Aluminum PCB Reflow Heater

Overview

The Aluminum PCB Reflow Heater is a compact and efficient device designed for solder reflow applications, making it an ideal solution for hobbyists, makers, and small-scale electronics enthusiasts. This versatile heater requires only an adjustable DC power supply, providing a cost-effective and user-friendly alternative to traditional reflow ovens.

Specifications

• Input Voltage: DC or AC 24V-30V (Dependent on power and temperature)
• Power Consumption: 60 - 100 W (Dependent on temperature)
• Heating element resistance: ≈3.4Ω
• Temperature Range: Adjustable based on user preferences (typically 150°C to 250°C)
• Heating Element: Aluminum PCB with embedded heating elements

Setup Instructions

1. Power Supply Connection: Connect the Aluminum PCB Reflow Heater to a compatible adjustable DC power supply using the smd solder pads for wires.

2. Voltage Setting: Set the desired voltage on the dc power supply and measure the temperature using a thermocouple or an infrared thermometer. Ensure that the temperature range is appropriate for the solder paste being used.

3. Preheat: Allow the device to preheat until it reaches the required temperature.

4. Reflow Process: Once preheated, carefully place the PCB with solder paste onto the heater surface..

5. Cool Down: After completing the reflow process, allow the PCB to cool down naturally before handling.
