The quality and precision of printed circuit board depend on the exposure quality to a large extent. Within the effective exposure area of ​​the illuminated table, the parallelism and energy uniformity of ultraviolet light determine the exposure quality of the system. The exposure light source of the exposure machine is divided into scattered light and parallel light. In fact, there is no completely ideal parallel light exposure machine, but we often use the incident angle and scattering angle of the exposure machine light source to determine the performance of the exposure machine. Generally, the definition of a parallel light exposure machine is that the angle between the incident angle and the scattering angle is ≤3°.
