Nowadays, with the development of The Times, there are more and more electronic industries. Everyone knows that the current electronic products are very thin both in appearance and interior, and this inevitably requires the assistance of solder wire as solder.Low-temperature tin wireIt curls up just like the iron wire in daily life, so everyone still needs to have some understanding of the product. Now, the solder paste manufacturer will briefly discuss the production process and introduction:

The first step: Prepare raw materials, mix ingredients, and prepare tin and lead/The testing of copper, rosin and anti-oxidants (detailed requirements can be found in the proportion range with national standard codes) can only be carried out after the inspection staff check that the materials meet the standards.

The second step: Melting of tin material. After adjusting the main and auxiliary materials in a certain proportion, they are put into the furnace for melting. After melting, an anti-oxidant is added to cover its surface. This is to prevent tin dioxide (chemical formula) in the tin materialSnO2It is white and square in shape. Stir it slightly at a higher temperature until it is completely dissolved.

The third step: For the tin casting billet, the heating oil during the melting process is mainly electric heating. Some manufacturers also use coal heating. With oil and electric heating, there are specially designed heating furnaces that can actively stir and control the temperature in real time, eliminating poor melting caused by human factors. The melted tin is poured into the mold and cast into a rod-shaped billet.

The fourth production step: In the entire production process of solder wire, the extrusion of solder material is the most crucial. As extrusion is the most crucial part of the key in the entire production process, if there are defects or hidden dangers during extrusion, it will lead to irreparable defects in the solder wire. It is difficult to detect problems occasionally. To ensure the production of high-quality solder wire, precise control of extrusion is necessary. Solder wire is extruded from a very heavy rod-shaped object in a hydraulic press and extrusion die. During the extrusion process, attention should be paid to wire breakage. According to production requirements, round wire, flat wire and thick wire can be produced. The thickness can be determined using another die.

The fifth production step: Winding. During operation, when the winding is smooth, the number of turns can be counted under fully automatic control. During winding, problems such as uneven and misaligned winding may occur. These issues need to be meticulously addressed during production.

The sixth step: Inspection, packaging and inspection of solder wire into the finished product warehouse.

Suppliers of electronic auxiliary materials such as solder wires, solder bars and solder pastesSZL/Double Chile mainly deals in solder wire, environmentally friendly tin wire, leaded tin wire, lead-free tin bars, lead-free solder paste (high temperature, medium temperature, low temperature).LEDSolder pasteQFNLead-based solder paste, special solder paste for stainless steel, and environmentally friendly products all meet the performance requirementsROHSStandards and through third partiesSGSCertification, suitable for various requirements of electronic products, printing production, etc.

Now, after the above introduction, everyone should have a relatively clear understanding of this product. Therefore, when using this product, you should also pay attention to the surrounding conditions. Ventilation is very important.
