Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic manufacturing equipment, in particular to a cleaning device for electric component after plastic encapsulation. BACKGROUND

[0002] Plastic encapsulation of electric components is a common method to protect them from external environmental factors such as moisture, dust and mechanical impact. The plastic encapsulation process forms a protective layer by encapsulating the electric components in plastic material, thereby extending their service life and improving their reliability.

[0003] After plastic encapsulation of electric components, contaminants such as release agents and plastic flash often remain on their surfaces. During production, transportation and assembly, electric components may be contaminated with dust, dirt and other impurities. These contaminants not only affect the appearance of the circuit board but also negatively impact the performance of the circuit, and even cause malfunctions. Cleaning electric components can remove contaminants, ensure good contact between wires and conductivity, thereby improving the overall performance of the circuit. Cleaning electric components can remove accumulated dirt and oxides, slow down the aging of the circuit and extend the service life of electronic products.

[0004] In the prior art, for electric components with mild contamination, soft brushes are used to brush off dust and impurities on the surface. For electric components with more serious contamination, cleaning agents are used for soaking, followed by soft brush scrubbing, then rinsing with clean water and drying. For electric components with dead corners that are difficult to access, ultrasonic vibration method is used to strip off contaminants from the surface of electric components, achieving the effect of cleaning. Traditional cleaning methods have low efficiency and using soft brushes for scrubbing can easily damage the pins, leading to failure of electric components.
