Semiconductor industry: Issues with the liquid application process between plastic films
We wanted to stack two plastic films and apply a film-forming material (liquid) evenly between the films, but we encountered the following problems.
・The coating must be applied at the exact timing when the liquid becomes uniform, and misalignment or variations in speed can easily cause unevenness or bias.
・If the film meanders or the tension is not consistent during transport, it will affect the spreading of the coating liquid.
・There are layout restrictions as we want to reuse existing equipment for the drying oven used after coating.
Examples and Uses
① Create a system that allows the coating liquid to accumulate evenly
・Designed to provide an optimal clearance (gap) between the roll and the sheathing, allowing the coating liquid to be uniformly distributed.
This structure stabilizes the thickness and distribution of the liquid, reducing the need for precise alignment of the bonding position.
②Prevention of overfeeding by tension control
- Introduces a torque limiter and other counter torque control mechanisms to prevent overfeeding of plastic film.
This prevents meandering and tension inconsistencies during transport, reducing the impact on the spreading of the coating liquid.
3) Cost reduction through design compatible with existing drying ovens
・The drying oven is designed flexibly so that existing equipment can be used as is.
No need for new installation, avoiding large capital investment
*We can also install a new drying oven if necessary.
Product Introduction
