Using the American HELLER hot air circulation heating method, efficient pressurized accelerating air duct, greatly improve the circulation of hot air flow, rapid heating (about 20 minutes), high heat compensation efficiency, can be high temperature welding and curing; Each temperature zone is equipped with an independent temperature sensor to monitor and compensate the temperature balance of each temperature zone in real time; Special pressurized air structure and special-shaped heating wire design, no noise, no vibration, with a very high heat exchange rate, the temperature difference between the BGA bottom and the PCB board is very small, more in line with the strict requirements of the lead-free process, especially for the difficult welding requirements of lead-free products.
