Thin-walled LEDs for mobile phones

-
he Japanese plastic converter Nissei Industries Ltd. has produced the thinnest low-profile side view light-emitting diodes (LEDs) specially designed for thin-profile mobile phones. This ultra-thin LEDs are 0.4mm high and are made from a 22% mineral filled, light-stabilized, high-reflectivity polyphthalamide (PPA) material supplied by the Belgian material producer Solvay Advanced Polymers i.e. Amodel™ A-4422 LS WH118. This grade allows to fill very thin walls and runs in high-cavity molds up to 264 cavities. It has a fast crystallization rate and offers higher flow, faster cycles, lower flash and greater overall performance than conventional glass fiber reinforced polyamide-9T materials. The PPA ultra-thin LED reflector cups are injection molded onto the lead frame by Nissei Industries and supplied to a Taiwanese packaging company that produces LEDs for the mobile phone industry.

Today's KNOWLEDGE Share Ever wondered how we can reduce plastic pollution in India? The Mysuru-based Defence Food Research Laboratory (DFRL), affiliated with the DRDO, has launched an eco-friendly remedy with the introduction of biodegradable water bottles. Crafted from sustainable Polylactic acid (PLA) material, these bottles not only combat plastic waste but also contribute to reducing the overall carbon footprint. The best thing about this bottle is its all-encompassing sustainability approach – the bottle, cap, and label are all compostable. This innovation, derived from 100% bio-based and renewable sources, sets us on a path towards environmental conservation and fosters a greener and more sustainable future.

Today's KNOWLEDGE Share:High and low shear rate changes in Rheology

-

Today's KNOWLEDGE Share If a relatively high Mw grade flows from thin to thick, as shown in the picture, and if the time needed to fill the thick section is way shorter than the average polymer relaxation time, the polymer will not be able to reach its higher viscosity (corresponding to higher thickness/lower shear-rate). I am assuming here the polymer reached equilibrium low viscosity in the thin section, say for instance because it is much longer. Any pressure prediction not accounting for transient rheology would then overpredict the pressure to fill.Of course the diverging flow will further complicate the situation and mess with the molecular orientation created in the thin section, but to what extent ? Since this is more of a reasonable "conjecture", don't take this for granted, and discuss or share your opinion in the comments. There are hundreds of Rheology papers on the "4:1 contraction flow". Not sure I have ever seen any on the..."1:4 expansio
