Various types of reflow soldering equipment introduction

Reflow soldering is an important process in Surface Mount Technology (SMT) for soldering Surface Mounted Devices (SMDs) onto PCBs (Printed Circuit Boards). Reflow equipment is one of the key equipment for realising this process. The following is an introduction to the various types of reflow soldering equipment:

1. Conventional Wave Soldering Reflow Oven (Wave Soldering Reflow Oven):

Traditional wave soldering reflow oven is suitable for high-volume PCB soldering, the entire PCB through the preheating zone, soldering zone and cooling zone, to achieve welding.

This reflow oven is usually used for welding larger electronic components or plug-in components, for small SMD components welding is not precise enough.

Traditional wave soldering reflow furnace is mainly used in the traditional electronics manufacturing industry, high welding efficiency, but the SMD component welding precision requirements are not high.

2. Hot air reflow oven (Hot Air Reflow Oven):

Hot air reflow oven through the preheating area, welding area and cooling area of the hot air cycle, to achieve precise welding of SMD components on the PCB.

Hot air reflow ovens are widely used in most SMT production lines for their ability to provide precise temperature control and solder quality.

These reflow ovens are suitable for soldering small SMD components and are the main soldering equipment in modern SMT production lines.

3. Infrared Reflow Oven:

Infrared reflow oven using infrared as a heat source, to achieve the PCB SMD components on the welding, for some special types of components.

Infrared reflow oven used in some of the higher temperature control requirements of the occasion, you can quickly and evenly heat the components to avoid the impact of thermal inertia.

4. Convection reflow oven (Convection Reflow Oven):

Convection Reflow Oven uses convection hot air to transfer heat evenly to the SMD components on the PCB to achieve welding.

This reflow oven is suitable for soldering on the PCB has high requirements for temperature uniformity, and is suitable for soldering a large number of small SMD components.

Convection reflow oven with better temperature control and uniformity, is one of the modern SMT production of commonly used welding equipment.

5. Specialised reflow machine (Specialized Reflow Oven):

In addition to the above several common reflow oven, there are some according to the specific requirements of the design of the special reflow machine, such as nitrogen protection reflow oven, ultraviolet reflow oven, etc..

These dedicated reflow machines are usually used for special PCB soldering needs, providing a more customised soldering solution.

Reflow soldering equipment plays a vital role in the SMT production line. Selecting the right type and size of reflow soldering equipment is essential to ensure soldering quality and productivity. Depending on production requirements and component types, choosing the right reflow soldering equipment can improve productivity, reduce soldering failure rates and ensure product quality.
