Solder rods are one of the solder products. Solder rods can be divided into lead-free solder rods and lead-free solder rods. Both are used in arc welding. At present, the design of some wave peak furnaces on the market is not ideal. The wave peaks are too high, the peak platforms are too wide, the double-wave peak furnaces are too close to each other, and rotary pumps are used. The peak is too high. When the solder drops from the peak, the temperature drop deviation is relatively large. The solder mixed with air rushes into the tin furnace, causing oxidation and semi-dissolution, resulting in the formation of solder droplet in the solder bar.......

Generally, we all know that there is a lot of residue after welding and it needs to be cleaned. The ones that do not require cleaning are those with less residue after welding and do not need to be cleaned. Not requiring cleaning does not mean there is no residue. Currently, there are two types of solder pastes available on the market: washable solder paste and no-wash solder paste. Many people are asking: Does washable solder paste only need to be washed with pure water? After cleaning, are there any other subsequent treatments? Is it applicable to the soldering operation of circuit boards with high-frequency characteristics? After reflow soldering with no-wash solder paste, is it......

There are many factors that affect wave soldering. When the tin slag content is too high during wave soldering, it is necessary to first determine whether the composition of the tin slag is correct. If the tin slag is in the form of black powder, it is normal. Generally, it will occur in whether the tin slag is normal. Solder bars are one of the solder products. Solder bars can be divided into lead-free solder bars and leaded solder bars. They are both used in arc welding. The following are several reasons summarized by JJY Solder Paste Manufacturer for everyone:1If the peak is too high, the peak is too wide, or the double-peak furnace is too close, choose a rotary pump.2......

What is the soldering temperature for lead-free solder wire? There are commonly two types of soldering we see: lead-free and leaded. The melting point of leaded solder wire is lower180℃Left and rightSAC305It has the best metal content and good welding performance.The melting point of lead-free solder wire is217-228℃BetweenSAC305The metal content is the best, followed bySAC0307Now, JJY solder Paste Manufacturer will share with you two different melting points at different temperatures: the melting point of lead-free solder wire1,S-Cu-NiOf solder wire......

Why do we usually use flux in soldering? Rosin is generally used for small parts soldering, while flux is used for large parts soldering. As we all know, rosin is used for circuit boards and flux is used for single parts soldering. Do you know how to use flux? Everyone should first understand what flux is. Now, let JJY solder Paste Manufacturer explain it to you: Everyone should know that the surface of the copper foil on the copper clad laminate will oxidize, and the solder will also oxidize at high temperatures. If flux is not used......
