A printed circuit board (PCB) is a flat board made of insulating material, often fiberglass, that supports and connects electronic components using conductive pathways etched from copper sheets. From smartphones and computers to industrial machinery and medical equipment, PCBs are now the essential components in the modern electronics industry. Accordingly, our research predicts that the Global Printed Circuit Board Market is likely to grow with a CAGR of 5.04% in the forecast period 2024-2032. As the need for advanced technologies surges, so does the demand for printed circuit boards that are efficient, reliable, and innovative.

Traditional PCB manufacturing processes can be resource-intensive and generate significant waste, particularly in terms of hazardous chemicals like lead and volatile organic compounds (VOCs). In response, printed circuit board manufacturers are now exploring biodegradable materials, eco-friendly inks, and energy-efficient production methods.
Let us take a look at some interesting examples of key market players in this industry.
Companies, such as Jiva Materials in the UK, are pioneering the use of biodegradable materials in PCB production. They have developed a product called Soluboard, which replaces the traditional fiberglass substrate with natural fibers that break down in water. Soluboard is not only biodegradable but also lowers carbon emissions during production.
As per its press release, Infineon incorporates recyclable PCBs from Jiva Materials in its demo and evaluation boards to reduce electronic waste and lower its carbon footprint. Furthermore, switching from FR-4 PCB materials to Soluboard could cut carbon emissions by 60%. This change would save approximately 10.5 kg of carbon and 620 g of plastic per square meter of PCB.
Thus, by switching to biodegradable substrates, manufacturers can significantly reduce the environmental footprint of PCBs, making electronics more sustainable from the outset.
Linx Technologies, a developer of wireless IoT products, has created smart PCBs optimized for smart home applications. These PCBs feature integrated wireless modules (such as Wi-Fi, Bluetooth, and Zigbee) that allow devices like smart thermostats, lighting systems, and security cameras to communicate within a home ecosystem.
The company also partnered with a leading smart thermostat manufacturer to design a PCB that integrates multiple communication protocols, enabling the thermostat to adapt and respond to changing environmental conditions and user preferences.
As agriculture becomes more data-driven, John Deere has introduced smart PCB solutions within its precision farming equipment. These PCBs incorporate sensors and GPS modules that collect and transmit data on soil moisture, nutrient levels, and crop health. The collected data helps optimize farming practices by providing actionable insights to farmers. In one case study, John Deere implemented smart PCBs in its autonomous tractors and harvesting equipment.

The Asia-Pacific region is set to witness remarkable growth in PCB manufacturing due to its expanding consumer electronics and automotive industries, growing semiconductor market, and favorable government policies supporting tech infrastructure. The Asia-Pacific Printed Circuit Board Market is expected to witness the fastest growth at a CAGR of 5.64% during the forecast period.
Here’s how countries are influencing this growth:
Taiwan remains at the forefront of advanced PCB manufacturing, particularly in the high-density interconnect (HDI) and substrate-like PCB (SLP) markets. Taiwanese printed circuit board companies like Unimicron and Nan Ya PCB dominate the market, holding a significant share of the global IC substrate sector. In fact, California-based Bloom Energy has signed an agreement with Unimicron to install up to 10 MW of fuel cells at its Taiwan plants, with the installations set to be completed by 2026. These investments position the country as a key supplier for global tech giants like Apple and NVIDIA, demonstrating its pivotal role in the market’s future growth.
In addition to this, BPL launched a new PCB production unit in Bengaluru, India (June 2024), backed by a ₹20 crore investment to support commercial production of double-sided and multi-layer PCBs. Amber Enterprises recently announced plans to invest ₹2,000 crore in establishing a printed circuit board (PCB) manufacturing facility in India to meet both domestic and export demands. These efforts reflect India’s growing commitment to expanding PCB manufacturing capacity and contributing to the region’s PCB market potential.
Similarly, the South Korean government unveiled a $19 billion support package aimed at bolstering the country’s tech sector, specifically focusing on enhancing semiconductor and PCB manufacturing capabilities. This package supports companies like Samsung Electronics and SK Hynix, encouraging investments in advanced manufacturing and R&D to maintain their edge in high-performance PCBs for the electronics and automotive sectors.
Together, these countries, along with other regions like Europe and North America, are strengthening their PCB manufacturing capabilities through strategic investments, international collaborations, and technology development, ensuring their positions in the PCB Industry. Thus, the ongoing innovations and developments in this market indicate a promising future where advanced technologies and sustainable practices merge to meet global demand.
