During the welding process of the tin bar, some unexpected situations will occur, resulting in poor welding. What is the reason for the tin bar to appear in these situations?
1. The flux and the bottom surface are in poor contact; the angle between the bottom plate and the liquid surface is improper.

Lead-free tin wire is an alloy composed primarily of tin, but also contains other metals. It is mainly divided into lead 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. At present, the main products on the market are lead-free solder paste, lead-free solder bars, and lead-free solder wires. Leaded solder is mainly composed of tin and lead in various proportions; lead-free solder is composed of tin-copper, tin-silver-copper, etc. Since the composition of the alloy and the proportion of each composition are different, the melting point of different solders is also different.

Solder wire is a very important material in the electronic soldering industry, used for manual soldering of products and automatic soldering with the aid of machines. The tin wire is composed of two parts: tin alloy and flux. The alloy components are divided into tin-lead, tin-copper, etc., and the flux is evenly poured into the middle part of the tin alloy. The common classifications of tin wire are lead-free tin wire and leaded tin wire (also called lead-free solder wire and leaded tin wire); tin wires with different compositions have different melting points and corresponding uses.

When the solder wire is welded, the tin wire is filled with rosin. When the temperature of the soldering iron is high, the molten solder wraps the rosin, and the rosin inside is rapidly vaporized at high temperature, and the wrapped solder is washed away, resulting in a popping sound. At the same time, some brightly colored small tin bead solid metal will pop up, which is the phenomenon of fried tin.

There are various reasons for the short circuit between the solder joints of the circuit board formed during the soldering process with solder paste, which can be mainly divided into three categories: one is the reason of the solder paste itself; the other is the reason of the incoming circuit board ; The third is the influence of welding process. Solder paste manufacturers can analyze the reasons for these defects one by one:

1. the use of solder paste is different
        The biggest feature of no-clean solder paste is that it can be free from cleaning. After the circuit board is soldered with no-clean solder paste, it can proceed to the next step of testing and assembly without cleaning. After SMT manufacturers use solder paste for soldering, the surface of the circuit board is relatively clean, and the volatilized residue after the solder paste is melted is relatively small. The circuit board can pass the inspection of various electrical

With the increasing awareness of environmental protection, the solder in the electronic manufacturing industry is also required to be environmentally friendly. Therefore, environmentally friendly tin bars have begun to replace traditional leaded tin bars. The price of environmentally friendly tin bars is higher. From the perspective of cost saving, waste environmentally friendly tin bars need to be recycled.

Tin/Lead-based solder is the most commonly used solder in electronics assembly, but in the last year there has been a push across the industry to switch to lead-free solder bar. The rationale is that there is a growing understanding of lead use and its adverse effects on human health.
Health hazards associated with lead include neurological and reproductive disorders, and neurological and physical developmental delays. Lead poisoning is particularly harmful to the neurodevelopment of young children.

1 Definition of solder: the use of heating tools (electric ferrochrome) to firmly join two or more point metal conductors to achieve the purpose of conducting electricity.
make process.
2 Common sense of solder: There are generally two types of solder commonly used in toy assembly:
A. Tin bar: It is used on the wave crest passing tin machine specially used for electronic pulling, which will not be introduced here.
B. Tin wire:
a Composition: 60% tin, 40% lead, the hollow part of the tin wire contains flux.
b. Features: The melting temperature of the tin wire is above 190 C, and the conductivity is good.

Surfactants are very common in our production and life, such as our common styrofoam, the foam used for shaving, and also in detergents. It is added in the industry, and it also exists in personal care products. Of course, this substance is also necessary in lead-free solder paste. Because the surface tension of the metal to be soldered needs to be improved, the solder paste manufacturer adds a small amount of active agent. It can make the product have good moisturizing performance and speed up the welding process. Surfactants are composed of two ions with completely opposite physical properties.
