For example, the grooves in ^ are preferably formed by the grooves provided in 1 to carry (at least the cattle ⑺) the cavity with which the packaging work # can be performed. Therefore, the mold is used as a capricorn for the cavity, so it is not possible (at all) that a mold part can be used for the function of the mold (at least in part because the product-oriented mold cavity is therefore two or two '): Cattle ... 〇7 Qiaowupin (at least partly) makes the product-oriented model, and r, J,, B, T j < parts (at least partly) are no longer, ▲ become process equipment The cost is greatly reduced. The process of replacing products during the manufacturing process is simplified. The important advantage is to arrange for reduction of _ ^^ according to the present invention. The package (package private) will be made white. Wrong * Chance will work, and the package may become "delammation" phenomenon, so that the mold in the delaminated eight-double mold assembly is empty and / or other problems occur. 工 J 禾 , Use according to the present invention The process steps of the carrier part turn into (at least part of) :: to be sealed = the chance of mistakes will be reduced. Sealing and also making the wrong package only need to make a Monday groove between the low-package processes (compared to the commission iridium + + ^ The person uses the mold many times in the traditional puller parts in the carrier, and Less clean packaging device parts + wicker slaps and eighty two workers), this point is more important, two important points. According to the present invention, the package of the electronic component is (at least the second part: r the carrier and the package outside After the two pairs of hardened = bearing = solidified in a relatively small amount, the carrier and its upper and lower cover 6 200529382 can be installed for subsequent operations, which has the additional advantage of being reduced. In addition, in making: * By%, the time element has been (at least partially) before the dressing agent 'the electron. This also results in another advantage, that is, when sealing ::::: 部;,' damaging the electronic component, and damaging the electron == The chance of the adjudicator's usually weak connection can be reduced. One of the cattle-bearing eight carriers is on the side: Tebi ::: ": In the example, the drive is on the side ... It is placed on the Cheng Gong ~ side. If a single groove can accept multiple electronic components, it is more advantageous to flatten the multiple electronic components with a single _ times =. In an extreme change, this method results in 》 = Time coverage. Carrying parts around the -1 beam under-gauge plane,: pieces. : Can be seeded as: Γ, where one or a very large number of electrons can be placed. In another variation, the carrier has a plurality of grooves (holes, the same): at least one electronic component, at least part of which can be placed in each groove It is located in the groove = the groove can be set to be located in the-carrier layer 'to form the complete structure of the carrier: two 1T imagine, for example, an upper layer with a concave and convex surface (p,) 1 and two electrical insulation materials in the composite carrier (substrate) These recesses ΓΓΓ are provided with the concave-convex surface during the manufacturing stage of the carrier (substrate), or it may be later (that is, the groove of the carrier is also manufactured): 7 can be provided with a mask that forms part of the carrier \ 'The groove is set in the mask. Such a mask, for example, can be made of a foll material of a carrier (for example, a label that can be attached to the carrier). Conversely, the mask can also be formed, at least in part, from a masking sheet connected to the carrier, a cardboard or plastic masking sheet. 7 Carrying parts, this month also includes the carrying parts as described above, the vertical grooves are at least partially filled with the encapsulant. Here, the recess of the package is fully cured, so that at least one part placed in the recess may be encapsulated without being divided into an encapsulant. The '70 pieces are at least partially, and ^ + pieces are at least partially sealed |, Great surface dry = ㈣ 子 components are completely covered by the encapsulant, = = child parts-part is not covered by the encapsulant into 4 Electricity acts as a sensor or valence detector, or.二 牛 “列 说 可 便 可以 贷 钱 #. 4 The heat generated by the piece is conducted to its environment. Two: Two ::: Changing. The bearing ...-Material channel selection-Narrowing the trough and recessing in the carrier Optional A-port (gate) for this material channel, which is set in the material channel and connected to the carrier. The material feed = the injection of the sealant can be passed through the narrow inlet and outlet ratio of the two-way channel provided on the carrier. Less known cause of the known technology: the injection channel of the product packaged according to the present invention (generally, it does not distinguish: not invented: "Invention, the product can remove its injection channel from the carrier together with the supplied encapsulant. Before that The sprue is a part of the mold, and it is: 'and needs frequent maintenance. Now that the sprue can be integrated with the carrier, use it once, and at least some of the shortcomings of the sprue no longer appear. In the embodiment, the groove provided in the carrier covers a sheet "to the carrier. The sheet material layer