By heating and applying pressure under vacuum conditions, it is possible to achieve bubble-free bonding, which is difficult to accomplish at room temperature and atmospheric pressure.
We have introduced a vacuum heat press machine that can apply pressure in a vacuum state and perform lamination processing for product manufacturing. Processing in a vacuum state is used for various product applications, such as surface treatments like vapor deposition and the bonding of glass and silicon (Si) wafers. Since there is almost no air present, it allows for special processing that cannot be done under atmospheric conditions. ■ Outgassing during lamination using adhesives or adhesive tapes ■ Bubbles when laminating substrates with uneven surfaces using roll laminating If you are facing challenges like these, our vacuum heat press processing may offer a solution. We can perform special processing that is difficult under normal room temperature and pressure conditions, such as reliable bubble-free sealing and vacuum pouching. It is also possible to bond materials treated with plasma without using adhesives. If you are experiencing issues with bubbles during lamination, please contact us at Oatis.
