laser direct imaging (LDI) system solutions PCB Solder Mask
Difference between LDI and traditional exposure
1. Traditional exposure is to transfer the image to PCB by irradiating the negative with a mercury lamp
2. LDI uses the laser scanning method to directly image the image on PCB, and the image is finer
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.
