How should electric ferrochrome be used in tin wire welding?
Sep 27, 2022
09-27
2022
The electric soldering iron is used for soldering, and it is one of the indispensable tools for manual soldering; The best composition of its solder wire is composed of 60% tin and 40% lead.
Before using the new electric soldering iron, use a file to file the tip of the soldering iron. After the power is turned on, the color of the soldering iron tip will change for a while, which proves that the soldering iron is hot. Then use the solder wire to put tin on the tip of the soldering iron to make the soldering iron Not easy to be oxidized. During use, the tip of the soldering iron should be kept clean and there should always be solder on the tip of the soldering iron.
Lead-free environmentally friendly tin bars play an important role in work
Sep 26, 2022

2022
Lead-free environmentally friendly tin bars play a very important role in welding work. Tin bars made of different alloy compositions also have different properties and uses. When using lead-free environmentally friendly tin bars, you need to pay attention to the following aspects:
(1) Pay attention to the height of the liquid level in
Causes of solder slag from lead-free environmentally friendly tin bars
Sep 26, 2022
09-26
2022
Lead-free environmentally friendly tin bars will also produce solder slag during the welding process, which is a normal oxidation phenomenon. The lead-free environmentally friendly tin bar is made of pure tin and trace copper. Antioxidants are added to it. Compared with traditional tin bars, it has high wettability, good fluidity, and is easier to tin. At the same time, the solder joints are bright and full, and there will be no false soldering. It has become the main choice for wave soldering today. So what causes solder slag?
Mechanical properties of lead-free solder wire
Sep 23, 2022
09-23
2022
The reliability of lead-free solder wire depends not only on intrinsic characteristics, but also on the design and components and boards to be mounted, the process used to form the solder joints, and the long-term use environment. Also, the properties of the solder joints are different from those of the bulk lead-free solder wire.
What are the characteristics of lead-free solder wire?
Sep 23, 2022
09-23
2022
Lead content has always been a controlled part of solder wire, and the ultimate goal of industry efforts is to minimize lead content. The emergence of lead-free tin wire has solved a major problem for people in the industry, won the recognition of the world, and has become an important part of China's export products, especially exported to European and American countries. The reason why lead-free solder wire has won so much applause is because it has the following characteristics compared with lead-free solder wire;
Considerations when choosing flux cored tin wire
Sep 22, 2022

2022
The preparation of flux-cored tin wire is relatively complicated, and the process control is strict, including: smelting, casting, extrusion, rough drawing, fine drawing and wire winding and other processes. How to ensure the uniformity of the flux in the tin wire and avoid broken rosin defects is the whole The most critical process in the tin wire process.
Consider the following factors when selecting flux cored wire:
Soldering standard for flux cored tin wire
Sep 22, 2022

2022
Flux cored tin wire test welding, the solder joint should be smooth and shiny. No false welding, virtual welding phenomenon. Adjust the tin furnace temperature to 270±10℃, when the specified temperature is reached, the tin bar should melt. The molten soup should be shiny and free of impurities. Hold the tin wire in one hand and the soldering iron in the other hand, and put the soldering iron on the pins. When the pins are hot, put the solder wire on the joint of the soldering iron and the pins. When the amount of tin is almost the same, remove the soldering iron and the tin wire at the same time. . But this way I often get the pins very hot, and the tin is not enough, and the tin sometimes hangs on the soldering iron and doesn't flow down.
Purpose of Soldering with Solder Paste

1. Characteristics of soldering with lead-free solder paste
Soldering with solder paste manufacturers can perform mechanized operations and complete a large number of soldering operations in a short period of time. For example, our common use of SMT process, wave soldering process and hand dip soldering process all use solder for soldering. The difference between several soldering processes is the use of different soldering materials. For example, the common SMT process uses solder paste for soldering, and the wave soldering and hand dip soldering processes use solder bars for soldering.
Welding requirements and characteristics of active lead-free solder wire
Sep 21, 2022
09-21
2022
Soldering requirements for active lead-free solder wire:
Active lead-free solder wire generally has better welding effect with a constant temperature soldering iron, and the welding speed is relatively fast. Novices who use solder wire need to be trained for a period of time. If a variable temperature soldering iron is used, the tip of the soldering iron should be adjusted to the optimum soldering temperature on the solder wire manual. If there is a quality problem, please connect the business department as soon as possible, and the business department will send warehouse related personnel to handle the exchange.
The understanding and purchase of tin wire
Sep 20, 2022

2022
Tin wire is the most common welding material used in the welding of electronic and electrical products. Tin wire is mainly an industrial soldering solder used for connecting electronic devices to circuit boards.
Improper operation will cause the wire to be discarded, and the discarded tin wire can be reused by recycling to improve the utilization rate of the tin wire.
