1、 Top 6 PCB Industry Trends and the Manufacturing Challenges They Present


Overview of PCB Prototype Industry Trends


PCB prototypes are slowly becoming pervasive in our daily lives, and this popularity will surely continue in the future. We can all agree that the increase in adoption results from increased consumer demand for smart and functional products. It is what you can observe in almost every industry; aerospace, medical devices, health, retail, and even the military. Here are the trends we expect to see in the coming year.


High Power Boards


Low-power PCB boards are already ubiquitous, and their applications are numerous. But research tells us that there's going to be a thrust towards PCBs with higher power specifications. Do you know the reason for this? The increased usage of solar energy and the anticipated emergence of electric vehicles! Remember that the boards operate at 24V or 48V. PCB prototypes with high power specifications will come to the rescue when mounting components like batteries and panels.


High-Density Interconnect (HDI)


We came up with this technology when the demand for compact products grew. With HDI, we have fewer layers in the PCB stack, and the signals are transmitted at a higher speed. The challenge we can expect in this area is the ability to deal with noise and interference.


PCB Prototypes and Internet of Things


IoT is what enables wireless and swift sharing of data between different components in an ecosystem. IoT is what assures us that our smart home technology and smart cities will come to fruition. One challenge, however, is adhering to several standards and regulations, especially to enforce security.


Flexible PCBs


You know that flex PCBs are slowly taking over, right? Have you read the report that says that 33% of the produced PCBs will all be equipped with flex abilities in a couple of years? Flex boards have an advanced capability, small size, and they are reliable.
Commercial-Off-The-Shelf Components (COTS)

COTS components are inevitable if we are serious about bringing standardization to PCB prototypes used in systems with strict requirements. One area where this application is merely inevitable is in space manufacturing; the components are under immense scrutiny. The fact that the industry is leaning towards commercialization even brings up the need for COTS components.


Component Supply Chain Control


At the beginning of this chapter, we mentioned how the demand has risen. Well, this has also increased the need for advanced security features. We are currently seeing how virtual reality and augmented reality can aid PCB prototypes, and the future is merely exciting.


2、12 Cool Facts about PCBS That You Probably Didn’t Know!

1、Why Are PCBs Green?


You've probably taken a moment to ponder why most PCBs you see have that trademark dark green color. Even if you haven't, it is a fascinating fact that would stimulate your curiosity buds. All right, here's it.

The green color visible to us is the color of the solder mask showing from the glass. There are speculations that green was the regulation standard when the American military used PCBs, and then it just spread naturally. Other theories postulate that green is the color of the original solder mask resin. So, even though the material isn't being used anymore, we're merely following convention by sticking to the color green. However, you should know that in circuits nowadays, the solder mask can take on any color.

One last reason why we haven't changed from green: so far, green works. The color is one reason why engineers can easily see any fault in the traces.

2、Who Invented PCBs?


It is a million-dollar question. We're giving you the answer for free. Paul Eisler is credited with being the father of PCBs. Paul Eisler is an inventor of Austrian descent, and he is the one who developed the first PCB. He did this in 1936 while working on a radio set, although we can trace the development that led to the invention back to the 1890s. After Paul developed the first PCB, it became widely accepted in the 1950s, marking its growth.

3、Look Around You, PCBs are Everywhere


It is a fact that you might not have paid attention to in the past, but we shall open your eyes to this reality. You will see that printed circuit boards are in use almost everywhere you go. You are reading this paragraph from a device that we made using a PCB. If you're not, then you printed it out using a device that contains a PCB. You cannot take five steps without seeing a tool that is underpinned by PCB technology.

Do you know the most exciting fact? This technology has come to stay! There's a very high chance you're within touching distance of a computer system (not necessarily a PC), which uses a PCB. The development of PCBs also leads us to believe that they will not easily surpass them. Research and development are heavily devoted to IoT capabilities, flex PCBs and other features that make the PCB technology futuristic.


4、We Design PCB Using Computer-Aided Software (CAD)


If you've ever sat to wonder how a printed circuit board is designed, this paragraph is all you need. Both the schematic and the layout of a PCB are done via the CAD program. And this is what allows the board design to be tested and checked for functionality. Several tools are used for this purpose, but they all achieve the same primary aim.


