Which laminator do you recommend?
We suggest you use a laminator that controls: (1) temperature, (2) speed and (3) provides a 3mm opening in the jaw.
SKY laminating machines have proven to be some of the strongest and most reliable laminators we have tested. The SKY 335R6 Laminating Machine is the most appropriate in their product line. (Available at Amazon.com and other online resellers.)

Can I laminate the sheets with a hand roller with a hot plate?
No, the sheet cannot be placed on the warm hot plate as it will stick to the substrate and trap air between the SUEX and substrate. Air is permanently trapped in this manner.
The sheet cannot contact the substrate until just before entering into the rollers.
What is the shelf life of SUEX?
The shelf life of SUEX is one year from the date of shipment but generally – given your process and environmental conditions – you can continue to use it for a longer period of time.
How do I store SUEX and ADEX sheets?
We recommend storing SUEX and ADEX sheets in an air conditioned room, in the original packaging, away from light at 68˚ to 75˚ F, 18˚ to 25˚ C.
How do I cut SUEX and ADEX sheets?
We recommend you do not cut SUEX and ADEX sheets. We can send you sheets pre-cut to your specifications.
If you have to cut the sheets, we recommend that the sheets and cutting tool be heated to 50˚ to 60˚ C. See our cutting instructions for more details.
How do I eliminate “wafer bow”?
SUEX and ADEX films will bow after cure but adjusting the process conditions can minimize this. You can get more information about eliminating “wafer bow” in our Guidelines.
What aspect ratio can I obtain?
The aspect ratio increases with the thickness of the film, the aspect ratio is 4:1 for 10µm films to over 20:1 for 200µm films and above.
Are SUEX and ADEX films “optically clear”?
SUEX and ADEX films are transparent but are yellow to yellow-brown after processing. The higher the process temperature, the greater the color.
How do I improve adhesion?
Adhesion is dependent on the substrate, the film thickness, surface preparation, and resist process conditions. We can provide recommendations to improve adhesion for various substrates.
I have found "bubbles" in the SUEX sheets. What are they and how do I remove them?
These “bubbles” are actually indentations (pits/craters) in the surface of the SUEX resin and often this issue can be quickly resolved.
In the short term we recommend preheating the sheets at 50°-60°C for 5-10 minutes after removing the PET before lamination. This must be done on a flat surface in a clean-room environment. Allow the sheets to cool thoroughly to room temperature before continuing your process.
In the future, we will be changing the carrier sheets to avoid formation of these indentations. This will eliminate the need to preheat the sheets.
