Copyright ⓒ Seoul Semiconductor Co., Ltd. www.seoulsemicon.com Acrich Application Note for MJT SAW8LH0A(Warm), SAW0LH0A(Cool) Introduction Acrich2 Modular Solutions Overview Seoul Semiconductor has introduced a family of standard modules called the Acrich2. These modules consist of the latest generation of LEDs that use the Patented Acrich die technology and the newly developed Acrich Integrated Circuit (Acrich IC), that provides a simple off line converter solution with multi channel current control and doesn't require temperature sensitive passive components like electrolytic capacitors. Using these standard modules as reference designs, it is a simple task to create custom modules to meet a wide variety of applications. This application note describes the operation of the Acrich IC and provides implementation details for creating custom Acrich module configurations.

Component 1.4 Handling Precautions During processing, mechanical stress on the surface should be minimized as much as possible. Sharp objects of all types should not be used to pierce the sealing compound. In general, LEDs should only be handled from the side. By the way, this also applies to LEDs without a silicone sealant, since the surface can also become scratched. When populating boards in SMT production, there are basically no restrictions regarding the form of the pick and place nozzle, except that mechanical pressure on the surface of the resin must be prevented. This is assured by choosing a pick and place nozzle which is larger than the LED’s reflector area. Silicone differs from materials conventionally used for the manufacturing of LEDs. These conditions must be considered during the handling of such devices. Compared to standard encapsulants, silicone is generally softer, and the surface is more likely to attract dust. As mentioned previously, the increased sensitivity to dust requires special care during processing. In cases where a minimal level of dirt and dust particles cannot be guaranteed, a suitable cleaning solution must be applied to the surface after the soldering of components. SSC suggests using isopropyl alcohol for cleaning. In case other solvents are used, it must be assured that these solvents do not dissolve the package or resin. Ultrasonic cleaning is not recommended. Ultrasonic cleaning may cause damage to the LED. Please do not mold this product into another resin (epoxy, urethane, etc) and do not handle this product with acid or sulfur material in sealed space. Avoid leaving fingerprints on silicone resin parts. 1.5 Optical Characteristics & Mechanical Files support Optical characteristics and mechanical file for MJT5050 are available on the Seoul-semiconductor website at www.seoulsemicon.com Copyright ⓒ Seoul Semiconductor Co., Ltd. 5 www.seoulsemicon.com 1.
