Description
(1) technical field
The utility model relates to a kind of resin circuit board chip-flip lockhole of falling T heat dissipation block externally connected with radiator encapsulating structure.Belong to the semiconductor packaging field.
(2) background technology
The radiating mode of traditional Chip Packaging form mainly be to have adopted the Metal Substrate island of chip below as heat radiation conduction instrument or approach, and there is following not enough point in the heat radiation of this conventional package mode conduction:
1, Metal Substrate island volume is too little
Referring to Fig. 1 and Fig. 2, Fig. 1 is Metal Substrate island baried type chip-packaging structure schematic diagram in the past.Fig. 2 is the vertical view of Fig. 1.By Fig. 1 and Fig. 2 as can be seen, baried type chip-packaging structure in Metal Substrate island was made up of pin 4 and wire 5 in Metal Substrate island 1, conduction or nonconducting heat conduction bonding material I 2, chip 3, the metal in the past.The Metal Substrate island is in the conventional package form, in order to pursue the reliability safety of packaging body, nearly all adopted the Metal Substrate island to be embedded in the packaging body, and in limited packaging body, to imbed the interior pin (as shown in Figures 1 and 2) of metal of Metal Substrate island and signal, power supply conduction usefulness simultaneously, very the little so effective area on Metal Substrate island and volume just seem, and the function of the heat radiation of high heat also will be served as in the Metal Substrate island simultaneously, will seem deficiency more.
2, baried type Metal Substrate island (as shown in Figures 1 and 2)
The Metal Substrate island is in the conventional package form, in order to pursue the reliability safety of packaging body, nearly all adopted the Metal Substrate island to be embedded in the packaging body, and the Metal Substrate island is about dependence or four fine support bars in corner fix or support metal Ji Dao, also because the characteristic of this fine support bar, the heat that has caused the Metal Substrate island to be absorbed from the chip, can't conduct out from fine support bar fast, so the heat of chip can't or be transmitted to the packaging body external world fast, caused the life-span quick aging of chip even burn or burnt out.
3, Metal Substrate island exposed type
Referring to Fig. 3 and Fig. 4, Fig. 3 is Metal Substrate island exposed type chip-packaging structure schematic diagram in the past.Fig. 4 is the vertical view of Fig. 3.By Fig. 3 and Fig. 4 as can be seen, exposed type chip-packaging structure in Metal Substrate island was made up of pin 4 and wire 5 in Metal Substrate island 1, conduction or nonconducting heat conduction bonding material I 2, chip 3, the metal in the past.Though expose on the Metal Substrate island, can provide also will good heat-sinking capability than the heat sinking function of baried type, because the volume on Metal Substrate island and area still very little in packaging body, so heat dissipation capability can be provided, still very limited.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and providing a kind of can provide heat dissipation capability the strong resin circuit board chip-flip lockhole of falling T heat dissipation block externally connected with radiator encapsulating structure.
The purpose of this utility model is achieved in that a kind of resin circuit board chip-flip lockhole of falling T heat dissipation block externally connected with radiator encapsulating structure, include chip, the single or multiple lift resin circuit board that is carried of chip below, the metal coupling that chip is used to the signal interconnection of single or multiple lift resin circuit board, conduction between chip and the described single or multiple lift resin circuit board or nonconducting heat conduction bonding material I and plastic-sealed body, above described chip, be provided with radiating block, this radiating block has lockhole, is equipped with conduction or nonconducting heat conduction bonding material II between this radiating block and the described chip; Be provided with radiator above described radiating block, described radiator is fixedlyed connected with radiating block by described lockhole with screw, and described radiating block is inverted T-shape structure.
The beneficial effects of the utility model are:
The utility model passes through addition radiating block above chip, and sets up radiator outside plastic-sealed body, serves as the function of the heat radiation of high heat, can provide heat dissipation capability strong, makes the heat of chip can be transmitted to the packaging body external world fast.Can be applied in and make it become height or superelevation heat radiation (High Thermal or Super High Thermal) ability on the packaging body of general packing forms and the packaging technology, can become SHT-FBP/QFN as FBP can become SHT-QFN/BGA and can become SHT-BGA/CSP and can become SHT-CSP ...Avoided the life-span quick aging of chip even burn or burnt out.
