IV.
Selection Criteria
First, component size (01005–0201); second, precision (±0.025mm); third, cycle time (points/hour); fourth, fixtures (customization); fifth, inspection (AOI/ICT/FCT)—Selection: Component type + precision + cycle time (prioritize verifying placement yield).
V. Supplier Evaluation
Key factors include: Track Record (major 3C manufacturers); Specialization/Innovation (qualifications); End-to-End Process (from SMT to final assembly); Prototyping (small-batch runs);
and After-sales Support (on-site commissioning)—Evaluation focus: Track record + end-to-end process + prototyping (small-component acceptance yield).
VI. Trends
AI: AI-driven visual inspection; Flexibility: Rapid changeover for diverse product mixes; Miniaturization: SiP/advanced packaging (Source: Sankechuang); Global Expansion: Production shifting to Vietnam/India while equipment originates from China (Source: Weibo);
Cleanliness: Apple-standard cleanrooms (Source: Toutiao)—Trends: AI + flexibility + miniaturization (increasing precision for small components).
VII. Procurement Recommendations
Recommendations: Equipment—choose Yuehe or Xinsilu; Contract Manufacturing—choose Sankechuang or Juchuan (01005 component capability); Prototyping/Validation—start with small batches; Acceptance—verify placement accuracy and yield;
Flexibility—ensure capability for multi-product changeovers—3C small-component assembly: Yuehe/Xinsilu equipment and Sankechuang/Juchuan contract manufacturing (dual verification of micron-level precision and 01005 component capability).
