PCB UV Board Construction

My project student selalu tanya macam mana nak guna developer and etching printed circuit board (PCB). The things is they all malas nak mencari. Tak tahu la nak marah cam mana lagi. So students out there yang tengah membaca ni, rajin2 juga la buka website yang berilmiah skit untuk upgrade diri kita yang lemah ini.

So, I would like to share cara2 untuk expose, developer and etching.

------------------------------------------------------------------------------------------------------------

Today, i decided to make PCB board using UV (Ultra Violet) method for sharing the knowledge on the procedures & process of UV PCB construction. Here are some of pictures with brief explanation.

Step 1: Print a circuit on laminate paper

Step 2: Buy a Kinsten Coated PCB - GS1015 for single layer and the manual instruction inside the product.

Step 3: Attach a circuit together with Kinsten Coated PCB and expose it with light (photoresis) using UV machine around 90 to 120 second.

Step 4 : A picture of PCB after photoresis process. Remove a circuit from PCB and you can use again the same laminate for other PCB.

Step 5 : Quickly bath a circuit with water and developer then shake it until the unwanted layer remove from the PCB.

Figure A : Picture sample of developer. You can used other product you like.

Step 6 : After wash a PCB, bath the PCB with ferrite chloride & hot water then shake the PCB again until the second unwanted layer removed from the PCB.

Figure B : Picture sample of ferrite chloride product. Caution! You are deal with dangerous chemical (developer & ferrite chloride). Wash you hand after using it. Please use a glove if possible and dispose the chemical properly.

Step 7 : Lastly, brush your circuit and see the different. Now, you can cut any PCB size and drill the PCB for soldering purpose. That's all :)

The Billionaire vs Tao Kae Noi

Sambil menjaga sQ yang tengah demam last Saturday, Mr Hubby and I watched this Thailand movie aired on ABO. Kelakar juga cerita ni. This story was about a young boy at age 18 ingin menjadi usahawan muda untuk membayar semula hutang ayahnya pada bank sebanyak 40 million Baht. 

At first, this guy nama Top Ittipat, niaga buah berangan. Banyak juga dugaan dan cabaran yang harus dia tempuh at a very young age. Then he got inspired by eating his girlfriend's seaweed. So dia cadang nak goreng then belajar how to pack in order to maintain kerangguppan seaweed yang lama.

Tetiba one of the scene ada mention nama product seaweed tersebut which is Tao Kae Noi. Tengok semula info then baru perasan this movie was based on true story. Lagi la Mr Hubby and I excited nak tengok this movie sampai habis coz we love eating this snack.

So, tak nak story banyak, better you guys check out this movie for yourself.

Top Ittipat himself and his most famous seaweed snack

Now he is 26 years old, earning 800 million Baht per year with his own seaweed farm at Korea.

Resistor Color Wheel

Resistor is the most basic component that all electrical engineering student must know. But when I teach semester 3 students, they still don't know what color for resistor value.
To outcome this matter, I forced each and every one to make this Resistor Color Wheel. By this, I do hope they will remember the color coding.

During my search for this idea, I came across a new way to memorize the color code. During my studies, I was thought with this phrase: Haji Pak Mat Jiran Kita Hidup Berkebun Ubi Kayu Putih

But now, there are a new phrase which is up to date: Hanya Pada Mu Jiwa Ku Hancur Berderai Untuk Kekasih Pertama

Projek Memikat Suami

I manage to read this book last couples weeks ago. This book was recommended by my colleague Hasnina. Memang dah lama giler tak baca novel. Last book was the Twillight. All 4 books I read. Novel local jarang baca sebab cerita dia kadang2 terlalu perfect watak2 yang ditulis. Tapi why not give it a twist in live. 

For me, it a good story which could give tips to newly weds on how you should take care of your hubby. So I include sekali sinopsis cerita ini. Enjoy!

Cziplee & Frixion Pen

My love at first sight to this stationary store and frixion pen starts when Mr Hubby bought this erase pen to our daughter. Pen ni senang, kalau salah boleh padam-padam. Why I love this stationary store, sebab almost what i want semua ada kat kedai ni.

This store is located at Bangsar, Jalan Telawi 4. They even have branch at Kajang. Tak sempat nak snap picture sebab too excited nak beli barang.

This is the pen that I was talking about. Here the detail from Pilot:

The erasable Frixion Ball pen is perfect for day dreaming and brainstorming, allowing you to change your mind as often as you like.

Or use it for taking notes in meetings or in class, keeping your diary neat and up-to-date, or for writing birthday cards and invites.

Contrary to other erasable pens in the market, the Frixion Ball has strong and vivid ink colour, does not scratch or damage the paper you are writing on, and allows you to immediately re-write over your correction.

The Pilot Frixion Ball is available in 9 bright colours to match your mood; black, violet, blue, light blue, green, brown, orange, red and pink.

Caution

Do not use the Frixion products when signing legal documents or cheques or for exams and other important writing.
Do not let the Frixion pens or any text written with Frixion ink be exposed to heat as this will cause the ink to turn invisible (this includes prolonged exposure to direct sunlight).
Pens exposed to heat can give the appearance of having run out of ink when in fact the ink is just not visible. If this does happen, place the pen or paper in the freezer for a short period of time for the ink to become visible again.
