Description
(1) technical field
The utility model relates to a kind of base island embedded chip formal dress rectangular heat dissipation block external radiator packaging 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
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 (as shown in Figures 3 and 4)
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 strong base island embedded chip formal dress rectangular heat dissipation block external radiator packaging structure.
The purpose of this utility model is achieved in that a kind of base island embedded chip formal dress rectangular heat dissipation block external radiator packaging structure, include chip, the Metal Substrate island of being carried of chip below, the interior pin of metal, chip to conduction or nonconducting heat conduction bonding material I and plastic-sealed body between wire, chip and the Metal Substrate island of the signal interconnection of the interior pin of metal, plastic-sealed body is imbedded on described Metal Substrate island 1, above described chip, be provided with radiating block, be equipped with conduction or nonconducting heat conduction bonding material II between this radiating block and the described chip; Be provided with metal heat sink above described radiating block, be equipped with conduction or nonconducting heat conduction bonding material III between this radiator and the described radiating block, described radiating block is square type 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.
