Is solder paste toxic? What protective measures are needed? JJY Solder Paste Factory would like to share with you:Sep 06,2021

Is solder paste toxic? What protective measures are needed? JJY Solder Paste Factory would like to inform everyone: Nowadays, there are two types of solder pastes, one is lead-free solder. Whether it is leaded solder or lead-free solder, both are toxic. The alloy of tin and lead is the commonly used solder for crossing canals. It has the good electrical conductivity of metals and a low melting point, so it has long been used in the welding process. Its toxicity mainly comes from lead. The lead fumes produced by soldering are easy to conduct......

JJY Solder Paste Manufacturer teaches you the skills and methods of operating solderingSep 06,2021

Generally, when soldering is heated, it is harmful to our health. If the nose is too close to the tip of the soldering iron during operation, it is very easy to inhale harmful gases. Generally, the distance between the soldering iron and the nose should be at least no less than30cmUsually, it is generally40cmIt's better. So manual soldering is the normal step. JJY Solder Paste Factory mainly deals in lead-free solder wire, solder wire, environmentally friendly solder wire, leaded solder wire, lead-free solder bar, leaded solder bar, lead-free solder paste, leaded solder paste......

Improvements, issues and highlights of lead-free solder paste in SMT processesSep 06,2021

SMTThe use of lead-free solder paste in the process for improvement, problems and highlights. Generally speaking, solder joints with lead-free solder paste are brighter,Because it contains lead components.Lead-free solder paste solder joints are darker,Because there is no lead component in it.Solder joints are not necessarily better the brighter they are,The weld points are required to be smooth and glossy.PCBASpecial cleaning agents should be used when cleaning,Remember not to clean with alcohol. The most important factor is that when soldering solder paste with the same composition, the soldering temperature, that is, the reflow soldering temperature, must be adjusted. These points are crucial......

JJY solder Paste Manufacturer shares: The usage method of lead-free low-temperature solder pasteSep 04,2021

JJY solder Paste Manufacturer shares: The usage method of lead-free low-temperature solder paste. Generally speaking, the basic principle of using and storing lead-free solder paste is to minimize its contact with air to avoid oxidation. If lead-free solder paste is exposed to air for a long time, it will cause oxidation of the solder paste and corresponding changes in the proportion of flux components. The result will be: the solder paste will have hard skin, hard lumps, be difficult to melt, etc., and a large number of solder balls will be produced during the production process.1:Heating stage:In the heating zone......
