Abstract

The invention discloses a chip plastic package structure manufacturing method and relates to the technical field of semiconductors. The method includes the steps that a chip and height limiting blocks are attached to the surface of a PCB; the chip is arranged on the PCB in a bonding mode through a lead, the space formed by the chip, the height limiting blocks and the PCB is filled with plastic package resin, a plastic package structure is formed through press fit of a plastic package plate, and curing is performed; a plastic package plate is removed; the plastic package structure is cut to form independent plastic package devices. Due to the use of the height limiting blocks, a high-precision packaging mold is not needed, and the low-cost advantage is achieved.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a method for manufacturing a chip plastic packaging structure. Background technique [0002] In the field of semiconductor technology, commonly used chips are bonded to the surface of the PCB, among which wire bonding is more commonly used. [0003] But, those skilled in the art find that there is following deficiency in the prior art through research: [0004] Although the conventional method in the prior art is simple and easy to mass produce, it needs to make high-precision molds, and different molds need to be made for different packaging heights. Due to the high cost of making molds, the manufacturing cost is high. Contents of the invention [0005] The embodiment of the present invention provides a method for manufacturing a chip plastic packaging structure, which is used to solve the technical problem of high manufacturing cost of the wire bonding plastic packagi...
