Technical terms (e.g., "defect names", "passable grade") are translated accurately to maintain industry standard terminology. 2. Quantitative specifications (e.g., "3% of the board surface") are converted to English units while retaining the original meaning. 3. Geometric terms (e.g., "length ≤100 mm") are translated with clarity to ensure readability. 4. Repetitive structures (e.g., "not allowed") are standardized for consistency. 5. Special characters (e.g., ≤3 mm2) are rendered using appropriate symbols (≤) to preserve formattin
