The main problems in the production process are as follows

1. Yellow solder joints appear after tinning on the tin wire: this phenomenon is caused by excessive soldering temperature, you should immediately check the temperature of the tin furnace or the temperature of the soldering iron tip and whether the thermostat is faulty;

Solder wire is an indispensable material in welding electronic products. Solder wire can be divided into many types, so do you know what are the basis for the classification of solder wire?

Tin bar is an important soldering auxiliary material in the soldering process of electronic products. According to environmental protection requirements, it can be divided into two types: leaded tin bar and lead-free tin bar. Its main function is to apply to wave soldering or tin furnace circuits. plate welding. Tin bars are also widely used in the electronics industry. So what are the important ingredients in tin bars? The following editor will explain to you:

With the continuous improvement of technology, tin wire has also made great progress. According to the different metal components, tin wire can now be divided into lead-free environmental tin and lead solder. Among them, lead-free environmentally friendly tin wires are relatively widely used, and lead-free tin environmental protection wires are environmentally friendly products. Due to the high cost, attention should be paid to reducing waste in production.

The so-called tin dragging is a kind of solder wire welding process. Its purpose is to ensure the reliability of welding and prevent false welding. Operators engaged in solder wire welding operations must be very familiar with it. Let's talk about the tin dragging skills and precautions when soldering with solder wire:

Tin wire is used for soldering electronic components. Today we mainly sort out the problems of how to manage and store the purchased tin wire for you: First of all, the purchase of tin wire is generally purchased by the factory in a unified manner. The purchaser must understand the specific material requirements and welding performance and purchase the corresponding tin wire according to the actual welding needs.

No-clean solder wire is divided into halogen-containing type and halogen-free type according to whether the solid flux used contains halogen. The halogen-containing type is represented by ML, and the halogen-free type is represented by M. An example of the grade of halogen-containing no-clean solder wire is expressed as: MLSn60 An example of the grade of halogen-free no-clean solder wire is expressed as: MSn60.

Generally, tin wires of various specifications will be encountered in some electronic industries. Now that it is more and more developed, auxiliary materials for tin wires are also indispensable. Nowadays, electronic solder is the product with the largest consumption, so we generally use it in the production process.

Tin wire manual soldering requirements for solder joints: ①The connection performance of tin wire is good; ②The tin wire has a certain mechanical strength; ③Smooth and rounded tin wire solder joints.
