Furthermore, the accompanying drawings of this invention are for simple illustrative purposes only and are not depictions of actual dimensions; this is stated in advance. The following embodiments will further describe the relevant technical content of this invention in detail, but the disclosed content is not intended to limit the scope of protection of this invention.
[0027] It should be understood that while terms such as "first," "second," and "third" may be used in this document to describe various components or features, these components or features should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one feature from another. Furthermore, the term "or" as used in this document should, as appropriate, include any combination of one or more related listed items.
[0028] [Example 1] Please see Figures 1 to 15 As shown, this is an embodiment of the present invention. Figures 1 to 3 As shown, this embodiment discloses an electronic device 1000, which includes a chip package structure 100 and a circuit board 200 for soldering onto the circuit board 200. It should be noted that although the chip package structure 100 is described in this embodiment as being used in conjunction with the circuit board 200, the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the chip package structure 100 may also be used independently (e.g., for sale) or in conjunction with other components, depending on actual needs.
[0029] In this embodiment, the chip packaging structure 100 includes a mounting plate 1, a matching component 2 mounted on the mounting plate 1, a package body 3 formed on the mounting plate 1, and an electronic chip 4 embedded within the mounting plate 1. The mounting plate 1 has an internal antenna function, and the subsequent descriptions of this embodiment primarily focus on the partial structure of the mounting plate 1 related to the antenna function. Other structures of the mounting plate 1 related to the electronic chip 4 can be adjusted and varied according to actual needs, and will not be elaborated here. Furthermore, for ease of explanation, in this embodiment, the mounting plate 1 is defined with a thickness direction T, a first direction D1, and a second direction D2 that are perpendicular to each other.
[0030] like Figures 3 to 5As shown, the packaging substrate 1 in this embodiment includes an insulating layer 11, an outer metal layer 12 embedded within the insulating layer 11, and an inner metal layer 13 embedded within the insulating layer 11. The insulating layer 11 has an inner surface 111 and an outer surface 112 located on opposite sides. The insulating layer 11 may be composed of multiple layers of insulating material stacked together (the attached figure shows a single-layer structure pressed together) and two solder resist layers formed on both sides of the multiple layers of insulating material. The thickness of each insulating layer may be between 20 micrometers (μm) and 100 micrometers, but is not limited thereto.
[0031] Furthermore, in this embodiment, the thicknesses of the outer metal layer 12 and the inner metal layer 13 are each between 10 micrometers and 30 micrometers, and the outer metal layer 12 and the inner metal layer 13 are spaced apart from each other along the thickness direction T. The outer metal layer 12 is adjacent to the outer surface 112, while the inner metal layer 13 is adjacent to the inner surface 111.
[0032] More specifically, the outer metal layer 12 includes an antenna layout segment 121 and a plurality of frequency adjustment pads 122 disposed corresponding to the antenna layout segment 121. The antenna layout segment 121 has a slotted antenna 1212 recessed from one of its edges 1211 along the first direction D1, and the slotted antenna 1212 has a slot 1212a located at the edge 1211, a bottom wall 1212b away from the slot 1212a, and two sidewalls 1212c (vertically) connected to the bottom wall 1212b.
[0033] In this embodiment, the slot antenna 1212 has a slot depth L1212 along the first direction D1 and a slot width W1212 along the second direction D2. In other words, the slot depth L1212 is the distance between the slot opening 1212a and the bottom wall 1212b, preferably between 6.5 mm and 7 mm, while the slot width W1212 is the distance between the two side walls 1212c, preferably between 1 mm and 1.5 mm. However, the invention is not limited to these values.
[0034] Furthermore, the antenna layout segment 121 has a plurality of slotted adjustment pads 1213 exposed on the outer surface 112, and the plurality of slotted adjustment pads 1213 are adjacent to the bottom wall 1212b and are respectively located on opposite sides of the slotted antenna 1212. Furthermore, the plurality of slotted adjustment pads 1213 are spaced apart from the bottom wall 1212b along the first direction D1 by a maximum spacing distance L1, which is preferably within 30% of the slot depth L1212, but the invention is not limited thereto.
[0035] In other words, the plurality of grooved adjusting pads 1213 are respectively adjacent to but do not touch the two sidewalls 1212c, and the number of grooved adjusting pads 1213 adjacent to each sidewall 1212c is described as two in this embodiment, but it can be adjusted and varied according to actual needs. For example, such as Figure 6 As shown, the number of groove-shaped adjusting pads 1213 adjacent to any one of the sidewalls 1212c can be a single one.
