.... It is shown that the ablation rates per pulse are much higher when compared with those at 248nm. The crater diameter increases monotonically with the pulse energy. However, when the pulse energy is very high and the power density is higher than 4.0 × 10⁹W/cm², the crater depth...

... Aramid reinforced laminates using laser ablation technology. Laser equipment capable of producing over 100 blind micro‐via holes per second is discussed. The process steps of hole cleaning and plating are reviewed, showing how existing PWB manufacturing technologies can be used. This process is compared...
