What temperature should be set for lead-free tin strips during use?

Generally speaking, during the usage process, we should set the appropriate temperature. I believe many technical experts have discussed this issue. The general temperature setting for lead-free solder strip soldering is280Positive or negative10The temperature setting is generally high because manual dip welding does not involve preheating,The main components of commonly used eco-friendly tin strips are99.3%Tin0.7%Composed of copper, solid, silvery white and odorless, with a melting point of227℃ The working temperature is270℃-300℃The weld points are relatively bright and are used for welding with higher requirements. They are widely applied in wave furnaces and hand immersion furnaces. Environmental-friendly tin strip temperature (peak temperature)270~300℃The specific lead-containing solder rods depend on the lead content and the material of the components to be soldered. Now, let's talk about it from JJY solder Paste Manufacturer:

High-temperature tin strip :
　　The liquidus temperature is higher than the melting point of the tin-lead eutectic. 183 ℃ And it can exceed 450 ℃ A tin bar that can maintain its working temperature without oxidation and can be welded normally is called a high-temperature tin bar. High-temperature tin bars are made by adding specially formulated additives to tin-lead alloys, which exceed 450 ℃ The above can also play an oxidizing role. The product is suitable for welding processes with high working temperature requirements. For example: tin on the lead pins of a transformer, etc. Our factory is equipped with various alloy ratios for customers to choose from. 

Low-temperature tin bar
　　Melting point lower than183℃The solder can provide different soldering processes and solder alloys with different melting points. 

High oxidation resistance solder bar
　　in300℃At the following welding temperatures, the surface of the liquid energy solder is like a mirror, the wetting time is short, and the expansion rate is greater than that of ordinary solder. The addition of anti-oxidation makes the weld points bright, lustrous and beautiful, suitable forPCBWave soldering and hot-dip soldering. Our factory is equipped with various alloy ratios for customers to choose from. 
Anti-oxidation high-temperature solder rods
　　in450℃Under high-temperature conditions, the surface of the solder can maintain a silver-white mirror-like state for a long time, and the slag output is only that of ordinary solder 1/7It is suitable for wave soldering and hot-dip soldering processes, and is particularly suitable for tinning self-dissolving enameled wires during the manufacturing of various transformers. The effect of low slag content not only reduces defective solder joints and saves cost expenditures, but also decreases the maintenance opportunities for soldering.

The above is an introduction to the unnecessary ones for everyoneLead-free tin barIf you still want to know more about various temperature conditions, you can discuss them together.
