When procuring semiconductor assembly equipment, you must prioritize Production Speed (UPH - Units Per Hour), typically ranging from 3,000 to 12,000 units depending on the automation level. Ensure the machine supports specific diode types such as Zener, Schottky, or Rectifier diodes. Key technical factors include positioning accuracy (±0.02mm), welding/bonding precision, and compatibility with various lead frame sizes. High-end models should feature CCD visual inspection systems for real-time defect detection.
