They offer high reliability as manufacturers want to stay longer in the consumer electronic business. PCBs are applicable in communication devices (such as smartphones, smartwatches, tablets, and radios), Computers, Entertainment systems (Televisions, Video game consoles, and stereos), and home appliances (including refrigerators, microwaves, washing machines, and beverage makers).

Industrial Equipment

Printed Circuit Boards have varied use in the industrial sector. The kinds of PCBs used in industrial machines are often high-powered and can withstand harsh conditions in industrial layouts.

PCBs in industrial sectors must resist handling, vibrations, extreme temperatures, and harsh chemicals. As a result, Manufacturers that produce industrial PCBs use durable or thermal-resistant metals that are thicker than other kinds of PCBs in other sectors.

Some of the industrial applications of PCBs include Manufacturing equipment (power drills and presses), power equipment (Generators, power inverters, solar power generators), Measuring equipment (used in the control of pressure, temperature, humidity, and other factors), and Robotics.

Automotive and Aerospace components

A growing number of electronic components are used in the Automotive and Aerospace sectors. In the Automotive industry, PCBs have advanced from simple wipers and headlight switches to making cars smarter, safer, and easier to drive. In the Aerospace world, PCBs are used mainly in space shuttles, satellites, and radio communications systems.

PCBs in the Automotive and Aerospace requires using materials that can withstand vibration, extreme temperatures, and severe conditions. Some PCB-enabled devices are used in outer space. As such, they must be highly durable and reliable.

Applications of PCBs in Automotive components include Entertainment and Navigation System (stereo, headlights, and brake lights), Control system (engine management systems and fuel regulators), and Sensors (which monitors blind spots and assists in automatic parallel parking)

PCB Industry Trends in 2022

High-Density Interconnects (HDI) PCBs

High-Density Interconnects (HDI) PCBs

These PCBs are high-performance yet small in size. Unlike traditional PCBs, they are made with fragile materials which allow compact wiring, tiny laser vias, and pads. Since High-Density interconnects PCBs require powerful yet fewer materials, the manufacturing process is cheaper and requires a unique technique to produce them.

HDI Printed Circuit Boards are preferred in small electronic products that are powerful smart, and efficiently such as wearable devices and rocket ships. The drive to make PCBs smaller and more powerful is one of the most influential industrial trends in the PCB industry.

3D Printed Electronics

3D Printed Electronic is an additive manufacturing process that can build 3D circuits by printing a substrate layer by layer. It enables faster prototyping with a short turnaround time. 3D printing eliminates the need for an assembly process as many machine parts can be built with 3D printing.

With the use of PCBs, 3D printers are transforming electrical systems design making them automated and improving efficiency.

Biodegradable PCBs

The PCB industry faces environmental regulations like every other global business to achieve sustainable business practices. The problem in the industry is that many circuit boards can last a decade and end up in a landfill, causing harm to the environment.

There is a debate regarding PCB finishes, which many believe contain lead in many PCBs and could potentially harm the environment with information seeping into the water.

Based on RoHS standards, PCBs no longer use Lead Hot Air Solder Leveling (HASL), and dozens of PCB finishes are cheaper and safer for the environment.

Flexible PCBs

Flexible PCBs

The flexible Printed Circuit Boards were an efficient yet innovative means to create advanced circuit boards that could bend to fit smaller spaces that a rigid PCB cannot. Flexible PCBs are arrangements of circuitry on flexible film layers. It could be single-sided, double-sided, multilayer, or hybrid.

Flexible PCBs have various applications, from electronic devices, automotive components, medical devices, and satellites equipped to withstand vibrations and high temperatures. However, they are challenging to repair and are costlier to produce than traditional PCBs.
