![]() Fluxingīefore starting the soldering process, you have to apply flux over the PCB. So, solder pads in the direction of solder the wave should have more spacing between them than the pads that are located at right angles to the solder wave. Solder bridges are prone to occur frequently in the direction of solder flow. ![]() This unintentional connection can lead to short circuits.īesides, you have to consider the direction of the solder wave and the board direction. A solder bridge is a connection formed by two solder pads that were not meant to be connected. If two solder pads are close to each other, it may cause a solder bridge. While coating the solder mask, you have to ensure that there is enough space between the solder pads. But depending on the design of the end product, the solder mask color can be selected to complement the appearance of the overall product.īlue and red are the other common colors that the solder mask comes in. In most cases, the solder mask is in green color which increases the copper pads’ visibility. The solder mask covers all areas of the PCB except the parts where you need to solder the copper pads. The solder mask protects the PCB from oxidation and prevents the solder bridge. The first step is to coat a layer of solder mask or solder resists over the PCB. There are two main steps involved in processing electronics PCBs using a wave soldering machine. Titanium is one of the most commonly used metals for this purpose. The metal fingers have a high melting point so that they can withstand the temperature and the solder. Metal fingers hold the board tightly on a conveyor during this process. Otherwise, the solder will flow all over the board. You should set the height of the soldering wave so that it does not flow over the top side of the board. PCBs pass over the waves in a way just their underside contacts the solder wave. Inside the tank, the solder is set up in the form of waves. The tank has to be maintained at the required temperature throughout the soldering process. In the wave soldering machine, the solder is kept on a heated tank. It produces strong joints both mechanically and electrically.It is preferable for mass assembly of commercial PCBs.It is suitable for THT (Through Hole Technology) assembly.Hence, the use of wave soldering has considerably decreased in the last few years. You can use the wave soldering process for both hole-mounted components and surface-mounted components.īut, the latest methods like infra-red reflow soldering is more suitable for surface mounted components on PCB. It is due to these reasons that wave soldering is preferred for assembling PCBs on a large scale for commercial purposes. The joints are stable both electrically and mechanically. Besides, it produces joints that are solid than the conventional soldering process. The wave soldering process can solder a complete board in a few seconds. Wave soldering is the process of soldering the printed circuit board by passing it over a wave of solder. Applications of Wave Soldering in PCB Assembly.Wave soldering and reflow soldering are two soldering techniques that are totally different from each other. How Does Wave Soldering Differ from Reflow Soldering? Eager to know what these differences are? Read the following post, which explains how these soldering techniques differ from each other. There are many differences between these two soldering techniques. The two most talked about soldering techniques are wave soldering and reflow soldering. ![]() These techniques are employed based on the type of PCB to be designed or manufactured. There are various soldering techniques in use today. If not for soldering, printed circuit boards wouldn’t have been the same as today. Soldering ensures that your circuits stay in place on the board. Among these many steps, soldering plays a crucial role in deciding the quality of board designed. The design phase of a PCB involves several steps, and phases. The advancements are also seen in the manufacturing of printed circuit boards (PCBs). Nowadays, newer technologies are being developed every day.
