China's industrial revolution started later than western countries a century. In the process of reform and opening up, the development of industry and catching up with the western science and technology industry, the problem of environmental pollution is ignored for the sake of economic benefits. In the modern era of rapid development of industrial technology, most countries began to realize the importance of environmental protection, especially the introduction of ISO14000, and began to prohibit the use of lead materials in welding tools and welding materials. In our traditional thought, also reflect on whether we can give children a piece of pure land. Today, environmental protection has become a worldwide topic.

In the early 90s, manufacturers of electrical equipment did not have much choice for welding tools and materials because of the limitations of market supply and cost. Most can only use the traditional electric iron, but this can not meet the production efficiency of the factory, also does not meet the requirements of environmental protection. Lead pollution, temperature slow, temperature instability and other factors of popular criticism. Tool manufacturers continue to upgrade product launch, thermostatic soldering station, lead-free soldering station, high-power welding station. Next we discuss the lead-free welding on welding tool and welding material requirements.

Brief introduction: PCB plug-in board manual welding, usually choose constant temperature soldering station welding, a new generation of constant temperature soldering station is based on voltage control transformer, to achieve the temperature control of the heating element, heat type is more stable. The temperature is 200-480 degrees and the power consumption is between 60W-75W. Lead free soldering head. According to the size and melting point of solder wire, it can be adjusted and suitable for temperature, and provides convenient and quick operation mode for welding workers. Greatly improve the welding efficiency and environmental protection conditions.

PCB double-sided board component SMT lead-free soldering: usually use lead-free soldering platform for welding, lead-free soldering platform on the basis of the original improvement and practical function improvement. From the design and selection of materials to take into account the electrostatic damage to the components, so as to add anti-static function. Increase power from 75W to 100W, so as to achieve lead-free soldering at low temperature. Equipped with automatic sleep, save power, digital display temperature and correction function. The emergence of a new generation of intelligent welding platform, to meet the needs of the electronic factory.

Large solder joint high power lead-free welding: with the increase of industrial products, the integrated circuit processing technology is different, the smaller power soldering station still can not meet the requirements of production. Therefore, the high-power welding platform produced, the new generation of high-power welding platform using electromagnetic high frequency eddy heating principle, from the machine to the heating elements of the structure of revolutionary improvement. Such as power increased from 90W to 150W or even higher, adjust the temperature of 50-600 degrees. The moment back to temperature, temperature compensation speed can solve the lead-free welding to produce temperature not to weld, sealing off problems, but also solve a series of problems of low temperature welding specific conditions, perfect.

The majority of manufacturing enterprises in the selection of welding tools and solder process, can consider environmental issues, select the appropriate products of their own tools, for China's environmental protection cause, everyone a share of the force!
