laser direct imaging (LDI) system solutions HDI PCB
Technical advantages of LDI
(1) LDI technology adopts laser positioning and vertical laser beam
scanning, which can ensure that the graphic position deviation is
within ± 5um, which greatly improves the line alignment accuracy
and position.
(2) LDI technology does not use negative film, which can meet the
production of very high-density fine conductors, improve the
qualification rate of fine line PCB manufacturing and avoid
repeated positioning defects.
(3) LDI technology does not need to manufacture, preserve and
maintain photographic film devices, consumed materials, energy,
other auxiliary materials, and chemicals, which reduces the
production and processing cost.
(4) LDI technology can shorten the PCB manufacturing process,
reduce the turnaround time, improve the rapid response-ability,
reduce the intervention of human factors, simplify the operation
process, and then improve the production efficiency.
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.
