Product Introduction

Traditional mechanical punching or knife cutting methods often cause edge burrs, deformation, or misalignment, leading to yield loss and rework. Inte Laser’s FPC Window Cutting Equipment eliminates these problems by offering a clean, precise, and fully automated laser processing solution that ensures excellent consistency, productivity, and reliability.

This system is widely used in mobile electronics, communication devices, wearable products, and flexible displays, where ultra-fine precision and stable repeatability are essential.

Working Principle

The equipment employs a high-energy laser beam that focuses onto the FPC surface to selectively ablate or vaporize the polyimide (PI) insulation layer.
By precisely controlling the laser’s power, pulse width, and scanning path, the system removes the coverlay layer to form a “window” while preserving the copper foil and substrate integrity.

The high-precision motion platform and CCD vision alignment system ensure perfect positioning, while the auto-focus and beam control technologies guarantee uniform cutting depth and stable edge quality.
This laser-based approach provides superior control and reproducibility compared to traditional mechanical or CO₂-based cutting methods.

Advantages

Improved processing efficiency with the potential for achieving a 100% yield rate;

Can enhance the issues of excess adhesive in tradi-tional processes;

High window accuracy, which can prevent the prob-lem of pad misalignment in conventional procedures;

Can achieve a minimum pad size of 0.15mm.
