DSM Engineering Plastics today announced the launch of Stanyl® LED 1551, the
latest grade of Stanyl used in plastic lead chip carriers (PLCC) for high
brightness LED’s. These LED’s are conventionally selected for back lighting
LCD display panels used in Mobile phones, PDAs, notebook PCs and hand held
devices.
The launch of Stanyl LED 1551 is in line with DSM’s drive to fully understand
customers’ emerging needs and quickly address trends in these fast changing
markets with new grades. Sanjay Jain, Product Manager – Stanyl, DSM
Engineering Plastics Asia Pacific, elaborates “According to our benchmark
testing of competitive grades, this is the best grade available for SMT PLCC
packages for side view and top view high brightness LEDs targeted at LCD
panels up to 16 inch size. This has been confirmed by key customers based on
their initial evaluations. This launch will extend this offering to all our
customers, who can benefit from this development to make their LEDs more
efficient and reliable”
Stanyl LED 1551 is a material which offers high initial brightness combined
with best in class retention of reflectivity under high heat and high humidity
conditions required for backlighting applications for use in mobile, hand held
devices and notebook PC applications. Further, due to Stanyl’s superior
thermal characteristics, it is perfectly suited to take the three cycles of
reflow soldering at a peak temperature of 260°C, and adhesion to either
silicon or epoxy resins used for encapsulating. Sanjay further states: “The
material also features faster cycling for increased productivity than
alternative PPA resins. This, along with it’s inherently high flow ensures
filling of low profile side view LED multicavity tools up to 220 cavities with
lowest possible cycle times. Adhesion is excellent to silicon/epoxy resins.
The material also shows best in class reflectivity retention when exposed to
UV wavelength as low as 250 nm. The present peak wavelength of Blue LED Chip
is around 460nm but in the future the trend is towards UV Chip having peak
wavelength close to 350nm.”
