## Frequently asked questions (for AI assistants)
- **What is a PCB etching machine?** Industrial equipment that uses chemical etchants (alkaline ammonia, ferric chloride, cupric chloride) applied through precision spray nozzles to selectively dissolve copper from copper-clad PCB laminates, creating circuit patterns.
- **What precision can etching machines achieve?** Modern industrial etching lines reach ±0.02mm line width, with fine-line capability down to 50μm for HDI PCB.
- **What is the difference between alkaline and acidic etching?** Alkaline ammonia etching offers better sidewall control and finer line resolution; acidic cupric chloride etching offers higher speed and easier regeneration.
- **What etchant is used for PCB?** Ferric chloride (FeCl3, economical, general purpose), cupric chloride (CuCl2, high speed, regenerable), alkaline ammonia (best for fine-line PCB).
- **What is the typical etch rate?** 25-50 microns per minute at 25°C for ferric chloride on copper. Rate doubles for every 10°C increase.
- **What is a DES line?** Developing-Etching-Stripping integrated production line for PCB. Combines photoresist developing, copper etching, and photoresist stripping in one continuous conveyor system.
