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…

Understanding the characteristics of selective soldering can be gleaned through a comparison with wave soldering. The most significant difference between the two lies in how the PCB is treated during soldering. In wave soldering, the bottom part of the PCB is entirely immersed in liquid solder, whereas in selective soldering, only specific areas of the…

Selective wave soldering offers several advantages over traditional wave soldering: A. Reduced Energy Waste and Oxidation Reactions Selective wave soldering allows targeted heating only on the areas requiring soldering, minimizing heat wastage in surrounding regions and reducing energy consumption. Additionally, it reduces the occurrence of oxidation reactions by limiting the exposure of soldering areas to…

The main differences between selective wave soldering and wave soldering lie in the soldering method and application fields. Selective wave soldering is a method of selectively heating the soldering area by controlling the size and shape of the soldering head. This method is commonly used for soldering electronic components such as Surface Mount Technology (SMT)…

Selective wave soldering is an efficient and precise soldering technique. It employs positioning devices and control systems during the soldering process to confine the soldering area to the desired parts. This method enhances soldering quality, reduces energy consumption, and improves production efficiency. Selective wave soldering is commonly used in the production of electronic components, automobiles,…
