History: 

The history of direct laser imaging in printed circuit boards (PCBs) goes back to the early 1990s when the first commercial systems were introduced. These systems were based on using a laser to “draw” the desired circuit pattern on a photosensitive substrate. The exposed substrate is then developed and etched to create the desired circuit. 

Laser direct imaging systems quickly became the preferred method for creating high-density PCBs due to their superior accuracy and resolution. Today, most PCB manufacturers use laser-direct imaging systems to create the desired circuit patterns on their boards.

How does Laser Direct Imaging (LDI) work in PCB?

Laser Direct Imaging (LDI) is a technology that utilizes a laser to expose the desired image onto the substrate directly. This technology is commonly used to produce printed circuit boards (PCBs). To create the desired image, the laser selectively removes material from the substrate. This process is known as laser ablation.

LDI is a process of creating images on a PCB using a laser. It is a direct imaging process, meaning the image is created directly on the PCB without needing a film or mask. This makes LDI ideal for creating small, complex, or high-density images on a PCB. If you are considering using LDI to create images on your PCBs, remember a few things. 

  1. First, LDI is a very precise process, so it is essential to have accurate artwork.
  2. Second, LDI is best suited for creating small, simple images. If you need to create a large or complex image, there may be better options than LDI.
  3. Finally, LDI is a relatively new technology, so it is essential to work with a manufacturer that has experience with this process.

LDI is an exact and accurate method of creating images on substrates. It can create very fine details and is often used when high levels of accuracy are required. LDI is also a very fast imaging method, making it ideal for mass production. 

There are a few disadvantages to LDI. One is that it can be expensive since it requires specialized equipment. Additionally, LDI is only sometimes compatible with all types of substrates.
