The status quo of Chinese society under Coronavirus spreading

This is another test for China and the world community after SARS. At this moment, any slamming, taunting, fanning, and gloating are all manifestations of lack of humanity. The virus does not recognize the country, nation, race, rich or poor. There is no difference in virus transmission.

China’s powerful system and the effective measures it has taken to prevent and control novel coronavirus-related pneumonia are rarely seen in the world, Director-General of the United Nations’ World Health Organization Tedros Adhanom Ghebreyesus said on Tuesday.

Ghebreyesus made the remarks while meeting with State Councilor and Foreign Minister Wang Yi in Beijing.

The WHO and the international community highly appreciates, and fully affirms the decisive measures the Chinese government has taken to deal with the outbreak and also thank China for its tremendous efforts to curb the spread of the contagion, he said.

China set a record in identifying the pathogen in a short time following the outbreak of the contagious disease, Ghebreyesus said, and he praised the country’s timely sharing of the virus’ DNA information with the WHO and other countries.

WHO meeting with China leaders

I don’t know the source of the so-called news of many foreign friends. As a Chinese, I saw the initial panic, and I also saw the current stability.

In response to the GVM’s call, the school has delayed the start of school, and most companies have extended the Spring Festival holiday from original Feb 2nd to Feb 9th and resume on Feb 10th. This is not a sign of lack of confidence in controlling the virus, it is one of the measures to put people’s lives first.

Everyone knows that this is the most effective way to control the spread of the virus.

I went to supermarkets, fruit shops, etc., and there was no snap-up like it was fabricated by some media. Prices have not skyrocketed. The price department is also strictly controlling the prices of daily necessities to protect people’s daily lives.

Relevant departments have made the unified deployment of some protective supplies such as masks to ensure timely and adequate supply. Which country can make such an appropriate response in the first place?

It’s really boring to stay at home every day, but who wants to joke with life? As someone who is very busy working every day, having more time to spend with his family may also be a good thing. After all, too many people complain that the Spring Festival holiday in just a few days is not long enough.

The internet is well developed. Although I can’t meet my relatives, friends, colleagues to celebrate the Spring Festival, isn’t it convenient for video chat, using WetChat of Facetime for people around the word? Why not give up the temporary joy in exchange for the safety of life?

We are very grateful to the medical staff, community service staff, and social service staff who gave up their holidays and took great risks in helping patients, maintaining social stability and creating a more secure environment.

I am grateful for living in such a country. I believe that every Chinese thinks so.

In such a severe situation, in order to eliminate the virus as quickly as possible and ensure the safety of people’s lives, any measures are reasonable.

Every Chinese should understand and understand. 

People of all countries in the world who have experienced various natural and man-made disasters should marvel at China’s timely and effective measures.

As an international trade practitioner, I have sincerely explained to each of my customers our current status. We don’t need to whitewash or conceal anything, because we have done our best to do a good job.

I believe that the Chinese people will be able to eliminate the disease as soon as possible. Because we eliminated more severe SARS than this time in 2003, didn’t we?

Here everyone in Best Technology in China was in good health condition, and our office & facility will be opened on Feb 10th. During that period, our sales reps. will try to reply the email ASAP and thanks for the caring from all of our customers around the word! Much appreciated!

How to Improve Reliability & Flexibility in an 8 Layer Stackup Flex PCB?

When designing a flex PCB stackup, you may face some restrictions in enhancing the reliability of the board. Today, we will discuss the ways to improve the reliability of a board by increasing the flexibility and improving design considerations of a multilayer PCB stackup. These steps can be implemented for PCB stackup designs as seen in 8 layer flex PCBs.

Improve Flexibility by Reducing Overall Thickness

All or some of the below mentioned steps can be executed to lower the overall thickness of the PCB. A thinner PCB stackup will allow it to be more flexible.

1.Reduce the base copper weight.

2.Reduce the adhesive thickness.

3.Reduce the dielectric material thickness.

4.Using adhesiveless base materials can reduce the thickness of the substrate by 1-2 mils, which is almost 25-50μm.

5.Make use of selective plating to avoid copper plating the conductors.

Improve Reliability by Reinforcing the PCB

Here, the boards, components, and the layout should be designed to deliver a robust structure that can withstand flexing.

1.The weight on both sides of the PCB should be equal. This includes the weight of the conductors and the material.

2.The conductors on different layers of a PCB should not be placed on top of each other. Instead, they should be placed in a staggered pattern.

3.Conductor thickness should always be constant in and near the bend areas.

4.There should be no plated-through holes in the bend areas.

5.There should be no discontinuities near the bend.

6.Traditional copper can be proved to reduce the flexibility of a PCB. Opt for screened-on coatings like silver epoxy.

7.For slits in the circuit, reliefs or tear stops need to be built into the PCB.

Tight tolerances will have to be put in place to ensure that your stacked up PCB can provide flexibility as well as reliability. Several of the above-mentioned steps can easily be incorporated in the designing process itself. Your PCB manufacturer should be able to help you with the most appropriate improvements for your application.