[0036] Furthermore, the antenna layout segment 121 forms a plurality of configuration holes 1214 located on opposite sides of the slot antenna 1212. The plurality of configuration holes 1214 are recessed into the two sidewalls 1212c of the slot antenna 1212 (that is, each configuration hole 1214 is connected to the slot antenna 1212 in the second direction D2).
[0037] Furthermore, in this embodiment, the number of the plurality of configuration holes 1214 is described as two, and the two configuration holes 1214 are arranged facing each other along the second direction D2, but the present invention is not limited thereto. For example, such as Figure 7 As shown, the plurality of configuration holes 1214 may be adjacent to but not touching the two sidewalls 1212c (that is, each configuration hole 1214 is not connected to the slot antenna 1212 in the second direction D2). Alternatively, in other embodiments of the invention not illustrated, the plurality of configuration holes 1214 may be staggered.
[0038] The plurality of frequency adjustment pads 122 are respectively located within the plurality of configuration holes 1214 and do not contact the antenna layout segment 121, and the plurality of frequency adjustment pads 122 are exposed on the outer surface 112. In this embodiment, two frequency adjustment pads 122 are disposed within each configuration hole 1214, which are adjacent to each other and spaced apart from each other. Each frequency adjustment pad 122 does not protrude from the corresponding sidewall 1212c of the slot antenna 1212, and each frequency adjustment pad 122 is partially exposed on the outer surface 112, but is not limited thereto.
[0039] Furthermore, the plurality of frequency adjustment pads 122 are respectively located on opposite sides of the slot antenna 1212, and the plurality of frequency adjustment pads 122 are further away from the bottom wall 1212b than the plurality of slot adjustment pads 1213. In this embodiment, the plurality of frequency adjustment pads 122 and the plurality of slot adjustment pads 1213 are arranged in two columns approximately along the two side walls 1212c.
[0040] Furthermore, the plurality of frequency adjustment pads 122 are spaced apart by a configuration distance L2 along the first direction D1 from the slot 1212a (or the edge 1211), which is at least 30% of the slot depth L1212.
[0041] Furthermore, the outer metal layer 12 also has a plurality of grounding pads 1215 exposed on the outer surface 112, which are located (or surround) the outside of the antenna layout segment 121 to provide a complete grounding loop. In this embodiment, the plurality of grounding pads 1215 are generally U-shaped and surround the outside of the plurality of frequency adjustment pads 122 and the plurality of slotted adjustment pads 1213, and the number of the plurality of grounding pads 1215 is greater than the sum of the number of the plurality of frequency adjustment pads 122 and the plurality of slotted adjustment pads 1213, but the invention is not limited thereto.
[0042] The slot antenna 1212 defines an extension space along the thickness direction T, and the inner metal layer 13 includes a feed line 131 spanning the extension space, a metal pad 132 located on one side of the extension space, and two coupling regions 133 located on opposite sides of the extension space. The feed line 131 is adjacent to the slot 1212a of the slot antenna 1212, the metal pad 132 can be used for grounding, and the metal pad 132 is spaced apart and adjacent to one end of the feed line 131.
[0043] More specifically, in this embodiment, the feed line 131 includes a spanning section 1311, a first extension section 1312 connected to one end of the spanning section 1311, and a second extension section 1313 connected to the other end of the spanning section 1311. The spanning section 1311 is an elongated structure parallel to the second direction D2 and adjacent to the slot 1212a (or the edge 1211). The first extension section 1312 extends from the spanning section 1311 in a direction away from the slot 1212a, and has a length between 0.6 mm and 1 mm in the first direction D1 and a width between 0.4 mm and 0.5 mm in the second direction D2. Furthermore, the second extension 1313 is formed by extending from the transverse section 1311 in a direction away from the slot 1212a, the metal pad 132 is adjacent to and spaced from the second extension 1313, and the second extension 1313 and the metal pad 132 face the first extension 1312 along the second direction D2.
[0044] Two coupling regions 133 are electrically coupled to the antenna layout segment 121, and the two coupling regions 133 are respectively spaced between the first extension segment 1312 of the feed line 131 and the metal pad 132. The two coupling regions 133 respectively shield the plurality of configuration holes 1214 and the plurality of frequency adjustment pads 122 along the thickness direction T. It should be further noted that, in this embodiment, the packaging substrate 1 preferably does not have other metal layers disposed between the outer metal layer 12 and the inner metal layer 13, thus providing coupling for the plurality of frequency adjustment pads 122 through the two coupling regions 133, but the present invention is not limited thereto.
