What does 5G mean to the PCB manufacturing world?

Do you know 5G?
And what does 5G effect with manufacture industry, especial PCB manufacture industry.
This post Angel want to discuss some topic about 5G device.
If you have any question about PCB of 5G device, please do not hesitate to contact us.
Here we go.

What does 5G mean to the PCB manufacturing world

The history of 5G

The analogy I understand best for mobile communications is this:

1G = analog (voice only)
2G = digital (includes text and pictures)
3G = video calling and data
4G = internet and video streaming
5G = everything connected to everything (4G on mega steroids and 1000x faster)

In one word, The best way to understand what 5G is about is to understand all the other Gs.

What does 5G mean to the PCB manufacturing world?

5G needs to exist in full measure for truly autonomous cars and trucks to become a reality (or at least a safe reality—think about a self-driving semi on the road behind or beside you). In fact, several communications companies are planning on launching 5G networks later this year. Are we ready? Can we make the PCBs they will need? What does this mean to us in the PCB manufacturing world?

That’s right, building boards is not going to get any easier. And, as we’ve said before, if you aren’t doing HDI and RF now, you will be…or you simply may not be.
Focusing on all parts of the laminate as well as design and most importantly, understanding and specifying the material properties needed as opposed to a specific material itself.

Top 5 Advantages and Features of Metal Core Printed Circuit Board

This post let’s discuss Top 5 Advantages and Features of Metal Core Printed Circuit Board (MCPCB).
Top 5 Advantages and Features of Metal Core Printed Circuit Board

MCPCB Can easily be used for Surface Mount Technology (SMT)

Surface-mount technology (SMT) is a method for producing electronic circuits in which the components are mounted or placed directly onto the surface of printed circuit boards (PCBs).
A huge majority of today’s electronics are manufactured with SMT, or surface mount technology. Devices and products that use SMT have a large number of advantages over traditionally routed circuits; these devices are known as SMDs, or surface mount devices. These advantages have ensured that SMT has dominated the PCB world since its conception.

SMT has almost total domination of PCB creation process. Not only are they more efficient to produce, and smaller to transport, these little devices are also highly efficient. It is easy to see why PCB production has moved on from the wired through-hole method.

Assists with thermal diffusion of heat from LEDs

Heat pipe embedded Metal Core Printed Circuit Board (MCPCB). Today new heat pipe embedded MCPCBs efficiently spread heat from LED devices, providing a reduction of 45% in thermal resistance compared to pure aluminum MCPCBs.
In most general lighting applications, the heat must be dissipated through natural convection heat sinks (where radiation may play a significant role) to meet acoustic noise restrictions. However, the thermal management requirements of emerging high intensity LED lighting products often exceed the practical limits of these passive cooling strategies. Integrating heat pipes, HiK™ plates, or vapor chambers with the heat sink can reduce the LED temperatures, and allow current heat sinks to handle higher heat fluxes.

Applications of MCPCBs in the LED industry

There are several occasions or you may say applications in the LED industry, which make use of printed circuit boards. The following are some key application areas of PCBs in the said industry:
Street Lighting
Elevator Lighting
Aircraft Running Lights
Operating Room Direct Lighting
Traffic and Signal Lighting
Highway Tunnel Lighting
Solar Power Products
Security Lights
Flood Lights

Reduces product operating temperatures, increases the power density and reliability, and helps to extended product life

The convenience of both a heat sink, as well as PCB is achieved. This means that you not only get the thermal characteristics of a heat sink, but also a cost-effective and compact design of a PCB.

Smaller footprint, lower hardware and assembly costs

They help achieve two purposes in a single go:
Act as a heat sink for the design
Allows different components of the LED design to be interconnected

Replaces fragile ceramic based pcbs, and has better mechanical durability

These PCBs are capable of handling high temperatures and help in higher levels of thermal heat transfer. This prevents the circuit to get heated and damage the LEDs mounted on it.

