Kai Ji Circuit Board has introduced Christie LDI, ushering in a new era of high precision in PCB manufacturing

Million-level new infrastructure is now in place! Kai Ji Circuit Board has introduced Christie LDI, ushering in a new era of high precision in PCB manufacturing

In the trend of miniaturization and high-performance development of electronic components, the precision and yield of printed circuit boards (PCB), as the "nerve center" of electronic products, directly determine the quality of end products. Recently, Zhongshan Kaiji Circuit Board Co., Ltd. (hereinafter referred to as "Kaiji Circuit Board") officially completed a million-level equipment upgrade, introducing a Christie optical solder mask double-sided simultaneous exposure LDI equipment. With the industry's top direct imaging technology, it injects new momentum into high-end PCB manufacturing, marking the company's new peak in the field of high-precision circuit board production.
With over three decades of deep industry experience, Kai Ji Circuit Board has firmly established its foundation in quality
As a benchmark enterprise in the PCB manufacturing sector in Zhongshan City, Kai Ji Circuit Board has been adhering to the core philosophy of "customer orientation and quality first" since its establishment in 1989. After more than three decades of development, the company has grown into a high-tech enterprise integrating research and development, production, and sales. It boasts modern dust-free workshops and a well-established production process, employs over 400 people, and achieves a monthly production capacity of 90,000 square meters. Its products cover single-sided, double-sided, multilayer circuit boards, aluminum substrates, etc., and are widely used in LED lighting, household appliances, industrial control, and other fields.
The company has successively obtained ISO9001 quality management system certification, ISO14001 environmental management system certification, and UL certification from the United States. With its green and environmentally friendly lead-free raw materials and refined production processes, it has won widespread recognition from customers both domestically and internationally. The introduction of this million-level equipment marks a crucial step in Kai Ji Circuit Board's implementation of its "continuous breakthrough" development strategy. It aims to further overcome precision bottlenecks and meet the stringent demands for high-end PCBs in fields such as 5G communication, new energy vehicles, and high-end displays.
Christie LDI breaks the mold and innovates, redefining PCB exposure technology
The Christie solder mask connection double-sided simultaneous exposure LDI equipment introduced by Kai Ji Circuit Board is developed by Christie Optics, a national-level "Little Giant" enterprise specializing in precision, fine, unique, and innovative technologies. It integrates multiple breakthrough technologies and precisely addresses the pain points of traditional industry processes.
Vertical dual-side simultaneous exposure overcomes traditional process challenges. Traditional LDI equipment often adopts a horizontal exposure design, relying on blower negative pressure to adsorb PCBs, which can easily lead to issues such as solder mask bleeding, oil loss, and copper leakage. At the same time, it cannot achieve dual-side simultaneous operation, limiting efficiency and yield. Christie LDI innovatively adopts a vertical upright exposure design, where the PCB has no contact with the platform during exposure, completely eliminating the dependence on blowers. This fundamentally solves persistent problems such as ink leakage and copper leakage, while achieving simultaneous dual-side exposure. Imaging consistency and process stability are greatly improved, and yield is significantly optimized.
The equipment achieves both cost reduction and efficiency enhancement, optimizing both aspects. When adapting to large-scale production equipment, it not only improves quality but also reduces costs throughout the entire process. With a connection length of only 2.85 meters, it saves over 50% of clean room space compared to traditional single-sided exposure LDI (6.0-7.0 meters), significantly reducing site costs. In terms of energy consumption, it eliminates the need for blower assistance, achieving a comprehensive power saving of 8-15KW per hour. Additionally, it reduces the consumption of air conditioning cooling in the clean room, saving another 5-20KW per hour in energy consumption, highlighting its green and low-carbon attributes. Furthermore, the equipment eliminates the need for high-cost anti-adhesion cover plates (requiring replacement every 3-6 months), effectively reducing consumable expenses over the long term and creating considerable economic benefits for enterprises.
Adapted to high-end scenarios and expanding product boundaries, Christie LDI relies on a 405nm precise light source and a high-precision optical system. It is compatible with various photosensitive materials such as traditional dry film, wet film, and LDI-specific film, supports Gerber274X format file input, and can be widely applied in high-end PCB fields such as IC carrier boards, flexible boards, HDI boards, and ceramic substrates. The implementation of this equipment will help Kai Ji Circuit Board break through the limitations of traditional products and extend into the PCB field with higher precision and higher added value, meeting the customized needs of emerging industries such as new energy vehicles, Mini/Micro LED displays, and advanced packaging.
Empowered by technology, Kai Ji circuit board aims to become a new benchmark in the industry
The implementation of million-level equipment marks a significant milestone in the technological upgrade of Kai Ji Circuit Board. It also serves as the core foundation for the company to delve deeper into the PCB manufacturing field and expand into the high-end market. Looking ahead, leveraging the technological advantages of Christie LDI equipment, the company will further optimize its production processes, enhance its high-end PCB production capacity and quality, and prioritize the research, development, and production of core products such as 5G communication base station boards, new energy vehicle control boards, and high-end display driver boards.
Meanwhile, Kaiji Circuit Board will continue to strengthen technological innovation and supply chain integration, leverage the local advantages of Zhongshan's electronic manufacturing industry, expand high-quality customer resources both domestically and internationally, promote the export of products to multiple countries around the world, including the United States, the United Kingdom, South Korea, and Vietnam, and continuously empower the upgrading of the global electronic manufacturing industry chain.
From traditional craftsmanship to high-precision and advanced equipment, Kai Ji Circuit Board, with technology as its wings and quality as its foundation, is accelerating towards becoming an industry benchmark enterprise. The implementation of Christie LDI equipment not only injects new vitality into the company's own development, but also promotes the transformation of the regional PCB manufacturing industry towards high-end and intelligent development, contributing solid strength to the high-quality development of China's electronic manufacturing industry.
With millions of new equipment in place, Kaiji Circuit Board will continue to produce high-quality PCB products with stricter standards and more advanced technology. We will work together with industry partners to embrace a new era of electronic manufacturing!
