[0032] The laser heating system for simulating chip heating according to an embodiment of the utility model will be described in detail below with reference to the accompanying drawings.
[0033] Reference Figure 1 and Figure 2 As shown, the laser heating system for simulating chip heating provided in the embodiment of the utility model includes: a housing 10, a laser module (not shown in the figure), a transmission optical fiber 20 and a control module (not shown in the figure). The laser module is arranged in the housing 10 and is used to output a laser beam; the transmission optical fiber 20 is connected to the laser module and is used to shape the laser beam into a square spot and output it; the control module is arranged in the housing 10 and is electrically connected to the laser module to control the laser module to output the laser beam.
[0034] Among them, most chips are usually square, so by shaping the laser beam into a square spot, the chip heating can be simulated more closely to reality and the energy distribution can be more uniform; it can be understood that the laser module is a semiconductor laser with a wavelength of 808nm-980nm, and the power of the laser module is 10±2% W. In the laser heating process, a laser with a wavelength of 980nm is usually used, which can more accurately simulate the chip heating.
[0035] The laser heating system for simulating chip heating provided by the utility model can control the laser module to output a laser beam through a control module, so that the laser beam can be shaped into a square spot through a conduction relationship and output to a specified position of a product shell for heating, so that when heat dissipation verification is performed on shells of different materials, the heating state of the chip during operation can be accurately simulated, the verification efficiency is higher, the R&D time is reduced, and the R&D risks and costs are reduced.
[0036] Specifically, a processing head 30 is also provided on the transmission optical fiber 20, and the processing head 30 is used to irradiate a square light spot to a specified position when operated. Among them, a power detection device can be equipped on the processing head 30 to monitor the laser power output by the processing head 30, so as to more accurately simulate the heating of the chip; and after the processing head 30 is irradiated to the specified position of the product shell, the square light spot can make the specified position heat up, so as to more accurately verify the heat dissipation difference of the product shell, and the operation is simpler and more convenient.
[0037] Specifically, the transmission optical fiber 20 includes a core layer 21, an outer cladding layer 22 and a coating layer 23, wherein the core layer 21 is used to transmit the laser beam; the outer cladding layer 22 surrounds the core layer 21; the coating layer 23 has at least two layers and surrounds the outer cladding layer 22; further, an optical cladding layer 24 is provided between the core layer 21 and the outer cladding layer 22, and the optical cladding layer 24 is adjacent to the processing head 30, and is used to shape the laser beam into a square spot and output it.
[0038] In this embodiment, the radial cross-section of the optical cladding 24 is a square ring structure with a side length of 400-1000um. When the laser module emits a laser beam, the laser beam is usually a circular spot. The laser beam is transmitted through the core layer 21, and the light wave is confined in the core layer 21 through the outer cladding 22 for propagation, so that the laser beam can be shaped into a square spot after passing through the optical cladding 24, thereby better simulating chip heating; optionally, the side length of the square spot is variable within a certain range, thereby being able to adapt to different types of chips to simulate heating, and having a wider range of applications.
[0039] As an optional embodiment, the housing 10 is further provided with a plurality of interfaces 40 , and the plurality of interfaces 40 are electrically connected to the control module.
[0040] In this embodiment, the multiple interfaces 40 may include a power interface 40, an RS232 interface 40, a control interface 40, etc., and are connected to a display device through each interface 40, so that when the simulated chip heats up, the laser power and heat data can be output and displayed.
[0041] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.
