UV-tuned release-sheet adhesion prevents plating erosion from hydrogen gas, then enables clean circuit pattern peeling and transfer.
Pattern transfer sheet includes trace marks and working window marks to monitor laser beam position and power during paste deposition.
Printed transfer paper serves as a disposable mask for selective chemical etching, reducing fabrication complexity and equipment costs.
Hot or cold stamping forms circuits directly on supporting bodies, eliminating polymer films that cause yield loss and high material costs.
