WebOct 27, 2024 · How does LDI work? Laser direct imaging requires a photo-sensitive surface that is positioned under a computer controlled laser. Then the computer generates the image on the board, via the laser’s light. The process typically goes as follows: 1. Coat resist on the copper laminate 2. Photo of the circuit pattern is then exposed onto the resist 3. WebThe light is channeled through the a-Si photodiode layer where it is converted to a digital output signal. The digital signal is then read out by thin film transistors (TFTs) or fiber-coupled CCDs. [3] 2. Direct FPDs. Amorphous selenium (a-Se) FPDs are known as “direct” detectors because X-ray photons are converted directly into charge.
