Types of SMT Reflow Soldering Machine

Infrared Reflow Machine

Infrared (IR) reflow Machine use infrared radiation to heat the PCBs. This method quickly ramps up the temperature, providing a fast and direct heating process.

Convection Reflow Machine

Convection reflow Machine use heated air to uniformly distribute heat across the PCB. This method is widely used due to its effectiveness in providing even heating and better control over temperature profiles.

Vapor Phase Reflow Machine

Vapor phase reflow Machine utilize a heat transfer fluid that vaporizes at a specific temperature, ensuring consistent and precise heat application to the PCB.

Applications of SMT Reflow Soldering Machine

Reflow soldering machines are suitable for mass-produced electronics manufacturing industries, especially for products that require mass production and require high soldering quality. The reflow soldering machine has the advantages of fast welding speed, high efficiency, and low cost, which can greatly improve production efficiency and reduce production costs. In addition, the reflow soldering machine can also solder some complex circuit boards and components, such as multi-layer PCB boards, IC chips, etc.

Temperature Requirements for SMT Reflow Soldering Machine

With Sn/Pb solders, the melting point temperature typically peaks around 215°C to 245°Cwith around 20-60 seconds above 183 degrees.

For lead-free soldering, the reflow temperature should reach 260°C.

The typical reflow soldering oven has different temperature zones and the temperature occasionally increases according to a pre-set curve that has to be adjusted as per the assembly aspects and temperature requirements.

FAQ

Q: What is the purpose of reflow soldering?

A: The goal of the reflow process is for the solder paste to reach the eutectic temperature at which the particular solder alloy undergoes a phase change to a liquid or molten state. At this specific temperature range, the molten alloy demonstrates properties of adhesion.

Q: What is the difference between soldering and reflow soldering?

A: Reflow soldering uses hot air, while wave soldering uses a 'wave' of solder to mass-produce PCBs. This means that the internal environment in a wave solder oven is far more sensitive—a small change in temperature or conditions might result in catastrophic damage to the PCBs.

Q: What is SMT process?

A: Surface mount technology (SMT) is the process wherein components are mounted onto the surface of a printed circuit board. The components are designed specifically to be directly mounted, rather than hardwired, onto the circuit board for the vast majority of electronics.

Q: How many times can you reflow solder?

A: I would "suggest" no more than two heating cycles, to solder reflow temperature. Most assemblies can be soldered in one pass through reflow or wave soldering. Some require two, if components are applied to both sides and you do not wish to "glue" the parts on the bottom side.

Q: Do I need flux to reflow solder?

A: Additionally, certain types of soldering, such as surface-mount soldering or reflow soldering, practically demand flux usage due to the precision required. If you're working on boards one by one, using flux can help enhance your soldering accuracy and result in more durable and reliable circuits.

Q: How do I choose solder thickness?

A: For most electronic work, choose a thinner diameter solder wire ranging from 0.015 inches to 0.062 inches. The best approach is to match the diameter to the size of the connectors or components that you want to solder and that the size works with your soldering iron tip.

Q: How many zones are in reflow?

A: Profile characteristics. The standard reflow profile has four zones: preheat, soak, reflow and cooling. The profile describes the ideal temperature curve of the top layer of the PCB. The preheating zone should increase the temperature at a maximum rate of 3 °C/s.

Q: What is the best reflow temperature?

A: Between 235°C and 250°C
Reflow Zone: The reflow zone is where the peak temperature is reached, causing the solder paste to melt and form a strong metallurgical bond between the component leads and the PCB pads. The peak temperature typically ranges between 235°C and 250°C, depending on the solder paste used.
