Advanced Manufacturing Process
The superior performance of our flux paste for electronics is not only attributed to its innovative formulation but also to our advanced manufacturing process. Each step is carefully controlled to ensure the highest quality and consistency in every batch of flux paste for electronics.
Raw Material Preparation
The first step in producing our premium flux paste for electronics involves the careful weighing and preparation of all raw materials according to precise formulations. Each ingredient is inspected for purity and quality before entering the production process to ensure the final flux paste for electronics meets our stringent standards.
Thixotropic Agent Production
Hydrogenated castor oil, N, N-ethylene bis-stearamide, and dimethyl sulfoxide are added to a reaction vessel. Under pressure not less than 5Mpa, the mixture is heated to 150-180°C while stirring for 0.5-2 hours. The temperature is then reduced to 20-35°C at a rate of 5°C per minute to form the specialized thixotropic agent powder critical to our flux paste for electronics performance.
Initial Component Blending
Organic solvents, rosin, and activating agents are precisely measured and added to a reaction vessel. The mixture is heated to 60-70°C and stirred until completely homogeneous. This careful temperature control ensures that each component is fully integrated without compromising the integrity of any ingredients in our flux paste for electronics.
Final Component Integration
The temperature is reduced to 20-30°C, and all remaining ingredients are added to the mixture. The complete formulation is then stirred under vacuum conditions to ensure thorough integration without introducing air bubbles or contaminants. This step is critical for achieving the uniform consistency that characterizes our premium flux paste for electronics.
Precision Grinding
The final mixture undergoes specialized grinding to achieve the precise particle size distribution required for optimal performance. This grinding process ensures that our flux paste for electronics maintains consistent properties throughout its shelf life and performs reliably during application, even in the most demanding SMT processes involving fine-pitch components.
