Users now have heightened expectations for PCBs, seeking faster speeds, smaller sizes, and quicker time-to-market. These demands present both challenges and opportunities for PCB design. For customers, the ideal scenario is to achieve a faster design delivery time while still meeting performance specifications.
1. A high-quality PCB must address signal integrity, power integrity, and electromagnetic compatibility in its design, which fundamentally impacts circuit performance. Visually, an excellent PCB should exhibit tight spacing, neatness, and symmetry, while also considering the aesthetics of the layout. Additionally, it should align with user habits, such as the thoughtful placement of panel sockets for easy plugging and unplugging, along with clear safety instructions.
2. According to industry standards, a good PCB must primarily meet user performance requirements while also ensuring reliability, ideally at a competitive cost. However, the emphasis on these three aspects may vary depending on the specific product.
3. Currently, due to an ongoing chip shortage and prolonged price increases, many domestic electronics companies are responding by localizing or substituting chips. This has led to a significant number of products requiring PCB redesigns. Some PCB manufacturers have promoted collaboration with various companies and universities through free prototyping, fostering enthusiasm among educators and students that has contributed to growth in the PCB manufacturing market.
4. While the demand for PCBs in new energy vehicles has surged, the integration of large-capacity batteries increases circuit current, making current-carrying and thermal designs critical. Reliability becomes paramount for PCBs, with heat being a major factor affecting performance. Therefore, managing heat dissipation from the IC package through the PCB to the final product in operational conditions is essential.
5. Moreover, new energy vehicles incorporate technologies such as autonomous driving, radar, and smart cockpits, complicating PCB design compared to traditional vehicles. To support these advanced functions, signal speed requirements on PCBs will be higher, potentially necessitating the use of HDI boards in smart cockpits. Additionally, these vehicles often include multiple camera modules, increasing the need for both rigid and flexible PCBs.
6. Beyond new energy vehicles, high-end PCB manufacturing in support of integrated circuit industries, such as semiconductor testing equipment, is expected to experience rapid growth in the future. Historically, this sector has been dominated by countries like the United States, Japan, and South Korea.
7. In the display technology realm, particularly with the next generation of active light-emitting LEDs, the backlight modules are often as large as the screens themselves, resulting in equally large PCBs. These display devices are typically utilized in applications such as large-screen monitoring and outdoor advertising, with current market demand on the rise.
