PCB Fabrication Innovations: What to Expect in 2024

In the dynamic world of pcb board fabrication, 2024 promises to be a year filled with groundbreaking innovations and advancements. Technological progress has been relentless, driving the industry towards new horizons. Let's delve into what we can expect on the PCB fabrication front in the upcoming year.

[reasonsforhope]

"As the world grows “smarter” through the adoption of smartphones, smart fridges, and entire smart houses, the carbon cost of that technology grows, too. 

In the last decade, electronic waste has become one of the fastest-growing waste streams in the world. 

According to The World Counts, the globe generates about 50 million tons of e-waste every year. That’s the equivalent of 1,000 laptops being trashed every second. 

After they’re shipped off to landfills and incinerated, the trash releases toxic chemicals including lead, cadmium, arsenic, mercury, and so much more, which can cause disastrous health effects on the populations that live near those trash sites. 

Fortunately, Franziska Kerber — a university student at ​​FH Joanneum in Graz, Austria — has dreamed up a solution that helps carve away at that behemoth problem: electronics made out of recyclable, dissolvable paper. 

On September 11, Kerber’s invention “Pape” — or Paper Electronics — earned global recognition when it was named a national winner of the 2024 James Dyson Awards. 

When she entered the scientific competition, Kerber demonstrated her invention with the creation of several small electronics made out of paper materials, including a fully-functional WiFi router and smoke detector. 

“Small electronic devices are especially prone to ending up in household waste due to unclear disposal systems and their small size, so there is significant potential to develop a more user-friendly end-of-life system,” Kerber wrote on the James Dyson Award website. 

“With this in mind, I aimed to move beyond a simple recycling solution to a circular one, ensuring long-term sustainability.” 

Kerber’s invention hinges on crafting a dissolvable and recyclable PCB board out of compressed “paper pulp.” 

A printed circuit board (PCB) is a board that can be found in nearly all modern electronic devices, like phones, tablets, and smartwatches.

But even companies that have started incorporating a “dissolution” step into the end life of their products require deconstruction to break down and recover the PCB board before it can be recycled. 

With Kerber’s PAPE products, users don’t need to take the device apart to recycle it.

“By implementing a user-friendly return option, manufacturers can efficiently dissolve all returned items, potentially reusing electronic components,” Kerber explained. 

“Rapidly advancing technology, which forms the core of many devices, becomes obsolete much faster than the structural elements, which are often made from plastics that can last thousands of years,” Kerber poses. 

PAPE, Kerber says, has a “designed end-of-life system” which anticipates obsolescence. 

“Does anyone want to use a thousand-year-old computer?” Kerber asks. “Of course not. … This ensures a sustainable and reliable system without hindering technological advancement.”"

Printed Circuit Board Basics

Most of us are using Printed Circuit Board in our daily life. Printed Circuit Boards are used in almost all the Electronic products, from consumer gadgets such as PCs, tablets, smartphones, and gaming consoles to industrial and even high tech products in strategic and medical electronics domains.

Here, we have some statistics for you that shows how many electronic devices connect worldwide from 2015 to 2025. This statistic shows an increase in the use of a number of PCB in people daily life. Hence, CircuitWala took this opportunity to provide a basic knowledge about PCB via this article.

There are so many books available online which teach about Printed Circuit Board design and hardware part. There are few links available online which shows only a few basic fundamentals of PCB and few are there for Basics of Printed Circuit Board (PCB) Design. Few which gives good know knowledge on Printed Circuit Board terminology. But in the end for the hobbyist, there is no such material available which make their work easy.

Now days there few online designing websites available which allow hobbyist and students to create their design and Printed Circuit Board fabrication part. These websites provide limited features and charge high for the full edition. We, @CircuitWala are in try to provide one platform which provides plenty of Printed Circuit Board knowledge digitally to make your work simple and easy.

Alternatives of PCB include wire wrap and point-to-point construction. Creating a layout of PCB is a little bit time-consuming method as compared to its alternative solution but manufacturing of PCB is cheaper and faster then other wiring methods as electronic components are mounted and wired with one single part.

