After 3 months, finally the internship has come to an end.
Today I got to clear and settle all my things,
Walking to different department to return belongings;
Smock, booties, excess card, badge, locker key, medical card…..

L@sTlly, of CoUrSe.. Photo Taking SeSsioNs…

This pretty mother to be, is my Trainer, Geck Fong .. Anything I don't know, I will refer to her...

AI HWA.... a little elder than my mum... very friendly person..

from Left to Right, its Jason, CS Ng, and Yoke Kheng, we call her Kheng Jie, very experience person in the Q&R lab...

These are trainees from USM, the girls are studying Material Engineering, while that guy is studying Computer Science...

cHiK cHaK.. cHiK cHak.. SmiLeSss… CheeSee…

Many more pictures in my folder.. but having problems uploading it...

“All the BeST… T@ke C@rE..”

Yup, we went to Pizza Hut for my Farewell..
Not really mine,
but together with another 2 trainees
from USM who are leaving next Friday,
We celebrated together.
There were 16 of us, everyone from Failure Analysis & Reliability Lab.
Just a quick farewell, not much time for the “HOO HAA HOO HAA” enjoyment, as its our Friday lunch time, only one hour duration.
Althou its just ONE hour, I spend more of the time walking around the table snapping pictures with my fellow colleagues..

The Supervisor and The Trainees... On the left, Mr. Yeoh Lai Seng, me and the curly hair Chien's supervisor.. On the right, Mr. Jason Ng, the right most girl, Yu Xuan's supervisor...

Memories… freezes.. in pictures..
Happiness… felt .. in heart
We all had fun, talking jokes over lunch …

~~ OH NO..oh no....

GREAT~!!.. socket is here.. but no one knows how to function it… TO achieve your final aim.. u always need to fulfill all contributing factors.. Doing ATE test doesn’t sounds POSITIVE…. Still waiting for the engineers to discover how to use.. mean time also waiting reply from the engineer in US.. Hope to hear GOOD NEWS..

BUT…, only 3 days left….. Mon – Weds….

Miracle happens?? Hmm.. I hope so…

~ Story of a SOCKET...----> Extend ~

Everyone is happy posting , counting down the days left, hours to go on their last day which is today, 25th June, announcing their 12 weeks of Industrial Training finally ended !! in facebook, congratulating each other through SMS, thinking and planning their celebration venue and activity.
I do not share the same feelings as them Because… I AM EXTENDING MY TRAINING til next WEDS.. Do not take me wrong from the expression of the sentence above. I do not mind to extend my training, cause my intention is to learn something extra on my project.
My supervisor wanted to do ATE test on WLCSP, the package unit of my project as a further studies. In production mode, electrical testing is usually performed using a test system. Such a test system is referred to as an automatic (or automated) test equipment, or ATE. The tester performs the electrical testing itself using testing process executed by the tester is controlled by the test program or test software.
So, my supervisor went to ask the Product Engineer to teach me on how to conduct this test. Unfortunately, he told him that they only perform test on wafer form packages but not singulated unit. Hence, my supervisor went to find for testing socket of WLCSP for singulated package. Guess the source where he finally found the socket…??? Its from US !! Wow! So that engineer posted the socket to FAIRCHILD PENANG all the way from US.. Just for my project.. wah.. so honored.. so lucky..
Now it’s the problem of worrying the parcel wont be able to reach here before I end my training.. Parcel from US.. how long that suppose to take? One more week and my training ends… On 22nd June, Tues afternoon, 4 days before my training.. a DHL parcel arrived in Q&R lab…attention to my supervisor, MR LS Yeoh… Is it the WLCSP socket from US? Hmm.. Unwrapping the parcel with curiousity….. aaannndd… YUP, IT IS ! COOL.. I am gonna start on ATE test.. More knowledge on new device.. new process…
SO.. this was why I decided to extend my training.. Isnt it cool that u as a trainee get to learn how to use a device that we do not have in Penang branch.. and needed to lend it from US Headquater? What a opportunity I thought.. So, I extended.

