A Comprehensive Guide to LED Exposure Machines in China
LED exposure machines are crucial in various industries, particularly in printed circuit board (PCB) manufacturing and flexographic printing. China is a significant manufacturer and exporter of these machines, offering a wide range of options for different applications and budgets. This guide explores the technical features, types, and key considerations when choosing an LED exposure machine from Chinese suppliers.
Understanding LED Exposure Machines
LED exposure machines utilize ultraviolet (UV) light-emitting diodes (LEDs) to expose photosensitive materials, transferring circuit patterns onto PCBs or images onto printing plates. The process involves placing a photomask (a transparent sheet with the desired pattern) over the photosensitive material and exposing it to UV light. The exposed areas harden, while unexposed areas remain soluble, allowing for the development of the circuit or image. Companies like Huaxing (www.huaxingflexo.com) specialize in LED exposure machines for flexographic printing plates, while XGH Tech (www.xghtech.com) focuses on PCB applications.
