  • Patent number: 9960329
    Abstract: Methods and apparatus are provided to improve long-term reliability of LED packages using reflective opaque die attach (DA) material. In one novel aspect, a protected area surrounding edges of the LED is determined. The DA is applied to the determined protected area by a dispense process, a stamping process, or a screen printing process, such that the effect of temperature degradation is reduced. A heat distribution model is used to determine the protected area, which is between edges of the LED and a predefined isothermal line where the temperature is 1/e that of the temperature at edges of the LED. In another embodiment, the protected area is further based on a spreading ratio of the substrate size to the LED size. In another novel aspect, with multiple LEDs in the LED package, the spreading ratio is further based on pitch distances to the immediate adjacent LEDs and the substrate boundary.

  • Patent number: 9896330
    Abstract: A packaged micro-electro-mechanical system (MEMS) device (100) comprises a circuitry chip (101) attached to the pad (110) of a substrate with leads (111), and a MEMS (150) vertically attached to the chip surface by a layer (140) of low modulus silicone compound. On the chip surface, the MEMS device is surrounded by a polyimide ring (130) with a surface phobic to silicone compounds. A dome-shaped glob (160) of cured low modulus silicone material covers the MEMS and the MEMS terminal bonding wire spans (180); the glob is restricted to the chip surface area inside the polyimide ring and has a surface non-adhesive to epoxy-based molding compounds. A package (190) of polymeric molding compound encapsulates the vertical assembly of the glob embedding the MEMS, the circuitry chip, and portions of the substrate; the molding compound is non-adhering to the glob surface yet adhering to all other surfaces.
