Application of Plasma Cleaning in Three-proof Technology of Printed Board Assembly of Avionics Products
In order to solve the process problem of three-proof and anti-wetting of printed circuit board assembly of avionics products,the mechanism exploration,plasma cleaning experiment and reliability test are adopted,and the results show that plasma cleaning could significantly improve the surface activity and three-proof reliability of printed circuit board assembly of avionics products.Finally,it is concluded that the plasma cleaning speed is 40～50 cm/s and the cleaning head is 15～20 mm away from the cleaning surface,and it is completed within 2 hours after cleaning.Plasma cleaning can stably solve the three-proof process problem of anti-wetting of printed board components of avionics products.
