[0026] [Example One]
[0027] To enable those skilled in the art to understand the present invention in more detail, the present invention will be described in detail below with reference to the accompanying drawings.
[0028] Such as figure 1 Said, figure 1 It is a flip-chip plastic packaging structure with a heat dissipation structure in an embodiment of the present invention, wherein the structure includes:
[0029] Chip 1
[0030] The substrate 2 is provided with the chip 1 on the first surface 21 of the substrate 2;
[0031] A height-limiting block 3, which is arranged on the first surface 21 of the substrate 2;
[0032] Specifically, the height-limiting block 3 may be a material such as metal, plastic, silicon, etc. The height-limiting block 3 is mainly used to support the heat dissipation plate 4, and the height-limiting block and the chip are set at the same height to ensure The heat dissipation plate 4 is parallel to the substrate 2. Further, both the height limiting block 3 a...
Example Embodiment
[0044] [Example 2]
[0045] Such as Figure 2-7 As shown, the embodiment of the present invention also provides a flip-chip plastic packaging manufacturing method with a heat sink, the method including:
[0046] Step 110: soldering the chip 1 to the first surface 21 of the substrate 2;
[0047] Specifically, step 110 may specifically include bonding the chip to the substrate by flip-chip bonding.
[0048] Step 120: Fill the undercoating material 7 at the bumps of the chip 1;
[0049] Step 130: Pasting a height-limiting block 3 on the first surface 21 of the substrate 2 so that the height-limiting block 3 is the same height as the chip 1;
[0050] Step 140: Fill the first surface 21 of the substrate 2 with a plastic molding resin 5, press the heat dissipation plate 4 on the surface of the plastic resin 5, and drain the air bubbles in the resin to cure;
[0051] Specifically, the plastic molding resin 5 is filled in the first space formed by the first surface 21 of the substrate 2, the hei...
