These terms are mainly used to distinguish one element from another element, or one signal from another signal. In addition, the term "or" used herein should, depending on the actual situation, may include any one or a combination of more of the associated listed items.
[0034] First Embodiment
[0035] Please refer to Figures 1 to 5 , which are respectively the first usage state schematic diagram, the second usage state schematic diagram, the third usage state schematic diagram, the first structure schematic diagram, the second structure schematic diagram, the third structure schematic diagram, the functional block diagram of the laser repair device of the first embodiment of the present application, and the flow schematic diagram of the laser repair method. As shown in the above diagrams, the first embodiment of the present application provides a laser repair device Z, which may include a carrier module 1, a filler supply module 2, and a laser projection module 3.
[0036] Cooperating with Figures 1 to 6 As shown, the carrier module 1 of the present application can be configured to carry at least one object to be repaired B. Among them, at least one object to be repaired B may have a first conductive element B1 and a second conductive element B2, and the first conductive element B1 and the second conductive element B2 are not connected to each other. For example, the carrier module 1 can be a biaxial (X-axis, Y-axis) or multi-axial (X-axis, Y-axis, Z-axis, but not limited thereto) mobile stage device. The object to be repaired B can be an electronic component, such as a flexible printed circuit (FPC), but not limited thereto; the first conductive element B1 and the second conductive element B2 can be metal circuits or metal patterns provided on the object to be repaired B; and, the object to be repaired B may also have a polymer material layer B3, such as: a polyimide (PI) layer, but not limited thereto. The object to be repaired B can be carried on the upper surface of the carrier module 1.
[0037] Next, cooperating withFigure 1 As shown, the replenishment supply module 2 of the present application can be adjacent to the carrier module 1. The replenishment supply module 2 can be configured to provide a repair liquid R between the first conductive element B1 and the second conductive element B2. The repair liquid R includes a plurality of replenishment parts R1. For example, the replenishment supply module 2 can be a liquid supply device and can store the repair liquid R. Among them, the repair liquid R includes a plurality of replenishment parts R1 and a solution R2. The replenishment parts R1 can be silver nanoparticles (AgNanoparticle), and the solution R2 can be a solvent. The plurality of replenishment parts R1 and the solution R2 can be mixed to form the repair liquid R.
[0038] Next, in cooperation with Figures 2 to 6 As shown, the laser projection module 3 of the present application can be adjacent to the carrier module 1. The laser projection module 3 can be configured to project at least one pulsed laser beam L onto the plurality of replenishment parts R1 to sinter the plurality of replenishment parts R1 and drive the plurality of replenishment parts R1 to form a conductive block C. For example, the laser projection module 3 can be a laser projection device. The laser projection module 3 can project at least one pulsed laser beam L. The pulse width of the pulsed laser beam L can be in the femtosecond order of magnitude (10 -15 seconds), the pulse width of the pulsed laser beam L can be less than 500 fs, the pulse repetition frequency of the pulsed laser beam L can be greater than 1 MHz, the wavelength of the pulsed laser beam L can be between 980 - 1080 nm or 465 - 5650 nm, and the spot size of the pulsed laser beam L can be between 10 - 100 μm.
[0039] Therefore, in cooperation with Figures 1 to 6 As shown, when the laser repair device Z of the present application is in use, at least one object to be repaired B can be first placed on the carrier module 1. Then, the replenishment supply module 2 can be controlled to drive the replenishment supply module 2 to drip the repair liquid R between the first conductive element B1 and the second conductive element B2 by using the supply head 200, and the repair liquid R contacts the first conductive element B1 and the second conductive element B2.
[0040] Next, the object to be repaired B is left standing to allow the solution R2 in the repair liquid R to evaporate and volatilize, leaving only the plurality of replenishment parts R1 on the object to be repaired B. Then, a pulsed laser beam L with a pulse width in the femtosecond order of magnitude (10 -15 seconds) can be projected onto the plurality of replenishment parts R1 on the object to be repaired B by controlling the laser projection module 3 to sinter the plurality of replenishment parts R1, and the plurality of replenishment parts R1 are sintered into a single conductive block C. The conductive block C can electrically connect the first conductive element B1 and the second conductive element B2.
