Choosing JJY solder paste means choosing quality and using it with peace of mind

SMTOne of the essential production materials in electronic assembly isSolder paste. Choose good solder paste for itSMTSoldering is a very important matter. There are numerous solder paste manufacturers, and the price of solder paste is not cheap either. This requires us to be vigilant when making a choice.

Why choose JJY solder paste

Firstly, JJY solder paste has good rolling and tin dropping properties during printing, and is suitable for low temperatures0.3㎜The pads with spacing can also achieve exquisite printing. During continuous printing, the viscosity changes very little, and the operational life of the steel mesh is long, exceeding12It will not dry out even after hours and still maintain a good printing effect. It remains in its original shape for several hours after printing, with basically no collapse and the surface mount components will not shift. It has good resistance to cold and heat collapse. Because the viscosity is higher than that of the ordinarySMTThe solder paste is low. Lead-free solder paste is relatively more prone to collapse, while lead-free no-wash solder paste has a greater surface tension than traditional solder paste during melting. Therefore, if it collapses and connects to other pads before melting, the probability of bridging after reflow is greater. Therefore, good resistance to cold and heat collapse is particularly important. Choosing the appropriate solder paste is an important way to avoid bridging, reduce rework volume, and improve production efficiency and product reliability.

Secondly, the viscosity of the solder paste of JJY changes little and it has a long service life. The change in viscosity will lead to variations in the print volume, which is particularly significant during the printing process. Therefore, maintaining a relatively stable viscosity is crucial for ensuring the consistency of solder joints. In most cases, the viscosity of lead-free no-wash solder paste increases along with a decrease in viscosity. For instance, when the solder paste dries, it almost loses its viscosity. During insertion, the solder paste may be pushed off due to loss of adhesion, resulting in missed soldering. Lead-free no-wash solder paste has excellent soldering performance and can exhibit appropriate wettability in different parts. It can meet the requirements of welding equipment of different grades, does not need to complete welding in a nitrogen-filled environment, and still shows good welding performance within a wide range of reflow oven temperatures. There is very little residue after welding, the color is very light and it has a relatively large insulation resistance, and it will not corrodePCBIt can meet the requirement of being washable.

How to purchase JJY solder paste

First of all, we suggest that you purchase JJY's products through official channels as much as possible. This can ensure quality and provide better after-sales service.

Second, when purchasing solder paste, pay attention to the appearance of the packaging. Although packaging does not represent quality, generally speaking, high-quality solder paste will adopt better packaging. Such packaging will have a psychological effect on consumers. For example, when consumers compare two products with different packaging, they tend to choose the one with a better appearance. In addition, solder paste produced by regular manufacturers will all be marked with detailed information, such as the true alloy composition and particle size of the solder paste, the amount of flux, batch number, production date, and packaging weight and other basic information. If there are quality problems, it can be better traced and verified.

Thirdly, when choosing JJY solder paste, we should take our own actual situation into consideration. Different types of solder paste have different parameters, such as different requirements for temperature and melting point. When making a purchase, it is necessary to pay attention to the characteristics of the items to be soldered and consider whether the selected solder paste is a general type or one with higher parameter and performance requirements.

As a 15-year-old veteran solder paste manufacturer, JJY has been dedicated to the research and development and production of solder paste for many years. The quality of the solder paste is stable, without solder bonding, false soldering or establishing a reputation. No residue, Wuxi beads, bright, full, firm solder joints with excellent electrical conductivity. If you have any needs, please feel free to contact us.
