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
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
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.
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
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
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!
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.
A six layer Rigid-Flex PCBs, as the name implies, is manufactured using six conductive copper layers. However, do you know the materials used for constructing 6 layer rigid-flex PCB? Now let me lift the veil for you.
6 layers rigid flex pcb
Base Materials – The most commonly used base materials for manufacturing 6 layer rigid-flex PCB is woven fiberglass impregnated with epoxy resin. The use of cured epoxy makes the board more rigid. Manufacturers also prefer Polyimide rather than normal epoxy resin to ensure extreme reliability in complicated applications. Polyimide is chosen due to their extreme flexibility, toughness, and heat resistance properties. Polyester (PET) is also another material of choice for the PCB fabrication. Manufacturers often choose the most suitable materials according to the specific application requirements of customers.
Films – Manufacturers prefer PET films for producing 6 layers rigid-flex PCB due to their corrosion and heat resistance properties. The thickness of PET films used for the PCB manufacturing vary from 1/3 mil to 3 mils.
Conductors – Copper is the most preferred conductor of choice for making 6 layer rigid-flex PCB and various types of copper are used according to the specific application requirements. Annealed copper is used when repeated creasing or movement of the flex circuit is demanded.
6 layers rigid flex PCB
Adhesives – The use of high quality adhesive is crucial to make a fine bonding between the conductor and films. Acrylic or epoxy based adhesives are the most commonly used adhesives to achieve a firm bonding, while silicones, hot-melt glues, and epoxy resins can also be used for bonding.
Manufacturers who are very familiar with the properties of the aforementioned materials can conduct their mechanical design, evaluation and testing of the PCBs better. Therefore, a manufacturer who fabricates 6 layers rigid-flex PCB for the automobile industry must quite know the moisture, chemical, shock & vibration resistance properties of the materials used in the construction. This contributes to enhancing the durability of PCBs in the case of industrial specific applications.

Rigid PCBs typically cost less than flex circuits as flex circuits may eliminate the need for components such as connectors, wire harnesses, and other circuit boards. By removing these components from a design, material cost, labor and assembly cost are all reduced.
Many electronic devices (laptop and desktop computers, audio keyboards, solid-state drives, flat-screen TVs and monitors, children’s toys, and various electronic gadgets) employ rigid PCBs instead of flexible PCBs. However, flex circuits may be found in ultra-compact and/or high-performance devices, including GPS units, tablet PCs, smart phones, cameras, and wearables. Flex circuit makes installation get much easier.

Wearable technology is evolving at a breakneck speed, with the help of advances in flexible printed circuit boards. One of the biggest challenges researchers and manufacturers face when devising wearable technology is creating materials that can flex and stretch while also maintaining conductivity and connections with the different circuits.
FPC in the wearable
Developing just the right materials is a crucial piece in the future of wearable technology.
What Materials Work Best with Wearable Technology?
Wearable technology is a big category and includes everything from patches that can be layered onto skin to coats, shirts, and even sports bras. Each iteration of wearable technology offers unique challenges when finding the right materials.
Graphene is a popular material choice, because it is an excellent conductor of electricity and also very flexible. Graphene offers an important alternative to wearables that rely on rigid components that can’t flex well. Researchers are actively experimenting with ways to blend graphene-based inks into cotton cloth.
Another option is the thermoplastic polyurethane, a highly adaptable plastic material. Already, a German company is using polyurethane to develop wearable skin patches that are breathable and hypoallergenic. Another thermoplastic polymere called polyethylene terephthalate (PET) offers excellent transparency, good flexibility, and is easy to fabricate.
The latest material innovations has been the development of soft silicone elastomers. Not only do these materials offer great flexibility, but they are prized for their ability to conform to a wide variety of shapes and textures. This puts them at the forefront of stretchable, wearable sensors. Some of the top soft silicone elastomers are: EcoFlex®, DragonSkin®, and Silbione®.
The field of wearable technology materials is advancing at breakneck speed. Here at Best Technology, we are keeping on top of these trends so that we can continue providing the most advanced flexible printed circuit boards to our customers.
Most of today’s flex PCB manufacturing process begins with a prototype production. There are several advantages of building a working model of the flex circuit before attempting the mass production of these boards. Building a prototype not only helps to test the board’s function but also aids in improving it as per the requirement. Additionally, prototype creation helps in detecting errors at the earliest, and decide upon the final design and other specifications of the board. Since prototype creation plays such a decisive role, it must be executed by an experienced service provider. But, how to find an experienced service provider? Do not worry, you can evaluate the competencies of flex PCB prototype making by asking a few questions such as:
1.How long have you been providing Flex PCB prototypes to the customers: Although the question seems basic, it helps to evaluate the total experience of the manufacturer. A PCB manufacturer with several years of experience will be certainly equipped and professional enough to understand your prototype requirements than a startup.
2.How long will you take to complete the prototype making from the order accepted date? Although the turnaround time varies as per the capabilities of the manufacturer, the manufacturer must be able to create Flex PCB Prototypes in 24 to 48 hours or within a week’s team. More than the said time frame is not usually acceptable when it comes to prototype creation.
3.What are the quality standards you implement to get the prototype right and functional? Again, standard and certification compliance varies across the industry. Since there are several international standards formulated to ensure the boards quality, you must know the quality standards followed by the chosen manufacturer.
4.Do you own a well-equipped manufacturing facility to proceed with the approved prototypes for mass production? There are some PCB production manufacturers that are specifically functioning to meet the prototype demands of the customers, and not in mass production. Lack of cutting-edge production facilities, advanced equipment, and man power are amongst a few reasons why such production houses limit their service to only prototyping. Hence, you must ensure the extent of their service.
5.What methods do you use to assure quality? It is inevitable to have the same level of quality checks throughout every stage of the flex PCB prototypes production. Hence, while choosing a PCB production manufacturer, it is extremely significant to ensure that they are performing the inspection stringently utilizing the best of techniques such as visual inspection, X-ray inspection, and Automated Optical Inspection.
Flex PCB prototypes can be extremely helpful as they help both the manufacturers and customers to check the board against various parameters before the mass production.

In the electronics industry, the name of the game is lighter and smaller. Consumers want sleek, beautifully designed computers and gadgets that still pack a big computing wallop. That is to say, for designers, at least, space is money.
If you can make your product smaller and less bulky than the competition, you will gain the market advantage. Flex printed circuits boards (aka flexible circuits or flexible pcb) are designed to give you all the space you need to create innovative new product designs.
Now let me talk about the trouble with Rigid Printed Circuit Boards
If you’ve ever had to work with rigid printed circuit boards before, you know how much of a nightmare they can be. You have to find space for them and work the rest of the components around them. Flex printed circuit boards give you back control over your design. Because they can flex, you can fit them into smaller spaces, which frees up space for more components, that can make your product more powerful, more efficient, or both. They fold, twist, and roll, making it easy to find a spot for them. This also gives you the opportunity to place other parts in a better order for the most efficient sub-assembly possible. Better part placement refers to less energy waste, a longer battery life, a more solid overall configuration, and a better operating product. It also means you have control over how you map out the inner workings of your product for optimum setup.
In the fierce electronics industry, even a slightly better assembly can put you ahead of your competition and turn your product into a bestseller, while they get left in the dust.
Flex PCBs also weigh less. Even shaving off a few ounces on your product could make a noticeable difference that will make it easier for your customers to use it, wear it, and carry it. The more they want to interact with your device, the more hooked they’ll become.
