Description
The YIHUA 946D-IV Mini Preheater is a specialized heating table that provides a stable, uniform thermal base for delicate electronics repair. Unlike larger screen separators (like the 946D-III), the IV-series is optimized for a "mini" footprint, making it ideal for mobile phone motherboard repair and hobbyist workstations where space is at a premium.
It utilizes an aluminum heating plate known for its excellent thermal conductivity and flatness. Controlled by a high-precision PID microcomputer, the station maintains a consistent surface temperature with minimal deviation, protecting sensitive components from thermal shock or overheating often caused by direct hot air gun use alone.
Features
PID Precision Control: Employs a Proportional-Integral-Derivative (PID) algorithm to monitor and stabilize the plate temperature in real-time.
Rapid Heating: The high-efficiency aluminum plate can reach working temperatures (e.g., 300°C) in under two minutes.
Safety Housing: Features a full-metal protective surround to prevent accidental contact with the heating element during operation.
Digital Calibration: Includes a digital LED display for accurate temperature monitoring and a °C/°F toggle for international unit compatibility.
ESD-Safe Design: Engineered with a panel-to-ground resistance of less than 2 to prevent static discharge from damaging sensitive ICs.
