UV exposure machine basics
- May 12, 2018 -

Ultraviolet exposure machines, also known as lithography machines, mask alignment exposure machines, exposure systems, lithography systems, etc., are important devices in the manufacturing process of printed circuit boards (PCBs). The general lithography process is subject to processes such as cleaning, drying, coating, spin coating, soft bake, alignment exposure, post-baking, developing, hard-baking, and etching. Its main performance indicators are: support for the size of the substrate range, resolution, alignment accuracy, exposure mode, light source wavelength, light intensity uniformity, production efficiency.
