YH853A Preheater for BGA Rework Stations (PCB Preheater) Stable airflow and long life Uses special air conduction and an AC power supply with no carbon brushes, helping the airflow stay constant during cooling or preheating and extending overall service life. Convenient digital control Digital control with easytouse timer/set options for precise and repeatable heating performance. Durable stainless steel platform Platform is made of stainless steel for corrosion resistance and reliable operation over time. Energy efficient lowtemperature preheating Preheating at low temperature saves energy, while the design protects components from damage during lowtemperature preheating. Use scenarios BGA rework preparation Preheat PCBs to reduce thermal stress before soldering, improving yield and board integrity. Large or multilayer boards Use for uniform preheating of larger PCBs to minimize warpage and ensure consistent soldering results. Postrework cooling After rework, use controlled airflow to cool the board safely and protect sensitive components from rapid temperature change. This model (YH853A) provides reliable preheating and cooling support for BGA rework workflows, combining stable airflow, precise digital control, a durable stainless steel platform, and energyconscious operation.
