Production technology and application of solder wire

Update time : 2023-05-11 15:08:51

Introduction:

As an important welding material, solder wire is widely used in the electronics industry to connect and repair various electronic components. The production process of solder wire is related to its quality and performance. This paper will introduce the preparation method and process flow of solder wire and its application in the electronic industry.

One, Preparation method of solder wire:

Solder wire is usually prepared by the following steps:

Preparation of raw materials: Select high purity tin and other alloy materials as raw materials. The purity of tin has an important effect on the quality of welding, therefore, high quality solder wire requires high purity of raw materials.

Material melting: The choose raw material is put into a furnace for melting. The raw materials are completely melted and mixed evenly by controlling the temperature and time in the furnace.

Casting molding: Molten alloy is poured into the mold, through casting molding, to prepare the desired diameter of the solder rod.

Saw into wire: Saw the solder rod to the required length, and through the drawing machine to pull the solder rod into the desired diameter of the solder wire.

Two, solder wire process:

The production process of solder wire includes the following main technological processes:

Screening of raw materials: strictly screening of raw materials to ensure their purity and quality meet the requirements.

Material melting: The sifted raw material is put into a furnace, and the temperature and time are controlled to make it completely melt.

Casting molding: The molten alloy is poured into the mold, which is cooled and solidified to form a solder rod.

Sawing and drawing: Sawing the solder rod to the required length and drawing it through the drawing machine into the desired diameter of the solder wire.

Cleaning treatment: cleaning treatment of solder wire, remove surface pollutants, improve welding quality.

Packaging and quality inspection: butt welding.
