Advantages of wave soldering: 1. suitable for THT assembly; 2. more time-saving; 3. reduce warpage; 4. low cost; 5. can provide high-quality solder joints; 6. suitable for through-hole soldering
What is the difference between reflow soldering and wave soldering?
1. Different working principles
Reflow Soldering: In reflow soldering, components are mounted on a PCB and then adhered using solder paste, which is then placed in a reflow oven, where the solder paste is heated to the melting point by controlling the temperature profile and allowed to re-solidify and complete the soldering.
Wave Soldering: PCBs that have been fitted with electronic components are moved by a conveyor belt to a wave soldering machine. The wave of solder impacts the soldering area through specific nozzles to realize the soldering.
2. Different usage scenarios
Reflow soldering: Reflow soldering is usually used for SMT assembly.
Wave soldering: Wave soldering is mainly used for plug-in assembly.
3. Soldering needs are different
Reflow soldering: Provide higher welding quality, because it can control the temperature profile, so you can avoid too hot and lead to component damage.
Wave soldering: generates high heat during the soldering process, which may cause damage to temperature-sensitive components.
4. Soldering complexity is different
Reflow soldering: more complex equipment and control systems to control the correct temperature profile and parameters.
Wave soldering: Wave soldering is relatively simple, only need to adjust the welding parameters and speed of the wave soldering machine.
Whether it is reflow soldering or wave soldering, each has its own advantages, to deal with different products and applications, will use different process technology to achieve the best results, reflow soldering and wave soldering is an important step in the PCB assembly process can not be missing.
