  • Patent number: 9416930
    Abstract: A process of manufacturing an LED lamp strip includes the steps of forming a plurality of through holes on an adhesive tape, mounting the adhesive tape to a top side of a scrollable lead frame, bonding a plurality of LED chips to the top side of the scrollable lead frame according to the positions of the through holes, packaging the LED chips respectively, and finally cutting the scrollable lead frame. In light of this, the LED lamp strip can be produced under the circumstances of low production cost and less production time.

  • Publication number: 20140299978
    Abstract: A quad flat non-lead package includes a chip, a chip carrier including a bearing surface adapted for the mounting of the chip, a plurality of leads mounted around the chip carrier and electrically connected to the chip, each lead having an opening located in an outer edge of a rear end thereof, and a molding compound formed on the chip, the chip carrier and the leads by compression molding to let the opening of each lead be exposed to the outside. The design of the openings of the leads can provide more tin-climbing area to improve soldering quality and yield, thereby lowering the manufacturing cost and facilitating testing after the soldering process. The invention also provides a lead frame for quad flat non-lead package.
