Description

[Technical Field]

The invention belongs to the technical field of fluid control, and in particular relates to an injection dispensing valve and a dispensing method thereof.

【Background technique】

The use of injection valves has become more widespread in industrial product packaging processes. The injection valve sprays a small amount of high-viscosity fluid (flux, conductive paste, epoxy resin, adhesive, etc.) into a suitable position of the workpiece (chip, electronic component, etc.) to achieve mechanical or electrical connection between the components. The amount of jet flow is determined by factors such as nozzle diameter, fluid pressure, fluid viscosity or injection pressure.
