In the "true" theory of soldering, we incorporate the results of many years of unique research, including a proprietary solder feeding mechanism, high-speed design through lightweight robot arms, and tip units tailored to the workpiece. As an example of this theory, we introduce the "functions unique to dedicated robots." Features include a teaching BOX function and Win app replacement and search functions. The solder dispensing automatically performs appropriate solder retraction, so only the amount of solder to be melted needs to be set. 【Teaching BOX Function Overview】 ■ Dynamic Editor - Real-time updates of solder amount, preheating and heating times via BOX operation. ■ Pitch Copy - Simplification of settings for workpieces at equal intervals (conditions for the first and last points + total count). *For more details, please refer to the PDF materials or feel free to contact us.

In the "true" theory of soldering, we incorporate the results of years of unique research, including a proprietary solder feeding mechanism, high-speed design through lightweight robotic arms, and tip units tailored to the workpiece. As an example of this theory, we introduce the "fixed tip angle." The comprehensive capabilities of the dedicated robot enable the fixation of the tip angle. By simply changing the cut surface of the tip, it becomes possible to control the flow of solder. [Overview] ■ Tip angle: Approximately 60° ■ Tip types: 800 varieties ■ Solder and flux remain active on the tip ■ By merely changing the cut surface of the tip, solder flow control is possible *For more details, please refer to the PDF materials or feel free to contact us.

In the industry, it is commonly believed that the cause of "pad red eye defects" is due to misalignment of the soldering iron tip position. However, our perspective is completely opposite to that notion. This is because, in manual soldering performed by operators, the position of the soldering iron tip varies slightly each time, yet red eye defects do not occur. This proves that misalignment of the soldering iron tip position is not the direct cause. The cause of red eye defects is that insufficiently performing robots are unable to achieve soldering at the "optimal timing," resulting in inadequate solder wetting. *For more details, please refer to the PDF materials or feel free to contact us.*

In industry common sense, using nitrogen gas in soldering is considered beneficial for improving solderability. However, in our view, the advantages of nitrogen can be sufficiently obtained from the flux within the solder wire, and there are also quality control disadvantages associated with nitrogen, so we do not make any recommendations regarding its use. Nitrogen is commonly used in the reflow process, and its effects have been confirmed. The reason for its use is to suppress the oxidation of cream solder, but what about its effects in robotic soldering (subsequent processes)? In conclusion, since nitrogen does not have a reducing effect like flux, there is a risk of creating an unbalanced state in the fillet appearance and solder wetting (joint surface). Without relying on nitrogen at an increased cost, pursuing the "appropriate timing" and maximizing the use of the flux (reducing power) within the solder wire can enable high-quality soldering. *For more details, please refer to the PDF document or feel free to contact us.

In the industry, it is commonly understood that methods such as V-slit processing, hole drilling, and preheating for wire solder are effective for reducing solder balls, and these are actively proposed to users. However, in our view, the above measures cannot completely eliminate solder balls and may significantly impair the soldering process itself, so we do not make such proposals. The reasons for the occurrence of solder balls are diverse, and one example of the generation principle is that solder can scatter and form solder balls due to the explosive phenomenon of moisture-absorbing impurities present in the flux components. One of the causes of the flux explosion phenomenon is the rapid temperature rise of wire solder due to the high temperature of the soldering iron tip. Therefore, by using a double motor for the supply of wire solder, we have achieved a stable supply speed, resulting in certain success in preventing the explosion phenomenon. *For more details, please refer to the PDF document or feel free to contact us.*

In industry common sense, it is considered better to increase the amount of solder to secure the back fillet of through holes. However, in our view, the amount of solder is not the issue; rather, it is necessary to create a condition where solder can easily flow into the through holes as a prerequisite. Specifically, it is essential to quickly introduce flux into the through holes before flowing the solder, and if this is not done, no matter how much solder is supplied later, an appropriate back fillet cannot be formed. If the importance of flux is overlooked, one may conclude that "the amount of solder is not adequate (insufficient)." Our robots focus on the "optimal timing" to make the most of the flux, allowing for proper handling of back fillets in through holes without any issues. *For more details, please refer to the PDF materials or feel free to contact us.*

In industry common sense, it is believed that the length of time the tip is in contact (heating time) is proportional to the stability of soldering. However, in our view, the above is an idea caused by "poor timing" in soldering. In other words, as a result of the reduced effectiveness of the flux, the wetting of the solder becomes slower, leading to a negative process where heating must continue during that time. On the other hand, if "good timing" in soldering is achieved, a contrasting positive cycle (balancing tact and quality) will emerge. *For more details, please refer to the PDF document or feel free to contact us.*
