Higher Quality. More Materials.
Your product never looked so good.


Efficient laser cutting of coverlay and flexible circuits.

The LodeStone system is a more accurate and flexible processing alternative for the efficient cutting and drilling of flexible materials. Its short pulse-width femtosecond laser results in low levels of carbonization and minimal heat affected zones, delivering the exceptional accuracy and tight tolerances required by processors driving new solutions to market.

LodeStone uses an ESI-designed femtosecond laser with proprietary fiber technology to avoid costly laser components and historical issues with short pulse width laser reliability. With low upfront cost and high-quality, responsive ESI service support, LodeStone enables you to consistently output ultra-high quality product with minimal headaches and low cost.

It is well-known that ultra-short pulse lasers can avoid issues associated with poor laser energy absorption due to its cold ablation mechanism. Inefficient energy absorption is a major cause of poor quality and low throughput in many materials. LodeStone’s femtosecond laser enables you to process a broader range of material with high quality and productivity.

Can’t achieve your customer’s tight tolerances and high accuracies with your mechanical process anymore? Tired of long lead times and high prices for your mechanical tooling? LodeStone cuts overlay and flexible circuits with equivalent quality and reliability while enabling you to meet your customer’s demanding lead time and quality requirements and avoiding costly tooling.