~ The Countdown ~

Everybody posting this in their facebook status recently “ Counting down the remaining days”, “ one more week to go.”.. Everyone is so excited that internship is soon towards the end. Of course, I feel a bit excited about that too.. haha.. I still remember the first week when I first got in my company.. all alone.. knowing nobody in there.. I feel so helpless.. Cnt wait to get out of this place.. full of strangers…
Slowly, get to know ppl around, made new friends., used to waking up, go to work, used to the working environment here.. when things settled down and caught in hand.. its time to say BYE again. No wonder people say 3 months duration for internship is short. I first thought 3 months is long but know I know why its short. Finally, times flies. One more week to go, and internship END.
Today, I have a different thought in my mind. I told myself.. “You like living a student’s life compared to an adult’s working life… but in future.. you will like a trainee’s working life than a permanent employee’s working life, less pressure and responsibilities” So, I will appreciate the remaining days of my internship in Fairchild, gain as much knowledge and experience as I can.. to make use of my internship to the maximum. I am very gladfull people in my work place is friendly, nice, willing to teach and share their knowledge with me.

~ The Line Tour ~

As promised by our Department Head... we trainee got the opportunity to tour down at the production line for us to understand the process of IC packaging. Lucky for me, as it expose me to something out from my project. My project is related to solder bump package and this tour is related to wire bond package. Internship is not about jus completing your project but also some exposure to the industrial. Thats the purpose of internship.

As i know quite a number of people in my batch joined the semiconductor company... Freescale, Infineon,.... and mine - Fairchild. At least, my housemates and I are in semiconductor company for our internship.

I learned and read about the process in slides during my first week of my internship, but I didnt understand well until I went for this tour. Before going in the production floor, the strictly no ESD area, we put on this "bunny suit", booties, and face mask.

The overall process of semicondutor production is as below :

Wafer Fabrication -> Wafer sort -> Dicing -> Die attach -> Wire Bonding -> Molding -> Deflash -> Plating -> Trim & Form -> Testing -> Mark -> Tape & Reel - Boxstock

Interesting and beneficial tour around my company... will jot down in logbook..

~ Curve Tracing ~

Figure on left is the Curve Trace probing station.

Figure on right is the Curve Trace graph viewer.

OKOK. whats next?? CURVE TRACE IS UP NEXT. After finish doing cross section, I proceed with part II of my project. I continued with Curve Tracing. This is to probe the unit sample pin to pin curve tracing to obtain the I-V curve characteristic.

I have to do curve trace on good unit samples and also units which has undergo stress. After that, I will compare the stress unit’s graph to the good unit’s graph to determine which pin has failure.

With such a small unit… 1.0mm x 1.5mm… on the unit, there are 6 solder bumps. This unit call WLCSP, does not use wire bonding for connection instead it uses solder bump to connect to external circuitries. So, I will have to probe pin 1,2,3,5 and 6 with respect to GND and save the graph obtain. TINY TINY little solder bumps on the unit, FINE FINE little probing needles… My eyes see stars…. Again, patience...

But once I get the catch of it.. I am on track… Interesting task.. but I am stil looking forward to understand those characteristics of the graphs for each pin to pin… When is it early breakdown… when is it leakage current.. when it is normal… Hmm..

~ The farewell...

WOW wow wow.. IT had been a long time since I last online.. meaning the last post I upload in my IT blog was ages ago.. Many thing going on in my internship, but never get the chance to share about in here..

Alright I shall start with “farewell” cross section… As you can see the picture above, it’s me grinding the very last unit for this internship project. Wearing glove, putting on the surgical mask.. suppose have to put on safety goggle as well...

When I first started my project, I been doing this grinding and polishing everyday.. repeating the same procedure.. I got BORED doing it.. FED UP doing it… I just cant wait to complete this cross sectional part of my project. Until that day, fianlly, I am doing on the last unit sample, I appreciated every single moment doing the last sample unit of my project, and I find it actually quite fun.

It's just the philosophy of appreciate and enjoy at that current moment else when it becomes a past a history.. Its hard to turn back the time...