Let’s start with some basics of Printed Circuit Board with this article. Here in this article we will discuss about history of PCB to understand the emerge of PCB, Types of PCB to make your complex PCB a very simple using different types, Usage of PCB to provide you an idea to create more Printed Circuit Board projects, Advantages and Disadvantages, Possible Future to know about new technological change in Printed Circuit Board manufacturing and also about how to destroy and manage your PCB’s e-waste? We know you are eager to know all the stuff in details but before that let’s make a simple definition of Printed Circuit Board.

What is Printed Circuit Board?Printed Circuit Board is an electronic device made of conductive material(FR-4) like copper which connects components mounted on it to to get desired output by providing an input on another end.

When the board has not mounted with any of the components is called as Printed Circuit Board or Printed Wired Board. Mounting of an electronic component on Printed Circuit Board is called as PCB assembly.

History of Printed Circuit BoardThe invention of Printed Circuit Board was by Austrian engineer Paul Eisler as part of a radio set while working in England around 1936.

In early days before Printed Circuit Board became common in use, Point-to-Point construction was used. This meant some bulky and unreliable design that required plenty of sockets and regular replacement of it. Most of this issue directly address when PCB went into regular production.

Originally, every electronic component had wire leads, and the PCB had holes drilled for each wire of each component. The components’ leads were then passed through the holes and soldered to the PCB trace. This method of assembly is called Through-Hole construction. There is one other method to mount component is called as Surface Mount.

Type of Printed Circuit BoardPCBs are produced from the different types of material and on the basis of that material PCBs are divided mainly into two parts: Rigid PCB and Flexible PCB. Nowadays, a combination of Rigid and flexible PCB is also possible and that is called as Flexi-Rigid PCBs.

Most of the PCBs are built in layers. The inner layer is the base material called as a substrate. Rigid PCBs are mainly made of material like epoxy materials and Flexible PCBs are made of plastic material that can withstand high temperatures.

Rigid PCBs are generally, hard materials that hold the component in a better way. The motherboard in the tower of a computer is the best example of Rigid PCBs. Flexible PCBs fundamental material allows PCB to fit into forms that Rigid PCBs can not. Flexible PCBs can turn round without harmful the circuit on PCB.

All Rigid and Flexible PCBs can come in three formats by layers: Single Layer, Double Layer, and Multi-Layer.

1. Single Layer PCBSingle Layer PCBs have been around since the late 1950s and still dominate the world market in sheer piece volume. Single Sided PCBs contain only one layer of conductive material and are best suited for low-density designs. Single-sided PCBs are easy to design and quick to manufacture. They serve as the most lucrative platform in the industry.

2. Double Layer PCBDouble Layered printed circuit board technology is conceivably the most popular type of PCB in the industry. Double Sided PCB (also known as Double-Sided Plated Thru or DSPT) circuits are the gateway to advanced technology applications. They allow for a closer (and perhaps more) routing traces by alternating between top and bottom layers using vias.

3. Multi Layer PCB

Multilayer PCB is a circuit board that has more than two layers. Unlike a Double-Sided PCB which only has two conductive layers of material, all multilayer PCBs must have at least three layers of conductive material which are buried in the center of the material.

Usage of Printed Circuit BoardBy reading this article till this point, we hope that you are now able to get about printed circuit boards. Now, we will make you understand about different applications of printed Circuit Board.

In this digital world, Printed Circuit Board is in almost all our daily life electronic devices and in our industrial electronics as well. Below are the industries where PCBs are used:

Possible FutureNowadays, most of the circuits are replaced to produce Printed Circuit Board from the old methods. Revolution in technology made many of the processes automated and hence it is easy to manufacture PCB. But still, these processes are a bit expensive to hire, involve toxic waste and use high temperatures and acids. With technological advances we have seen in the past years, it is not hard to imagine PCB will soon be revolutionized. Not only that but research institutes predict a more ‘green’ future for PCBs; PCBs being made of paper.

Electronic Waste (e-waste)Electronic Waste or e-waste is described as discarded electrical or electronic devices. Informal processing of e-waste in developing countries can lead to adverse human health effects and environmental pollution.

Electronic scrap components contain a hazardous substance such as lead, cadmium, beryllium, or brominated flame retardants. Recycling and disposal of e-waste may involve significant risk to health of workers and communities in developed countries and great care must be taken to avoid unsafe exposure in recycling operations

Nowadays, developing countries are encouraging electronic users to take care while recycling the e-waste or submit them to the organization who are involved in such activities.

