Lasers speed up board production.

Lasers speed up board production.

A technology for writing conductor patterns directly on photoresist simplifies the manufacture of printed-circuit boards and also multiplies yields. If a laser beam is switched on and off as it scans, it can be made to trace a pattern on a light-sensitive material directly, without intervening steps...
