According to The Gas Review, dry etching is being used increasingly in manufacturing processes for mounting semiconductors and printed-circuit boards (PCBs) used in electronic devices.
When creating multilayer flexible PCBs using polyimides, the previous wet etching process adversely affects the materials, causing faults, such as insufficient continuity in layer connections. Recent demands on these multilayer PCBs include reducing size and weight for usage in cellular phones and other consumer products. Usage in the popular advanced driver-assistance systems (ADAS’s) and other on-board applications is also being considered, and manufacturing is expected to continue increasing.
PCBs found in all sorts of electric devices
PCBs provide electronic circuit to a wide range of fields from consumer products, such as cellular phones and TVs , to precision machinery, such as automobiles and rockets. For the mounted semiconductor packages, they perform an important function by making electrical connections between components.
