What is a SMT reflow oven?
An SMT reflow oven is a machine used in the Surface Mount Technology (SMT) process to solder components onto a printed circuit board (PCB). It uses controlled heat to melt the solder paste applied to the PCB, bonding the components to the board.
Types of SMT Reflow Oven – Choose the Right Reflow Soldering Solution
Reflow soldering ovens are essential for ensuring reliable and precise solder joints in PCB assembly. Depending on your production scale, component types, and application needs, there are various types of reflow ovens to choose from. Below, we’ll guide you through the most common types and their unique features to help you make an informed decision.
Features: Reduce oxidation, improve wettability, improve lead-free soldering, reduce defects
Applicable scenarios: lead-free soldering, high-precision PCB, medical equipment
Features: Eliminate voids, high welding strength, suitable for high-power equipment, low oxidation
Applicable scenarios: aerospace, LED modules, power electronics
What is the reflow temperature for SMT?
Preheat Zone: 150–180°C (302–356°F) – Gradual heating to prevent thermal shock and activate flux.
Soak Zone: 180–200°C (356–392°F) – Flux activation and preparation of solder paste for reflow.
Reflow Peak Temperature: 220–250°C (428–482°F) – The solder paste melts and forms strong bonds between components and the PCB.
Cooling Zone: Below 200°C (392°F) – Gradual cooling to solidify the solder joints.
What is the process of reflow oven?
Loading: The PCB with solder paste and components is loaded into the reflow oven.
Preheating: The oven gradually heats the PCB to a low temperature to avoid thermal shock and activate the flux in the solder paste.
Soaking: The PCB stays at a steady temperature to allow the flux to fully activate and prepare the solder for melting.
Reflow: The temperature is raised to the peak, where the solder paste melts, and the components are securely attached to the PCB.
Cooling: The PCB is cooled gradually, allowing the solder to solidify and form strong, reliable joints.
Unloading: The completed PCB is removed from the oven after cooling, ready for inspection or further processing.
