System and method for producing artwork for printed circuit boards |
| 摘要 |
A modulated laser beam is used to produce artwork for printed circuit boards. A second beam is scanned with the first to produce a reference signal in co-operation with a reference mask. The reference signal is adjusted in phase to compensate for system delays and used to control the scanning position of the main laser beam. |
