Most PCB manufacturers use a tedious process of manual film alignment with manual exposure machines. The machines require up to seven operators and cycle times in excess of one minute. WKK has created a solution to this problem.
Following the initial design concept, WKK assembled a team of specialists from around the world for systems development, including China, Germany, India, Singapore, and the United States. The resulting machine is covered by numerous US and international patents.
This paper will present data that demonstrates that the machine is capable of the fully automatic exposure of SM panels, including full four CCD camera alignment of the A/W, in extremely short times and with minimal temperature build-up that causes film distortion.
Data will be provided to demonstrate that the resulting image provides all of the functional and dimensional requirements for successful product utilization.