[0045] The matching component 2 connects the feed line 131 and the metal pad 132. In this embodiment, the matching component 2 is described as a capacitor with a capacitance value between 2.5 pF and 4 pF, but the invention is not limited thereto. For example, in other embodiments not shown in the invention, the matching component 2 can be replaced by other components or omitted depending on actual needs.
[0046] The electronic chip 4 is mounted on the packaging substrate 1 and located on the inner surface 111 of the insulating layer 11, and the electronic chip 4 can be electrically coupled to the feed line 131 of the inner metal layer 13 through the packaging substrate 1. Furthermore, the package 3 is formed on the inner surface 111 of the insulating layer 11 so that the electronic chip 4 and the mating component 2 are embedded within the package 3. In this embodiment, the circumferential edge of the package 3 is flush with the outer edge of the packaging substrate 1.
[0047] It should be further noted that although the packaging substrate 1 is described in this embodiment as being used in conjunction with the package 3 and the electronic chip 4, the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the packaging substrate 1 may also be used alone (e.g., for sale) or in conjunction with other components, depending on actual needs.
[0048] The above describes the construction of the packaging substrate 1 in this embodiment, so that the slot antenna 1212 of the chip package structure 100 has an initial center frequency. The following describes the structural pairing between the packaging substrate 1 and the circuit board 200, and the electronic device 1000 defines a default center frequency. The chip package structure 100 is soldered and fixed to the circuit board 200 using the packaging substrate 1, so that the electronic chip 4 is electrically coupled to the circuit board 200 through the packaging substrate 1.
[0049] Furthermore, the circuit board 200 includes a substrate 203 and a ground layer 201 formed on the substrate 203 and electrically coupled to a plurality of ground pads 1215, and the ground layer 201 forms a clearance hole 2011. Moreover, the circuit board 200 includes at least one adjustment line 202 formed on the substrate 203, which is located within the clearance hole 2011 and does not contact the ground layer 201. The plurality of ground pads 1215 are located (or surround) the outside of the clearance hole 2011, and the slot antenna 1212 is orthographically projected along the thickness direction T onto a projection area formed by the ground layer 201, which is located within the clearance hole 2011.
[0050] As described above, when the chip package structure 100 is soldered to the circuit board 200, at least one adjustment line 202 of the circuit board 200 spans the slot antenna 1212 and connects to two slot adjustment pads 1213 or two frequency adjustment pads 122. Accordingly, after the chip package structure 100 has been manufactured, it can compensate for possible frequency shifts in the chip package structure 100 (or the package carrier 1) through at least one adjustment line 202 of the circuit board 200, thereby effectively providing greater antenna design flexibility and significantly reducing antenna design development time.
[0051] In other words, the chip package structure 100 in this embodiment provides a calibrated frequency adjustment function, and the chip package structure 100 is connected to at least one adjustment line 202 to adjust the initial center frequency toward the default center frequency. It should be further noted that the circuit board 200 compensates for or eliminates the frequency deviation between the initial center frequency and the default center frequency of the chip package structure 100 by forming at least one adjustment line 202. That is, if there is no frequency deviation between the initial center frequency and the default center frequency, the circuit board 200 does not need to form the adjustment line 202. Accordingly, the circuit board 200 selectively provides at least one adjustment line 202 in this embodiment.
[0052] More specifically, the number of at least one adjustment line 202 on the circuit board 200 may be zero; or, depending on the situation, the circuit board 200 may use at least one adjustment line 202 to connect to two slotted adjustment pads 1213 (e.g.: Figure 9 and Figure 10 ) or two of the aforementioned frequency adjustment pads 122 (e.g.: Figure 8 and Figure 11This allows for frequency adjustment. In other words, both the frequency adjustment pad 122 and the slotted adjustment pad 1213 in this embodiment can provide frequency adjustment functionality through at least one adjustment line 202.
