(1) Assessment of rubber roll mounting quality
Industry: Displays, Prited boards, Lead frames, etc
Challenges: If the adhension of the rubber to the steel core of the lamination nip roll is poor or if the rubber is damaged, lamination defects occur.
Benefits of Prescale: Time saving, Quality improvemnet
(2) Measurement of squeegee pressure distribution during cream solder printing
Industry: Printed Circuit Board (PCB) electronic component mounting
Challenges: When cream solder is screen printed onto print substrates, any nonuniformity in the squeegee pressure distribution will result in uneven application of the cream solder.
Benefits of Prescale: Time saving, Material savings, Quality improvement
(3) 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
(4) Adjustment of molds and injection molding machines
Industry: Molding, Mold making, Injection molding machine manufacture
Challenges: Excessive contact pressure, the failure of parts to make necessary contact, or the generation of burrs may occur since molds are composed of multiple parts and dimensional errors of each part tend to accumulate in the thickness direction.
Benefits of Prescale: Longer mold life, Higher component yield, Malfunction analysis
(5) Checking mold contact and pressure uniformity of stacking or laminating machines
Industry: Manufacture of laminated ceramics, Ceramic substrates and packages, PCBs, Electronic components for automobiles and mobile phones, Laminated devices
Challenges: Need to press in extremely high precision to avoid changes in electrical characteristics due to problems of poor adhesion or non-uniform thickness, and to avoid electrical connection failures due to displacement of the electrode pattern.
Benefits of Prescale: Yield improvement, Quality improvement, Accuracy improvement
(6) Checking the water resistance of mobile phones and improving the stability of related production processes
Industry: Manufacture of mobile phones, smartphones, and tablet computers
Challenges: Need to ensure that uniform pressure is applied by the assembly jigs during the assembly of waterproof devices.
Benefits of Prescale: Yield improvement, Quality improvement, Accuracy improvement
(7) 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
(8) 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
(9) To check pressure uniformity between the polisher stage and polishing sheet of the Panel polishing equipment
Industry: LCDs production
Challenges: To prevent air bubbles may form it is very important to maintain sufficient, uniform pressure between the panel and the polishing sheet.
Benefits of Prescale: Reduce of low quality product loss, Time saving
(10) Preparing bonding (heat sealing) equipment for sealing aluminum laminate films for lithium batteries
Industry: Lithium ion battery
Challenges: If the heat bar is improperly balanced during the bonding process, defective adhesion of the aluminum film may result, causing electrolyte leakage and personal injury risks.
Benefits of Prescale: Time saving, Fewer defects
(11) Verification of pressure uniformity of vacuum heat pressure devices
Industry: Electronic components, OLEDs, Touchscreens, Print circuit boards, Equipment such as semiconductors that are used as manufacturing and development machines
Challenges: The devices are expected or required to maintain as uniform surface pressure as long as possible to improve the quality of processed products.
Benefits of Prescale: Reduce of pressure failure or yield, Quality improvement
