Several key factors are driving the growth of the PCB encapsulation market. As electronic devices become more complex and miniaturized, there’s a growing need for advanced protection solutions to ensure their durability and performance. The surge in consumer electronics, including smartphones, tablets, and wearables, has increased demand for these adhesives, as these devices need robust protection against moisture, dust, and thermal stress. Additionally, the automotive industry’s expansion, especially with the rise of electric vehicles and autonomous driving technologies, heightens the need for reliable PCB protection to improve safety and functionality. Advances in adhesive technologies that offer better thermal conductivity, flexibility, and environmental resistance are also contributing to market growth. Furthermore, strict regulations and standards for electronic device performance and safety are driving the adoption of high-quality PCB encapsulation across industries such as aerospace, defense, healthcare, and industrial automation. The growing prevalence of Internet of Things (IoT) and Industry 4.0 technologies, which connect more devices, also supports market expansion by increasing the demand for durable and reliable PCB protection solutions.
Major players in this market compete through product innovation, strategic partnerships, acquisitions and geographic expansion to cater to the diverse needs of various end-use industries globally.
Based on type, the PCB encapsulation market has been segmented into Epoxy, silicone, acrylic, polyurethanes and others. Epoxy will be the fastest growing resin type, in terms of value, of the global market in 2024.
The resin type segment is gaining tremendous momentum in the PCB protection market, with the epoxy resins category being the fastest-growing. This can be attributed to various reasons, the important ones being the superior properties that epoxy resins exhibit, like excellent mechanical strength, good chemical resistance, and high thermal stability. Because of these valuable qualities, epoxy resins have become most useful and in great demand in electronic applications where reliability and long life are considered of prime importance. Furthermore, the increasing complexity of electronic devices and the demand for high-performance protection of PCBs have displaced the demand for epoxy resins, thereby offering advanced protection and extending operational life. With the constant changes in technology and electronic devices becoming ever more complex, the preference for epoxy resins in protecting printed circuit boards will only rise and cement its position as the leading segment under the category of resin type.
Based on product type, the PCB encapsulation market has been segmented into Glob Top, Dam & Fill, Conformal Coating, Underfill, Connect Bonding and Others. Conformal coatings accounted for the largest share, in terms of value, of the global market in 2024.
The product type segment of the PCB protection market is being fueled by the fastest growth in conformal coatings. Now, one of the major drivers behind it is that these coats offer excellent insulation, resistance to moisture, and protection from environmental contaminants—very critical parameters for the reliability and durability of an electronic circuit. The demand for the conformal coating process is growing due to increasing electronic circuit complexity and reflow conditions. Advancing technologies in coating, such as developing more effective and application-friendly formulations, further accelerate the adoption of conformal coatings. These attributes combined drive the growth of conformal coatings in the protection of PCBs, hence forming an extremely important part in protecting electronic assemblies.
Based on end-use industry, the PCB encapsulation market has been segmented into consumer electronics, automotive electronics, aerospace & defense, medical devices and others. Consumer electronics accounted for the largest share, in terms of value, of the global market in 2024.
The application segment of the PCB protection market is growing pervasively, and within that, consumer electronics are the fastest-growing sector. The various factors that may drive this trend are basically the fast growth and increasing trend in consumer electronic devices, including smartphones, tablets, and other wearables. These devices face a wide exposure to different kinds of environmental stresses, such as moisture, dust, and mechanical impacts, hence requiring strong PCB protection. There is a growing demand for high-performance, durable consumer electronics, which further fuels the need for effective protection solutions for PCBs. In addition, innovation in consumer electronics never stops; and the drive to extend the life and reliability of devices is gaining momentum—so there is an increasingly important role that advanced PCB protection technologies can play. The growth in this segment of the PCB protection market continues to remain driven by an increasing proliferation and evolving nature of consumer electronics that calls for specialized protection to guarantee functionality and durability.