[0041] Thus, through the above technical solution, the laser repair device Z of the present application uses the filler supply module 2 to provide the repair liquid R containing silver nanoparticles onto the local surface of the object B to be repaired, and projects a pulsed laser beam L with a pulse width in the femtosecond order of magnitude (10 -15 seconds) onto the silver nanoparticles through the laser projection module 3, so that the silver nanoparticles are sintered into a conductive block C, and then the first conductive element B1 and the second conductive element B2 are electrically connected by using the conductive block C to achieve the purpose and effect of conducting electricity in a local area. Moreover, since the pulsed laser beam L in the femtosecond order of magnitude (10 -15 seconds) has the effect of generating a very small heat affected zone, therefore, in the above manner, the pulsed laser beam L will not affect the polymer material or polymer material layer B3 adjacent to the first conductive element B1 and the second conductive element B2, and deformation of the polymer material can be avoided; furthermore, the pulsed laser beam L will not affect the circuit structures of the first conductive element B1, the second conductive element B2 and the object B to be repaired, and damage to the circuit structures of the first conductive element B1, the second conductive element B2 and the object B to be repaired can be avoided.
[0042] Furthermore, the laser repair device Z of the present application may further include a beam adjustment module 4, an optical module 5 and a focusing module 6.
[0043] Cooperating with Figures 4 to 6 as shown, the beam adjustment module 4 may correspond to the laser projection module 3. The beam adjustment module 4 may be configured to receive at least one pulsed laser beam L and to convert the at least one pulsed laser beam L into a first modulated laser beam FL. For example, the beam adjustment module 4 may be a laser beam expander. The beam adjustment module 4 may expand the laser spot of the pulsed laser beam L to generate a first modulated laser beam FL.
[0044] Next, cooperating with Figures 4 to 6 as shown, the optical module 5 corresponds to the beam adjustment module 4. The optical module 5 is configured to receive the first modulated laser beam FL and to convert the first modulated laser beam FL into a second modulated laser beam SL. For example, the optical module 5 may be a diffractive optical element (DOE) or a top-hat beam shaper DOE. The optical module 5 may be a lens or may be a long tube lens group. The optical module 5 may convert the laser spot of the first modulated laser beam FL into a spot with a specific pattern (such as a circle, a square or other geometric shapes), and may convert the first modulated laser beam FL into a flat-top light, thereby forming a second modulated laser beam SL.
[0045] Next, cooperating with Figures 4 to 6As shown, the focusing module 6 corresponds to the optical module 5. The focusing module 6 is configured to receive the second modulated laser beam SL and convert the second modulated laser beam SL into a flat-top laser beam TL. For example, the focusing module 6 can be a flat-field focusing lens (F-Theta Lens). The focusing module 6 can focus the second modulated laser beam SL into a flat-top laser beam TL with a predetermined aspect ratio and then project the flat-top laser beam TL onto a plurality of filler parts R1. Among them, the laser projection module 3, the beam adjustment module 4, the optical module 5, and the focusing module 6 can be arranged on the same optical path.
[0046] Therefore, the laser repair device Z of the present application can also be provided with a beam adjustment module 4, an optical module 5, and a focusing module 6 between the laser projection module 3 and the carrier module 1. And, the pulsed laser beam L projected by the laser projection module 3 is converted into a flat-top laser beam TL by the beam adjustment module 4, the optical module 5, and the focusing module 6 and projected onto a plurality of filler parts R1. Since the front end of the flat-top laser beam TL has a flat-top shape, when the flat-top laser beam TL is projected onto the filler part R1, the flat-top laser beam TL can avoid damaging the object to be repaired B or the polymer material layer B3 and only heat the filler part R1.
[0047] Furthermore, the laser repair device Z of the present application can also include an analysis module 7 and a beam splitting module 8.
[0048] Cooperate with Figures 4 to 6 As shown, the analysis module 7 is connected to the laser projection module 3. For example, the analysis module 7 can be a laser beam analysis device, and the analysis module 7 is electrically connected to the laser projection module 3.
[0049] Next, cooperate with Figures 4 to 6 As shown, the beam splitting module 8 corresponds to the analysis module 7. The beam splitting module 8 is configured to receive the first modulated laser beam FL, the second modulated laser beam SL, or the flat-top laser beam TL. For example, the beam splitting module 8 can be a cube beam splitter, a flat plate beam splitter, a polarization beam splitter, or other types of beam splitting optical elements; and, the beam splitting module 8 can be arranged between the beam adjustment module 4 and the optical module 5, between the optical module 5 and the focusing module 6, or between the focusing module 6 and the carrier module 1.
[0050] Among them, when the beam splitting module 8 can be arranged between the beam adjustment module 4 and the optical module 5 and the beam splitting module 8 receives the first modulated laser beam FL, the beam splitting module 8 can project a part of the beam of the first modulated laser beam FL onto the optical module 5 and project another part of the beam of the first modulated laser beam FL onto the analysis module 7, so that the analysis module 7 generates a first beam energy analysis signal accordingly, and the analysis module 7 transmits the first beam energy analysis signal to the laser projection module 3.
