Post Welding | SMT Soldering | PCB soldering

First, what is post-soldering processing
Post-soldering processing refers to the circuit board in the wave soldering, for some components that are not suitable for wave soldering, by using a soldering iron for manual soldering.
Second, the need for post-soldering processing reasons
1, components do not resist high temperature
Today, lead-free technology is becoming more and more popular. When soldering by wave soldering, the temperature in the furnace is higher than the temperature of lead. Therefore, some components that are not resistant to high temperature cannot be soldered by wave soldering.
2、Components are too high
Wave soldering on the height of the component is also limited, the component will be too high to lead to not pass the wave soldering.
3, there are a small number of plug-ins in the side of the wave crest
In a circuit board, the side of the wave soldering will have some plug-ins, if a small number of plug-ins, you can use the post-soldering process to improve efficiency.
4, component plug-ins near the edge of the process
Component plug-in position near the edge of the board will touch the assembly line, affecting the normal welding.
5、Special components
For customers with special requirements of high sensitivity components, can not be over the wave soldering.
Post welding refers to the processes and treatments applied to a welded joint after the welding operation is complete. While welding joins materials together, it often introduces certain defects or undesirable properties that can compromise the integrity or performance of the welded structure.
Post welding procedures may include heat treatment, surface finishing, inspection, and quality assurance measures. These steps are crucial for minimizing defects, improving mechanical properties, and meeting the required standards and specifications. By carefully implementing post welding procedures, manufacturers can achieve high-quality welds that meet the demands of various industries, from construction and automotive to aerospace and beyond.
