Description

Tin coating equipment for electronic product production and processing

Technical Field

The invention relates to the technical field of electronic product processing, in particular to a tinning device for electronic product production and processing.

Background

The electronic products are related products based on electric energy, and are named as electronic products because early products mainly use electronic tubes as basic elements, and the electronic products generally need to be subjected to tinning treatment in the production process, so that a tinning device or a soldering device for producing the electronic products appears. Solder is an important industrial raw material for connecting electronic components in a soldering circuit, is a solder with a low melting point, and mainly refers to a solder made of tin-based alloy. The solder is produced by a melting method to produce an ingot and then press-processing the ingot into a material. Solder materials are essential in production and maintenance work in the electronic industry, and generally speaking, common solder materials include tin-lead alloy solder, antimony-added solder, cadmium-added solder, silver-added solder and copper-added solder. The wire solder used in standard soldering operations is called a rosin-cored solder wire or solder wire. Flux is added to the solder. The soldering flux consists of rosin and a small amount of active agent. The setting of the temperature during the welding operation is very important. The most suitable temperature for the welding operation is the melting point of the weld used +50 degrees. The set temperature of the soldering iron head is preferably increased by 100 degrees on the basis of the temperature due to the difference of the size of the soldering part, the power and performance of the soldering iron and the type and line type of soldering tin. The main products of soldering tin are classified into three major types of soldering tin wires, soldering tin bars and soldering tin pastes. The solder paste is applied to various electronic welding, and is suitable for processes such as manual welding, wave soldering, reflow soldering and the like.

However, the existing soldering tin device for producing electronic products still has defects when in use, most of the existing soldering tin devices are simple in structure, the soldering tin feeding operation is only a straight line, in the actual production process, the soldering tin path is required to be an irregular circuit, and the existing soldering tin device cannot meet the conditions when the existing soldering tin device is used for processing the products; in addition, a large amount of smoke is easily generated in the tin soldering process, and the workshop environment is influenced; secondly, the fumes contain acidic components, which can cause corrosion, damage and other negative effects on the machine parts that have been smoked. The existing common technology is that the air draft cover is installed right above the machine, thus the machine part can not be protected, and meanwhile, the air draft effect is limited and the electric energy is wasted due to the fact that the air draft opening needs to be opened greatly (larger than the area of the table top of the machine).