SummaryIn this blog, we have learned the basics of Printed Circuit Board. CircuitWala is planning to write as many blogs to provide more and more knowledge of Printed Circuit Board. Either it is basics or manufacturing or usages or advantages and disadvantages of PCBs. We will also try to make our users/customers up to date for the new technology innovations, including past histories and revolution of the PCB industries.

In the next blog, we will look at more briefly about the different types of Printed Circuit Board. We also understand the process to make it and different usage and application for the same.

The Evolution and Advantages of HDI PCB Fabrication in Modern Electronics

High-Density Interconnect (HDI) Printed Circuit Boards (PCBs) represent a significant advancement in PCB technology, offering enhanced performance and miniaturization for modern electronic devices. As consumer demand for smaller, faster, and more powerful electronics continues to grow, HDI PCBs have become a critical component in meeting these requirements. This article explores the evolution, fabrication process, and advantages of HDI PCB fabrication, highlighting its impact on the electronics industry.Get more news about Hdi PCB fabrication,you can vist our website!

The Evolution of HDI PCBs The development of HDI PCBs has been driven by the need for increased functionality and reduced size in electronic devices. Traditional PCBs, while effective, have limitations in terms of layer count, component density, and signal integrity. HDI technology addresses these limitations by incorporating advanced design and manufacturing techniques that enable higher component density and improved electrical performance.

The evolution of HDI PCBs can be traced back to the 1980s when the first multi-layer PCBs were introduced. Since then, advancements in materials, fabrication methods, and design software have led to the creation of HDI PCBs with multiple layers, finer lines and spaces, and smaller via structures. Today, HDI technology is widely used in various industries, including consumer electronics, telecommunications, automotive, and aerospace.

The HDI PCB Fabrication Process The fabrication of HDI PCBs involves several key steps, each contributing to the overall performance and reliability of the final product:

Design and Layout

The fabrication process begins with the design and layout of the HDI PCB. Advanced design software is used to create detailed schematics and layouts that optimize the placement of components, vias, and traces. Designers must consider factors such as signal integrity, thermal management, and manufacturability during this phase.

Material Selection

The choice of materials is critical for the performance of HDI PCBs. High-quality laminates, copper foils, and prepregs are selected to ensure the board's durability, electrical performance, and thermal stability. The materials must also be compatible with the specific fabrication processes used for HDI PCBs.

Laser Drilling and Via Formation

One of the defining features of HDI PCBs is the use of microvias—small, high-density vias that connect different layers of the PCB. Laser drilling technology is employed to create these microvias with precision and accuracy. Blind, buried, and stacked vias are commonly used in HDI PCBs to achieve higher interconnect density and improved signal performance.

Layer Lamination

The individual layers of the HDI PCB are laminated together using heat and pressure. This process ensures a strong bond between the layers and helps achieve the desired mechanical and electrical properties. The lamination process must be carefully controlled to prevent defects such as delamination or misalignment.

Patterning and Etching

After lamination, the copper layers are patterned and etched to create the desired circuit traces. Advanced photolithography and chemical etching techniques are used to achieve fine line widths and precise trace patterns. The accuracy of this step is crucial for the overall performance of the HDI PCB.

Surface Finishing and Solder Mask Application

The exposed copper traces are coated with a protective surface finish to prevent oxidation and improve solderability. Common surface finishes include ENIG (Electroless Nickel Immersion Gold), HASL (Hot Air Solder Leveling), and OSP (Organic Solderability Preservative). A solder mask is then applied to the board to protect the traces and prevent solder bridging during component assembly.

Inspection and Testing

The final HDI PCB undergoes rigorous inspection and testing to ensure its quality and reliability. Automated optical inspection (AOI), X-ray inspection, and electrical testing are performed to detect any defects or issues. This step ensures that the HDI PCB meets the required specifications and performs as intended.

Advantages of HDI PCBs Increased Component Density

HDI technology allows for higher component density by utilizing microvias, fine lines, and multiple layers. This increased density enables the integration of more components and functionalities into a smaller footprint, making HDI PCBs ideal for compact electronic devices.

Improved Signal Integrity

The shorter signal paths and reduced parasitic effects in HDI PCBs result in improved signal integrity and reduced signal loss. This advantage is particularly important for high-speed and high-frequency applications where signal performance is critical.

