The Preheater ST-7800 is a small, but powerful preheating heater solution for precision electronics repair/rework applications. The advanced aluminium heating plate provides even heat around the plate making it suitable for working with delicate circuit boards without the risk of thermal damage or warping. With a powerful 800W heating system, the ST-7800 delivers fast temperature ramp-up and stable performance throughout the operation. It features a self-controlled PID temperature control system that is able to monitor and adjust the heat continuously to achieve high accuracy and consistency. This sort of control is needed for fragile packages like BGA, QFN and SMD packages.

The unit has a convenient digital readout for setting and checking temperature. It also can accommodate an external K-type thermocouple for real-time temperature measurement of the actual PCB for more precise rework operations. Because of its small size and relatively small heating area, it can be used for small to medium boards, such as consumer electronics, LED modules and industrial control systems. The ST-7800 is designed to be durable and easy to use, and is commonly used in service centers, repair labs, and manufacturing setups. This not only improves the quality of soldering but also helps prevent damage to the PCB and increases overall efficiency, making it a valuable tool for professionals looking for consistent and quality results.
