PCBA components boards, having undergone processes such as SMT reflow soldering, DIP wave soldering, or selective wave soldering, invariably contain residues of flux and solder paste. Despite the term “no-clean” associated with modern electronic chemicals such as solder paste and flux, it does not indicate the quantity of residues left on the PCBA components board…
Flux is one of the most critical auxiliary materials in the electronics industry, directly affecting the quality and stability of electronic product assembly processes. With the rapid development of the modern information electronics industry, the demand for flux has increased significantly, raising the standards for flux selection. Flux mainly consists of activators, solvents, surfactants, and…
PCBA stands for Printed Circuit Board Assembly. It refers to the process of assembling various electronic components onto a PCB (Printed Circuit Board) using surface mount technology (SMT). Once the PCB is assembled with components, it is then assembled with other parts such as the casing to form the final product. In other words, PCBA…
Selective wave soldering machine equipment has been invented for over 50 years now and has been crucial in the automated mass production of electronic devices, particularly for soldering through-hole components on circuit boards, offering high production efficiency and automation levels. With the emergence of various surface-mounted component packaging forms in recent years due to the…
The configuration of selective wave soldering production lines can be classified into various categories. This article will discuss the configuration of selective wave soldering production lines using the concept of modules. Apart from standardized wave soldering, there are many different types of fluxing, preheating, and soldering methods for other machine soldering processes. Let’s briefly introduce…
Selective wave soldering is a specialized form of wave soldering that has emerged to meet the requirements of modern welding processes, particularly prevalent in PCBA manufacturing. It primarily consists of three components: fluxing unit, preheating unit, and soldering unit. Components of Selective Wave Soldering Equipment: Welding Methods of Selective Wave Soldering: I hope this helps!…
These are the reasons for selective wave soldering bridging. We hope this information is helpful to you. If you have any further questions or need clarification, please feel free to contact us.
In PCBA processing, there are two types of processing technologies for through-hole components: selective wave soldering and manual soldering. So, what are the differences between these two soldering methods, and what are their respective advantages and disadvantages? Let’s explore the differences between selective wave soldering and manual soldering. From the perspective of soldering quality, selective…
Why use selective wave soldering? Undoubtedly, selective soldering offers many advantages, such as improved solder joint quality and aesthetics, reduced oxidation, and more. But why choose it? In other words, what issues cannot be addressed without using this selective soldering method? This tells us that the main reason for adopting selective soldering is the quality…
Selective soldering is a soldering process that targets specific areas of a PCB (Printed Circuit Board) without affecting the entire surface or all electronic components on the board. During selective soldering, the PCB is first fixed within a frame, and all subsequent operations are automatically controlled by a pre-programmed process in the automated control system.…
