Buyers must prioritize Bonding Accuracy (typically ±2.0μm to ±3.0μm) and Uph (Units Per Hour) to ensure high-yield semiconductor assembly. Key components include the Transducer frequency (usually 60kHz to 130kHz), the XY stage resolution, and the Vision System's capability to handle PR (Pattern Recognition) for complex lead frames. Ensure the machine supports the specific wire types you use, such as Gold (Au), Silver (Ag), or Copper (Cu) wire, as each requires different capillary types and gas shielding (e.g., Forming Gas for Copper).