[0051] Alternatively, when the beam splitting module 8 can be disposed between the optical module 5 and the focusing module 6, and the beam splitting module 8 receives the second modulated laser beam SL, the beam splitting module 8 can project a part of the second modulated laser beam SL to the scanning module, and project another part of the second modulated laser beam SL to the analysis module 7, so that the analysis module 7 generates a second beam energy analysis signal accordingly, and the analysis module 7 transmits the second beam energy analysis signal to the laser projection module 3.
[0052] Or, when the beam splitting module 8 can be disposed between the focusing module 6 and the carrier module 1, and the beam splitting module 8 receives the flat-top laser beam TL, the beam splitting module 8 can project a part of the flat-top laser beam TL to the plurality of replenishing members R1, and project another part of the flat-top laser beam TL to the analysis module 7, so that the analysis module 7 generates a third beam energy analysis signal accordingly, and the analysis module 7 transmits the third beam energy analysis signal to the laser projection module 3.
[0053] Among the above, the first beam energy analysis signal, the second beam energy analysis signal, and the third beam energy analysis signal include at least one of spot shape, spot position, and beam energy.
[0054] Therefore, the analysis module 7 can transmit the first beam energy analysis signal, the second beam energy analysis signal, or the third beam energy analysis signal to the laser projection module 3; and the laser projection module 3 can selectively adjust at least one of the spot shape, spot position, and beam energy of the pulsed laser beam L according to the data of the first beam energy analysis signal, the second beam energy analysis signal, or the third beam energy analysis signal.
[0055] Furthermore, as shown in Figure 7 the laser repair device Z of the present application may further include a control module 9, and the control module 9 can be a control device. The control module 9 can be electrically connected to the carrier module 1, the replenishing material providing module 2, the laser projection module 3, the beam adjustment module 4, and the analysis module 7, and the control module 9 can be configured to control each of the above modules. Among them, the analysis module 7 can also transmit the first beam energy analysis signal, the second beam energy analysis signal, and the third beam energy analysis signal to the control module 9, and the control module 9 can drive the laser projection module 3 to selectively adjust at least one of the spot shape, spot position, and beam energy of the pulsed laser beam L according to the data of the first beam energy analysis signal, the second beam energy analysis signal, or the third beam energy analysis signal.
[0056] Furthermore, as shown in Figure 2 、 Figure 3 and Figure 7As shown, the laser repair device Z of the present application may further include a detection module 10. The detection module 10 is adjacent to the carrying module 1. The detection module 10 can be electrically connected to the laser projection module 3, the control module 9, or both. The detection module 10 can be configured to detect the heat condition of the conductive block C to correspondingly generate at least one heat data. For example, the detection module 10 can be a hyperspectral imaging detection device. After multiple filler parts R1 are sintered into the conductive block C, the laser repair device Z of the present application can perform spectral detection on the conductive block C through the detection module 10 to obtain the heat condition of the conductive block C itself or a partial area, and correspondingly generate heat data regarding the conductive block C itself or a partial area of the conductive block C, such as spectral data of the heat source distribution, but not limited thereto.

[0085] Next, cooperate with Figure 9 and Figure 10 As shown, the laser modulation unit 310 is adjacent to the pulsed laser generation unit 300. The laser modulation unit 310 can be configured to increase the repetition frequency of the laser L1 and generate a pulsed train laser L2 with multiple pulsed trains P1 - Pn based on the increased laser L1. For example, the laser modulation unit 310 can be an acousto - optic modulator (AOM) or other devices of the same type, and the repetition frequency of the pulsed train laser L2 can be between 0.5 - 10 GHz (for example, any positive integer between 0.5 - 10 GHz), but not limited thereto.

[0093] However, the examples cited above are only one feasible embodiment and are not intended to limit the present application.
[0094] Third Embodiment
[0095] Please refer to Figure 11 which is a schematic structural diagram of the laser repair device according to the third embodiment of the present application, and please also refer to Figures 1 to 10As shown in the figure, the laser repair device Z of this embodiment is substantially similar to the laser repair device Z of the above embodiment. Therefore, the setting or operation of the same components will not be described herein again. The difference between the laser repair device Z of this embodiment and the laser repair device Z of the above first embodiment is that, in this embodiment, the laser repair device Z of the present application may further include a scanning module 11, and the scanning module 11 is located between the optical module 5 and the focusing module 6. The scanning module 11 can be configured to receive the second modulated laser beam SL and selectively project the second modulated laser beam SL in at least one projection direction; wherein, the scanning module 11 can be a laser galvanometer scanning module with a scanning galvanometer, a laser focusing module with a fixed focusing processing head, or other types of galvanometer scanning modules. Among them, the laser projection module 3, the beam adjustment module 4, the optical module 5, the scanning module 11, and the focusing module 6 can be arranged on the same optical path.
[0096] For example, in cooperation with Figure 11 As shown, when the laser repair device Z of the present application is operating, after the laser projection module 3 projects at least one pulsed laser beam L, the beam adjustment module 4 can receive the at least one pulsed laser beam L and convert the at least one pulsed laser beam L into a first modulated laser beam FL. Then, the optical module 5 can receive the first modulated laser beam FL and convert the first modulated laser beam FL into a second modulated laser beam SL; wherein, the optical module 5 can convert the laser spot of the first modulated laser beam FL into a spot of a specific shape (such as a circle, a square, an elongated strip, a thick elongated strip, or other geometric shapes), and can convert the first modulated laser beam FL into a flat-top beam, thereby forming the second modulated laser beam SL.
[0097] Next, the scanning module 11 can receive the second modulated laser beam SL and selectively project the second modulated laser beam SL in at least one projection direction. Further, the scanning module 11 can include a first beam scanning unit 1100 and a second beam scanning unit 1101. The first beam scanning unit 1100 can correspond to the optical module 5 and the second beam scanning unit 1101 and be located between the optical module 5 and the second beam scanning unit 1101; while the second beam scanning unit 1101 can correspond to the first beam scanning unit 1100 and the focusing module 6 and be located between the first beam scanning unit 1100 and the focusing module 6, but not limited thereto. The first beam scanning unit 1100 can be a galvanometer capable of adjusting the displacement of the second modulated laser beam SL in a first axial direction (e.g., the direction of the X-axis or Y-axis); for example, the first beam scanning unit 1100 can reflect the second modulated laser beam SL according to a plurality of rotation angles in the X-axis direction (e.g., 0°, 30°, 60°, etc.), that is, the first beam scanning unit 1100 generates at least one rotation angle in the X-axis direction through rotational motion, and reflects the second modulated laser beam SL with a mirror at different angles. In contrast, the second beam scanning unit 1101 can be a galvanometer capable of adjusting the displacement of the second modulated laser beam SL in a second axial direction (e.g., the direction of the X-axis or Y-axis); that is, the second beam scanning unit 1101 can also generate a plurality of rotation angles in the Y-axis direction through rotational motion, and reflect the second modulated laser beam SL with a mirror at different angles. Wherein, the first axial direction is different from the second axial direction, and the first axial direction and the second axial direction are preferably perpendicular to each other. Therefore, when the optical module 5 converts the laser spot into an elongated or thick elongated (the length is greater than any side length of the surface of the object to be repaired B) spot, the scanning module 11 can project the second modulated laser beam SL in a linear (linear) manner and scan the object to be repaired B; and when the optical module 5 converts the laser spot into a circular or square (the shape is smaller than the size of the surface of the object to be repaired B) spot, the scanning module 11 can project the second modulated laser beam SL in a non-linear manner (e.g., S-shaped or other non-linear paths) and scan the object to be repaired B.
[0098] It is worth mentioning that in other embodiments, if the scanning module 11 adopts a galvanometer scanning module, the galvanometer scanning module can reflect the second modulated laser beam SL according to multiple rotation angles (for example, 0°, 30°, 60°, …); that is, the galvanometer scanning module performs a rotational motion to generate multiple rotation angles, so that the galvanometer scanning module reflects the second modulated laser beam SL with a mirror surface at different angles. Further, the operator can input a control instruction to the control module 9 according to the processing requirement, and the control module 9 can send a corresponding driving instruction to the galvanometer scanning module according to the control instruction, so that the galvanometer scanning module can perform corresponding driving rotation according to the driving instruction to generate multiple rotation angles, and further drive the galvanometer scanning module to reflect the second modulated laser beam SL with a mirror surface at different angles according to the processing requirement. In addition, in other embodiments, if the scanning module 11 adopts a laser focusing module, the laser focusing module can reflect the second modulated laser beam SL by a reflection angle; that is, the laser focusing module reflects the second modulated laser beam SL with a mirror surface at a fixed reflection angle.
[0099] Next, the focusing module 6 is used to receive the second modulated laser beam SL, convert the second modulated laser beam SL into a flat-top laser beam TL, and then project the flat-top laser beam TL onto a plurality of replenishing elements R1.

The replenishing material providing module 2 is adjacent to the carrying module 1, and the replenishing material providing module 2 is configured to provide a repair liquid R between the first conductive element B1 and the second conductive element B2, and the repair liquid R includes a plurality of replenishing elements R1. The laser projection module 3 is adjacent to the carrying module 1, and the laser projection module 3 is configured to project at least one pulsed laser beam L onto a plurality of replenishing elements R1 to sinter the plurality of replenishing elements R1 and drive the plurality of replenishing elements R1 to form a conductive block C. Wherein, the conductive block C electrically connects the first conductive element B1 and the second conductive element B2".
