LDI for production summary

With the increasingly strict and precise alignment requirements, it is necessary to replace the traditional exposure methods. The latest developments in LDI technology, such as all requirements on mass production, can be achieved through LDI, including accuracy, output, automatic control, and traceability.

Although mass production of HDI boards requires high acquisition costs to purchase LDI equipment, the growing team of HDI manufacturers is now using the LDI system as the imaging method of the mass production line. The reason is simple: these manufacturers have confirmed that LDI has increased their production by at least 3% on some more complex HDI boards, and the result is that they can recover their investment within a year.

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.
