Lamination pressure


This is a collection of examples of lamination pressure measurement using Prescale.
Five examples of Dry film resist (DFR) lamination, Backgrind tape lamination roller, Electrophotographic heat fixing parts, Film Attaching Equipment and Cover glass attaching equipment are posted.

Table of contents

(1) Checking adhesive pressure of dry film resist (DFR) lamination

Industry: Printed Circuit Board(PCB), Lead frames, Liquid crystal, etc
Challenges: Bubbles and wrinkes can be formed if the base material/dry film resist/lamination roll is not set up in balance or if the pressure is not adjusted to be uniform. 
Benefits of Prescale: Time saving, Material savings

(2)Verifying backgrind tape lamination pressure uniformity

Industry: Semiconduvtor Production
Challenges: If the lamination roller pressure distribution is not uniform, the backgrind tape can become wrinkled.
Benefits of Prescale: Time saving, Quality improvemnet

(3)Maintaining high rendering quality by ensuring pressure uniformity during heat fixing

Industry: Manufacturing/maintenace services of office equiment
Challenges: If the pressure between a heating roll and a pressing roll is not uniform, defective fixing or distortions in the paper may occur.
Benefits of Prescale: Saving time and labor for defect analysis and adjustment

(4)Checking drum (roller) pressure uniformity when attaching functional films(OCA, AG, AR, polarizing plates, etc.) to cover glass and touch panels

Industry: Touch panels and LCDs
Challenges: If the pressure balance during this process is incorrect, air bubbles, wrinkles, positional displacement and other errors may occur, causing product failures.
Benefits of Prescale: Quality loss prevention, Time loss prevention

(5)Checking roller pressure uniformity when attaching the cover glass to touch panels or LCDs.

Industry: Touch panels and LCDs
Challenges: Since precision attachment is required between these hard materials, uneven pressure during the attachment process can cause air bubbles and other probelms.
Benefits of Prescale: Quality loss prevention, Time loss prevention
