Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of laser imaging, specifically a laser direct imaging exposure device. BACKGROUND

[0002] Direct Laser Imaging (DLI) is one of the advanced manufacturing technologies that has been rapidly developing in recent years, and is widely used in printed circuit board (PCB), semiconductor and other high-precision patterning manufacturing fields. With the diversification and integration of electronic products, the demand for high-precision and high-efficiency production equipment is increasing, and laser imaging technology has emerged as the times require. Traditional photolithography process relies on film and light source, and realizes patterned manufacturing through exposure and development steps. This process is not only cumbersome, but also prone to pattern precision and consistency problems due to the need for film and multiple processes. In addition, the long plate-making time, high cost and difficulty in modifying bugs of traditional process make it gradually face the challenges of the automation and digital era.

[0003] Laser direct imaging technology uses a laser to directly engrave the design pattern on photosensitive material, eliminating the need for traditional equipment such as film and exposure machine, significantly improving production efficiency and imaging precision. The key to laser exposure is its controllability and high resolution, which can realize micron-level pattern transfer and is suitable for the manufacturing of high-density interconnection (HDI) and complex circuits. Because the laser beam has high directionality and adjustability, it can be accurately focused on the surface of the photosensitive layer to form high-quality patterns. With the continuous progress of laser technology, DLI equipment has been significantly improved in imaging speed, resolution and stability. Many well-known circuit board manufacturers have begun to adopt this technology, further promoting the innovation and development of the industry. At the same time, laser direct imaging technology shows good prospects in ecological environmental protection, reducing the use of chemicals and waste in traditional photolithography process, meeting modern environmental protection requirements.

[0004] However, the inner layer DF exposure currently uses an LED exposure machine, which needs to use film to complete pattern transfer, and is prone to expansion abnormalities or inner layer pattern offset due to film deformation.
