laser direct imaging (LDI) system solutions LDI Roll to Roll PCB
LDI is a Laser Direct Imaging technology, which is mainly used in
the exposure process of PCB process. It is different from the
traditional negative contact exposure method. The most remarkable
feature is that the negative is not used in the exposure process,
and the graphics are transferred to the copper-clad laminate coated
with " Photoimaging agent " by using the method of high-energy
laser beam direct scanning.
PCB laser direct imaging (LDI)
When fabricating a circuit board, the circuit traces are defined by
what is the imaging process. Laser direct imaging ( LDI ) exposes
the traces directly with a highly focused laser beam that in NC
controlled, instead of flooded light passing through a photo tool,
a laser beam will digitally create the image.
How does laser direct imaging ( LDI ) work?
Laser direct imaging needs a PCB with the photo-sensitive surface
that is positioned under a computer controlled laser. And then the
computer is creating the image on the board with the light of
laser. A computer scans the board surface into a raster image,
matching the raster image to a pre-loaded CAD or CAM design file
that includes the specifications for the necessary image intended
for the board, the laser is used for directly creating the image on
the board.