How Automotive PCB board meet TS 16949 Standard in 2018?

This post we are going to discuss how Automotive PCB board meet TS 16949 Standard issues.
Related TS 16949 Standard post:

If you are building for the automotive industry (or want to be), you will eventually need to be certified to the IATF16949 standard. It is extremely important to understand the requirements, which can often be daunting and confusing.
If you have any Automotive PCB board or Automotive PCB board standard question, please email us at smith@4mcpcb.com

Why Automotive PCB board need over and above the ISO requires?

In terms of quality management systems, here is my ranking of the international standards as measured by requirements and the level of discipline required to meet them. In order of increasing degree of difficulty: ISO9001, ISO13485, AS9100, IATF 16949. What follows is an outline of some of the major requirements that are over and above what ISO requires.

All Automotive PCB Boards Must Meet Customer-Specific Requirements

This requirement specifically addresses the need to evaluate your customer-specific requirements and include them where applicable in the quality management system. This means that a process is needed to evaluate each customer’s “customer-specific requirements” and integrate them into your QMS.

The Safety of Automotive PCB Boards

These are enhanced requirements that re-quire a process for proactive awareness and mitigation of current and emerging product and process safety issues facing the automotive industry. This includes a focus on statutory and regulatory requirements to identify and control product-safety-related characteristics during design (if applicable) and manufacturing including defining responsibilities, escala-tion processes, reaction plans.

Rigid-flexible PCBs Design Cost Introduce

Rigid-flex PCB Designer Introduce Cost

We have introduced Rigid-flex PCB Cost comparison of design.
Most of the time we just consider the price of Rigid-flexible PCBs design.
This post we will discuss how Rigid-flex PCB Designers thoughts.
Rigid-flexible PCBs Design Cost Introduce

Why Rigid-flexible PCBs design always be more expensive?

You are merging multiple boards into one design, only one design is needed with a rigid flex.
Often with a rigid PCB/cable solution, multiple PCB designs and multiple cable assembly designs are required.
The costs for generating each design should be calculated and included when doing a cost comparison of both solutions.

Top 6 Factors Related Rigid-flex PCB Design Process should Consider

  1. Communicate with the fabricator! If you have any questions, please contact rigid-flex PCB experts
  2. Qualify the fabricator’s capability to build the planned rigid-flex design.
  3. Involve the fabricator as early as possible in the design process.
  4. Collaborate so the design’s layer stack matches the fabricator’s processes.
  5. Use IPC-2223 as the common point of reference with the fabricator. Otherwise, communication in the form of documentation can cause errors and misunderstandings resulting in costly delays.
  6. Graduate from delivering Gerber files to the fabricator. Instead, deliver files in ODB++ (v7.0 or later) or in a format that meets IPC-2581 because either format identifies specific layer types for clear documentation.

If you have any questions about Rigid-flexible PCBs design cost, please do not hesitate to ask 4MCPCB.com experts.

Simple discussion: the advantage of rigid-flexible PCB

Simple Introduce the advantage of rigid-flexible PCB

We have introduced many advantages of rigid-flexible PCB.
Today we just simply introduce again.
Simple Introduce the advantage of rigid-flexible PCB
The transition to a rigid-flex design from the traditional approach of using cable assemblies to join two or more PCB’s has obvious benefits – space, weight, packaging, reliability and increased current carrying capabilities

Are Rigid-flexible PCBs always be more expensive?

Many times the perception that rigid-flex is a high-cost solution, causes designers and engineers to hesitate.

We are often asked for our thoughts on how to compare the cost of a rigid-flex design with the more commonly used rigid PCB and cable technology.

The answer is more complicated than simply comparing the bare board cost of the rigid PCB to the rigid flex.

The rigid-flex will almost always be more expensive.

Reviewing the overall total cost of assembly for both approaches provides a more accurate comparison.

