GWEIKE Publishes New Guide to Selecting Laser Cutting Systems for FPC and PI Film

Jinan, China, August 17, 2026 - GWEIKE has published a new technical guide for manufacturers evaluating laser cutting equipment for flexible printed circuits, polyimide film and coverlay production. The guide provides a structured framework for comparing laser sources, vision positioning, platform layouts, production throughput and sample-test results before selecting an FPC laser cutting machine.

The full FPC laser cutting machine selection guide is available at:

Selection Starts With the Material Stack

FPC laser equipment is sometimes compared only by laser power, advertised accuracy or maximum scanning speed. GWEIKE's new guide recommends beginning with the complete material structure and the required production result instead.

Plain PI film, adhesive-backed coverlay, copper-clad laminate and finished flexible circuits present different processing challenges. Adhesive layers can affect residue, carbonization and delamination. Copper near the cutting path changes heat transfer and increases the importance of controlled energy delivery. Finished FPC products may also require cut features to align precisely with pads, conductors or panel fiducials.

As a result, a system that produces an acceptable outline on plain PI film may not be the correct configuration for adhesive-backed coverlay or a completed flexible circuit.

Comparing UV, Green and Ultrafast Laser Sources

The guide explains that wavelength and laser power should not be evaluated separately from pulse duration, spot size, beam quality, repetition rate, focus strategy and the complete material stack.

Conventional UV laser processing is often a practical starting point for PI film contours, coverlay windows, standard FPC outlines, prototypes and small-to-medium production batches. Green laser configurations can be evaluated for selected materials with suitable absorption characteristics.

Picosecond or femtosecond processing becomes more relevant when optimized UV processing still produces unacceptable heat effects, carbonization, adhesive residue, delamination or micro-feature defects. However, the higher investment associated with an ultrafast laser system should be supported by measurable improvements in edge quality, production yield or feature capability.

The guide therefore recommends comparing repeated sample results rather than assuming that the most expensive laser source is automatically the correct choice.

CCD Registration and Platform Configuration

CCD vision positioning becomes important when a cut must align with printed features, copper pads or panel fiducials. Flexible materials can shrink, stretch or rotate during printing, lamination and handling. A vision system must identify the actual panel position and convert the measured offset into a corrected cutting path.

The new guide also addresses single-platform and dual-platform equipment. A single working platform may be suitable for prototypes, lower production volumes and frequent job changes. A dual-platform configuration can reduce laser waiting time when loading and unloading represent a meaningful share of the complete production cycle.

Dual platforms do not automatically double production. The actual benefit depends on loading time, vision recognition, path compensation, cutting time, unloading and inspection.

Measuring Real Production Throughput

Maximum galvo scanning speed is not the same as accepted production output. GWEIKE recommends calculating the complete panel cycle, including material loading, fixture positioning, CCD recognition, path correction, laser processing, unloading and quality inspection.

Equipment suppliers should be asked to provide the complete cycle time for the buyer's production file, the number of finished parts per panel, demonstrated hourly output, continuous-production quality rate and the process parameters used during testing.

"FPC equipment selection should begin with the complete material stack and the required production result, not with laser wattage or maximum scan speed," said a GWEIKE application representative. "Repeated sample quality, registration accuracy and complete panel cycle time provide a more reliable basis for an investment decision."

Two Equipment Directions for Different Workflows

For FPC, PCB, rigid-flex board and thin electronic material cutting, the GWK-UV4065 provides UV and green laser configurations together with a dual-platform precision processing structure. It is intended for applications that require controlled thermal influence, fine contours and repeatable positioning.

For roll-to-sheet processing of FPC substrates, CVL coverlay, PI film, PET film, adhesive materials and composite flexible films, the GKS-0605D-PI combines picosecond processing, CCD positioning, automatic unwinding and dual-head, dual-platform operation.

Sample Testing Before Purchase

The guide recommends testing the actual production material instead of relying on a generic PI sample. Manufacturers should provide the complete layer structure, material and adhesive thickness, copper position, production drawing, required tolerance, acceptable edge condition and target hourly output.

A successful single panel does not demonstrate stable mass production. Evaluation should cover multiple panels, different panel positions, feature-to-fiducial alignment, carbonization, adhesive residue, delamination, cycle time and station-to-station consistency.

The final equipment configuration should be selected from repeated sample quality, measured accuracy, complete cycle time, process stability and total production requirements.
