The Atten ST-7322 is a preheater with a 4-quadrant architecture. Each quadrant, with a size of 200x180mm, can be controlled independently. This preheater is able to draw up to 4600W (three-phase 380V), and with a total heating surface of 4x200x180 mm, it is suitable for most preheating jobs, and when combined, even larger PCBs. With an external K-type thermocouple, you can easily measure the temperature of the PCB. There are in total 4 connectors available on the pre-heater, one for each heating surface. Moreover, the preheater has a 2.4' TFT color display, showing operating temperatures and power for each channel. With the graph view, you can easily track how each channel progresses over time.
The preheater is ideal for reworking PCBs. With a working temperature from 50 - 250 °C, some bigger PCBs might need an additional heat gun. Finally, the preheater has several optional additions, such as the H-11 base plate, which serves as a holder for the ST-862D heat gun. Another option is the ST-704, a support stand that securely attaches PCBs to the preheater.
