Rare Earth Cerium Solder Paste Technology
Innovative lead-free solutions for modern electronics manufacturing
Introduction to Solder Paste
Solder paste is a new type of welding material that emerged with Surface Mount Technology (SMT). It is a paste-like mixture composed of solder powder, flux, and other surfactants, thixotropic agents, and additives. When working with this material, it's often necessary to move solid rosin paste to smaller box for precise application and storage efficiency.
Primarily used in the SMT industry for soldering electronic components such as resistors, capacitors, and ICs on PCB surfaces, solder paste plays a critical role in modern electronics manufacturing. The ability to properly move solid rosin paste to smaller box ensures that manufacturers can maintain the material's integrity while optimizing workflow efficiency.
Composed mainly of flux and solder powder, solder paste has evolved significantly over the years. As electronic devices become smaller and more complex, the quality and characteristics of solder paste have become increasingly important. Many production facilities now regularly move solid rosin paste to smaller box to accommodate more precise application requirements in miniaturized electronics.
Composition of Solder Paste
Flux Components and Their Functions
Activators
This component primarily functions to remove oxide substances from the surface of PCB copper pad and component welding parts. It also has the effect of reducing the surface tension of tin and lead. Proper storage is essential for maintaining activator effectiveness, which is why many technicians prefer to move solid rosin paste to smaller box containers that offer better sealing properties.
Thixotropic Agents
This component mainly adjusts the viscosity and printing performance of the solder paste, preventing phenomena such as tailing and adhesion during printing. When you move solid rosin paste to smaller box, the thixotropic properties help maintain the paste's consistency, ensuring it's ready for application when needed.
Resins
This component primarily increases the adhesiveness of the solder paste and provides protection against re-oxidation of the PCB after soldering. This component plays an important role in fixing components. When you move solid rosin paste to smaller box, the resin content helps maintain the paste's adhesive properties during storage.
Solvents
This component is the solvent for the flux components, regulating uniformity during the mixing process of the solder paste and having a certain impact on the service life of the solder paste. When you move solid rosin paste to smaller box, proper sealing is crucial to prevent solvent evaporation that can compromise the paste's performance.
Solder Powder
Also known as tin powder, solder powder is mainly composed of tin-lead, tin-bismuth, or tin-silver-copper alloys. The particle size, shape, and uniformity of the solder powder significantly affect the performance of the final solder paste. Many manufacturing protocols specify the optimal conditions when you move solid rosin paste to smaller box to preserve the integrity of these powder particles.
Industry Developments and Trends
With industrial development and progress, traditional solder pastes containing large amounts of lead have been gradually replaced due to the significant amount of fumes they generate. The adoption of lead-free solders has become an inevitable trend in the development of welding materials, driven by environmental concerns and health regulations worldwide.
Lead-free solder pastes offer numerous advantages, including reduced environmental impact, improved worker safety, and compliance with international regulations such as RoHS. As manufacturers transition to these newer formulations, proper handling techniques—including when and how to move solid rosin paste to smaller box—have become essential knowledge for production teams.
Environmental Impact Comparison

The shift toward lead-free solder pastes has also driven innovations in application techniques. Proper storage and handling, including knowing when to move solid rosin paste to smaller box for specific manufacturing stages, has become critical for maintaining product quality while maximizing efficiency. Manufacturers are investing in training programs to ensure their teams understand the unique properties and requirements of these new formulations.

Preparation Method of Rare Earth Alloy Powder
Add 4-10 parts by weight of cerium sulfate to 80-100 parts by weight of water, stir evenly, then add 2-3 parts by weight of sodium silicate. Raise the temperature to 50-60°C, add ammonia water dropwise to adjust the pH to 7.8-9, and let it stand for 10-20 minutes while maintaining the temperature. This initial step is crucial for activating the rare earth components. Many operators prefer to prepare smaller batches when they need to move solid rosin paste to smaller box for specialized applications.
Take 3-5 parts by weight of hectorite and add it to 6-10 parts by weight of ammonia solution with a concentration of 28-30%. Stir and mix for 6-10 minutes, then add 40-50 parts by weight of tin powder and 1-2 parts by weight of dibutyl phthalate. Maintain the temperature at 50-60°C and stir for 10-13 minutes. This step ensures proper integration of the rare earth elements with the base metals.
Mix all the processed raw materials, add 0.5-1 part by weight of sodium dodecylbenzene sulfonate, stir and disperse at 400-500 rpm for 3-4 minutes. Dry at 100-110°C and mill to a fineness of 40-60μm.
