POTENTIAL BENEFITS OF SABIC’S ADVANCED OPTICAL THERMOPLASTIC RESINS
SABIC has several decades of history in supplying thermoplastic polymers in the opto-electronics industry. Optical elements in data communication and mobile applications play a critical role for seamless connectivity of electronic devices and back-end infrastructures.
OUR PORTFOLIO MEETS VARIOUS REQUIREMENTS OF THE OPTICAL INDUSTRY
SABIC offers a broad portfolio of ULTEM™ and EXTEM™ resins to address material requirements for the photonics industry, including the ability to withstand the high heat of typical opto-electronic solder processes.
ULTEM Polyetherimide Resin
ULTEM resins are near infrared transparent, amorphous thermoplastic resins with a low thermal expansion coefficient (CTE). They have been used for (multi mode) optical lens assemblies in photonics for decades based on a perfect properties fit for this application area.
The new ULTEM 3310TD resin offers ~ 30% reduction in CTE while retaining optical transmission and is well-suited where extra tight alignment tolerances are required, like lenses for single mode optics in data centers.
EXTEM Polyimide Resin
EXTEM resins offer superior heat resistance with near infrared transparency.
They can maintain stiffness and dimensional stability for mounting of parts and modules in a PCB assembly with SAC/SMT reflow soldering (245 - 260°C) process according JEDEC J-STD-020A.
EXTEM™ RESIN WELL-SUITED FOR ONBOARD OPTICAL INTERCONNECTS
Trends in improved user experience, functionality and connectivity are driving both higher bandwidth and speed. Is the industry we know moving from pluggable to co-packaged solutions? Whichever path you follow, we might have the right material for you.
CASE STUDY EXTEM™ RESIN IMPACT OF REFLOW SOLDERING & HYDRO AGING
Key test results using 5 parts are shown in the graph above.
• After 3 times reflow, the optical interconnects show no blistering while maximum signal loss was only 0.4dB.
• Hydro aging for 1000 hours did not result in haziness or any other visual defect, and signal loss did not exceed 1 dB.
These results are well within OEM specifications that SABIC used as a reference.
EXTEM™ RH RESIN SERIES WELL-SUITED FOR OPTICAL SENSING
Today, sensors are widely used in a growing number of applications. Some of these are proximity sensors, 3D sensing cameras and biometric monitoring devices. These application spaces keep growing at a high rate and upgraded functionalities require higher lens complexity.
ANTI-REFLECTIVE COATINGS TO IMPROVE EXTEM™ RESIN OPTICAL TRANSMISSION
Anti-reflection coatings (ARC) reduce first surface reflection losses, improve contrast and boost the transmission through the optical surface. By applying these coatings on EXTEM™ resin, more light is transmitted through the lenses, enabling a higher sensitivity for optical sensors or lower signal losses for fiber optical connectors.
In the assembly of opto-electronic packages adhesives play a key role to bond lenses and substrates. Using mainstream assembly techniques for mass production of optical modules, SABIC tested a wide range of adhesives in collaboration with DELO. This includes transparent, low-outgassing and tension-equalizing adhesives to compensate for thermal expansion differences between EXTEM resin and substrates.
