pplication Fields of MWSU333B 385NM
NICHIA MWSU333B 385nm is a top-tier single-chip UV LED with 20W high power, rated at 3.7V and 6000mA. It serves as the core light source module for PCB Laser Direct Imaging (LDI) exposure machines.
Laser Direct Imaging (LDI) is critical equipment in PCB manufacturing, utilized for exposing dry film, wet film and solder mask ink.
"6LED" means the light source module consists of six independently controlled high-power UV LEDs; "unlink" indicates the six LED channels adopt independent driving circuits.

The six LEDs on the module emit 385nm ultraviolet light and come with a water-cooled heat dissipation structure. As the light source unit of LDI exposure machines, they deliver high-intensity and stable UV exposure energy for PCB photosensitive materials. Its primary application is LDI exposure equipment for PCB production.