If you have any questions about advantages of rigid-flexible PCB, please do not hesitate to ask 4MCPCB.com experts.

High-speed PCB market share become more bigger

The reason why introduce high-speed PCB market share

We have discuss many posts about led PCB manufacturers or metal core PCB.
High-speed PCBs are very difference PCB type.
It’s have more complex than single-sided PCB board, and have high-speed PCB market share become more bigger.
That’s the reason why we have talk this topic.

China high-speed PCB market introduce

China’s high-frequency, high-speed PCB market development is closely related to the global market. It is, and will always be, an important part of global electronics manufacturing and consumption. Shengyi Technology has been planning for the high-frequency, high-speed market for 15 years. Back then, we were still in the technology accumulating phase. We continued to keep up with global PCB technology trends and technology. Of course, high-frequency, high-speed PCB market is only one part of what we are tracking.

The ever-changing market in recent years has proved that only independent R&D with constant improvements in process, technology, quality, business management and continuous innovation will pay out. We admit that there was some distance between Chinese and Japan and U.S. manufacturers, but it has been shrinking in the past 10 years. Today, this distance is little; in some technology field and products, we have surpassed Japanese and U.S. manufacturers, posing a serious threat to their once dominant market.

Market demand is constantly changing, product application continues to refine, along with new processing, and supporting technology innovations will make us change. This is just the reason we are still insisting on independent R&D and innovation. We keep track of any market changes. We value every single customer feedback of new demands. We also thank Japanese and U.S. manufacturers who are competing with us and set obstacles for us. The world is always changing and developing; the only thing that is constant is change, and China’s high-frequency, high-speed PCB market is also changing.

Gu: In this area, what is the main advantage of Chinese companies? Will this advantage provide global competitiveness?

Lin: The PCB and CCL market is an area where international competition takes place. To some extent, since the reform and opening policy, China’s domestic market has grown to the largest electronics manufacturing and consumer market in the world, with a huge market demand. Therefore, the biggest advantage of Chinese industry is overall industry chain that was developed over decades of technology accumulation and market cultivation.

The Chinese electronics industry is well experienced in international competition. We have also experienced a number of industry development cycles. The Chinese electronics industry experienced almost 10 years of rapid development after 2000, which is related to the world economy and global semiconductor development trends.

Of course, we are also aware that China’s development in recent years is different from 10 years ago (before 2008). In 2000, the global manufacturing industry, including the electronics industry, was moving to mainland China. Back then, China’s main advantages were a huge market potential, low labor costs and government reform and opening economic policy. Today, the advantages of China’s demographic dividend are disappearing; environmental protection and other policies and regulations have become tighter, although China is still an important growth point of world economy, to the extremely cost sensitive manufacturing industry. Labor costs and regulations will seriously affect the whole Industry, including CCL, PCB and supporting sectors.

In recent years, the entire electronics industry, especially the PCB manufacturing industry, is moving to Southeast Asia and India. The Trump administration also wanted to “bring manufacturing back to the U.S.,” hoping that real economy could support the U.S. economic development. This will have some impact on China’s electronics industry and manufacturing, but mainland China has been the global electronics manufacturing base for 30 years; I am afraid it is not that easy to change.

Mainland China still owns more than 65% of global PCB market share in 2016, and maintains a growth rate above 7.5%. In terms of high-frequency, high-speed, China’s biggest advantage is that Chinese companies have been breaking through in some cutting-edge technology and industry, challenging Europe, U.S., Japan and other developed countries which are dominant in technology and market for decades. We will stick to independent R&D, domestic production, use domestic supply and provide our customers with professional, high-quality technical support and supporting services. China is actively developing a semiconductor industry, according to China’s strategic policy. Dominant in semiconductor industry dominates the entire electronics industry.

In this context, Chinese companies are actively doing industrial transformation and upgrading and have achieved some results. They are going upward from the low value-added competition. In the future, Chinese companies will continue to maintain their leading position in top-level global manufacturing competition. Among them, of course, is high-frequency, high-speed.

