For additional information, please contact Highlywin to obtain:
- Second-hand equipment refurbishment inspection report (including precision calibration data).
- 3D simulation of dual-track production layout.
- Hybrid process validation cases (smartphone motherboards + automotive electronic modules).
This solution balances cost and quality; second-hand pick-and-place equipment can reduce initial investment, while the intelligent detection system ensures compliance with throughput rates. It is recommended that customers prioritize the layout of pick-and-place machines and SPI inspection stations while applying for environmental certification simultaneously.
