Overview
ORC Manufacturing specializes in ultraviolet exposure equipment. Its lineup covers contact mask aligners, projection exposure systems and laser direct imaging systems.
The main application is patterning the wiring of package substrates, flexible circuits and printed circuit boards, where pattern pitches keep shrinking as packages become denser.
Business: UV exposure systems for package substrates and printed circuit boards
Why it matters
- Package substrates for advanced chips need finer wiring than ordinary circuit boards, which raises the requirements on substrate exposure tools.
- Laser direct imaging writes the pattern without a mask, which helps when designs change often.