[0053] Furthermore, the radiation efficiency charts obtained after simulation experiments (e.g.: Figure 12 ) and reflection loss charts (e.g.: Figure 13 In the above, curve C0 corresponds to the electronic device 1000's circuit board 200 having no adjustment lines 202, and curve C1 corresponds to... Figure 9 The electronic device 1000 shown, curve C2 corresponds to Figure 10 The electronic device 1000 shown, curve C3 corresponds to Figure 8 The electronic device 1000 shown, curve C4 corresponds to Figure 11 The electronic device 1000 is shown. It can be seen that the electronic device 1000 can indeed effectively adjust the initial center frequency of the chip package structure 100 by means of the chip package structure 100 and at least one adjustment line 202, and its frequency adjustment range can reach at least 150MHz, thereby conforming to various wireless communication protocols (such as Bluetooth).
[0054] Furthermore, the number of at least one adjustment line 202 on the circuit board 200 can be adjusted to multiple (e.g., two) according to actual needs; for example, such as Figure 14 As shown, one of the adjustment lines 202 connects to two of the slotted adjustment pads 1213 and is defined as a slotted adjustment line 202a, while the other adjustment line 202 connects to two of the frequency adjustment pads 122 and is defined as a frequency adjustment line 202b.
[0055] To better understand this embodiment, the following further describes the plurality of slot adjustment pads 1213 and the plurality of frequency adjustment pads 122. In this embodiment, the plurality of slot adjustment pads 1213 include a plurality of first slot adjustment pads 1213-1 located on one side of the slot antenna 1212, and a plurality of second slot adjustment pads 1213-2 located on the other side of the slot antenna 1212. Each first slot adjustment pad 1213-1 can be connected to any one of the second slot adjustment pads 1213-2 through the slot adjustment line 202a, so that the bottom edge of the slot antenna 1212 can be changed from the bottom wall 1212b to the slot adjustment line 202a, thereby adjusting the initial center frequency.
[0056] Furthermore, the plurality of frequency adjustment pads 122 include a plurality of first frequency adjustment pads 122-1 located on one side of the slot antenna 1212, and a plurality of second frequency adjustment pads 122-2 located on the other side of the slot antenna 1212. Each of the first frequency adjustment pads 122-1 can be connected to any one of the second frequency adjustment pads 122-2 via the frequency adjustment line 202b, thereby forming a capacitive effect to change the initial center frequency.
[0057] It should be further noted that each of the first slotted adjustment pads 1213-1 faces a second slotted adjustment pad 1213-2 along the second direction D2, and each of the first frequency adjustment pads 122-1 faces a second frequency adjustment pad 122-2 along the second direction D2. Preferably, both the slotted adjustment line 202a and the frequency adjustment line 202b are parallel to the second direction D2, but this invention is not limited thereto. For example, such as... Figure 15 As shown, the slot-shaped adjustment line 202a and the frequency adjustment line 202b can also be non-parallel to the second direction D2.
[0058] [Example 2] Please see Figures 16 to 18 As shown, this is Embodiment Two of the present invention. Since this embodiment is similar to Embodiment One described above, the similarities between the two embodiments will not be repeated. The differences between this embodiment and Embodiment One are roughly explained as follows: In this embodiment, the inner metal layer 13 of the packaging substrate 1 does not have two coupling regions 133, and the packaging substrate 1 further includes at least one amplification metal layer 14 embedded within the insulating layer 11, located between the inner metal layer 13 and the outer metal layer 12. At least one amplification metal layer 14 shields a plurality of configuration holes 1214 and a plurality of frequency adjustment pads 122 along the thickness direction T.
[0059] Furthermore, at least one of the amplification metal layers 14 forms a coupling slot 141, the inner wall of which at least 80% overlaps along the thickness direction T with the bottom wall 1212b and the two side walls 1212c of the slot antenna 1212. It should be noted that the number of at least one amplification metal layer 14 is described as two in this embodiment, but the invention is not limited thereto.
[0060] [Technical Effects of the Embodiments of the Invention] In summary, the electronic device, chip packaging structure and its packaging substrate disclosed in the embodiments of the present invention, after completion of manufacturing, can compensate for the frequency offset that may be generated by the chip packaging structure (or the packaging substrate) through at least one adjustment line of the circuit board, thereby effectively providing higher antenna design flexibility and significantly reducing the antenna design development time.
[0061] Furthermore, the packaging substrate disclosed in the embodiments of the present invention can effectively achieve miniaturization through structural matching (such as the slot antenna of the outer metal layer matching the inner metal layer and the matching component), thereby enabling the chip packaging structure to effectively integrate the antenna function inside, thereby saving space and reducing the time for antenna design and shortening the development process.
