The SMT Conveyor with cold air hood is a critical temperature control device in electronic manufacturing production lines, primarily used to rapidly reduce PCB board temperature and stabilise the transfer environment. Its core functions and value are as follows: Core functions: active heat dissipation and temperature control 1. Forced air cooling Equipped with a high-efficiency fan system, it rapidly removes residual heat from PCB boards after reflow soldering through forced convection. Typically, it reduces board temperature from above 200°C to the safe range of 40-60°C within 1-2 minutes, preventing high temperatures from affecting subsequent processes (such as AOI inspection and component insertion). Compared to natural cooling, efficiency is improved by over 50%, significantly reducing production cycle times and meeting the demands of high-speed production lines.
2. Temperature Uniformity Assurance A multi-fan matrix layout combined with airflow channel design (such as the 90° directed airflow structure mentioned in the patent) ensures uniform heating of the PCB surface, preventing component damage caused by local temperature differences.
