Tin wire structure
Dec 29, 2022

2022
The skill of tin wire welding is a proficient process. The speed of soldering mainly depends on the selection of solder wire. The speed of tinning on high-quality solder wire is fast. For the ordinary soldering structure of PCB, it is usually required that the size of the solder joint between the solder wire and the PCB should be Select the solder wire with high tensile strength and high activity for the alloy structure of the solder joints of the PCB board.
How to achieve high-quality results in lead-free solder paste

Along with the generation of SMT, lead-free solder paste also came into being. It combines flux and solder powder, as well as thixotropic agent and surfactant, so as to achieve better soldering effect during the soldering process. Lead-free solder paste is usually used in the soldering process of capacitors, resistors and other components on the surface of PCB.
Special wave soldering maintenance for lead-free tin bars

The mechanical part of the wave soldering furnace dedicated to lead-free tin strips: If the machine is running for too long without maintenance, the spot inspection will show that the screws are loose, the density of the gear teeth is not good, the chain speed slows down, and the transmission shaft may be rusted Deformation of the track (such as bell mouth, trapezoidal shape, etc.)
Judging the sensitivity of environmental protection tin wire

The sensitivity of the environmentally friendly tin wire indicates the ability of the environmentally friendly tin wire to receive weak electromagnetic wave signals. The sensitivity of the environmentally friendly tin wire mainly depends on the performance design of the circuit in the image channel part of the environmentally friendly tin wire.
Selection of soldering working conditions for lead-free solder bars

2022
Where there is no DC welding machine, lead-free tin bars for both AC and DC should be used. Metal elements are precipitated to form lead-free tin bars. The increase of other metal content and impurities will affect the welding effect of the lead-free solder bar and the oxidation speed of the lead-free solder bar is too fast, resulting in an increase in tin slag.

Reflow soldering of solder paste is the main board-level interconnection method used in the SMT assembly process. This soldering method combines the required soldering characteristics excellently. These characteristics include ease of processing, wide range of SMT designs Compatibility, high soldering reliability, and low cost; however, when reflow soldering is used as the most important SMT component-level and board-level interconnection method, it is also challenged to further improve soldering performance.
Method for identifying the quality of solder bars

1) The merchant can be required to present the qualification inspection report related to the provision of solder bars. To analyze the various data of the solder bar, so as to understand the accurate information of the solder bar, and reasonably set the method of use.
The characteristics of lead-free solder bar and its soldering temperature are intuitive

For lead-free welding of products exported to Europe, America and other countries, the tools and components used must be lead-free. Lead-free solder bars have light yellow traces, because lead-free generally contains copper metal. Lead-free solder bars are basically lead-free (the EU ROHS standard is less than 1000PPM, and the Japanese standard is less than 500PPM). Lead-free solder bars generally contain tin, silver or copper metal elements.
How to Avoid Machine Dip Soldering of Lead-Free Solder Bars

Solder bar is an essential solder material for immersion soldering. It can be divided into leaded solder bar and leaded tin bar. Leaded tin bar is mostly used for non-exported electronic products. The lead-free solder bar produced by Yizheng Xujiazhuang Industry and Trade Co., Ltd. is made of raw tin. Good wettability and fluidity, easy to tin; Solder joints are bright and full, and will not have bad phenomena such as false soldering.
How to prevent the smoke generated by lead-free tin wire during soldering

2022
Lead-free tin wire is an alloy consisting primarily of tin, but also containing other metals. Mainly divided into leaded and lead-free, everyone knows that lead is a toxic metal, so lead-free is more environmentally friendly. Now more and more factories choose lead-free and environmentally friendly, and lead-tin wires are gradually being replaced. The main products currently on the market are lead-free solder paste, lead-free solder bars, and lead-free solder wires.
