SMT red glue is a single-component epoxy resin adhesive stored at room temperature, which rapidly solidifies upon heating.
Even in ultra-high-speed microdot dispensing, it maintains a stable shape without trailing, overflowing, or collapsing. Its viscosity characteristics, known as 'shear thinning,' and low moisture absorption make it suitable for conventional screen printing applications. The shape of the adhesive dots is easily controllable, ensuring stable storage and excellent heat shock resistance and electrical performance.
The primary function of red glue is to enhance the adhesion of components, preventing displacement or detachment during the reflow process, and ensuring the stability of large components. It is predominantly used in SMT (Surface Mount Technology) assembly and wave soldering processes, with applications spanning industries such as consumer electronics (e.g., smartphones, watches), household appliances, automotive electronics, and others.
In the process of red glue dispensing, key process parameters ensuring dispensing effectiveness include dispensing quantity control, dispensing force, dispensing precision, dispensing speed, and single-point dispensing volume. Equipment operating speed is crucial for maintaining dispensing efficiency.
The increasing integration density of PCBs results in reduced dispensing space and an increased number of dispensing locations. Consequently, the industry trend in the red glue sector revolves around achieving smaller single-point dispensing and enhancing equipment speed for frequent acceleration and deceleration movements. This trend emphasizes smaller single-point dispensing, faster spatial movement speeds.
