Application Notes by Fuji Film: Available Documents List
This application pertains to the verification and adjustment of the correct contact pressure level (both in terms of magnitude and uniformity)
developed by calendering rolls, which are typical in machinery used in the paper industry. Proper calibration not only enhances the quality of the
processed product but also extends the operational lifespan of the rubber rolls and can often result in energy savings.
This document addresses typical issues in the packaging process where, using Prescale Film, it is possible to not only monitor the actual pressure
levels applied but also check for misalignment, scratches, or surface damage on sealing elements, among other things. This enhances the final
quality of the packaging process and significantly reduces the likelihood of potential leaks in the packaged product.
Prescale Film: Application Note n° 03 - Lamination Process
Lamination processes are used in various production contexts, typically involving the production of materials with calibrated thicknesses or the application of adhesive films,
where a uniform and defect-free surface finish is crucial. The Prescale Film has significantly facilitated both the verification of the proper setup of rubber rolls
(e.g., checking parallelism) and the detection of any surface defects they may have.
The document refers to the verification of the proper deposition of solder paste on printed circuits (SMD components) via screen printing masks. However, this
verification concept can be extended to other applications related to screen printing. Thanks to Prescale Film, it is possible to ensure that the "blade" responsible
for applying the material operates uniformly, without defects or localized excesses.
This application note also refers to the verification of production processes related to the manufacturing of printed circuit boards, as it assesses
the benefits derived from the use of Prescale film in conjunction with the lamination of DFR (Dry Film Resist) films onto the board intended to
become a printed circuit. In these terms, it will be possible to evaluate the correct adhesive pressure, the absence of bubbles and/or wrinkles,
etc.
Prescale Film: Application Note n° 06 - Head Gasket Inspection
This is probably the most significant application of Prescale Film in the automotive field. Specifically, before the advent of Prescale, without
complex and costly operational tests, it was difficult to quickly and effectively confirm the optimal separation between the various circuits
(exhaust gases, coolant, and lubricating oil), while also ensuring the correct seal between the cylinder head and the engine block.
This application is decidedly specific to the semiconductor microelectronics sector, as it refers to a phase in their production process. In fact,
Prescale Film has proven useful for verifying the correct contact pressure, uniformity, flatness, and parallelism (as well as the presence of
abrasive agents) in relation to CMP (Chemical Mechanical Polishing) heads used for polishing silicon wafers.
Another specific application in the semiconductor microelectronics sector. Thanks to Prescale Film, it is possible to verify that the protective film,
normally applied to silicon wafers (prior to cutting them into small chips), is correctly applied, avoiding wrinkles, bubbles, and insufficient
adhesion. It also allows for checking that the support is suitable for the wafer's thickness.
Prescale Film: Application Note n° 09 - Winding Tension Control
This application addresses all issues that may arise during the winding of produced materials. It is necessary to verify the correct tension of the
wound material, ensuring that the coil has the proper consistency while also preventing excessive tension that could lead to damage, defects, or
dimensional variations, which will typically concentrate in the inner core.
This Application Note also documents an additional use of Prescale Film in the automotive field, as it pertains to verifying optimal contact between
brake discs and pads. Uneven wear of parts, localized heating, reduced braking effectiveness, noise, and vibrations can now be prevented upstream,
thanks to a verification method that effectively facilitates proper tuning.
This application, typically associated with the paper industry but also common in the offset printing sector, involves using Prescale Film to check
the wear level of rubber-covered rollers. It highlights scratches, marks, uneven wear, indentations, roller ovalization, etc., allowing for
machine adjustments that enhance the final quality of the processing, while reducing wear and energy consumption.
Another specific application in the semiconductor microelectronics sector relates to the devices used for picking and handling chips (die collet
suction jig). Thanks to the use of Prescale pressure-sensitive film, it is possible to ensure that the contact area with the chip (picked up via
suction) is homogeneous and free from defects that could allow leakage, which can lead to inaccurate pickups and unsafe chip handling.
This application is also related to the microelectronics sector but pertains to the production of photovoltaic panels, specifically within the process
of vacuum lamination of solar cells for their attachment to the glass substrate. Thanks to Prescale Film, it will be possible to address issues
with non-uniform lamination pressure distribution, improving the final product quality and thus avoiding production defects.
Thanks to the Prescale pressure-sensitive film, it is possible to check the pressure distribution between the mold and die, ensuring that it is
uniform and free from areas of excessive or insufficient pressure. With this tool, not only can optimal tuning be achieved, but it also results
in superior performance and extends the operational life of the parts.
