LDI exposure platform and its principle
A laser Direct imaging (LDI) exposure machine is a device used to manufacture printed circuit boards that uses a laser beam to project a circuit pattern onto a photosensitive material to form a pattern of the circuit board. LDI exposure machine has the characteristics of high precision, high speed and high efficiency, which can greatly improve the quality and production efficiency of circuit board manufacturing. At the same time, it can also realize the manufacture of multi-layer circuit boards to meet the needs of different customers.
