PCB manufacturing is an industry that has experienced a lot of growth. And with the introduction of technologies such as Artificial Intelligence, 5G, and the Internet of Technology, there are new trends in PCB manufacturing.
With many inventions, the PCB industry has changed for the better. Many new developments have made printed circuit boards more reliable and effective. Here are four recent PCB manufacturing trends shaping electronic devices’ future.
PCB Manufacturing Trends You Need To Know
1. Flex PCB
The introduction of flex PCBs has changed electronic gadgets’ shape, weight, design, and size. They can easily fit in spaces where rigid PCBs cannot fit. Flexible printed circuit boards are well designed to improve the flexibility of electronics.
With flex PCB, it is possible to move and bend the PCB without damaging it. Moreover, you can use single-sided flex PCB, double-sided flex PCB, multilayer flexible PCB, and rigid-flexible PCB.
Flexible PCBs are mainly used in various electronic gadgets like scanners, printers, smart devices, medical gadgets, and aerospace.
Advantages of flex PCBs
*Since they are flexible, flex PCBs are used in many products across the sectors.
*They are reliable because there is no risk of wire connection failure
*Flex PCBs can be used in harsh conditions
*Flexible PCBs are smaller compared to rigid and other PCBs.
Applications of Flexible PCBs
Flexible PCBs are used in various sectors that include:
*Automotive – flexible PCBs are common in the automotive sector. You will find them in climate control gadgets, GPS, and rearview cameras, among other devices.
*Commercial electronics – flexible circuit boards have become vital with commercial electronic gadgets. They have made the devices smaller, effective, and more advanced. You will find them in smart devices, printers, scanners, and many others.
2. Biodegradable PCB
Although electronic gadgets are made to improve life, they have become a threat to the environment. Since most of them have a small lifespan, they end up as waste after being thrown away.
Based on several studies, PCBs are some components that release many toxic substances into the environment. Happily, manufacturers have come up with a new trend in PCB manufacturing to protect the environment.
They have come up with printed circuit boards that are biodegradable. Biodegradable PCBs are environmentally friendly. They are made in a way that, when exposed to water, can break down within a very short time.
In addition, they are made from banana stems, wheat gluten, or chicken feathers. Moreover, the manufacturers are testing other methods to design and manufacture partially biodegradable PCBs and fully biodegradable PCBs.
3. 3D Printing PCB
3D printing, also known as additive manufacturing, has become very popular with PCB manufacturers. This is due to the benefits it has over most traditional manufacturing methods.
3D is the process of creating 3-dimensional objects from a computer file. It is an additive process used by building up layers of material to create a 3D object. It involves layering materials such as bio-materials, plastics, and composites.
Benefits of 3D printing PCB
Flexible PCB designs – 3D printing allows the designing and printing of PCB complex designs more than when using traditional manufacturing methods. Most old manufacturing methods have restrictions but do not apply to 3D printing.
Rapid Prototyping – 3D printing makes it possible to manufacture parts within hours. Hence, it is a manufacturing trend that speeds up the prototyping process. It allows each stage to finish faster.
Cost – 3D printing is among the most cost-effective manufacturing processes. Compared to the traditional methods, 3D needs fewer labor costs and does not need experienced machine operators.
Environmentally friendly – 3D is a technology that reduces waste materials. Hence, it is a great technology that minds the environment.
4. HDI PCB
The manufacturing of printed circuit boards has evolved from single-sided printed circuit boards to multilayer PCBs. And now, there is the introduction of High-Density Interconnect PCBs or HDI. It is a circuit board with a higher wiring density.
HDI PCBs are some of the fastest-growing technologies in the printed circuit sector. This is because they come with numerous benefits. For example, PCBs improve signal transmission speed and the placement of a few layers on the board.
Since HDI PCB can be populated on each side of the board, many elements can be attached to a small board. Thus, it is possible to find a small and lightweight PCB that is powerful and reliable.
Benefits of High-density interconnect PCBs.
*HDI printed circuit boards are excellent when your primary concerns are space, reliability, weight, and performance. The boards are the best compared to other printed boards.
*Another benefit of HDI PCBs is that they are reliable against extreme environmental conditions.
*Compared to other PCBs, HDI PCBs are cost-effective. This is because it can reduce an HDI board without compromising the quality.
*HDI PCBs offer better signal integrity than standard printed circuit boards.
*The board has space requirements dueThe board has space requirements due to a mixture of buried vias, blind vias, and micro-vias.
Application of HDI PCBs
Automotive – car manufacturers are looking for small and effective printed circuit boards to save vehicle space. Hence, the best option is HDI PCBs. Hence, these circuit boards play an essential role in the automotive industry.
Healthcare – HDI PCBs are vital components in the health sector. Apart from being reliable and effective, they fit well in small devices such as diagnosing equipment, monitoring devices, and many other items.
Wearable technology – HDI PCBs have become an essential element in wearable technology. For instance, Apple watches and many wearable gadgets use HDI PCBs.
Tablets and smartphones – most modern tablets and smartphones use HDI PCBs. This is because PCBs are excellent for creating smaller, more portable electronic gadgets.
Final Word
These are among the new trends in PCB manufacturing. The trends have managed to make the PCB industry grow, produce the best products, and make life simpler. This means the future of the PCB industry is bright and expected to grow even more.
Moreover, more trends are expected to come up in the future. Thus, you should expect reliable, smaller, lighter, and eco-friendly printed circuit boards to be produced in the future.
