Screen printing for flexible circuits: the qualification checklist

In brief

A useful equipment conversation starts with the stack, not the machine model.

For FPC and other flexible electronics, specify the film type and thickness, printed chemistry, line geometry, required registration and downstream curing or lamination. These variables determine whether a roll fed or sheet process is appropriate.

LICHAO equipment supports PET, PVC, PC and flexible circuit boards among applications for its reel to reel automatic screen printer. It gives a 0.075–0.38 mm substrate thickness range and 0.1 mm repeat overprint accuracy. Those are equipment specifications; suitability for a particular conductor pattern must be proven with samples.

A practical trial records registration across the web, ink adhesion after curing, dimensional stability, and defect rates through downstream handling. Share a drawing and expected output when requesting a configuration review.

What should be verified before equipment selection?

Confirm the substrate, pattern dimensions, layer chemistry, registration target, curing route and expected throughput with representative samples.