Leading Chinese High-Frequency circuit board raw material

Why we discuss Chinese High-Frequency circuit board raw material

This post will discuss leading Chinese High-Frequency circuit board raw material.
There were so many High-Frequency circuit board manufacturers in China, and most of them will announce that top brand and high quality.
We don;t want to discuss about who is the top or No.1 ranking High-Frequency circuit board manufacturers.
On the other hand, we are going to talk about Chinese High-Frequency circuit board raw material situation.
If you have have difference opinion about Chinese High-Frequency circuit board raw material, please do not hesitate to contact 4MCPCB.com.

High-Frequency circuit boards are the Trends

The advent of 5G in 2020 and future ICT technology trends will make data storage, transmission and computing experience explosive growth. The demand for high-speed, high-frequency material will also grow. For high-frequency material, the main application will be wireless transmission and reception that contains a huge amount of data, and network signal coverage.

Base-station wireless signal transmitting and receiving frequency has been increased from the old, sub-3 GHz to 6 GHz range. To meet the demand of point-to-point transmission, the frequency of supporting coverage network has reached 28 GHz and 39 GHz or even higher into the millimeter wave frequency band. Automotive radar application has reached 76−81 GHz millimeter wave band. The main challenge in high-frequency application R&D is to achieve stability, ultra-low loss. Through strict process control and a quality assurance system, we can ensure product consistency. In the meantime, in multilayer board design, we have to take into account the substrate thermal conductivity and processability.

Today, more and more substrate manufacturers are entering the high-speed material sector; the competition is getting more intense. There are so many products in the market, but good quality high-speed product is not that simple. Because the application is very different for high-speed, high-frequency material, the adhesive technology, performance design, manufacturing process, quality control, testing methods and supply chain management are quite different from traditional FR-4 products.

The traditional way of thinking in R&D and product management is a model that should be avoided. From a product development point of view, to develop product that meets market demand is not an easy task; it reqiures technical capability, continuous innovation, capital investment from the company, and a strong market validation and development team. From a marketing point of view, the one who has the most advanced technology will dominate market opportunities.

The biggest challenges we have encountered in high-speed, high-frequency material R&D and manufacturing are the formulation technology in product technology, such as product cost design; performance design; corresponding product manufacturing process technology; quality management. Additionally, high-frequency, high-speed material will ask for much better performance from supply chain management in the future. How to optimize and integrate supply chain resources to achieve mutual growth will also be an important issue for high-frequency, high-speed material.

Do you know the CAD files of the flexible circuit board

What’s CAD files of the flexible circuit board?

If you don’t know CAD files of flexible circuit boards, you have to read this post.
First of all, we must know why we have to create CAD files of the flexible circuit board.
The aim I to define and subsequently manufacture a custom flexible circuit board.

Then back to the process of flexible circuit board.

As we know there were so many PCB manufacture processes, and each process has one special CAD file of the flexible circuit board.
So when you ask a PCB design company, you should ask them finish the CAD files of the flexible circuit board must include several parts below.
1, PCB drill file
2, PCB rount file
3, each software-controlled machine to perform its required process step.

The CAD files of the flexible circuit board differ from design Gerber

Usually our customers will send the Gerber file to us.
By the way it’s very different with the CAD files.
Because the type of data a circuit supplier receives from a customer can query widely.
Our RD will translate the Gerber file to CAD file that can use for our PCB manufacture equipment.
This is a very complex process for most green hand flexible circuit board design.

How to transfer the Gerber file to CAD file of the flexible circuit board?

Most of the time, the CAD files contain a complete set of data to manufacture a one-up part.
This means you can use this CAD file to finish all manufactures flexible circuit board process.
Usually this type CAD file of the flexible circuit board requires high end PCB manufacture equipment.
So, ONE CAD file of flexible circuit board solution cannot suit for small plants.
