Selective wave soldering is an efficient and precise soldering technology based on the fundamental principle of wave soldering, but it achieves selective heating and soldering of specific areas by controlling the shape and position of the solder wave. In selective wave soldering, soldering material is pre-coated with flux onto the workpiece, which is then placed…

Firstly, in terms of application, wave soldering is mainly used for mass production, such as in electronic device manufacturing, where large quantities of connections need to be soldered. Selective wave soldering, on the other hand, is more suitable for small-batch production and specific component soldering, such as circuit board repair and assembly. Secondly, wave soldering…

Selective wave soldering utilizes nitrogen gas primarily for the following reasons: It is important to note that the use of nitrogen gas should consider factors such as cost and safety. Some electronic components or assemblies may not be suitable for nitrogen-rich environments. Therefore, the decision to use nitrogen gas in selective wave soldering should be…

The occurrence of solder bridging in selective wave soldering may be attributed to various factors. Here are some possible solutions: Please note that specific solutions may vary depending on the situation. It is advisable to consult with professionals or equipment manufacturers for more detailed advice tailored to your specific circumstances.

The lifespan of selective wave soldering nozzles depends on several factors, including the following: Please note that the above factors are general considerations, and the specific lifespan may vary depending on factors such as equipment model and process requirements.

Using Selective Wave Soldering (SWS) can save resources and costs in the following aspects: In summary, using Selective Wave Soldering can save materials such as fixtures, nozzles, and solder, reduce energy consumption, lower labor costs, and optimize soldering precision and efficiency. These savings will have a positive impact on production costs and resource management.

The purity of nitrogen used in selective wave soldering typically needs to be above 99.99%. This high level of purity is necessary to effectively reduce the oxygen content, thereby minimizing the oxidation of molten metal and ensuring soldering quality. However, the specific requirements for nitrogen purity may vary depending on factors such as the materials…

When it comes to double-sided PCB assembly, selective wave soldering offers both advantages and disadvantages compared to traditional through-hole wave soldering. Let’s explore them: Advantages: Additionally, selective soldering can handle circuit boards that cannot be wave soldered, such as those with high-PTH components on both sides. This is a highly beneficial feature as, previously, the…
