Vacuum smelting stir-frying adopts 1GB frequency conversion and power regulation, which can quickly dissolve various metals for 24 hours with full load. The highest temperature can reach 2600 degrees, and the fastest can dissolve a furnace in two minutes. The 38V three-phase GB 5-wire power line is safe and reliable, and the high stable heating system and reliable quality inspection protection function make the whole equipment more durable. Under the protection of vacuum and inert gas, the problems of metal oxidation and irregular corrugations of metal contraction in melted gold or silver are solved.

Tin wire is a kind of alloy solder. High-quality tin wire is the key factor for improving production efficiency. It is also critical when purchasing tin wire. There are several points that must be paid attention to, as follows:

Tin bar is an important soldering auxiliary material in the soldering process of electronic products. According to environmental protection requirements, it can be divided into two types: leaded tin bar and lead-free tin bar. Its main function is to apply to wave soldering or tin furnace circuits. plate welding. Tin bars are also widely used in the electronics industry.

Solder wire is an indispensable material in welding electronic products. Solder wire can be divided into many types, so do you know what are the basis for the classification of solder wire?

Lead-free solder bar adopts high-purity refined tin and advanced smelting process, unique anti-oxidation alloy formula, the amount of slag is very small, the solder joints are bright, reliable, and wettability is good, suitable for lead-free wave soldering and hot dip soldering . However, in the process of soldering, if the lead-free environmentally friendly tin bars are not treated carefully, there will be many abnormal soldering conditions.

Tin wires are divided into lead-free tin wires and leaded tin wires according to environmental protection standards. Leaded tin wires on the market can be divided into different grades, different prices, and different effects according to their tin content. So how do we distinguish tin wires? How about the quality of the line?

Generally speaking, 6337 tin bars are used for spot welding of high-end products such as high-precision instruments, high-end electronics industry, communication industry, WeChat technology, and aviation industry, and Sn50~Sn40 are used for ordinary circuit board welding, such as ordinary household appliances, electrical instruments, automobiles, etc. Parts, general hardware and electrical appliances and other products.

The phenomenon of tin explosion and tin explosion refers to that when the high-temperature soldering iron tip touches the solder wire during the welding operation, it will make a bursting sound, and at the same time, some small tin beads of bright color and solid metal will pop out. This is the fried tin phenomenon.

Everyone knows that it is a kind of solder material that needs to be used in soldering operations. It is mostly used for wave soldering. The storage of lead-free tin bars is mainly for lead-free tin bar manufacturers, and some customers who use lead-free tin bars usually buy The tin bar will be added to the wave soldering at one time for direct production of soldering. So let's understand the storage and storage of lead-free tin bars:

People in the soldering tin industry know that tin wire is not pure tin, but is composed of tin alloy components. Tin alloys mainly include tin-lead alloys, tin-silver-copper alloys, tin-copper alloys, etc. Tin wires are made into hollow wires during the production process, and the interior is rosin , flux, water-soluble resin, activator, etc., and then pulled into a filament and evenly wound on the reel, the following solder paste manufacturers will explain:
