[0030] Figure 1 This is a method for manufacturing a flexible electronic packaging device according to an embodiment of the present invention. For example... Figure 1 As shown, in step S110, the allowable bending radius (R) of the flexible electronic packaging device is determined. tol _ Sip Flexible electronic packaging devices are flexible, but they can still be damaged if the stress caused by bending is too great. Therefore, the bending tolerance of flexible electronic packaging devices is a necessary consideration.
[0031] In this embodiment, the flexible electronic packaging device is intended to be disposed on an application carrier for use. In other words, the application carrier referred to herein is the object on which the flexible electronic packaging device is intended to be disposed. For example, the application carrier may be a wearable item or other three-dimensional object. In order to determine the proper operation of the flexible electronic packaging device after it is disposed on the application carrier, the characteristics of the application carrier can be used as parameters to be considered when manufacturing the flexible electronic packaging device. Therefore, in step S120, the minimum surface radius of curvature (R) of a selected portion of the application carrier is determined. min _ C In some embodiments, when the application carrier itself is a three-dimensional object, step 120 may include scanning a selected portion of the application carrier where a flexible electronic packaging device is to be disposed, to obtain the surface radii of curvature of individual surfaces in the selected portion, and selecting the smallest of these surface radii of curvature as the minimum surface radius of curvature (R) of the selected portion. min _ C In other embodiments, when the application carrier itself is fabric or a wearable item, the application carrier can be first positioned in a worn state, and then individual surfaces of a selected portion of the application carrier in the worn state can be scanned. The smallest surface radius of curvature (R) among the scanned individual surfaces is selected as the minimum surface radius of curvature (R) of the selected portion. min _ C For example, when the application carrier is clothing covering the human torso, such as a T-shirt, shirt, or athletic leggings, the application carrier can first be worn on a mannequin, and then a selected portion of the application carrier can be scanned to obtain the minimum surface radius of curvature (R) of the selected portion. min _ C ).
[0032] Next, step S130 can be performed to determine the permissible bending radius (R) of the flexible electronic packaging device. tol _ Sip Is it less than or equal to the minimum surface radius of curvature (R) of the selected portion of the application carrier? min _ C The relationship between the allowable bending radius (R) of flexible electronic packaging devices. tol _ Sip The radius of curvature of the selected portion of the application carrier is less than the minimum surface radius of curvature (R). min _ C This indicates that the flexural stress experienced by the flexible electronic package when it is mounted on the surface of the selected portion is less than the tolerance of the flexible electronic package itself. In other words, the flexible electronic package is less likely to be damaged due to unevenness of the surface of the selected portion when mounted on the selected portion of the application carrier. Therefore, step S130 determines the allowable bending radius (R) of the flexible electronic package. tol _ Sip The radius of curvature of the selected portion of the application carrier is less than the minimum surface radius of curvature (R). min _ C After that, step S140 can be performed to place the flexible electronic packaging device on the selected portion. In this way, even if the application carrier with the flexible electronic packaging device is bent during use or the application carrier itself has a curved surface, the flexible electronic packaging device is not easily damaged, thereby achieving a higher manufacturing yield and a better service life.
[0033] Additionally, step S130 determines no, that is, the allowable bending radius (R) of the flexible electronic packaging device. tol _ Sip The radius of curvature of the selected portion of the application carrier is greater than the minimum surface radius of curvature (R). min _ C This indicates that the surface curvature of a selected portion of the application carrier may be equal to or greater than the tolerance of the flexible electronic packaging device. In this case, step S150 can be performed to redesign the flexible electronic packaging device. In some embodiments, the method for redesigning the flexible electronic packaging device includes... Figure 2 The method shown enables the redesigned flexible electronic package to meet the allowable bending radius (R). tol _ Sip The minimum surface radius of curvature (R) of the selected portion is less than or equal to that of the selected portion. min _ C The redesigned flexible electronic package device can be accessed via… Figure 1The process continues through steps S110 to S130 until step S140 is reached to place the flexible electronic packaging device in the selected portion. In this way, even if the application carrier with the flexible electronic packaging device is bent during use or has a curved surface, the flexible electronic packaging device is less likely to be damaged, thus achieving higher manufacturing yield and better service life.
[0034] Figure 2 The illustration schematically depicts a method for determining the minimum permissible bending radius of a flexible electronic package according to some embodiments. Generally, a flexible electronic package may include multiple components, and the material properties of each component, its placement, and the stacking relationship between the components all affect the flexibility of the package's tolerance to flexural stress. Therefore, a method may be employed... Figure 2 The method for determining the minimum allowable bending radius (R) of a flexible electronic package device tol _ Sip Specifically, in step S112, an initial bending radius (R) is set. i ), and calculate the bending stress (S) of each component in the flexible electronic packaging device. max Furthermore, in step S114, failure criteria for each component are established to determine the maximum allowable stress value (S) for each component. limit +FS). Here, S limit For example, the yield strength or ultimate strength of an individual component, while FS is, for example, the factor of safety. In some embodiments, the factor of safety can be defined as S. limit × Safety percentage, where the safety percentage can be set to greater than 0% and up to a maximum of 100%. Taking a safety percentage of 100% as an example, the maximum allowable stress value for each component can be approximately S. limit +S limit ×100%, which is twice the yield strength of an individual component. Taking a safety percentage of 50% as an example, the maximum allowable stress value of each component can be approximately S. limit +S limit ×50%, which is 1.5 times the yield strength of an individual component.
