Table of contents

(1) 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

(2) Setting of vacuum laminator

Industry: Solar cells (Photovoltaic module manufacturing)
Challenges: If the press pressure is not even when this is done, defects will occur, such as damage to cells or wrinkles in the protective film.
Benefits of Prescale: Reduce of material loss, Time saving

(3) 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

(4) Ensuring high-quality thermocompression bonding by the application of uniform pressure

Industry: Manufacturing (e.g., Bonding equipment, MEMS, Silicon wafers, Compound semiconductors, CMOS image sensors)
Challenges: If the pressure applied to bond the wafers or substrates is not constant, problems such as defective sealing, uneven bonding strength, and pattern width unveness may occur.
Benefits of Prescale: Reduce the adjustment time and effort for investigating the cause

(5) Checking uniformity of cell lamination load distribution

Industry: Fuel cell manufacture
Challenges: Problems such as lower power generation efficiency or fuel leaks may occur if the clamp load is too low/high.
Benefits of Prescale: Lower defect rate, Higher quality, Better maintenance

(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
