Atten ST-7500 Preheating & Reflow Platform Hot Plate

If you’ve ever encountered the intricate task of mounting SMD components, or even trickier, the delicate process of removing components from PCBs, you’ll know that it can be quite a challenge, if not impossible using a soldering iron. That’s where a hot plate such as the ST-7500 comes in handy. Armed with the ST-7500 and some solder paste, tackling SMD components becomes a breeze. Removing components too, with a bit of luck also becomes easier. It’s simply a case of heating up the PCB and then using tweezer to lift the components away from the board. The ST-7500 can also be used for other professional applications, such as mobile phone screen disassembly and in science and education for pre-heating materials.

The ST-7500 makes use of an infrared ceramic heating element and can operate between 50°C-500°C. Temperature control is easy and three presets are available for added convenience. The unit has a clear display showing the operating temperature. The ST-7500 comes with a thermocouple sensor, allowing users to measure the actual temperature reached in the heated job.

The ST-7500 work area measures 120x120mm. Available as an optional extra, Atten sell the ST-701 platform support. This stand device allows you to move the work job over the heating area with precision.

Features:

• Adjustable heating temperature range from 50℃ to 500℃
• Intelligent temperature closed PID control, achieving precise constant temperature operation.
• Supports temperature compensation & adjustment
• Three preset temperature controls for quick temperature switching
• OLED display
• Anti static design
• Can be used for preheating circuit boards and other processes that require uniform heating
• Equipped with an external K-type sensor interface, convenient for testing the actual temperature of heated job
• With RS485 Communication (Slave Mode) interface for computer control

Please be careful when using this device. Treat a Hot Plate as though it was an open flame. Do not leave unattended.

The basic process for soldering a PCB that has SMT parts (source https://reprap.org/wiki/HotplateReflowTechnique – more info here):

• 1. Apply Solder Paste to all the SMT pads.
• 2. Place all SMT components in the appropriate place.
• 3. Heat up the entire board to melt the solder and solder all parts simultaneously.
• 4. After the board has cooled, fix any solder bridges.
• 5. Solder in the remaining through-hole parts, if any.
