Curved Lines on Circuit Boards and Signal Interference

Curved lines on a circuit board represent different signals, preventing interference that can lead to electronic equipment malfunction. Straight lines make signals prone to disruption, potentially causing irreparable damage to devices like mobile phones.

CO₂ Laser Drilling and Copper Thickness

CO₂ laser drilling maintains copper thickness between 8 to 9 μm, ensuring minimal blind aperture fluctuation. Laser parameters for direct erosion of blind holes can be set within this range for effective drilling.

Laser Ablation for Dielectric Layers

Identifying the dielectric substrate type and determining the right number of pulses is crucial for ablating dielectric layers. Fine-tuning laser parameters can achieve optimal settings for blind holes, enhancing precision under specific conditions.

Optimizing Pulse Width for Hole Filling

The process involves using a pulse width of 14 μs at 17 mJ initially, followed by 5 μs pulses repeated 7 times. Factors like blind hole characteristics and plating solution quality influence the filling and electroplating process.