[0035] In step S116, the bending stress value (S) of each component can be determined. max Are all values less than or equal to the maximum allowable stress value? For each component at its initial bending radius (R)... i Bending stress value (S) under ) max If the stress value is less than the maximum allowable stress value, it means that the component is at the initial bending radius (R). iThe stress experienced by all components under the initial bending radius (R) has not yet reached its tolerable level. At this point, the component is not easily damaged by bending. Therefore, all components of the flexible electronic packaging device are within the initial bending radius (R). i All of them conform to the bending stress value (S) max When the initial bending radius (R) is less than or equal to the maximum allowable stress value, i.e., when step S116 determines it to be true, step S118 can be performed to determine the initial bending radius (R). i The allowable bending radius (R) of the flexible electronic packaging device is... tol _ SiP The permissible bending radius (R) is determined by this. tol _ SiP ) can be applied to Figure 1 In step S110. Figure 1 In step S130, if the minimum allowable bending radius (R) of the determined flexible electronic package device is... tol _ SiP ) less than or equal to the minimum surface radius of curvature (R) min _ C This allows the flexible electronic packaging device to be placed in a selected portion of the application carrier. Figure 1 In step S130, if the determined minimum allowable bending radius (R) tol _ SiP ) greater than the minimum surface radius of curvature (R) min _ C This requires changing the design of the flexible electronic packaging device and redesigning it according to... Figure 2 The method for obtaining the minimum surface curvature radius (R) after the updated design min _ C ), then proceed Figure 1 The judgment process.
[0036] Additionally, if a component has an initial bending radius (R) i The bending stress value S under ) max If the initial bending radius (R) is greater than the maximum allowable stress value, which means step S116 is incorrect, it indicates that the initial bending radius (R) is greater than the maximum allowable stress value. i The state of [something] may cause certain components to experience stresses exceeding their permissible limits, making them prone to damage due to bending. Therefore, it was determined that some components [have] initial bending radius (R [radius]). i Bending stress value (S) under ) max If the stress value is greater than the maximum allowable stress value, proceed to step S112 and reset another bending radius (R). i The new bending radius can be different from the previously set initial bending radius (R). i Larger values are needed to find the bending stress value (S). maxThe condition is that the stress is less than the maximum allowable stress value.
[0037] In some embodiments, the initial bending radius (Ri) in step S112 can be based on Figure 1 The minimum surface radius of curvature (R) of the selected part of the application carrier obtained in step S120 min _ C This can be configured using [a specific method]. For example, the location where the flexible electronic packaged device is intended to be placed on the application carrier is predetermined. In this case, [a specific method] can be used. Figure 1 Step S120 involves scanning a selected portion of the application carrier to obtain the minimum surface curvature radius (R) of that selected portion. min _ C Then, based on the minimum surface radius of curvature (R) of the selected portion of the application carrier... min _ C The method for determining the electronic packaging device suitable for flexible mounting on a selected portion of the carrier includes: setting an initial bending radius (Ri) according to step S112, such that the set initial bending radius (Ri) is smaller than the minimum surface curvature radius (R) of the selected portion of the carrier surface. min _ C The bending stress value of each component in the flexible electronic packaging device is calculated at the initial bending radius (Ri). Next, as described in step S114, the maximum allowable stress value of each component is determined, and a judgment is made according to the steps in step S116. Figure 2 Step S116 determines the individual bending stress values (S) of all components. max If all values are less than or equal to the individual maximum allowable stress values, then the electronic package is deemed suitable for mounting on a selected portion of the carrier. Since the initial bending radius (Ri) is set to be less than the minimum surface curvature radius (R0),... min _ C After step S116 is passed, the process proceeds to step S140. Therefore, this flexible electronic packaging device can be placed on a selected portion of the application carrier.
[0038] Figure 3 This illustration demonstrates how to determine the bending stress values of each component. In other words, Figure 3 The specific manner in which step S112 is described is used, but it is not limited to this. Figure 3In this embodiment, the flexible electronic packaging device 200 is, for example, in a bent state and has a neutral surface 202, where the neutral surface 202 is the surface formed by the points where the bending stress experienced in the bent state is zero. Furthermore, in this embodiment, the radius of curvature ρ is defined as the distance from the center of curvature O to the neutral surface 202. The component 210 in the flexible electronic packaging device 200 is separated from the neutral surface 202 by a distance d in the Y direction, and the neutral surface 202 is located between the center of curvature O and the component 210. Therefore, the bending stress value σ experienced by the component 210 in the X direction is... x It can be derived from the formula: σ x = -E×d / ρ, where E is the Young's coefficient of component 210. It can be seen that the bending stress on component 210 is directly proportional to the distance d from the neutral surface 202 and the Young's coefficient E, and inversely proportional to the radius of curvature ρ.

Specifically, component 310 is, for example, an electronic component, including, for example, an integrated circuit chip, a passive component, a sensing component, etc. Component 320 is, for example, a first flexible substrate, which is, for example, a substrate with flexible properties and sufficient support to stably support the electronic component 310. Component 330 is, for example, a second flexible substrate, used to support the first flexible substrate, and the size of the second flexible substrate may be larger than that of the first flexible substrate. Component 310 may be joined to component 320, and component 320 may be joined to component 330 to form a stack structure in which the first flexible substrate is located between the second flexible substrate and the electronic component. Furthermore, component 310 may be electrically connected to component 320, and component 320 may be electrically connected to component 330. That is, the electronic component, the first flexible substrate, and the second flexible substrate may be electrically connected to each other.

In some embodiments, component 320 may have conductive vias, and component 360 may be a conductive pad disposed on the surface of component 320. Component 340 may be electrically connected to component 360 on the opposite side via the conductive vias in component 320. Component 370 may be a conductive pad disposed on component 330, and component 370 and component 360 face each other. Component 380 may be a conductive particle bonding member, disposed between component 360 and component 370, to electrically connect the structure of component 360 to component 370. Thus, component 310 can be electrically connected to the conductive lines in component 330 through the conductive through-holes of components 340 and 320, as well as components 360, 380, and 370. Component 380 can be anisotropic conductive adhesive, but is not limited thereto.

The material of the sensing electrode includes biocompatible materials. When the flexible electronic packaging device 400 is disposed on the surface of an application carrier, component 390 can face the user and is positioned to contact the user. For example, when the application carrier is a wearable item, the flexible electronic packaging device 400 is positioned on the wearable item with component 390 located closer to the wearer.

Component 352 can be disposed between component 312 and component 320 and used to fill the gap between components 342. In some embodiments, components 310 and 312 are also electronic assemblies, but can be used for different functional operations. Component 342 and 340 are also conductive connectors and may have the same or different structures and / or materials. Component 352 and 350 are both fillers, but may have the same or different materials.

Thus, although the selected parts 710 and 720 of the application carrier 700 are non-planar in use and / or wear conditions, the flexible electronic packaging device 600 is not easily damaged by bending stress. Therefore, the flexible electronic packaging device 600 can have an ideal service life.