5、The Surface Mount Technology


Have you heard about the surface mount technology? Probably not. Nowadays, the term is no longer as popular as it used to be in the 1980s. It was the most common technique employed to manufacture a PCB, and it gained prominence during the period. Before the surface mount technology came along, we had the through-hole method.

The through-hole technique worked like this; the components were attached to the board by inserting the 'lead' of an element into individual holes. As expected, this was slow, and many flaws and defects arose as a result. But with the surface mount technology, the leads were glued onto pads on the surface of the PCB.

6、What You See Are Traces Not Wires


What do you call those lines that run along the surface of the PCB? Well, here's what they are not wires. Maybe you are thinking,
"Most electronic devices transmit energy via wires unless it is a wireless device." Yes, this is correct. However, the PCB is not like most devices/pieces of technology that you're used to.

PCBs stand out in this regard. They use copper traces instead of copper wires to facilitate the flow of electrons. The significant advantage of using a path rather than the wire is that the PCB is much smaller. It is because the traces are flat, and they do not take up much space. Also, at the time, it was beneficial because the use of hints meant that through-hole technology could be used to transfer a hole in the circuit board.


7、pcb prototypes--The Number of Potential Components of PCBs


It is a fun fact that will come in handy; how many components have you imagined in a PCB? Well, unless you thought of a high number (which you didn't), the actual number of members will exceed what you proposed. Surprisingly, every one of these components has its unique properties and features.

Here are some possible components;










Diodes, etc.

There are many more components that can be added; indeed, the potential is enormous.


8. pcb prototypes--Silkscreens


The definition of silkscreen is, in itself, a remarkable fact to know. Can you remember those white etchings that you notice on the PCB solder mask? Yes, that's what we refer to as a silkscreen. It is used to identify which particular component we have and contains some other PCB information. Texts and associated information are printed using silkscreen print, which is the reason for the name. However, in recent times, we have seen printing done using digital ink-jet printers. Cool, right?

9、pcb prototypes--You Can Personalize Your PCB Completely


Some companies give you the option of making a PCB that is specially customized to your taste. It means that they suit the specific specifications that you have in mind. Here's good news, though, making every PCB suit a unique specification is not a must. Why shouldn't you do this? Well, because it will prove very costly.

But as far as personalization goes, there's also what we call quasi-personalization. This means that some of these companies have standard services available to order a 'personalized' PCB. In doing this, it is not as expensive as you would have thought it would be.


10、pcb prototypes--The PCB Technology is Constantly Evolving


It is a fun fact you already know. Wrong! Evolution is unprecedented. Do you remember the story of Paul Eisler? When comparing the PCBs we had in his time and those we have now, you will appreciate how far we have reached technological advancement.

Do you want a peek into future evolutions? You've heard about flex PCBs with IoT capabilities, but what you might not know is that research is ongoing to develop the next generation of biodegradable PCB. It will contribute to our goal of a sustainable future.

Another important innovation is the development of graphene. Once this technology becomes commercially mature, the operation of solid-state electronics will change forever.


11、pcb prototypes--PCBs and Size

The future is small and compact; why shouldn't our PCBs be? Well, it's just a matter of time before we have tiny PCBs. Since its inception, you can observe that the PCB has also been shrinking in Size. This trend is set to continue, and now, the pressure is even heightened. Developers see the need to make smaller and smaller PCBs for a vast number of applications.

Here's an example of the technology driving the reduced Size; using the surface mount technology that we discussed earlier, we can design PCBs up to a tenth of the Size of the ones we create using through-hole technology. You can confidently predict that the PCB would be as small as you can imagine in a few years.


12、pcb prototypes--The Law Governing PCBs


Do you think these little devices are autonomous? What governs their actions? How do we even know how to utilize them properly? There are so many questions that pop up regarding this topic, but there's just one answer. Ohm's Law. It is the most famous law among electrical engineers and PCB prototype designers, and we shall explore it shortly.

Ohm's law is responsible for establishing the relationship between current, resistance, and voltage. Putting it in words, we can say that Ohm's law states that electrical current is directly proportional to voltage, and it is inversely proportional to resistance. This simple law tells designers and engineers how to develop PCBs and PCB prototypes, telling them the design implications of their choices.
