What effects will there be if the warming time of solder paste is insufficient?May 18,2023

Solder paste is a commonly used soldering material in the production of electronic components, and some details need to be noted when using it. One of them is the warming time. The warm-up time refers to the time required to heat the solder paste from a low-temperature state to the normal operating temperature. If the tempering time is insufficient, it will have a certain impact on the welding process. Firstly, insufficient warming time will lead to a deterioration in the fluidity of the solder paste. At normal operating temperatures, the fluidity of solder paste is of great significance as it directly affects the soldering......

How to deal with the residual flux in reflow soldering?May 17,2023

Reflow soldering technology is not unfamiliar in the field of electronic manufacturing. The components on various boards used in electronic devices are all soldered onto the circuit board through the reflow soldering process. Inside the reflow soldering machine, there is a heating circuit that heats air or nitrogen to a sufficiently high temperature and then blows it towards the circuit board where the components have been attached, causing the solder on both sides of the components to melt and bond with the main board. Flux paste is a product used in reflow soldering during operation, and its function is to help reflow soldering reach its maximum range......

Its main components are flux and some metal alloys, such as lead, tin, silver, copper, etc. Then many people have doubts?Are there any harms to people's bodies from these things?To address everyone's doubts, next, JJY Solder Paste Manufacturer will explain to you whether solder paste is harmful to the human body?Solder paste can be generally divided into two types: leaded solder paste and lead-free solder paste. Leaded solder paste is a mixture of soldering flux components and alloy components......

Is solder paste needed when soldering?May 15,2023

Soldering is a welding technology widely used in fields such as electronic devices, manufacturing, and the automotive industry. When performing soldering, it is usually necessary to operate in conjunction with solder paste to ensure the stability and quality of the soldering. Solder paste is a paste containing binders and fusible substances, which can enhance the contact and wettability of solder joints and ensure the reliability of soldering. However, in some cases, solder paste is not necessary. First of all, if the surface of the welded parts has already undergone special treatment......
