Solder wire is common in electronic assembly work, lead soldering. The purpose is to connect short circuits together to create a detailed closed circuit. Whether the quality of the circuit is good at conducting current or not, and whether it can be common for a long time does not depend much on the state of use of the solder wire. There are many lead-free solder manufacturers 2021.
What is solder wire?
Tin solder wire is another low melting point alloy that only needs to be between 90 and 45xUdHPiFHQ7xbKh19G45saF1raB2ot5pag8p1Hnk4yrfXRJZskr8TMbFpVfC5tDk8eQQg63TqkW9gKhwagx6HePTaK2yXb soldering electronics, depending on the different purposes of use, the composition of the solder wire is different, but still retains the characteristics of the solder metal, which is capable of conducting.
Solder wire products
There are two types of solder wire, lead-free and lead-containing manufactured by lead-free solder manufacturer 2021. In the current Vietnamese market, we can only produce lead-containing solder wire, and most other products have to be imported from overseas China, Korea and Japan.
The components of solder wire are commercially available
The purpose of using solder wire is to reconnect two metal parts together and the first thing needed is the solder joint. The composition of solder wire is an alloy of lead and tin. Common solder wire is an alloy consisting of 63 % tin and 27 % lead, called Eutectic alloy, which has a melting point of 183 degrees Celsius and is most commonly common today.
Lead-free solder manufacturer 2021 says that lead solder wire consists of 100% tin, melting temperature from 340 to 370 degrees Celsius. Solder wire and alloy with 96.5% tin, 3% silver and 0.5% copper at a melting point of 217 degrees Celsius. In solder joints, lead always takes up the majority and takes a long time to harden after soldering is over, so you can wipe them off easily.
Is solder wire toxic?
Lead in solder wire, or lead materials in general, are very harmful to human health, even in small amounts, so solder lead is harmful to users, very thin, so it can be common. According to lead-free solder manufacturer 2021 lead affects many organs and tissues around the heart, bones and intestines, is toxic to the reproductive and nervous systems, causing many symptoms that affect
learning and behavior.
Symptoms include headache, anemia, discomfort in the body; severe symptoms will cause a coma that can be fatal, extremely dangerous. Therefore, we must not use lead solder in water pipes, mainly common in the electrical industry; welders need to take protective measures to avoid harm to the body.
Solder wire is often replaced with copper or antimony with the addition of silver.
Producing tin wire soldering thread
In an operation line, we need 6 main types of machines:
Furnace: to melt raw tin, for production
Extruder: can extrude different types of solder wire, tubular tin wire
Laminating machine 1: common to roll a large tin wire into smaller ones
Roller 2: continue to small roll the product formed from the 1 cán rolling mill
Roller 3: continue rolling until the tin wire diameter is from 1.8 mm to 0.6 mm or less.
Winding machine on coil
Lead free wire manufacturing process by lead-free solder manufacturer 2021
Lead-free solder manufacturer 2021 includes bar solder wire and wire solder wire.
1. Step of pressing, cutting and pulling, rolling
Use support tools such as presses, tractors, and Stanley pliers. Purpose:
The specified temperature must be maintained
Add more gasoline and IPA to the tractor
In addition, Monitor the filling of oil and water into operating machines
2. Inspection step before packing
Check size, weight
Similarly, Check the amount of Flux in the solder
Moreover, Handling unsatisfactory shipments
Using measuring equipment, scales, hand soldering machine to check the quality of solder tin, observing mainly by eye.
3. Delivery step
Provide how to produce solder wire manufactured by lead-free solder manufacturer 2021
Provides more lead-free solder for a brighter solder spot
The effect of the flux is to make the welds more shiny and beautiful, and the detergents also help to bring a high soldering effect.
What the types are of solder wire?
Solder wire is divided into 3 main types and depending on the preferences and purposes of using solder wire. We can use it under different conditions. So how to use and how does the composition of solder lead work, let's find out. The ratio of 63 tin and 37 tin lead optimizes soldering for a glossy, fusible solder suitable for use in soldering electronic circuits said by lead-free solder
It is also the lowest melting point Eutectic alloy, with many other special features. Another type is 60 tin and 40 lead which has a high melting point, is liquid and gives a less glossy solder joint. 63/37 solder wire is better than 60/40 because it cures faster and reduces the risk of damaging the weld. Standard welders will often come with a layer of sealant that protects the weld from oxidizing.
Solder flux in solder wire
Some standard solder wires include single-core or multi-core Flux Liquid flux, solder fluxes with acid composition to help clean the weld, can be turpentine or cleaning solvents. According to lead-free solder manufacturer 2021 wire must be common without lead. Solder cleans the weld and reduces surface tension thus resulting in smoother welds.
You can make your own flux by crushing turpentine and then adding acetone or gasoline and stirring until the turpentine dissolves into a dark yellow iridescent color. To avoid evaporation, you use as much as you can, to avoid creating waste. This homemade solution can be applied to the solder preparation site, printed circuitry, preventing oxidation, and making soldering easier.
95/3/0.5 respectively 95% tin, 3% silver, 0.5% copper are especially good, so the price is also especially high. Also known as silver solder, depending on the conditions of use, the lead-free solder manufacturer 2021 can adjust the amount of silver and copper and reduce the required part. It is possible that grade 62/36/2 is more common when welding metals, creating a strong weld, electrical and thermal conductivity is also good.
Melting temperature when soldering
The melting temperature of the solder wire is from 200 to 280 degrees, so when using the soldering machine, the temperature should not be too high, causing the circuit board to burst, causing the circuit to burn, causing the tin wire to melt and crumble.
