A carrier-free land grid array (LGA) Integrated Circuit (IC) chip package and a preparation method thereof are provided. The IC chip package includes: an inner pin, an IC chip, a pad, a bonding wire, and a mold cap. The inner pin is designed to be a multi-row matrix form at a front side of the package, and is designed to be an exposed multi-row approximate square-shaped circular gold-plated contacts at a back side; the IC chip is provided on the inner pin, the inner pin is adhered to the IC chip with an adhesive film sheet, the pad on the IC chip is connected to the inner pin by the bonding wire, and the mold cap encircles the adhesive film sheet, the IC chip, the bonding wire, and edges of the inner pin, so as to form a whole circuit. The present invention adopts approximate square-shaped spherical array contacts, thereby having a simple and flexible structure, and achieving a desirable heat-dissipation effect. A cooper lead frame (L/F) has a high yield, and reduces the material cost. The L/F is used to replace a ceramic substrate, PCB substrate, or BT substrate, thereby saving the complicated layout design, shortening the designing and manufacturing cycle, accelerating the trial production course, and enabling the product to be early listed to obtain market opportunities.

The present invention discloses a quad flat no lead package and a production method thereof. The quad flat no lead package comprises a lead frame carrier consisting of a carrier pit and three circles of leads arranged around the carrier pit, wherein the three circles of leads respectively consist of a plurality of leads that are disconnected mutually; an IC chip is adhered in the carrier pit; and an inner lead chemical nickel and porpezite plated layer is plated on all the leads; the inner lead chemical nickel and porpezite plated layer is arranged in the same direction as the IC chip; the IC chip is connected with the inner lead chemical nickel and porpezite plated layer through a bonding wire; and the IC chip, the ends of all the leads plated with the inner lead chemical plating nickel and palladium metal layers and the bonding wire are all packaged in a plastic package. The quad flat no lead package is manufactured through the following steps of: thinning and scribing a wafer; manufacturing a lead frame; loading the chip; performing pressure welding and plastic packaging; performing post-curing; printing; electroplating; separating the leads; separating a product; and testing/braiding. According to the package, the problems of few leads, long welding wire, high welding cost and limited frequency application during single-face packaging of the existing normal quad flat no lead package are solved.

摘要:
The present invention relates to a two-dimensional array code. The two-dimensional array code comprises a plurality of code characters arranged into a two-dimensional array, wherein each of the code characters corresponds to a bit group representing information; and a locating mechanism, for defining size and/or direction of the two-dimensional array arranged by the code characters, wherein each of the code characters belongs to one of a plurality of character groups, characters in each of the character groups have at least a identical or similar feature, and characters belong to a same character group are mapped to a same bit group. According to the present invention, at least one of the plurality of character groups comprises two or more code characters. The present invention greatly reduces the cost for issuing a two-dimensional code, and significantly increases the user convenience. This two-dimensional array code has high compatibility for user mobile terminals. In addition, the entire system apparently improves its safety and stability, and is suitable for the present network application environment.