thus provides a protective layer for filling and mold parts connected to the mold cavity. The carrier may be provided with The channel can also cover the sheet material, so as to make the sealing in the channel Agent 200529382 cannot be adhered to the aforementioned bearing of the mold part. One of the present invention is electrically connected to one of the advantages. In the groove, the carrier is stacked with the carrier. A carrier layer can have a groove. It also forms a part before the stage above it. This kind of carrier has several contact positions to achieve the conduction of the electronic 7C part. This kind of carrier is superior to traditional carriers in that the conductive contact position is located in the The conductive contact positions of the carrier are partially protected (especially when mounted). According to the above, for at least one electronic component, the " Hai carrier may be provided with a plurality of grooves, and the grooves may be provided in The carrier is integrated with the carrier internally and / or the carrier becomes a part of the carrier. The recess is provided in the mask. In addition, the present invention provides a method for encapsulating and connecting electronic components of the carrier. · A) Provide a carrier with at least one electronic component placed adjacent to the carrier. ^ ^ ^ ^ ^ ^ ^ ^ U and connected with the side carrier,: B) in the carrier Recess Supply the sealant, and C) connect the encapsulant to the carrier and the electronic component. The meaning of the package here means that the electronic component is at least covered by the encapsulant. The encapsulant is usually used in process step B), which is to reach the concave yttrium of the carrier, and is cured in process step c). Putting the sealant I into the groove will make the main + splatter ) ... "5's composition) Leakage (overflow and squirt 'towel field lowering' After all, the groove can be set as a groove that only opens on the top side, so that you do n’t want the unintentional private W / see-through appearance The overflow / leakage of the encapsulant to the next month will not happen. Except for the advantages of the carrier according to the present invention, the sealing force required for the device to be encapsulated at f ^ ( closing 〇rce) has become the same. The encapsulant can be theoretically introduced (introduced) 9 200529382 This groove does not need to be put in / dusty during sealing. The encapsulant that has been cured in the groove can be contacted with a part that affects the shape of the encapsulant when it is cured, so that the part is placed in the bearing #, where the electronic component is sealed. The grooves inside are most obviously the use of substantially flat mold parts. ί? Use a relative I ”method-in a better application, in the process step C), the carrier = the bracket part controlling it is in a stationary state = a substantially flat thin uncle 7 and moving. This I can do it together; ^ The plate can be replaced by at least one of its molds with empty parts relative to the bracket parts. These pairs: = the mold parts are changed, this method can be modified by using / Easy to achieve, no problem due to the implementation of white sigma packaging equipment. / ,,, and: This method also works. Carrying out different ways to implement the packaging operation-type bracket disaster parts II / 蛉, hunting control load One of the parts can be moved and leveled at the same time: ^ and one of the mold parts that also controls the carrier is also owed ^ the row W of the carrier is moved forward. The carrier and the mold are assembled Γ =: the-part of the endless conveyor belt Servings. So the package can be in a lot of singles. Compared with the existing packaging equipment, the device has a simpler arrangement of the electronic components connected to the carrier, and / or can supply the encapsulant to the fixed ΓΓ grooves at the same time. It is also possible to further increase the opening in a carrier The efficiency of the above electronic component packaging. The above 2 I provides further a method to separate the sub-element fixed to a carrier from the carrier, which includes the following process steps: x) 10 200529382 Provide-the carrier has at least part of the filling solidified And an electronic component is at least partly broken into a groove, and a mouth knife is placed in the groove, and a part of the carrier for holding the electronic component is sealed. Therefore, it is not necessary to remove the device constituting the groove after the encapsulant is thrown into the carrier = the remaining part, for example, after the groove, it is unexpected and / or a mask. The at least layer,-sheet material ... that is, the process technology enclosed by the cured encapsulant is removed from the carrier 7 directly hunted by non-cutting, or jealous— \ diamond cutting, (laser) ^ For off-technology. The pudu covering the groove can also be separated during this separation process. [Embodiment] Figure 1A shows the display-the bearing i, the sub-element 3 on it is placed in the groove 2 and the second element is 2 out, the electric h T 〇 another is shown in Figure 1B The way in which the bearing member 4 is applied in the middle of the month shows that the two grooves 5 in the halberd owl 4 are different from the case of the bearing member 1A in FIG. This material layer 6 may be composed of, for example, a material, cardboard, or any other material.
