Table of contents
(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 improvement
(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) 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
(5) 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 improvemnet
