Enhanced Plasma Generation for Plasma Etching of Printed Circuit/Wiring Board

Electronic packaging was once the major industry in Hong Kong. A printed circuit board, or PCB, is used to mechanically support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper sheets laminated onto a non-conductive substrate. The most fundamental and essential process/step for high quality fabrication is etching and/or cleaning process. Plasma cleaning and pre-treatment of substrates prior to wire bond and epoxy mould is a common standard. The aim of the project is to enhance plasma generation for cleaning/etching large area printed circuit/wiring boards. This project will encourage manufacturers to establish research base in Hong Kong and provide employment opportunities for Hong Kong citizens.
