High-Precision LED Exposure Equipment: Improve PCB Yield with Uniform UV Light Source

For electronic manufacturers, product yield is directly related to profit margins. Traditional mercury lamp exposure machines often have problems such as uneven light intensity, unstable wavelength, and large light decay, which lead to blurred edges of circuit patterns, inconsistent line widths, and even short circuits and open circuits of products. These defects not only waste raw materials but also affect the reputation of enterprises in the global market.
Our LED energy-saving screen exposure machine solves the problem of low yield from the source with advanced optical technology. The equipment adopts a UV-LED parallel cold light source with a single wavelength (365nm/395nm), which ensures stable light output and uniform light intensity distribution, with a uniformity of more than 95% <superscript:3>. This precise light control can realize fine line exposure with a resolution of up to 50μm and a line width tolerance of ±0.02mm <superscript:4>, ensuring that each circuit pattern is clear and consistent.
In addition, the LED light source of the equipment has little light decay and stable performance during long-term use. The light decay rate is less than 10% after 20,000 hours of use, while the light decay of traditional mercury lamps will exceed 30% after only 1,000-2,000 hours <superscript:5>. This stability avoids the problem of reduced yield caused by light source aging, and ensures consistent product quality in mass production.
Whether it is the inner layer, outer layer, or solder mask exposure of PCB, or the precision processing of FPC flexible circuit boards and OLED displays, our LED energy-saving screen exposure machine can meet the high-precision requirements of different products. A number of customers in Europe and the United States have increased their product yield by 15%-25% after using our equipment, greatly reducing the loss of defective products.