With reference to electrophotography used, for example, in photocopiers, Prescale Film has proven useful for verifying the correct pressure uniformity
for the hot fixing of the image composed through electrostatic photographic reproduction, in order to improve its final rendering. Thanks to
Prescale, it will be possible to check the uniformity of contact pressures both across the width of the roller and along its length.
Prescale Film: Application Note n° 16 - Pressures in Lamination and Stacking Machines
Multistate ceramic devices are made with layers of paste, complete with electrodes, which are connected by welding with a stacking machine. High
accuracy in positioning and correct adhesion between layers are required; otherwise, the electrical characteristics may change, leading to
potential poor contacts. Thanks to Prescale, it is possible to verify both the correct uniformity of contact in the mold and the uniformity of
the lamination pressure.
Prescale Film: Application Note n° 17 - Uniformity of Pressures in Wafer Bonding Processes
Wafer bonding enables the creation of electronic devices by joining two (or more) wafers or substrates, primarily achieved through thermobonding.
Adequate contact union is crucial, largely depending on the applied pressure; otherwise, poor contacts and issues such as 'defective sealing' and
pattern width irregularities may occur. Prescale Film has proven significantly useful for these applications.
Prescale Film: Application Note n° 18 - Distribution of Lamination Load for Fuel Cells
A fuel cell consists of multiple laminated cells stacked together, and for the assembled stack, a clamping load is applied between the end plates to
generate adequate compression. Too-low clamping pressures can lead to reduced efficiency and even fuel leaks; conversely, excessively high
clamping pressures can cause gasket materials to deteriorate too quickly. Prescale Film allows for verifying the actual load applied to each
individual cell.
Cell phones, becoming increasingly compact and thin, must now meet a growing demand for waterproofing. The assembly of sealed phones requires tighter
tolerances, with additional parts (e.g., gaskets), resulting in a complex assembly process that must be performed without defects, misalignments,
and with uniform assembly pressures. Prescale has proven particularly effective for these checks.
Prescale Film: Application Note n° 20 - Application of Functional Films in Touch Panels
The application of functional films on touch panels (e.g., OCA, AG, AR, etc.) is carried out by positioning and applying them with a drum roller,
which is rotated over the glass where the functional film is applied. If the pressure balance applied during this process is incorrect,
air bubbles, wrinkles, misalignments, and other defects may occur. Prescale has been advantageously used for fine-tuning these production
processes.
Prescale Film: Application Note n° 21 - Attachment of Cover Glasses for Touch Panels
The diversification of touch panels (e.g., smartphones, tablet PCs, handheld games, etc.) has increased the complexity of attaching materials such
as rigid cover glass to touch panels. Since precise attachment between these rigid materials is required, uneven pressure during the attachment
process can cause air bubbles and other defects. Prescale Film has been successfully used to fine-tune these assembly processes.
Prescale Film: Application Note n° 22 - Verification of Uniformity in Polishing Processes
In the production of LCDs, it is important to remove any surface irregularities, especially when additional films (e.g., polarization plate) are
to be applied. Therefore, surface polishing processes are carried out to prevent the formation of air bubbles and further deterioration of the
panel’s functionality. The polishing process must be applied with the correct pressure and uniformity, and Prescale Film has allowed for the
optimization of these processes.
Prescale Film: Application Note n° 23 - Verification of Production Processes for Lithium Batteries
When sealing gelatinous electrolytes typical of batteries, an aluminum laminated film is thermally bonded to the outer casing. The heating bar must
apply the correct pressure, properly distributed, to avoid defective adhesion that could lead to electrolyte leakage and potential user harm.
Prescale Film allows for verifying the correct and adequate thermal bonding pressure for these assembly processes.
Another application related to the production of lithium-ion batteries, where Prescale Film allows for verifying the correct parallelism,
uniformity of applied pressure, and the absence of indentations, scratches, or deformities on the rollers used for assembling the battery
electrode plates. These plates must be properly assembled, minimizing defects related to both the applied pressures and the surface conditions
of the assembly rollers.
Prescale Film: Application Note n° 25 - Application of Conductive Film for Photovoltaic Cells
Any incorrect positioning and bonding of the conductive film applied to photovoltaic cells results in significant production waste, as the conductive
film cannot be removed once applied. In this context, Prescale Pressure-Sensitive Film allows for the preliminary verification of the uniformity
of assembly pressures before proceeding with the final bonding process of the conductive film to the photovoltaic cell.
Prescale Film: Application Note n° 26 - Pressure Bonding Performed Under Vacuum
Another application related to the microelectronics sector, more generally concerning all processes that involve the application or assembly of parts
and/or films, such as those related to touch panels, OLEDs, fuel cells, etc., where it is essential that the pressure bonding processes
(performed in a vacuum and for extended periods) are uniform. Prescale Film has proven to be a valuable aid for these processes.
