Use a constant temperature soldering iron when soldering.
1. There are two types of
lead-free tin wire containing silver: 0.3 silver lead-free tin wire and 3 silver lead-free tin wire. The melting point of silver-containing lead-free tin wire is 217 degrees, and the soldering temperature is almost 260 degrees.
2. There are few customers for solid core lead-free tin wire, which is mainly used for the welding of special products. The melting point of solid core lead-free tin wire is 220 degrees, and the welding temperature is adjusted to 260-270 degrees for comparison.
3. The melting point of tin-copper lead-free tin wire is 227 degrees, and the temperature of the electric soldering iron is set at 280-300 degrees when performing manual soldering, which is relatively suitable.
Nickel-plated lead-free tin wire is mainly involved in a nickel-plated component in tin-copper lead-free tin wire. It is suitable for the welding of nickel-plated plates and nickel-plated components. The welding temperature is the same as that of tin-copper lead-free tin wire. is 280-300 degrees. The welding of lead-free and environmentally friendly tin wire is basically a manual electric iron. There are many types of electric soldering irons. The welding of lead-free tin wire adopts a constant temperature soldering iron. The result is relatively ideal.
What is the tin bar mainly used for? Solder can be used for hermetic metal welding under conditions that do not require high temperature and high pressure. Tin bar is a solder bar used for soldering, which is used in the soldering of circuit boards.
Solder bar is an important industrial raw material for connecting electronic components in welding lines, and is widely used in the electronics industry, home appliance manufacturing, automobile manufacturing, maintenance industry and daily life. Solders with a lower melting point mainly refer to solders made of tin-based alloys.
Leaded solder bar is an alloy composed of tin melting point 232 degrees and lead 327 degrees. Recycled tin bar The solder composed of 63% tin and 37% lead is called eutectic solder. The melting point of this solder bar is 183 degrees. It is also called leaded solder bar in our industry, and there are also lead-free solder bars. , its main components are tin, silver, and copper. The commonly used ones are Sn99.3Cu0.7 and its melting point is 227 degrees. It is used in wave soldering. Its pertinence should be precise and the requirements are also higher.
