High-temperature soldering process is a common and important soldering method, which melts the solder and connects the components on the circuit board by heating them at high temperature, and is used to realize a reliable solder connection.
Definition
High-temperature soldering is a soldering method in which the solder is heated at a high temperature to melt and form a connection with the components on the surface of the PCB. High-temperature soldering typically uses a furnace or heating equipment to heat the soldering area to a high enough temperature to melt the solder and form a solder joint.
Working Principle
The high-temperature soldering process works by heating the solder at a high temperature, causing it to melt into a liquid state, where it makes contact with the components on the circuit board and forms a solder joint. Soldering temperatures typically range from 200°C to 400°C, depending on the solder material and component type.
Application Scenarios
High temperature soldering process is widely used in various aspects of PCBA processing, including but not limited to:
1. SMT soldering
for surface mount technology (SMT) component soldering, such as chips, capacitors, resistors and so on.
2. Plug-in component welding
used for plug-in component welding, such as sockets, switches, etc.
3. Reflow soldering process
for soldering connections of multi-layer PCB boards by high temperature soldering.
Advantages
1. High-quality welding
High-temperature welding process can realize high-quality welding connections with even and firm welding joints.
2. Wide range of application
