New Description: [New Technology Field] This creation is about a package structure, especially a package structure with a separate package. [Prior Art] In addition to the earliest developed two-row vertical package (dual) In line package 'DIP) outside 'chip carrier, flip chip (FC), pin grid array (PGA), tape carrier, hermetic package , ball grid array (BGA), quad flat package (QFP), lead on chip (LOC), chip scaie package (CSP), Bare die, tape carrier package (TCP), etc. Regardless of which of the above packaging processes, it is usually through the potting process step. Generally, the 'filling process' is by molding, that is, the mold sandwiches the wafer carrier (ie, a printed circuit board having a plurality of wafers), and the wafer carrier is housed in the mold cavity. At the same time, the package is filled into the above-mentioned cavity under appropriate temperature rising conditions and filling pressure to seal and protect the wafer. Finally, the curing step is carried out to cure the package. M334463 However, when there are a plurality of wafers or other components on the above wafer carrier, this makes the above-mentioned object of the glue filling, because the needle material is uniform, when the package is guided from the end of the mold, it is very In the case where the mold is in the mold, the mold flow is not uniform, and the package is twisted to form a void in the package.

In order to solve this problem, it has been suggested that the effect of the US patent is still limited. Beyond the public ^ first ^1 = mold flow unevenness question 'has been proposed by the Republic of China patent, _5 遽 "array type substrate on the top of the kick brakes on this additional obstacles, and ^ fine and even average Then _上_动2cutting rhyme is too fast flowing, sealing: cutting is not enough (four) 'in the case of the surface fiber's use 'with laser cutting or can not provide an extremely flat table% >1334463 % face' When punching and cutting, the flatness is even worse. Underneath, the characteristics of the glass fiber are briefly explained, and it is explained why the laser can not provide a flat surface when the glass fiber is cut. The above glass fiber is mainly melted with glass. The main components of the fiber are: cerium oxide, aluminum oxide, calcium oxide. The glass fiber is divided into two categories: bismuth silicate glass fiber and borax silicate glass fiber. Features are: alkali-free electrical insulating glass (E glass), alkali glass (A glass), chemical glass (c glass), • New glass (S glass), diamond-containing glass (L glass), high elastic modulus glass (M glass) and low dielectric glass (D glass In the production of glass fiber, if the glass ball method is used, it is necessary to first make a glass ball according to the required formula, remove the defective product, and then send it into the disaster to smelt, so that the dissolved glass is from the bottom. A plurality of small holes flow out to form a tow. Thereafter, the tow is oiled and bundled and transported to a wire drawing drum of a speed of up to 2 GGG to 5 deg/min, and the drawing is called a glass draft. When the law is not, the yarn should be _ball, and the components can be directly injected into the kiln (10) when they are matched. After ___clear, pass through the small holes of dozens of drawing plates in the kiln. In the process, glass filaments are obtained. - Regardless of the method used to make the glass fiber, the glass fiber must contain the glass component, which causes the high temperature caused by laser cutting, when the laser is composed of glass. In the heat recording, somewhere, the surface fiber is received, and the thickness of the cut is naturally uneven. At the same time, the glass component is easy to be cut when the whole glass is cut. Provide a flat surface. 7 M334463 [New Content] The purpose of the miscellaneous supply _ seed mining _ vertical package packaging structure, two = the average dispersion of the people's miscellaneous county __ yuan, shouting the county body flat seal 7 structure. _ This way to seal the way, also minimize the package The need for "Knife Lai, the job is the premise, the lion (four) consequences. In addition, the creation of her independent paste package structure mainly contains the Γ carrier (including a plurality of carrier units), a plurality of sets on the wafer carrier =, the face mold is formed (mQlding) on the wafer (four) body on the top of each wafer. For the purpose of the production of the seal, the coffee chip for individual sculptures 曰 *, due to the glue The pressure is evenly distributed to each female sputum, and the female structure of the entire county is obtained. Formula: == point and spirit can be explained by the following new details and _ [Embodiment] County map-based creation _ stand-up package white work Dingxin diagram as shown in Figure 1A, in the creation of the creation; If the next society is (8) shop ig. The other ig has the above table I and is cut (10) on both surfaces to form an outer wiring layer (not drawn, 曰, so as to be electrically connected to the wafers 12a to 12b (for example, a flash memory matrix). In M334463 == vulgar (four) painful (5), 嶋 ι 〇 contains:: Wei carrier unit (5). And each body unit (10) defines a splicing area for mounting the wafers 12a~12b. As shown in FIG. 1B, a plurality of packages 16 are formed (f) ding for the wafer blanks. Specifically, the punching molds 12a to 12b are used as individual molds for inserting the glue (not filled into the mold cavity by the filling body, and the body 16 is individually packaged for each side 12). When the package is evenly dispersed into the adhesive pressure to each carrier unit (10), an overall flat block structure is obtained. In the structure shown in the parent _ =1 Β diagram, the area between the plurality of packages 16 is still batched 14 On the wafer carrier 1G, the area belonging to the dicing street U has __, and the thin layer of glue _ is connected to the plurality of packages 16. The thickness of the slab layer 16a is much smaller than that of the plurality of packages.

After the sealing, a plurality of carrier unit plates (10) (containing the wafer wafer carrier 1 (), respectively, are separated between each carrier unit and (10). It has been determined in advance that A has a staggered _way 14. In the opposite of the Μ Μ Μ 、, 10 Any circuit or electronic component, and can be hollowed out in advance to facilitate the subsequent cutting, but the wafer carrier (7) 9 M334463 in the relative position may have a semi-finished product on the upper surface and the lower surface. At the time, depending on the characteristics of the product (such as SD card), the laser and other means can be used to cut the desired shape along the cutting path 14 or to complete the cutting type with the part that has been previously hollowed out. In each of the above-mentioned "joining areas", Wei wafers may be stacked, and are not limited to single-layer crystals (four), such as 帛1Α~1Β崎, which are represented by the above-mentioned more complex body. The purpose of clearly defining the material of the present invention is to limit it. On the contrary, the purpose is to cover the various scales and ages of the scales of the application for the purpose of the application. Modes 1A to 1B are schematic views of a separate package for the creation of the present invention.