Advancing Technology with Multilayer PCB Manufacturing

Advancing Technology with Multilayer PCB Manufacturing

Printed Circuit Boards (PCBs) are the backbone of virtually all electronic devices, enabling the complex circuitry required for modern technology. Among the various types of PCBs, multilayer PCBs have become essential due to their ability to support advanced electronic designs and high-performance applications. This article explores the process, benefits, and applications of multilayer PCB manufacturing, showcasing their critical role in advancing technology.Get more news about Multilayer PCB manufacturing,you can vist our website!

Understanding Multilayer PCBs A multilayer PCB consists of multiple layers of conductive material separated by insulating layers (also known as dielectric layers). These layers are stacked and bonded together to create a compact, complex structure that allows for the routing of intricate electronic circuits. Multilayer PCBs can have anywhere from three to over 50 layers, depending on the complexity and requirements of the application.

The Manufacturing Process of Multilayer PCBs Design and Layout

The manufacturing process begins with the design and layout of the PCB. Engineers use specialized software to create a detailed blueprint of the circuit, including the placement of components, traces, and vias. This design is then used to create photomasks for each layer of the PCB.

Layer Stacking and Bonding

The individual layers of the PCB are fabricated separately, with each layer consisting of a thin sheet of conductive material (usually copper) laminated onto an insulating substrate. These layers are then stacked in the correct order and bonded together using heat and pressure. This process, known as lamination, ensures that the layers are securely attached and aligned.

Drilling and Plating

Once the layers are bonded, holes are drilled through the stack to create vias, which are used to connect the different layers of the PCB. The drilled holes are then plated with a conductive material, such as copper, to establish electrical connections between the layers.

Etching

The next step is etching, where the unwanted copper is removed from each layer to create the desired circuit patterns. A chemical solution is used to dissolve the excess copper, leaving behind the intricate traces and pads that form the PCB's circuitry.

Solder Mask and Silkscreen

After etching, a solder mask is applied to the PCB to protect the copper traces from oxidation and prevent solder bridges during component assembly. The solder mask also gives the PCB its characteristic green color. Finally, a silkscreen layer is added to print component labels, logos, and other markings on the PCB.

Testing and Quality Control

Before the PCB is ready for use, it undergoes rigorous testing to ensure its functionality and reliability. Automated testing equipment checks for continuity, shorts, and other defects. Any issues detected are addressed, and the PCB is re-tested until it meets the required standards.

Benefits of Multilayer PCBs Compact Size and Space Efficiency

Multilayer PCBs allow for more complex circuitry to be accommodated in a smaller footprint. By stacking multiple layers, designers can create compact and space-efficient electronic devices, which is particularly important in applications where size and weight are critical factors.

Enhanced Performance and Reliability

The use of multiple layers enables the separation of different signal types, reducing electromagnetic interference (EMI) and improving signal integrity. This results in enhanced performance and reliability, making multilayer PCBs ideal for high-speed and high-frequency applications.

Increased Design Flexibility

Multilayer PCBs offer greater design flexibility, allowing engineers to implement more complex and sophisticated circuits. The additional layers provide more routing options, enabling the creation of advanced electronic designs that would be challenging to achieve with single-layer or double-layer PCBs.

Improved Thermal Management

The increased number of layers in multilayer PCBs allows for better distribution of heat generated by electronic components. This improved thermal management helps prevent overheating and extends the lifespan of the device.

Applications of Multilayer PCBs Consumer Electronics

Multilayer PCBs are widely used in consumer electronics, including smartphones, tablets, laptops, and wearable devices. The compact size and high performance of these PCBs make them ideal for modern gadgets that require sophisticated functionality in a small form factor.

Automotive Industry

The automotive industry relies on multilayer PCBs for various applications, including engine control units, navigation systems, and advanced driver-assistance systems (ADAS). The reliability and durability of multilayer PCBs ensure the safe and efficient operation of electronic systems in vehicles.

Telecommunications

In telecommunications, multilayer PCBs are used in networking equipment, data servers, and communication devices. The ability to handle high-speed data transmission and reduce EMI makes these PCBs essential for maintaining the performance and reliability of communication networks.

Medical Devices

Multilayer PCBs play a crucial role in medical devices, such as diagnostic equipment, patient monitoring systems, and implantable devices. The precision and reliability of these PCBs are critical for ensuring the accuracy and safety of medical applications.
