A Controlled Process for
Reliable Soldering.
Consistent soldering starts with proper preparation, controlled paste application, accurate component placement, and appropriate heat management. Adjust your process according to the PCB, component, equipment, and specific repair procedure.
Prepare the Surface
Make sure the PCB pads and soldering area are clean and properly prepared before applying solder paste.
Apply the Paste
Dispense a controlled amount of solder paste onto the intended pads or soldering area. Avoid applying more material than the joint requires.
Align the Component
Carefully position the component and verify alignment with the PCB pads before beginning the heating process.
Apply Controlled Heat
Apply heat appropriate for the component and PCB until the solder reaches proper reflow. Avoid unnecessary or prolonged heat exposure.
Cool & Inspect
Allow the assembly to cool naturally, then inspect the component alignment and solder joints before returning the device to service.
The 183°C melting point describes the Sn63/Pb37 alloy and is not a universal hot-air, soldering iron, or reflow temperature setting. Actual equipment settings will vary with PCB thermal mass, component size, airflow, heat transfer, and the repair process.
