AI Technical Summary

Technical Problem

During PCB board inspection, static electricity can cause dust to adhere, affecting the product's appearance and function, and poses a risk of spark discharge. This is especially true in flammable and explosive environments, where it can lead to accidents and damage to people and precision instruments.

Method used

Design a plasma dust removal mechanism for a test fixture. Utilize a plasma generator and a fan bar to generate a plasma airflow, adsorb and peel off dust from the PCB board, and collect the dust through a dust collection component to avoid static electricity accumulation.

Benefits of technology

It effectively removes dust from PCB boards, improves product quality and safety, optimizes the working environment, reduces enterprise operating costs, and minimizes damage to precision equipment.
