about the ESD symposium, I wish that for the next 6 weeks, I can achieve

better results and make the entire internship a more fruitful experience.
