Dragon Boat Festival Notices

Tomorrow (June 12) is Chinese traditional Dragon Boat Festival (the 5th day of May, according to Chinese Lunar Calendar). We will close to celebrate that holiday and resume on June 13 (Thursday). Samples, or volume production of FPC, Rigid-flex will be temporary hold on and lead time will be one day postponed accordingly.

Each time seemed the Dragon Boat Festival will comes with rain, and the same for this year. It cools down the temperature and cool for holiday.  Do you like Zongzi (a type of dumpling, with rice packed in green leaf)? Will you go to have a look at the Dragon Boat Race?

Wish everybody has a happy holiday! 🙂

Updated: Here are comments from some of our customers in US:

” It was a very bad and I certainly hope this craziness stops * it is heartless”- by Dorothy

“Thanks for your well wishes and prayer for my family and all the families that were devastated by gross act of evil. None of this affected my family personally but it was heartfelt by us all here in America and abroad.” by Tony

“We were also in shock with that news. It is hard to understand how could anybody make the decision to shoot any people, but it is harder how could anybody decided to kill such innocent people like those children that died in this tragedy.”  by Doug

“This was something unexpected and this leads us to reflect and analyze the care we we’re putting our children. I believe that this event should not have happened, but time does not return and we must learn from this hard lesson.” By Nubia

“Keep praying for God’s comfort and strength for the family who lost their loved ones.” by Soni

Normal Thickness for 2Layers Flex Circuit (Adhesiveless)

Following up with the last article , here we’d like to share thickness for 2L flex circuit if using adhesiveless material.

2L FPC Flex circuit thickness (adhesiveless)

2L FPC Flex circuit thickness (adhesiveless)

2L FPC thickness using adhesiveless material

We also have other special material, such as 1mil Polyimide + 2OZ (70um) copper adhesiveless, (from Dupont). If you need more information, please contact us.

Normal Thickness for 2Layers Flex Circuit (Adhesive)

Different from rigid FR4 PCB, there’re three basic layers for flexible circuits, and various thickness of each maybe used, so people new to that area will be confused to choose a suitable thickness.

Here are four normal thickness for 2 layers (Double sided) flex circuit, and we hope it’ll be useful for the green hand:-)

2L FPC Thickness

2L FPC Thickness

As you can see, there’re adhesive in base for each four basic thickness of 2L (double sided) flex circuits, if you need more thin, then you can use adhesiveless material, and final thickness will be thinner even you use the same copper and Polyimide thickness. Please see next article (to be continued…)

Solderability Test Experiment

As is well known, solderability is very important for the printed circuit boards, we must do solderability test of each batch PCB we made. In this way we can inspect the weldability of the PCB before we go ahead the assembly process, much helpful for SMT.

Today we are going to discuss the solderability test experiment. In order to explain it more clear, we now do a simple solderability test and show you all the steps.

1. Take a small solder pot, plug in the power, turn on the switch and heat the solder pot to a certain high temperature(about 8 minutes).

2. Put a tin bar to the solder pot, then you can see the tin bar is begin to melting, slowly into liquid tin, then more and more.
3. After few minutes, there will be enough melting liquid tin in the solder pot to do this test.
4.Use a tweezers to pick up a PCB circuit, first clean the PCB with rubbing alcohol. Because the unclear surface or the oxidation of the PCB will affect the test result.
5. This is the key step of this test, put the PCB into the solder pot, depth about 2 mm,time 4-5 seconds is ok. Then you can see the tin will go into the hole of the PCB.
6. Take out the PCB from the solder pot and put it into the cold water. After few seconds, you can see the experimental effect.

This solderability test is very simple and easy. We can see the results very soon. Our Best Technology did solderability of every batch PCB we made, and we also supply our customers with the solderability test report and the test samples.

Happy National Days

With the weather is getting cold , now we really greeted the Autumn, a season of harvest and happy. In this enjoyable autumn., we also willl usher in the most important festival in China- National Day.

The National Day of the China is celebrated every year on October 1. It is a public holiday in China. Usually people will have a 7 days holiday to celebrate the national day, called “Golden Week”.

National Days are festivals which can stand for independent countries. In the world, countries establish their Notional days on the basis of different ways. Therefore, the names and celebrations of National days in different countries are various. In China, The most significative activity in National Day is The Big Parade in Beijing, Parade Is a ceremony to review the armed forces.

This day is a day of national celebration. Most people will go travel on this holiday, especially to visit the “Red” tourist sites. People also can enjoy kinds of evening party.

On this national day of prayer and remembrance, we ask almighty God to watch over our nation, and grant us patience and happyness!

Our Best Technology will have a 4 days holiday from tomorrow (Oct 1) to Oct 4 to celebrate the National Day, and reopen on Oct 5. Hope everyone can enjoy this holiday and have a good rest.

Happy National Day! Best Wishes To Our Great Motherland May our country become prosperous and strong!

Happy Mid-autumn Day!

Time flies! Now we ushered in the 2011 Mid-Autumn festival.

Mid-autumn Day is one of the import traditional Chinese festivals, falls on the fifteenth day of the eighth lunar month. On that night the moon is brighter and fuller than any other night. In China, Mid-autumn Day is a time for family reunions.

In ancient China, poets considered the moon as a symbol of brightness, purity, and goodness. They wrote many beautiful poems about the moon. The most popular one was a story about a lady on the moon. She flew to the moon and lived in the Moon Palace.

On Mid-autumn Day, almost everyone gets together with his or her family, eating mooncakes, chatting and watching the moon. Mooncake, whose round shape symbolizes both the fullness of the moon and family togetherness. There are many kinds of mooncakes. They are small round cakes with meat, nuts or something sweet inside . eating mooncakes has been our custom.

The Moon Festivals is one of three major Chinese holidays, along with the Spring and Dragon Boat Festival .On that day, families get together,so we call this day getting together. This is Mid-autumn Day. I love it very much.

Our Best Technology we will have a three day holiday(from Sep 10 to Sep 12) to celebrate the Mid-autumn Day and will reopen on Sep 13. Best Technology wish you all have a happy Mid-Autumn festival! Enjoy the beautiful life together with your family forever.
