Laser via drilling system for flex PCB manufacturing.

Best-in-class high-volume FPC laser drilling machine for flexible PCB Manufacturing.

Via drilling for flex PCB laser processing. ESI 5335.

The 5335 is a perfect flex PCB laser processing solution for leading-edge flex circuit manufacturing customers. Now in service at the leading flex PCB manufacturing companies, the 5335 laser via drilling machine is a good fit for customers requiring production-oriented flex PCB via drilling for PCB laser processing. It is also a good fit for general micromachining customers looking to take advantage of the state-of-the-art laser processing technology and applied laser expertise built into the 5335 platform.

Utilizing ESI’s Third Dynamics™ technology, the 5335 delivers industry-leading capabilities for UV laser via drilling and is optimized for processing both flexible circuits and rigid-flexible printed circuit boards. It also addresses other high-accuracy laser processing applications such as routing, patterning, and skiving through a combination of ESI's patented compound beam positioning and solid-state optical technology.

The Model 5335’s low cost of ownership—along with its high-volume laser manufacturing focus—optimizes your laser processing and production capabilities and puts you in a better position to keep up with the increasingly demanding needs of industries such as consumer electronics, automotive and medical devices.
